所有内容都可以正常播放，就像流媒体视频一样，但是我无法使此VideoView转到 landscape 并在 fullscreen 中显示视频.我曾尝试使用Google搜索，但目前发现的所有示例对我来说都不起作用.因此，请告诉我如何切换全屏.
谢谢.
Everything is working fine like streaming videos and all but I am unable to make this VideoView to go to landscape and show the video in fullscreen. I have tried googling it but all the examples I have found are not working for me at the moment. So please tell me how it is possible to toggle fullscreen.
Thanks.
推荐答案
我所做的是创建了一个CustomVideoView，它扩展了VideoView，如下所示:
What i have done is that i created a CustomVideoView which extends VideoView like this:
public class CustomVideoView extends VideoView {
private int measuredWidth = 0;
private int measuredHeight = 0;
public CustomVideoView(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
// TODO Auto-generated constructor stub
}
public CustomVideoView(Context context, AttributeSet attrs) {
super(context, attrs);
// TODO Auto-generated constructor stub
}
public CustomVideoView(Context context) {
super(context);
// TODO Auto-generated constructor stub
}
public void setNewDimension(int width, int height) {
this.measuredHeight = height;
this.measuredWidth = width;
}
@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
// TODO Auto-generated method stub
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
setMeasuredDimension(measuredWidth, measuredHeight);
}
}//end class
然后在播放器活动中，我在全屏按钮的onclick上实现了此操作:
Then on my player activity, i implemented this on fullscreen button's onclick:
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
DisplayMetrics metrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(metrics);
android.widget.RelativeLayout.LayoutParams params = new android.widget.RelativeLayout.LayoutParams(
android.widget.RelativeLayout.LayoutParams.MATCH_PARENT,
android.widget.RelativeLayout.LayoutParams.MATCH_PARENT);
player.setNewDimension(metrics.widthPixels, metrics.heightPixels);
player.getHolder().setFixedSize(metrics.heightPixels,
metrics.widthPixels);
player.setLayoutParams(params);
因此，我的问题得以解决.希望它也能解决其他问题.
so with this my problem was solved. Hope it will solve others problem as well.
注意:很抱歉，我没有给任何人任何积分，因为我忘记了我在google上找到的链接，这些链接使我为自己找到合适的解决方案.
NOTE: I'm sorry for not giving anybody credits as i forgot the links i found on google which lead me to make a suitable solution for myself.
