android - 在全屏视频上添加全屏按钮

Question

我需要添加功能以全屏观看视频。

Videoview的控制面板上是否仅提供3个按钮（<<）（>）（>>），因为它可以添加第四个按钮以全屏显示视频？

要全屏观看视频，只需将嵌入视频的布局参数更改为fill_parent。

有任何想法吗？

谢谢

最后，我通过将按钮手动添加到“相对布局”中来解决了该问题：

LinearLayout lLinLayout = new LinearLayout(this);
lLinLayout.setId(1);
lLinLayout.setOrientation(LinearLayout.VERTICAL);
lLinLayout.setGravity(Gravity.CENTER);
lLinLayout.setBackgroundColor(Color.BLACK);

LayoutParams lLinLayoutParms = new LayoutParams(ViewGroup.LayoutParams.FILL_PARENT,
     ViewGroup.LayoutParams.FILL_PARENT);
lLinLayout.setLayoutParams(lLinLayoutParms);

this.setContentView(lLinLayout);


RelativeLayout lRelLayout = new RelativeLayout(this);
lRelLayout.setId(2);
lRelLayout.setGravity(Gravity.CENTER);
lRelLayout.setBackgroundColor(Color.BLACK);
android.widget.RelativeLayout.LayoutParams lRelLayoutParms = 
    new android.widget.RelativeLayout.LayoutParams(ViewGroup.LayoutParams.FILL_PARENT,
       ViewGroup.LayoutParams.FILL_PARENT);
lRelLayout.setLayoutParams(lRelLayoutParms);
lLinLayout.addView(lRelLayout);

mVideoView = new VideoView(this);
mVideoView.setId(3);
android.widget.RelativeLayout.LayoutParams lVidViewLayoutParams =
  new android.widget.RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT,
     ViewGroup.LayoutParams.WRAP_CONTENT);
lVidViewLayoutParams.addRule(RelativeLayout.CENTER_IN_PARENT);
mVideoView.setLayoutParams(lVidViewLayoutParams);
lRelLayout.addView(mVideoView);

Button myButton = new Button(this);
myButton.setId(3);
android.widget.RelativeLayout.LayoutParams buttonParams =
   new android.widget.RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT,
     ViewGroup.LayoutParams.WRAP_CONTENT);
buttonParams.addRule(RelativeLayout.CENTER_IN_PARENT);
myButton.setLayoutParams(buttonParams);
myButton.setText("My Button!");
lRelLayout.addView(myButton);
