android - MediaPlayer.release()后SurfaceView是否可以复用？

Question

假设我们有以下内容(来自 Android ApiDemos):

<?xml version="1.0" encoding="utf-8"?>

<SurfaceView android:id="@+id/surface"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center">
</SurfaceView>

MediaPlayer使用SurfaceView后，调用release()，SurfaceView是否可以复用？我试图创建一个新的 MediaPlayer 实例来重用 SurfaceView，但是在 setDisplay() 时出现以下错误: java.lang.IllegalArgumentException: 表面已释放

代码如下:

    mPreview = (SurfaceView) findViewById(R.id.surface);
holder = mPreview.getHolder();
holder.addCallback(this);

mMediaPlayer = new MediaPlayer();
MediaPlayer.setDataSource(url);

mMediaPlayer.setDisplay(holder);

Answer 1

试试这个:

    @Override
public void surfaceCreated(SurfaceHolder holder) {
    System.out.println("===== * surfaceCreated * =====");
    if(mMediaPlayer == null)
        mMediaPlayer = new MediaPlayer();
    mMediaPlayer .setDisplay(holder);
}
