android play gif,Play.gif image in android without using webview

问题

I tried like this, which i found on the net to play gif images:

private class MYGIFView extends View {

Movie movie;

InputStream is = null;

long moviestart;

public MYGIFView(Context context) {

super(context);

// Provide your own gif animation file

is = context.getResources().openRawResource(R.drawable.mygif);

movie = Movie.decodeStream(is);

}

@Override

protected void onDraw(Canvas canvas) {

canvas.drawColor(Color.WHITE);

super.onDraw(canvas);

long now = android.os.SystemClock.uptimeMillis();

System.out.println("now=" + now);

if (moviestart == 0) { // first time

moviestart = now;

}

System.out.println("\tmoviestart=" + moviestart);

int relTime = (int) ((now - moviestart) % movie.duration());

System.out.println("time=" + relTime + "\treltime="

+ movie.duration());

movie.setTime(relTime);

movie.draw(canvas, this.getWidth() / 2 - 20,

this.getHeight() / 2 - 40);

this.invalidate();

}

Though many have said that they got their desired result.

I have put the gif image in drawable.

I am getting movie.duration() null.

Please suggest where am i wrong or if is there any way.

Android cannot play GIF files without WebView. You must break it apart into frames and animate it yourself.

I found on another StackOverflow post this bit of software from XoyoSoft, called GifSplitter, that can split a GIF into frames. You would then want to use AnimationDrawable to combine those.

It would look something like this:

// Your files:

res\drawable-xxxx\frame1.jpg

res\drawable-xxxx\frame2.jpg

res\drawable-xxxx\frame3.jpg

// ...

res\drawable-xxxx\frame99.jpg

Then, there is an example in the AnimationDrawable documentation above that will show how to display those images.

Lastly, you must load and play the animation; that, too, is detailed in the AnimationDrawable documentation.
