例如,我想播放3首歌曲。当第一首歌曲结束时,第二首歌曲开始,第二首歌曲结束,第三首歌曲开始,第三首歌曲结束,第一首歌曲再次开始,依此类推。这里使用了{{1}}吗?

你是对的。你可以做这样简单的事情:
public class MainActivity extends Activity {
MediaPlayer mp1, mp2, mp3;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mp1 = MediaPlayer.create(this, R.raw.music_1);
mp2 = MediaPlayer.create(this, R.raw.music_2);
mp3 = MediaPlayer.create(this, R.raw.music_3);
mp1.start();
mp1.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
@Override
public void onCompletion(MediaPlayer mp) {
mp2.start();
}
});
mp2.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
@Override
public void onCompletion(MediaPlayer mp) {
mp3.start();
}
});
mp3.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
@Override
public void onCompletion(MediaPlayer mp) {
mp1.start();
}
});
}
}
这将播放mp1和onCompletion它,它将播放mp2,并且onmpmpletion为mp2,它将播放mp3,并且onCompletion of mp3,它将再次播放mp1等等...

首先声明3个MediaPlayer文件:
MediaPlayer song1;
MediaPlayer song2;
MediaPlayer song3;
然后初始化MediaPlayer
个对象:
song1 = MediaPlayer.create(this, R.raw.exampleSong1);
song2 = MediaPlayer.create(this, R.raw.exampleSong2);
song3 = MediaPlayer.create(this, R.raw.exampleSong3);
现在使用
启动第一个媒体文件song1.start();
现在,每创建一个实例,您应该像这样添加MediaPlayer
个setOnCompletionListener
对象:
song1.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
@Override
public void onCompletion(MediaPlayer mp) {
song2.start();
}
});
对第二个和第三个MediaPlayer文件执行相同的操作:
song2.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
@Override
public void onCompletion(MediaPlayer mp) {
song3.start();
}
});
song3.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
@Override
public void onCompletion(MediaPlayer mp) {
song1.start();
}
});
