subject:"\[android\-developers\] Is there a docment on getView\?"

Hello

The getView() call for arrayadapter is blank.  Is there a document
which describes how it works?

I have overridden it in order to change the text color of items in a
list view.  So far, I can't find any code which works.

I've tried this:

public class MyAdapterT extends ArrayAdapterT {

public MyAdapter(Context context, int textViewResourceId, T[] objects) {
super(context, textViewResourceId, objects);
}
// context, int, T[]

@Override
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
View row;
row = super.getView(position, convertView, parent);
TextView text;
text = (TextView) row.findViewById(R.id.listView1);
text.setTextColor(0x64788e);
return row;
}
}


I don't know if I am supposed to call getView in the main code or not,
but this will most certain crash the app.
The super.getView call seems to get a row in the list.  It seems  that
you then need to get the view associated with that row.  I have no
idea how to do that. I don't have resource id's for the individual row
items.  Here, I tried to use the  resource id of the list itself.
There is not a View.getChild() like call.

Re: [android-developers] Is there a docment on getView()?

1:

http://developer.android.com/reference/android/widget/Adapter.html#getView(int,
android.view.View, android.view.ViewGroup)

2:

Yes, you're supposed to call the base class in your case, the ArrayAdapter
will be doing most of the work for you, inflating new or reusing existing
row layouts.

3:

Use view ids that are relevant to (used inside) your actual row item layout.

I very much doubt that R.id.listView1 is it.

4:

view.findViewById() is the getChild call you're looking for, using an id to
locate the view. Use correct id value and it should work.

The docs are your friend:

You're not.

but this will most certain crash the app.


When this happens, debug your app.


 The super.getView call seems to get a row in the list.


Nope.


 It seems  that you then need to get the view associated with that row.


Yup.


 I have no idea how to do that.


You make it or re-use convertView.


 I don't have resource id's for the individual row items.


You should, it's your project.


 Here, I tried to use the  resource id of the list itself.


That makes no sense.

I don't know what that means.

Re: [android-developers] Is there a docment on getView()?

Just to clarify 2:

I meant calling super.getView from your adapter's getView, assuming it's  a
subclass of ArrayAdapter.

Do not call adapter.getView from outside the adapter's code, that's
meaningless.

Now the view ids What layout id do you use to initialize the adapter?
Perhaps android.R.layout.something?

A side note: my suggestions here are just to patch up things based on the
route you've already headed down (using ArrayAdapter).

One day, as your knowledge grows, you'll want to throw away the
three-wheeled bicycle (ArrayAdapter) and create your own, perhaps by
extending BaseAdapter.

 I did :
                MyAdapterString adapter = new
 MyAdapterString(this,android.R.layout.simple_list_item_1, values);

You will notice that this is android.R.layout.simple_list_item_1. You
did not write this layout. Usually, if you are going to go to the
trouble of overriding getView(), you will use your own layout file for
the rows, so you have greater control. For example, if you use your
own layout file for the rows, then you are the one responsible for
setting your own view IDs.

 For what it is worth, I can do this:
         public View getView(int position, View convertView, ViewGroup parent) 
 {
         TextView text = new TextView(getContext());
         text.setText(Hi, I am position  + position);
         text.setTextColor(Color.parseColor(#64788e));
         return  text;
        }
 That will set the text color to blue, but it will also change the text
 I put in the list.

You are welcome to replace Hi, I am position  + position with your
actual data associated with that position. In this case, you are
telling Android not to bother inflating
android.R.layout.simple_list_item_1, but instead set the rows to be
what you are specifying here.

This is all covered in that excerpt that I linked to in the previous thread:

It is once you get the hang of it.

They do, but your hanging the wrong things on the hooks =).



Here's the general process for binding your data to a list view.

Create a custom class that is your data model that will be represented in
your UI. It has the properties you care about displaying in the list. In
this case, the text and color.

class MyType
{
 String Text;
 int Color;
}

Your ListAdapter is typed using your custom class.

ArrayAdapterMyType adapter = new ArrayAdapterMyType();

Then in your getView():

MyType selection = getItem(position);
CustomViewToReturn view = convertview != null convertView :
inflateFromXML(my_view_layout);
populateViewWithSelection(selection, view); // Set text and color on the
view using your object's state
return view;

Re: [android-developers] Is there a docment on getView()?

Aha!

android.R.layout.simple_list_item_1 is defined in the platform, you can
find it under your Android sdk
directory/platforms/platform-version/data/res/layout (that data/res is
very useful to look up things):

The whole layout is a TextView, and its id is @android:id/text1, which,
on the Java side of things, is android.R.id.text1.

So you'd do something like.

   @Override
   public View getView(int position, View convertView, ViewGroup
parent) {
   View row = super.getView(position, convertView, parent);
*   TextView text = (TextView) row.findViewById(android.R.id.text1);
*   text.setTextColor(0x64788e);
   return row;
   }

Or just this, knowing that the layout is just one TextView:

*TextView text = (TextView) row;*

The direct typecast should work for the hello-listview sample, as that also
uses a row layout containing a single TextView with no children (and no id,
so findViewById won't work here).

Kostya,

Tip of the hat to you.  That worked.  It will set all the items to
blue text. I appreciate your help a lot.

Now, is there a simple way to do this selectively?  I saw you could
tag items and then look based upon a tag.  Perhaps that will work?  I
would prefer that the class which creates the array adapter and list
view set the tag for the color and the array adapter to draw the line

 Or just this, knowing that the layout is just one TextView:

 TextView text = (TextView) row;

 The direct typecast should work for the hello-listview sample, as that also
 uses a row layout containing a single TextView with no children (and no id,
 so findViewById won't work here).

Re: [android-developers] Is there a docment on getView()?

Ok, great.

One simple thing you can do is to check the item's position, e.g. set odd
items to blue and even items to red (just to pick an example).

Beyond that, consider creating a proper data item class.

The adapter's getView would then examine the data item at the requested
position and make the decision on how to present it, based on its field
values (e.g. names starting with A are red, starting with B are green,
the rest are blue).

Also consider extending BaseAdapter rather than ArrayAdapter - it's just a
little bit more work, but should really clarify things for you.

Android can set different colors on TextViews in a list.

Re: [android-developers] Is there a docment on getView()?

Correct.

Since Android is not true Java, you can't call methods of one object from
another object.

An unfortunate limitation that is hopefully fixed some day (version 19.0?
Peppermint Pattie?)

/tongue firmly planted in cheek

You can call some methods of the activity from the adapter, or you can pass
some information from the activity into the adapter, or come up with some
other way.

I assure you, styling list view items based on some logic is definitely
possible. Just look at the Gmail app on your phone, for a start.

Re: [android-developers] Is there a docment on getView()?

Yes, I would think it is possible, but not in this version. Its
possible to set all line items to the same value.  However, its not
possible to set the colors on a case by case value using the provided
api.

This code will set all the line items to blue:

public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
View row;
row = super.getView(position, convertView, parent);
TextView text;
//  text = (TextView) row.findViewWithTag(2);
text = (TextView) row.findViewById(android.R.id.text1);
text.setTextColor(Color.parseColor(#64788e));
return row;
}

I tweaked it to use the tag like so:
public View getView(int position, View convertView, ViewGroup parent) {

  View row = super.getView(position, convertView, parent);
  TextView text = (TextView) row.findViewWithTag(99);
  // if this row has been tagged with the marker, set the color to blue
  if (null != text) {
text.setTextColor(Color.parseColor(#64788e)); 
  }
  // This will set all row items to be blue.
//  text = (TextView) row.findViewById(android.R.id.text1);
  return row;
}

But the api does not allow you to set a tag outside this code so that
the routine can change the text color based on the tag.

ie.

View rowView;
int listCount;
View fooView;
listCount = adapter.getCount();  // this says 6 items in array
int count = -1;
count = theList.getCount();  // this also says 6 items in teh view
for (int i=0;inumRows;i++) {
// If it is the 2nd or 5th item, tag it so that it will be
displayed in blue.
if (i==2 || i==5) {
fooView = (View) theList.getItemAtPosition(i);  // this 
line
has a bug and will not work as described.
fooView.setTag(99);
}   
 }

public Object getItemAtPosition (int position)

Since: API Level 1
Gets the data associated with the specified position in the list.
Parameters

positionWhich data to get
Returns

The data associated with the specified position in the list

If you try to get this data, it raises an exception.

Re: [android-developers] Is there a docment on getView()?

Yes it is possible to set colors on a case by case basis using the provided

It's just that the provided API is not structured the way you expect.

Create a data item class with fields to base the logic on
Extend BaseAdapter
Override getView
Check the data item fields and make the decision
Optionally, delegate to a method in the activity, an appearance manager
object, or make the decision in some other way.

Yes it is. Please stop blaming the platform for your lack of understanding
it. I already explained how you can create a data-model that holds the
unique color per item that you then set on the View.

But the api does not allow you to set a tag outside this code so that the
 routine can change the text color based on the tag.


Yes it does. But using the Tag property to achieve this is overkill and
ugly anyway.

No, if you don't know how to use this function and use it incorrectly, then
it raises an exception.

At this point I have to suggest to you that you take a step back, get
yourself a good book, and review the documentation thoroughly and go
through the samples. You are apparently confused about a number of things
with how the adapters work and are not going to get anywhere until you
understand what they are and how they work.

Good luck.

Re: [android-developers] Is there a docment on getView()?

Sadly I appreciate your help, but I don't think it will work. I've
already done an override of the getview call. The higher level logic
which knows which items can specify the draw color can not communicate
it to the lower level. The code samples, i have seen set all the
colors in a list. I don't see any which set colors on a line by line
basis. Probably the gmail example you gave uses private api calls
since the code is not online anywhere.

It's just that the provided API is not structured the way you expect.

Create a data item class with fields to base the logic on
Extend BaseAdapter
Override getView
Check the data item fields and make the decision
Optionally, delegate to a method in the activity, an appearance manager
object, or make the decision in some other way.

 Yes it is. Please stop blaming the platform for your lack of understanding
 it. I already explained how you can create a data-model that holds the
 unique color per item that you then set on the View.


I'm not blaming anyone or the api. I am simply saying it has a bug.
Someone might want to look into it.


 But the api does not allow you to set a tag outside this code so that the
 routine can change the text color based on the tag.


 Yes it does. But using the Tag property to achieve this is overkill and ugly
 anyway.

Sorry, but it is the only thing provided by the api and its not the
settag which raises the exception.  It is the getitematpostion call.
It says it gets the data at position x.  When this call is made it
raises and exception.  That is the bug. It should return null if it
does not exist. Raising an exception sounds like a bug.



 If you try to get this data, it raises an exception.


 No, if you don't know how to use this function and use it incorrectly, then
 it raises an exception.



I am not using the data from the call and getting an exception.  I am
making the call and getting an exception.



 At this point I have to suggest to you that you take a step back, get
 yourself a good book, and review the documentation thoroughly and go through
 the samples. You are apparently confused about a number of things with how
 the adapters work and are not going to get anywhere until you understand
 what they are and how they work.

 Good luck.

 The higher level logic which knows which items can specify the draw color
 can not communicate it to the lower level.


Yes it can. Unless this is a specific design restriction you've imposed,
there is nothing in the language or API preventing you from passing this
information down, one way or the other.


 The code samples, i have seen set all the colors in a list. I don't see
 any which set colors on a line by line basis.  Probably the gmail example
 you gave uses private api calls since the code is not online anywhere.


You can't find an example, therefore it's a private api? You've got to be
shitting me. Look up any todo app - almost all of them allow you to label /
color items differently based on what tags / lists / priorities / whatever
is associated with them. So you believe all of these apps must be employing
private apis because you can't figure out how to do it?


If you truly believe this is impossible, just abandon your app - it's only
going to get worse from here out.

Re: [android-developers] Is there a docment on getView()?

That's the debugger's stack trace, not the logcat stack trace.

Press F8 a few times until your device displays the application
stopped unexpectedly.

Then check the logcat panel in Eclipse and post the entire stack trace,
especially the stuff after Caused by:

Yes it is. Please stop blaming the platform for your lack of
understanding
it. I already explained how you can create a data-model that holds the
unique color per item that you then set on the View.

I'm not blaming anyone or the api. I am simply saying it has a bug.
Someone might want to look into it.

But the api does not allow you to set a tag outside this code so
that the
routine can change the text color based on the tag.

Yes it does. But using the Tag property to achieve this is overkill
and ugly
anyway.

Sorry, but it is the only thing provided by the api and its not the
settag which raises the exception. It is the getitematpostion call.
It says it gets the data at position x. When this call is made it
raises and exception. That is the bug. It should return null if it
does not exist. Raising an exception sounds like a bug.

If you try to get this data, it raises an exception.

No, if you don't know how to use this function and use it
incorrectly, then
it raises an exception.

I am not using the data from the call and getting an exception. I am
making the call and getting an exception.

At this point I have to suggest to you that you take a step back, get
yourself a good book, and review the documentation thoroughly and go
through
the samples. You are apparently confused about a number of things
with how
the adapters work and are not going to get anywhere until you
understand
what they are and how they work.

Good luck.

Re: [android-developers] Is there a docment on getView()?

Hello Treking, Kostya, Romain-Guy,

Ok, I removed the breakpoint, ran it, hit F8 until I got logcat
output. I selected all the red/orange text and exported to a textfile.
 This is the result.  (I hope I am giving you the answer you request)

This looks like the getItemAtPosition is returning a string instead of
a view.  Is this a list of views or a list of strings?

getItemAtPosition returns the data object at the specified position by
calling the list view adapter's getItem(). It's a convenience method.

So yes, in your case the return value would be a String.

It does not return the view for that item (for one thing, it may be
scrolled off the screen and not exist at the time).

Um, and I think a few ppl already mentioned it in this thread.

Re: [android-developers] Is there a docment on getView()?

2012-01-05 Thread Kristopher Micinski

Well it goes to the adapter, which will return Objects, which you then
must cast to the appropriate type, in your case it's obviously a
String.  As RomainGuy (whom you should listen to, right, as he is a
framework engineer) said in the previous thread, you get the actual
views from getChild, this simply delegates to the apater...

Then the problem is exactly what others have described earlier in this
thread. Your list adapter contains strings (and you should know what
it contains since you created it) and you attempt to cast one of these
strings into a View.

Ok. So I appreciate the help.  Here is the summary:

if (i==2 || i==5) {

fooString = (String) theList.getItemAtPosition(i);
Log.d(TAG, position +i+has string + 
fooString);
//  fooView = (TextView) theList.getChildAt(i);
//  Log.d(TAG, position +i+has  view id 
+fooView.getId());

//  fooView.setTag(99);
}

This code will work.  The stuff that is commented out pertaining to
getChildAt does not.  I'll try to get that working.  I suspect it will
not work since the view is not up and running yet.  As it is now, it
will crash when the getChild call is made.

Thanks for the help, this is becoming more clear. Pity the docs were
not more clear. returns the data is so generic.

 Hello

 Ok. So I appreciate the help.  Here is the summary:

            for (int i=0;icount;i++) {
                // If it is the 2nd or 5th item, tag it so that it will be
 displayed in blue.
                if (i==2 || i==5) {
                        listCount = adapter.getCount();
                        count = theList.getCount();
                        fooString = (String) theList.getItemAtPosition(i);

That might be your interpretation too.  I think most people would
argue (since most people realize that the list is an adapter backed
view) that indeed 'the data' would make much more sense as the thing
in the adapter, preferring to call the GUI object 'the view.'

I have actually found that -- while necessarily incomplete (to the
extent that it's impossible logistically to document everything)  --
the Android API documentation is extremely high quality: assuming you
have some knowledge of how the framework fits together.  (Which is why
the documentation is simply that, a reference rather than a tutorial.)

Hello Kris,

Yes, that is a good way to put it.  Thanks for the info.
