android - 制作全屏视频 View

Question

我正在 android 中创建我的自定义视频播放器。我需要的要求是，当设备处于纵向模式时，VideoView 的高度是屏幕的一半，当我在横向模式下旋转设备时，它应该是全屏模式。但是我无法实现这个功能

下面是我的xml代码

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"

    }



    @Override
    public void onConfigurationChanged(Configuration newConfig) {
        super.onConfigurationChanged(newConfig);
        if(newConfig.orientation == Configuration.ORIENTATION_PORTRAIT){
             exitFullscreenVideo();
        }else if(newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE){
             fullScreenVideo();

        }
    }



}

据我了解，如果是这样的话，您希望布局在横向模式下全屏显示

在 layout-land 文件夹中为横向模式创建一个新布局

如果需要，请隐藏 ActionBar，然后在布局区域中使 VideoView match_parent 高度和宽度明智。

类似的东西

<VideoView 
    android:id="@+id/video"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>

更新:这并不完美，只是一个示例，向您展示如何保存视频位置，然后从那里继续播放

private VideoView myVideoView;
private int position = 0;

//THEN OVERRIDE THESE TWO METHODS TO SAVE THE VIDEOVIEW Position BEFORE ACTIVITY GETS RECREATED

@Override
    public void onSaveInstanceState(Bundle savedInstanceState) {
    super.onSaveInstanceState(savedInstanceState);

    //HERE WE ARE SAVING VideoView SATATE
    savedInstanceState.putInt("Position", myVideoView.getCurrentPosition());
    myVideoView.pause();
}


@Override
public void onRestoreInstanceState(Bundle savedInstanceState) {
    super.onRestoreInstanceState(savedInstanceState);

    //HERE WE GETTING THE Position BEFORE VIDEOVIEW WAS DESTROYED
    position = savedInstanceState.getInt("Position");
    myVideoView.seekTo(position);
}
