Set GIF image to Custom ImageView

问题

I have custom ImageView for animated GIF image. i want to show GIF image, I tried but in this case it is contain url in Async instead I want to show GIF image from raw folder without using Glide. Anyone have any idea how to show image? Please guyz help to solve this problem!!!

I tried this for set raw file

 new GifStaticData() {
            @Override
            protected void onPostExecute(Resource drawable) {
                super.onPostExecute(drawable);
                gifImageView.setImageResource(R.raw.earth_tilt_animation);
//                Log.d(TAG, "GIF width is " + gifImageView.getGifWidth());
               // Log.d(TAG, "GIF height is " + gifImageView.getGifHeight());
            }

        }.execute(R.raw.earth_tilt_animation);

GifStaticData.java

public class GifStaticData extends AsyncTask<Resource, Void, Resource> {
  private static final String TAG = "GifDataDownloader";

  @Override protected Resource doInBackground(final Resource... params) {
    final Resource gifUrl = params[0];

    if (gifUrl == null)
      return null;

    try {
//      return ByteArrayHttpClient.get(gifUrl);
      return gifUrl;
    } catch (OutOfMemoryError e) {
      Log.e(TAG, "GifDecode OOM: " + gifUrl, e);
      return null;
    }
  }
}

I had to play and pause the Gif image Glide - Cannot stop gif onClick- Getting TransitionDrawable instead of Animate/GifDrawable

The idea is to get drawable from view,checking if it is an instance of Gifdrawable and playing and pausing it.(Hoping the gif image is already playing)

Add this In OnClick of GifImageView

Drawable drawable = ((ImageView) v).getDrawable();
if (drawable instanceof GifDrawable) {
         GifDrawable animatable = (GifDrawable) drawable;
         if (animatable.isRunning()) {
                 animatable.stop();
         } else {
                animatable.start();
         }
}

I found the solution of above problem using GifMovieView!!!

GifMovieViewer.java

public class GifMovieViewer extends Activity {
    private Button btnStart;
    private GifMovieView gif1;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.gif_movie_viewer);

        gif1 = (GifMovieView) findViewById(R.id.gif1);
        btnStart = (Button) findViewById(R.id.btnStart);

        btnStart.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                gif1.setMovieResource(R.drawable.earth_tilt_animation);
                //for pause
                // gif1.setPaused(gif1.isPaused());
            }
        });
    }

    public void onGifClick(View v) {
        GifMovieView gif = (GifMovieView) v;
        gif.setPaused(!gif.isPaused());
    }
}
