[android-developers] ListView problem
This is the context: I have a TabActivity with three tabs,|Contacts|History|Caller| in the tab on contacts, I have another TabActivity. In this TacActvity I have set the tabwidget invisible and I use a personal layout on the top to change among tabs: |Server|Agenda|Directory| basically i use the onClick event to setCurrentTab in the TabHost. If I set a normal Activity on a TabContent its OK, the problem is when I set a ListActivity with a ListView as the TabContent,in that case the lisview hide the 3 buttons on the on the top, so I can no longer interact with those buttons. As you can see on the image Any ideas of why or how to solve this? -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] listview problem
Hi friends,
I have 2 edittexts ,ontouch of the first edittext it should a particular
listview and ontouch of second edittext it should show a different
listview in android.
I have used the below code
View currentView = linflater.inflate(R.layout.listview, null);
list1 =(ListView)currentView.findViewById(R.id.list);
ViewpreviousView = linflater.inflate(R.layout.listview1, null);
list2 =(ListView)previousView.findViewById(R.id.list);
edit1.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
list1.setVisibility(View.VISIBLE);
list2.setVisibility(View.INVISIBLE);
listView.removeView(currentView);
linearlayout.removeView(previousView);
linearlayout.removeView(previousView);
String[] names = new String[] { "Linux", "Windows7",
"Eclipse", "Suse",
"Ubuntu", "Solaris", "Android", "iPhone"};
// Create an ArrayAdapter, that will actually make the
Strings above
// appear in the ListView
list1.setAdapter(new ArrayAdapter(SearchClass.this,
android.R.layout.simple_list_item_1, names));
linearlayout.addView(currentView);
return false;
}
});
edit1.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
list1.setVisibility(View.INVISIBLE);
linearlayout.removeView(previousView);
linearlayout.removeView(currentView);
list2.setVisibility(View.VISIBLE);
String[] names1 = new String[] { "LOCATION ", "",
"Eclipse", "Suse",
"cc", "", "",
"iPhone"};
list2.setAdapter(new
ArrayAdapter(SearchClass.this, android.R.layout.simple_list_item_1,

linearlayout.addView(previousView);
return false;
}
});

[android-developers] ListView problem
In following a tutorial from "SAMS Android Application Development in
24 hours" I hit a problem with my first ListView example.
Basically, my java code is firing according to log messages I set but
my ListView does not display when I execute my app. The App runs fine
without crashing so syntactically all seems to be well.
Since I can't attach documents, please bear with me as I paste some
code but you can download the entire sample app from
http://www.icerge.com/android-sample-app-download
My layout file is called Menu.xml and is as below:
http://schemas.android.com/apk/res/
android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
The java file is called QuizMenuActivity.java and is as follows:
package com.androidbook.triviaquiz;
import android.os.Bundle;
import android.util.Log;
import android.widget.ArrayAdapter;
import android.widget.ListView;
public class QuizMenuActivity extends QuizActivity {
private final String LOGID = "Track";
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.menu);
Log.i(LOGID, "Begining!");
ListView menuList = (ListView)
findViewById(R.id.ListView_Menu);
/*String[] items=
{ getResources().getString(R.string.menu_item_play),
getResources().getString(R.string.menu_item_scores),
getResources().getString(R.string.menu_item_settings),
getResources().getString(R.string.menu_item_help) };*/
String[] items ={"test#1","test#2","test3","test#4"} ;
ArrayAdapter adapt = new ArrayAdapter(this,
android.R.layout.simple_list_item_1, items);
menuList.setAdapter(adapt);
Log.i(LOGID, "Reaching this point!");
}
}
Finally, there is a Menu_item.xml which defines my TextView that the
java file above attempts to write array data to. It is as follows:
http://schemas.android.com/apk/res/android";
android:layout_width="match_parent"
android:text="testing testing"
android:layout_gravity="center_horizontal"
android:shadowRadius="5"
android:gravity="center"
android:textColor="@color/listview_items_color"
android:shadowDx="3"
android:shadowDy="3"
android:textSize="@dimen/menuxml_item_size"
android:shadowColor="@color/listview_items_color_glow">
As I don't want to overwhelm you with code you will have to take my
word for it that all the resources are in place and are not the
problem.
Can anyone offer some insight? Please download the app from
http://www.icerge.com/android-sample-app-download to examine the code
better and see what I mean.
Thanks.

[android-developers] ListView problem is back.
Hello, I have a error "11-14 01:23:23.204: ERROR/AndroidRuntime(730): java.lang.IllegalStateException: The content of the adapter has changed but ListView did not receive a notification. Make sure the content of your adapter is not modified from a background thread, but only from the UI thread. ". This error was discussed earlier here. I took the advices given there, but they didn't solve problem completely. My ListView fills in without exception. But if I've begun to click (frequently) on elements of listview , while it is filling in, i see that error. I'm using the ListView + Cursor , and I'm sure that the cursor is updated from the main thread (via AsyncTask, also I tried Handlers with post() , but it works the same) I wrote specially simple project to show my problem, and it's here : http://listexample.googlecode.com/ I'm looking forward to your answers to know what I'm doing wrong.

[android-developers] ListView problem while scrolling
Hi everyone,
I am trying 4 days to solve this problem. I am trying to create the
following feature:
I have a ListView that the user can select an item. When the user selects
the item the text will turn to pink. The ListView shows 6 items at once.
You have to scroll to see other 6 and go on.
But there is a problem:
When i scroll the ListView the item No8, No15,... are pink too!
Any help, ideas (even if you think you are wrong) are welcomed. I am
freaking out more and more every day.
Thanks a lot for your time spent reading my issue!
Here is the code inside for my adapter:
public class MyListAdapter extends ArrayAdapter {
private Context ctx;
private String[] values;
private ArrayList mData =new ArrayList();
private ViewHolder holder=null;
private LayoutInflater inflater;
public MyListAdapter(Context context, int textViewResourceId, String[]
values) {
super(context, textViewResourceId, values);
ctx = context;
inflater = (LayoutInflater) ctx
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
this.values = values;
for (int i = 0; i < values.length; i++) {
addItem(values[i]);
}
}
public void addItem(final String item) {
mData.add(item);
notifyDataSetChanged();
}
@Override
public String getItem(int position) {
return mData.get(position);
}
@Override
public long getItemId(int position) {
return position;
}
@Override
public int getCount() {
// TODO Auto-generated method stub
return mData.size();
}
/* (non-Javadoc)
* @see android.widget.ArrayAdapter#getView(int, android.view.View,
android.view.ViewGroup)
*/
@Override
public View getView(int position, View convertView, ViewGroup parent) {
if(convertView==null){
convertView = inflater.inflate(R.layout.list_item, parent, false);
holder = new ViewHolder();
holder.textView =
(TextView)convertView.findViewById(R.id.item_textView);
convertView.setTag(holder);
}
else{
holder = (ViewHolder)convertView.getTag();
}
holder.textView.setText(mData.get(position));
holder.textView.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View view) {
for(int i=0; ihttp://groups.google.com/group/android-developers?hl=en
Re: [android-developers] ListView problem is back.
I'm pretty sure that if the size of the adapter changes while the layout is being calculated you will get this exception. All additions, deletions, and data updates should be done in the UI thread I think. Using an AsyncTask is one way to do this. Make sure that each piece of data your background process produces is added to the adapter in the safe methods of the AsyncTask.

Re: [android-developers] ListView problem while scrolling
You only ever setting the color to be pink. You need to set the color
to be not-pink as well, for cases where the row is recycled, was pink,
and now no longer is supposed to be pink.

[android-developers] ListView problem - items are shrank when while scrolling the view
Hi,
I found strange behavior in ListView.
I have ListView of TextView except from one entry that contains
ImageView.
when i on of the items is touched and scroll up and down the image is
re-sized to about 2/3 its original size! Usually, the image remains in
this smaller size when the user lifts his finger and stops scrolling.
The original size can be restored by tapping your finger on any of the
empty list cells.
any idea?
