如何使用VideoView Android切换FullScreen

Question

我正在使用视频视频进行实时流媒体播放,我希望将其设置VideoView为全屏切换并返回小屏幕,MXPlayer或者YouTube播放器不停止流.

<ScrollView

一切都很好,像流媒体视频和所有,但我无法使这个VideoView去景观和全屏显示视频.我试过谷歌搜索它,但我发现的所有例子目前都不适合我.所以请告诉我如何切换全屏幕.谢谢.

Answer 1

我所做的是我创建了一个 CustomVideoView，它像这样扩展了 VideoView：

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

然后在我的播放器活动中，我在全屏按钮的 onclick 上实现了这个：

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);

这样我的问题就解决了。希望它也能解决其他问题。
