我有动画GIF图像的自定义ImageView。我想显示GIF图像,我试过,但在这种情况下,它包含在Async中的URL而不是我想显示原始文件夹中的GIF图像而不使用Glide。任何人都知道如何显示图像?请guyz帮助解决这个问题!!!
我试过这个设置原始文件
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;
}
}

我必须播放并暂停Gif图像Glide - Cannot stop gif onClick- Getting TransitionDrawable instead of Animate/GifDrawable
我的想法是从视图中获取drawable,检查它是否是Gifdrawable的实例并播放和暂停它。(希望gif图像已经播放)
在Onif of GifImageView中添加此内容
Drawable drawable = ((ImageView) v).getDrawable();
if (drawable instanceof GifDrawable) {
GifDrawable animatable = (GifDrawable) drawable;
if (animatable.isRunning()) {
animatable.stop();
} else {
animatable.start();
}
}

我使用GifMovieView !!!找到了上述问题的解决方案。
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());
}
}
