you can get repeat state from your mediaPlayer 您可以从mediaPlayer获得重复状态
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
}
}
});
note that setLooping just set repeat mode for your media player so if your x (media player) is not playing you can also set x.start() or x.resume() base on your player state. 请注意， setLooping只是为媒体播放器设置重复模式，因此，如果您的x（媒体播放器）未播放，您还可以根据播放器状态设置x.start()或x.resume() 。

You might find your answer in this post: How set background drawable programmatically in Android 您可能会在这篇文章中找到答案： 如何在Android中以编程方式设置背景可绘制
As you are dealing with button, check out this this interesting link : https://developer.android.com/reference/android/widget/Button.html 在处理按钮时，请查看以下有趣的链接： https : //developer.android.com/reference/android/widget/Button.html
In order to detect when the background changes. 为了检测背景何时变化。 I advise you to implementing a class which extends MediaPlayer and use it. 我建议您实现一个扩展MediaPlayer的类并使用它。 You should implement an public interface iinside your activity in order to observe the change of backgrounds. 您应该在活动中实现一个公共界面，以便观察背景的变化。
