Album Art Drawable Not Showing Up in ListView [Android]

I have been trying to figure this out for days, but can't seem to find the solution.
The problem is that even after getting the album art bitmap from MediaStore, and converting it to a drawable, it is assigned to an ImageView in a custom ListView layout via HashMap (String, Object), but finally after running on actual device and emulator, no album art is shown.
No LogCat error either. The ImageView of the custom listview layout does not show the album art.
public class AllSongs extends Fragment
{
Bitmap bitmap = null;
BitmapDrawable drawable = null;
private ArrayList<HashMap<String,Object>> list = new ArrayList<HashMap<String,Object>>();
private HashMap<String, Object> item;
private SimpleAdapter sa;
private ListView listview;
...
}
#Override
public void onViewCreated(View view, Bundle savedInstanceState)
{
...
AsyncTaskRunner runner = new AsyncTaskRunner();
runner.execute("500");
}
private class AsyncTaskRunner extends AsyncTask<String, String, String>
{
#Override
protected String doInBackground(String... params) {
getAllMusicFiles();
return "Done!";
}
#Override
protected void onPostExecute(String result) {
super.onPostExecute(result);
listview.setAdapter(sa); //Set all the file in the list.
}
}
private void getAllMusicFiles() {
// TODO Auto-generated method stub
//Some audio may be explicitly marked as not being music
String selection = MediaStore.Audio.Media.IS_MUSIC + " != 0";
String[] projection = {
MediaStore.Audio.Media.TITLE,
MediaStore.Audio.Media.ARTIST,
MediaStore.Audio.Media.ALBUM,
MediaStore.Audio.Media.ALBUM_ID
};
Cursor cursor = getActivity().getApplicationContext().getContentResolver().query(
MediaStore.Audio.Media.EXTERNAL_CONTENT_URI,
projection,
selection,
null,
null);
while(cursor.moveToNext()){
item = new HashMap<String,Object>();
String title = cursor.getString(cursor.getColumnIndexOrThrow(MediaStore.Audio.Media.TITLE));
String artist = cursor.getString(cursor.getColumnIndexOrThrow(MediaStore.Audio.Media.ARTIST));
String album = cursor.getString(cursor.getColumnIndexOrThrow(MediaStore.Audio.Media.ALBUM));
long albumId = cursor.getLong(cursor.getColumnIndexOrThrow(MediaStore.Audio.Media.ALBUM_ID));
final Uri ART_CONTENT_URI = Uri.parse("content://media/external/audio/albumart");
Uri albumArtUri = ContentUris.withAppendedId(ART_CONTENT_URI, albumId);
ContentResolver res = context.getContentResolver();
InputStream in;
try { // Yes, the album art has been found. I am sure of this.
if(bitmap != null)
{
bitmap.recycle();
bitmap = null;
if(drawable != null)
{
drawable = null;
}
}
in = res.openInputStream(albumArtUri);
bitmap = BitmapFactory.decodeStream(in);
drawable = new BitmapDrawable(getResources(), bitmap);
} catch (FileNotFoundException e) { // Album not found so set default album art
e.printStackTrace();
drawable = (BitmapDrawable) getActivity().getResources().getDrawable(R.drawable.default_albumart);
}
item.put("icon", drawable);
item.put("title", title);
item.put("artist", artist);
list.add(item);
if(cursor.isLast())
{
sa = new SimpleAdapter(getActivity(), list,
R.layout.custom_listview_layout,
new String[] {"icon", "title","artist" },
new int[] {R.id.icon,R.id.title, R.id.artist});
}
}
}
I have detected that the drawable may be the one causing the image to not be shown because if I replace -
item.put("icon", drawable);
with -
item.put("icon", R.drawable.default_albumart);
it shows the default album art.
Any idea what's causing this?

It's your adapter implementation is causing the problems, not the Drawable.
Look at these two lines of code:
item.put("icon", drawable) - this puts a Drawable object to your hashmap
item.put("icon", R.drawable.default_albumart) - this puts an int value to your map, but as map only works with objects, it is autoboxed before being put there
Thus, the problem is that your adapter works fine with integer identifiers of drawables, but not the drawables themselves. These are the constraints of SimpleAdapter
To solve this issue I would suggest you to implement your custom CursorAdapter. Its implementation is simply straightforward, and will save you from unnecessary steps, such as creating unnecessary lists, hashmaps etc, wasting app memory.
Feel free to ask anything else in comments, good luck!

The answer was given correctly by Drew but here is how it was finally implemented. Here are the changes -
private void getAllMusicFiles() {
// TODO Auto-generated method stub
//Some audio may be explicitly marked as not being music
String selection = MediaStore.Audio.Media.IS_MUSIC + " != 0";
String[] projection = {
MediaStore.Audio.Media._ID, // this is required acc to documentation
MediaStore.Audio.Media.TITLE,
MediaStore.Audio.Media.ARTIST,
MediaStore.Audio.Media.ALBUM,
MediaStore.Audio.Media.ALBUM_ID
};
cursor = getActivity().getApplicationContext().getContentResolver().query(
MediaStore.Audio.Media.EXTERNAL_CONTENT_URI,
projection,
selection,
null,
null);
getActivity().startManagingCursor(cursor);
listview.setAdapter(new CustomCursorAdapter(context, cursor));
}
#Override
public void onDestroy() {
// TODO Auto-generated method stub
if(cursor != null)
{
getActivity().stopManagingCursor(cursor);
cursor.close();
}
super.onDestroy();
}
removed the AsyncTask as it wasn't here required anymore.
#Override

runner.execute("500");

GetView method from ArrayAdapter getting called onScroll up and down

I have a Custom ArrayAdapter that has a getview method, the thing is that method is being called for different views if i scroll down and up, and this make this views load again (e.g. downloading an image).

This is because in your getView() you do not consider the position. You always set the bitmap to image2 which is the most recent bitmap: holder.image.setImageBitmap(image2);
I think you misunderstood how get view works. The getView() method is called for each item in the list when you notifyDataSetChanged().
The solution is to keep reference to the different bitmaps in a list (or elsewhere.. i am just giving a possible solution),
List<Bitmap> images = new ArrayList<>();
When you get the image from the result, add it to the images list.
image2 = Bitmap.createScaledBitmap(thumbnail, imageWidth , imageHeight, true);
images.add(image2)
Finally, setImageBitmap based on the position of the item during getView()
holder.image.setImageBitmap(images.get(position));

You can use Android Movie class that is able to decode gifs.
Movie.decodeStream(InputStream is);

Use WebView rather then ImageView and loadUrl in WebView.

you have to use gif decorder class for that and set it in inflact view so you can set two view in single activity or screen.

Use the Glide image loading library, it has built-in support for GIFs and the syntax is the same loading a JPEG file:
Glide.with(this).load("http://.../anim.gif").into(imageView);
See the wiki for more and run the Gihpy sample to be amazed :)

//-----------------GIF Image view ------------
holder.imgAdd.getSettings().setJavaScriptEnabled(true);
holder.imgAdd.setWebChromeClient(new WebChromeClient() {
public void onProgressChanged(WebView view, int progress)
{
activity.setTitle("Loading...");
activity.setProgress(progress * 100);
if(progress == 100)
activity.setTitle(R.string.app_name);
}
});
holder.imgAdd.setWebViewClient(new WebViewClient() {
#Override
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl)
{
// Handle the error
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url)
{
view.loadUrl(url);
return true;
}
});
holder.imgAdd.loadUrl(imgUrl);

multiple attachments but only selected ones

I have my main view with images and checkboxes associated with them and a send email button. When I click on the checkboxes and select send email button I should be redirected to the email page where the selected images must be attached. Here is my code.
please help me out

Check with your xml & this attribute to the list android:choiceMode="multipleChoice" and see.
