MediaPlayer.create() 总是返回 null

问题描述

我以前用过媒体播放器，从来没有遇到过这个问题.每当我尝试使用 MediaPlayer.create() 时，该方法都会给我空值，并且我无法播放我的声音.有什么我遗漏的吗?

I have used the mediaplayer before, and I have never had this problem. Whenever I try to use MediaPlayer.create(), the method gives me null, and I can't play my sounds. Is there anything that I am missing?

public class Game extends Activity
{
    private MediaPlayer mp = null;

    @Override
    protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.game);

        mp = MediaPlayer.create(getBaseContext(), R.raw.sound);
    }
}

我的 sound.mp3 位于我的原始文件夹中，我通过将我的声音拖动到 eclipse 中的文件夹来放置在那里.请帮忙，因为我以前玩过声音，这真的让我很烦恼:(

my sound.mp3 is in my raw folder, which I placed in there by draging my sound to the folder in eclipse. Please help, since I have played sound before, this is really bugging me :(

推荐答案

create() API 返回 null 如果它以某种方式失败.

The create() API returns null if it somehow failed.

这种情况下的原因是 mp3 文件损坏.

The reason in this case is due to a corrupt mp3 file.
