VideoView播放循环中的多个视频吗？

Question

我已经在视频视图中成功播放了一个视频。 现在我想在循环中播放2个或更多视频。 视频从服务器下载并保存在SD卡中，我想从那里玩。

下面的代码正在工作，但问题是只有第一个视频播放循环。 我想一个接一个地播放所有3个视频。

Answer 1

你需要增加你的videoIncrementer如果要播放下一个视频。

@Override 
public void onCompletion(MediaPlayer mp) { 
    try { 
    mp.stop(); 
    mp.reset(); 
    // Add this line 
    videoIncrementer = ++videoIncrementer < tempPath.length ? videoIncrementer : 0; 
    mp.setDataSource(tempPath[videoIncrementer]); 
    mp.prepare(); 
    mp.start(); 
    } catch (IOException e) { 
     e.printStackTrace(); 
    } 

} 

++videoIncrementer→递增变量

< tempPath.length→检查递增videoIncrement处于tempPath阵列的边界。如果是，则videoIncrementer设置为videoIncrementer，否则重置为0;
