推荐答案

仅创建一个Button并添加诸如buttonstatus之类的内容.然后，您可以在侦听器中检查状态.
例如:

Create just one Button and add something like a buttonstatus. Then you can check the status in your listener.
For example:

boolean isPlaying = false;
playPause = (Button) findViewById(R.id.play);


 playPause.setOnClickListener(new View.OnClickListener() {
   public void onClick(View view) {
   if (isPlaying) {
     pause();
   }else{
     play();
   }
   isPlaying = !isPlaying;
}
});
