[android-developers] List view and using a loader
Hello, i have problem with using this code:
developer.android.com/guide/topics/ui/layout/listview.html
I used the code, everything same, but i had error at this part:
getLoaderManager().initLoader(0, null, this);
This is exception. It has problem with "this":
(MainActivity looking like: public class MainActivity extends ListActivity
implements LoaderManager.LoaderCallbacks)
Error:(71, 27) error: method initLoader in class LoaderManager cannot be
applied to given types;
required: int,Bundle,LoaderCallbacks
found: int,,MainActivity
reason: cannot infer type-variable(s) D
(argument mismatch; MainActivity cannot be converted to LoaderCallbacks)
where D is a type-variable:
D extends Object declared in method
initLoader(int,Bundle,LoaderCallbacks)
Okey, so i tried to make new loader like:
android.app.LoaderManager.LoaderCallbacks loader = new
android.app.LoaderManager.LoaderCallbacks() {
public Loader onCreateLoader(int id, Bundle args) {
return new CursorLoader(getApplicationContext(),
ContactsContract.Data.CONTENT_URI,
PROJECTION, SELECTION, null, null);
}
public void onLoadFinished(Loader loader, Cursor data) {
mAdapter.swapCursor(data);
}
public void onLoaderReset(Loader loader) {
mAdapter.swapCursor(null);
}
}
And used "loader" instead of "this" (initLoader(0, null, loader)), but i
wasnt working too, because of incompatibilty Loader and CursorLoader
in:
public Loader onCreateLoader(int id, Bundle args) {
return new CursorLoader(getApplicationContext(),
ContactsContract.Data.CONTENT_URI,
PROJECTION, SELECTION, null, null);
}
Please, can someone help me with solving this problem?
Thanks very much, Sebastian :)

If I understand correctly, you want the selection of one item to select
one link, and another item selects another link (and so on, I assume).
Ok. Well, unless you left some bits in this code out, here's the problem:
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView? parent,
View view, int position,long id) {
Where's the code that should be here, getting and reacting to the
selection made by the user? Did you just leave this out? Or is it
just not there in the first place? If the former, something is wrong
in the code that goes here, but nobody can tell you more than that, as
you left it out, and nobody (as far as I know...) can read your mind.
If the latter, u...well, that would be THE problem.
}
});
static final String[] LISTITEMS = new String[] {
Philips Healthcare, samsung, siemens Healthcare, mindtree
};

Re: [android-developers] List view row background.
In the getView method of the adapter, use the index of the row to set
background to. Suppose every row is a textView, then
textView.setBackgroundColor(Color.BLACK) would do the trick.
For different indices, you could do this...
public View getView(int index, View convertView, ViewGroup parent) {
textView.setText()
...
...
if(index %2 == 0){
textView.setBackgroundColor(Color.BLACK);
}else{
textView.setBackgroundColor(Color.BLUE);
}
return textView;
}
Something like that I guess is what you are looking for. Hope that helps

Re: [android-developers] List view row background.
Ok, I kind of got it together. For the row, I'm setting the background to my bitmap image. For selection, I'm setting the ListView attribute: android:listSelector=@drawable/xxx It kind of works. But I can't see the selection. i.e. when a row is selected (or clicked) I don't see the color change. This happens when I set the background for the rows. To counter that I tried setting this attr: android:drawSelectorOnTop=true But the problem with that is that the row contents are completely hidden. What should I do in this case?

[android-developers] List View with Check box multiselection
Hi all,
In my application, i created a custom file adapter and i am using
ListView with checkboxes, upto this point everything working great.
But now i have to take the values of Checked listView items in an
Array list. In my list view, i am listing Files present on the SD card
so i have to take Files for further processing by storing it in an
Array List.
I am confused here how i pass multiple files for the processing, can
someone help me in how i pass checked Files to further processing, or
do i need to change my FileAdapter also ?
My Adapter class code :--
public class FileAdapter extends ArrayAdapterFile
{
Context context;
File[] files;
CheckBox Check;
public FileAdapter(Context context, File[] files)
{
super(context, -1, files);
this.context = context;
this.files = files;
}
Thanks

Re: [android-developers] List View with Check box multiselection
Hi Chander,
I wish if i could help with the whole source. The problem is the design.
let me tell you the real approach.
1. create a model class which holds the data that is name and checkbox with
setters and getters. below is the example
/** Holds Music data. */
private static class Music {
private String name = ;
private boolean checked = false;
public Music() {
}
have the setters and getters for name and checked
2.Create a View adapter class which holds the child view data. below is the
example
private static class MusicViewHolder {
private CheckBox checkBox;
private TextView textView;
public MusicViewHolder() {
}
public MusicViewHolder(TextView textView, CheckBox checkBox) {
this.checkBox = checkBox;
this.textView = textView;
}
public CheckBox getCheckBox() {
return checkBox;
}
public void setCheckBox(CheckBox checkBox) {
this.checkBox = checkBox;
}
public TextView getTextView() {
return textView;
}
public void setTextView(TextView textView) {
this.textView = textView;
}
}
3. your custom adapter which actally extends the Arrayadapter should be
like this
/** Custom adapter for displaying an array of Music objects. */
private static class MusicArrayAdapter extends ArrayAdapterMusic {
private LayoutInflater inflater;
public MusicArrayAdapter(Context context, ListMusic musicList) {
super(context, R.layout.simplerow, R.id.rowTextView, musicList);
// Cache the LayoutInflate to avoid asking for a new one each time.
inflater = LayoutInflater.from(context);
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
// Music to display
Music music = (Music) this.getItem(position);
// The child views in each row.
CheckBox checkBox;
TextView textView;
// Create a new row view
if (convertView == null) {
convertView = inflater.inflate(R.layout.simplerow, null);
// Find the child views.
textView = (TextView) convertView
.findViewById(R.id.rowTextView);
textView.setTextColor(Color.BLACK);
checkBox = (CheckBox) convertView.findViewById(R.id.CheckBox01);
convertView.setTag(new MusicViewHolder(textView, checkBox));
checkBox.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
CheckBox cb = (CheckBox) v;
Music music = (Music) cb.getTag();
music.setChecked(cb.isChecked());
}
});
}
else {
MusicViewHolder viewHolder = (MusicViewHolder) convertView
.getTag();
checkBox = viewHolder.getCheckBox();
textView = viewHolder.getTextView();
}
checkBox.setTag(music);
checkBox.setChecked(music.isChecked());
textView.setText(music.getName());
return convertView;
}
}
4.finally your setItemclicklisteners should be
Music music = listAdapter.getItem(position);
music.toggleChecked();
MusicViewHolder viewHolder = (MusicViewHolder) item
.getTag();
viewHolder.getCheckBox().setChecked(music.isChecked());
That's it. as i said, i have done this earlier, it requries the whole
process. bascially you need to create and store the data in private Music[]
musiclistarray;

Re: [android-developers] List View multiselection problem
Mohan, I have done this before, where i am reading all the music files in
SDCard and able to show it in Listview with checkbox.
Please follow the below points which will help you in resolving.
1. Create a class which extends the ArrayAdapter
2.In the getView method of the Adapterclass have the following.
// The child views in each row.
CheckBox checkBox;
TextView textView;
// Create a new row view
if (convertView == null) {
convertView = inflater.inflate(R.layout.simplerow, null);
// Find the child views.
textView = (TextView) convertView
.findViewById(R.id.rowTextView);
textView.setTextColor(Color.BLACK);
checkBox = (CheckBox) convertView.findViewById(R.id.CheckBox01);
convertView.setTag(new MusicViewHolder(textView, checkBox));
checkBox.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
CheckBox cb = (CheckBox) v;
Music music = (Music) cb.getTag();
music.setChecked(cb.isChecked());
}
});
}
in onCreate bind the Adapter with your list.
listAdapter = new MusicArrayAdapter(this, musicList);
mainListView.setAdapter(listAdapter);

Mohan, I have done this before, where i am reading all the music files in
SDCard and able to show it in Listview with checkbox.
Please follow the below points which will help you in resolving.
1. Create a class which extends the ArrayAdapter
2.In the getView method of the Adapterclass have the following.
// The child views in each row.
CheckBox checkBox;
TextView textView;
// Create a new row view
if (convertView == null) {
convertView = inflater.inflate(R.layout.simplerow, null);
// Find the child views.
textView = (TextView) convertView
.findViewById(R.id.rowTextView);
textView.setTextColor(Color.BLACK);
checkBox = (CheckBox) convertView.findViewById(R.id.CheckBox01);
convertView.setTag(new MusicViewHolder(textView, checkBox));
checkBox.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
CheckBox cb = (CheckBox) v;
Music music = (Music) cb.getTag();
music.setChecked(cb.isChecked());
}
});
}
in onCreate bind the Adapter with your list.
listAdapter = new MusicArrayAdapter(this, musicList);
mainListView.setAdapter(listAdapter);

[android-developers] List View based on Database Cursor Not Showing Full Screen and Scrolling
I am having a problem getting my list view based on retrieved data
from a database to show the full screen and scroll. For some reason
neither the fill_parent or wrap_content values for my layout height
setting is being recognized. Right now my view only shows about a
quarter of the screen. However, if I put in a hard codded number for
the height it works, but that is not a good solution because the user
can enter unlimited number of entries that could be displayed on the
list. Without the hard coded size I can see that something is being
displayed behind the list for a couple seconds. I am assuming it is
an error message but cannot figure out how to find out what it is
saying.
It worked correctly at one time but I cannot figure out what now is
preventing the screen from using the whole size with scrolling if
needed. The code I use is below.

Re: [android-developers] List View and Simple Cursor Adapter
getView() will be called many times, not necessarily only the number of times you might expect or in the order you expect. Please just make your getView() implementation be efficient and let Android call getView() as it sees fit.

[android-developers] list view with alpha transparency effect
I have a list view using a layout that has a background color of #8000. When I scroll the list, the list item background color change to a solid color, in this case black.

Use this: http://developer.android.com/reference/android/widget/AbsListView.html#setCacheColorHint(int) http://developer.android.com/reference/android/widget/AbsListView.html#attr_android:cacheColorHint Note that doing this means that ListView can't use important drawing optimizations, so on many devices this will cause scrolling to be noticeably less smooth.

[android-developers] List view problem
I have a list view which display multiple kinds of items (Basically 3). I have overridden all the methods, and it works almost fine. Basically, For those three types of views, I need to change the gravity to either left/right or center (Simple TextViews). This works. In addition to this, I also have different background images for these views. I don't understand why it doesn't work. It just picks up one image and keeps setting it to random items, and for some, I don't even get a background image. getItemViewType(int position) - Overridden getViewTypeCount() - Overridden (Always returns 3) I was going through the docs, and I found this. public int getViewTypeCount () Returns the number of types of Views that will be created by getView(int, View, ViewGroup). Each type represents a set of views that can be converted in getView(int, View, ViewGroup). If the adapter always returns the same type of View for all items, this method should return 1.

Re: [android-developers] List view problem
It probably means it won't be called by itself. Re: background. A ListView changes its item's backgrounds at runtime to show selection state, so you should not be changing the background of the root view of your items. As a workaround, inject another view group inside the item's top level layout, give it the same size, and change the background on that. -- Kostya 27.04.2011 22:17, Kumar Bibek пишет: What exactly does this This method will only be called when when the adapter is set on the the AdapterView. mean? -- Kostya Vasilyev -- http://kmansoft.wordpress.com -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] List view problem
Hmm, I tried injecting a view group at the root of the items, but still it doesn't work. Weird. When I put logs, correct view types get returned, and morever, the gravity stuff works fine, but the backgrounds just dont work. Damn!! I thought I knew list views very well.

Re: [android-developers] List view problem
I am a little confused here. I inflate a layout, which has a single TextView inside a LinearLayout. In the adapter, I use the convertView to recycle views, so, now I don't try to change the convertView's backgound, rather, I am now changing the LinearLayout's background. I also tried to change the TextView's background. Similar results. I have started feeling that there's a silly mistake somewhere, which I am not able to detect. However, strangely enough, the Logs say everything's fine.

[android-developers] list view: scrolling resizes the items in a weird way
Hi, I have a problem with the list view and its items. When scrolling up/ down the listview I noticed that the items slightly resize(about one pixel) and in my application it looks like ^. The divider between two items should be one pixel high(used default android behavior), but when scrolling the divider is sometimes 2 pixels or 0 pixels(not visible). This is bad since it looks like the two items form one list item. Has anyone a solution for this weird resizing problem when scrolling inside a listview? My development device is the HTC Wildfire with firmware version 2.1- update1. Emulator is set to:Android 2.1-update1, skin WVGA800 and hw.lcd.density=240. ?xml version=1.0 encoding=utf-8?

Re: [android-developers] list view row number.
The position parameter to the onListItemClick() method is the row number,
insofar as such a concept exists.

[android-developers] List view with clickable items and clickable buttons in the items
Hi, I'm trying to implement a list view where each item consists of some text, an image, and two buttons. Clicking on the buttons should perform one action (sharing in this case), and clicking anywhere else in the item should perform another action (in this case, start an activity to provide a more detailed view of the item.) I can't seem to find the right combination of focus settings to allow this. Out of the box I was getting clickable buttons but an otherwise unclickable list item behind them. I added android:focusable=false android:focusableInTouchMode=false to the buttons, and now I have a clickable liste item in the background and the buttons are clickable, except if i click the general list item area, BOTH buttons highlight (and a I presume get click events?) How can I set it up so that I can detect button clicks within the list items as well as general/elsewhere clicks in the list item?

These are not guaranteed to be in the same order as you scroll the list and items are cycled, AFAIK. My guess is your items are being re-arranged and you're seeing the behavior you're seeing since you're not updating the tag on the button where you store in the index. I would recommend you completely update the view you're getting even if there is an existing convertView. In this case just do c.button.setTag(position) after the if / else clause instead of inside the if clause. - TreKing - Chicago transit tracking app for Android-powered devices http://sites.google.com/site/rezmobileapps/treking -- You received this message because you are subscribed to the Google Groups Android Developers group.

I haven't used it but I think the ListView has a headerView you can set that's different that the main contents. Maybe that will work?

[android-developers] List View multiple choice slow to update
I am having trouble with a list aspect of my app. Essentially, it has
a multiple choice listview(simple_list_item_multiple_choice) on the
right and a text view on the left.
When an item of the list view is checked off, I want to add it to the
text view or remove it if it gets unchecked. This almost works except
that the updates on what is checked seems to be one click behind.
I.E. check something off the first time and nothing happens. Uncheck
it or check something else and the first thing appears. Check below
the list choices (but still in the list view) and it updates.
I was not able to get setOnItemSelectedListener to respond as all, so
I am using onTouchListener:
private void loadContacts(){
String[] contacts = new String[] {People.NAME};
final String[] cols = new String[] {
Contacts.People.NAME,
Contacts.People._ID,
Contacts.People.NUMBER
};
final Cursor C = getContentResolver().query
(People.CONTENT_URI, cols, null, null, null);
startManagingCursor(C);
lv = (ListView)findViewById(R.id.contact_list);
ListAdapter mAdapter = new SimpleCursorAdapter(this,
android.R.layout.simple_list_item_multiple_choice,
C,
cols,

[android-developers] List view scrolling while setPadding
Hi All, I have an list view in my project. If the list view items are more than that page (screen size) means i am able to see the scroll bar in the right side. If i am restricting in to a default size using setPadding (reducing the height of the view). This time i am not getting the scroll bar. That means if the items are more that the device screen size scroll bar is showing. Other wise scroll bar is not showing. Is there any specific reason in this? How do i handle for this? Thanks in advance, Muthu Kumar K. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] List View not properly updated from AsyncTask
Hi Everyone,
After digging with the APIs I still cannot figure out how the
AsyncTask properly works and why some behavior occur.
I'm trying to achieve one contact list that can be updated from a
background async task very frequently. There are situations where
invoking UI updates from the background thread just freeze the UI as
you see in example #2. or make the list not to react properly to
finger as a regular contact list. Can anyone give me some hint on how
to achieve the expected behavior?
I added here the activities that form my project (sorry for the lenght
of the post, my idea was to share the complete problem with everyone)
Example 1: Contact list without background task. This code contains
the behavior of a default contact list. This code produce the expected
behavior in responsive for the user but do not update. This activity
shows the ideal response for a contact list.
package com.pp.lists;
import android.app.ListActivity;
import android.content.Intent;
import android.hardware.SensorManager;
import android.os.Bundle;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.Button;
public class List1 extends ListActivity implements
View.OnClickListener {
Button btnBack = null;
SensorManager sensorManager = null;
String[] items = { lorem, ipsum, dolor, sit, amet,
consectetuer, adipiscing, elit, morbi, vel,
ligula, vitae, arcu, aliquet, mollis, etiam,
vel, erat, placerat, ante, porttitor,
sodales, pellentesque, augue, purus, lorem,
ipsum, dolor, sit, amet, consectetuer,
adipiscing, elit, morbi, vel, ligula, vitae,
arcu, aliquet, mollis, etiam, vel,
erat, placerat, ante, porttitor, sodales,
pellentesque, augue, purus, lorem, ipsum,
dolor, sit, amet, consectetuer, adipiscing,
elit, morbi, vel, ligula, vitae, arcu,
aliquet, mollis, etiam, vel, erat, placerat,
ante, porttitor, sodales, pellentesque,
augue, purus, lorem, ipsum, dolor, sit,
amet, consectetuer, adipiscing, elit, morbi,
vel, ligula, vitae, arcu, aliquet, mollis,
etiam, vel, erat, placerat, ante,
porttitor, sodales, pellentesque, augue,
purus };
/** Called when the activity is first created. */
@Override
public void onCreate( Bundle savedInstanceState ) {
super.onCreate(savedInstanceState);
setContentView(R.layout.listdemo);
setListAdapter(new ArrayAdapterString(this,
R.layout.listitem, R.id.label, items));
btnBack = (Button) findViewById(R.id.btnBackFromList);
btnBack.setOnClickListener(this);
}
public void onClick( View arg0 ) {
if ( btnBack == arg0 ) {
startActivity(new Intent(this, Main.class));
}
}
public void onResume() {
System.out.println(List1.onResume!);
super.onResume();
}
public void onPause() {
System.out.println(List1.onPause!);
super.onPause();
}
}
Example 2: This example update the contact list very frequently
properly but without freezing DO NOT allow the user to even scroll.
package com.pp.lists;
import android.app.ListActivity;
import android.content.Intent;
import android.os.AsyncTask;
import android.os.Bundle;
import android.os.Handler;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.EditText;
import android.widget.ListView;
public class List2 extends ListActivity implements
View.OnClickListener {
Button btnBack = null;
Handler handler = new Handler();
String[] items = { lorem, ipsum, dolor, sit, amet,
consectetuer, adipiscing, elit, morbi, vel,
ligula, vitae, arcu, aliquet, mollis, etiam,
vel, erat, placerat, ante, porttitor,
sodales, pellentesque, augue, purus, lorem,
ipsum, dolor, sit, amet, consectetuer,
adipiscing, elit, morbi, vel, ligula, vitae,
arcu, aliquet, mollis, etiam, vel,

purus };
private ArrayAdapter adapter = null;

[android-developers] List View setTextFilterEnabled(true) and returned id
Hi, Is there a way to use a List View with setTextFilterEnabled(true) and get the position into the unfiltered list returned to onItemClick? E.G. If I have a list:- - Zero - One - Two - Three And a user types T o filter the list to:- - Two - Three When a user clicks on Two in the filtered list, I would like the id or position returned to onItemClick to be 2. But instead it returns 0, which is expected as it is the first item in the filtered list. But what's the best way to get the position in the unfiltered list? Thanks a lot, Ryan FYI My code is as follows:- ListString list; ArrayAdapterString array; list.add(Zero); list.add(One); list.add(Two); list.add(Three); array = new ArrayAdapterString (this,android.R.layout.simple_list_item_1, list); setListAdapter(array); this.getListView().setOnItemClickListener(this); this.getListView().setTextFilterEnabled(true); -- --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.
