android调整视频方向,android – 调整视频大小

我正在尝试动态设置

Android VideoView的大小.我看过StackOverflow以及互联网;我找到的最佳解决方案是从

here开始.我已经将我的实现放在下面：

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...");

}

}

视频在Android模拟器和Motorola Droid X上正确调整大小;但在摩托罗拉Droid上,VideoView会调整大小,但VideoView中播放的视频不会调整大小.在摩托罗拉Droid上,如果VideoView设置为比视频播放更大的尺寸,VideoView中会出现黑色背景,视频在VideoView的左上角播放在黑色背景的顶部.

如何在Android中正确调整VideoView的大小？

谢谢,
