Question

我在视频视频中成功播放了一个视频。现在我想循环播放2个或更多视频。视频从服务器下载并保存在SD卡中，我想从那里播放。

下面的代码正在运行，但问题是只有第一个视频在循环播放。我希望一个接一个地播放所有3个视频。

我的代码

如果您想要播放下一个视频，则需要增加videoIncrementer。

    @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→增加变量

< tempPath.length→检查递增的videoIncrement是否在tempPath数组的范围内。如果是，videoIncrementer设置为videoIncrementer，否则重置为0;

VideoView是否在循环中播放多个视频？
