您可以从mediaPlayer获取重复状态
repeat.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if(x != null ){
if ( x.isLooping()) {
//player is in repeat mode , so turn it off and change repeat buttun background to normal
repeat.setBackgroundResource(R.drawable.repeat_off);
x.setLooping(false);
}else {
//player isn't in repeat mode , so turn it on and change repeat buttun background to repeating image
repeat.setBackgroundResource(R.drawable.repeat_on);
x.setLooping(true);
}
}else {
//player is null
}
}
});
请注意，
setLoopingx.start（）x.resume（）以便检测背景何时变化。我建议您实现一个扩展MediaPlayer的类并使用它。为了观察背景的变化，你应该在你的活动中实现一个公共界面 但是，当背景发生变化时，如何使歌曲重复？
