Resize VideoView

Question

I am attempting to dynamically set the size of an Android VideoView. I have looked on StackOverflow as well as the internet; and the best solution I found was from here. I have put my implementation below: ``` public class ResizableVideoView extends VideoView { public ResizableVideoView(Context c) { super(c); } private int mVideoWidth = 100; private int mVideoHeight = 100; public void changeVideoSize(int width, int height) { mVideoWidth = width; mVideoHeight = height; // not sure whether it is useful or not but safe to do so getHolder().setFixedSize(width, height); forceLayout(); invalidate(); // very important, so that onMeasure will be triggered } public void onMeasure(int specwidth, int specheight) { Log.i("onMeasure","On Measure has been called"); setMeasuredDimension(mVideoWidth, mVideoHeight); } public void onDraw(Canvas c) { super.onDraw(c); Log.i("onDraw","Drawing..."); } } ``` The video resizes correctly on the Android emulator as well as on a Motorola Droid X; but on a Motor…

Accepted Answer

My implementation works like this:

```
RelativeLayout.LayoutParams videoviewlp = new RelativeLayout.LayoutParams(newwidth, newheight);
    videoviewlp.addRule(RelativeLayout.CENTER_HORIZONTAL, RelativeLayout.TRUE);
    videoviewlp.addRule(RelativeLayout.CENTER_VERTICAL, RelativeLayout.TRUE);
    videoview.setLayoutParams(videoviewlp);
    videoview.invalidate();
```

By invalidating the videoview, you will force it to redraw the whole videoview using the new LayoutParams (and the new dimensions).
