你怎么防止它在android中运行不止一次的声音？

Question

当我点击按钮操作歌曲时，按下它再次操作互操作 如果再次按下再次启动声音，我怎么能不重叠？

public class Circal extends Activity {

    Button sound = (Button) findViewById(R.id.sound);
    sound.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            MediaPlayer player = MediaPlayer.create(Circal.this,R.raw.one);
            player.start();
        }
    });
}

如果条件已经开始，则添加if条件

if(player.isPlaying()){
    player.pause(); // pause before doing anything
    player.seekTo(0); // go to 0 seconds
}
player.start()
