Question

我有一个按钮，当按下该按钮时，它会播放从Firebase存储中获取的mp3文件，问题是如果我按两次按钮，音频会重叠。再次按下按钮时如何使音频暂停？很抱歉，如果以前回答过这个问题，但我是新来的，如果不是我个人的情况，我很难理解。

 button2=findViewById(R.id.button2);
        button2.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                try {
                    MediaPlayer player = new MediaPlayer();
                    player.setAudioStreamType(AudioManager.STREAM_MUSIC);
                    player.setDataSource("https://firebasestorage.googleapis.com/v0/b/yovoicest2.appspot.com/o/songs%2FDeath.mp3?alt=media&token=925d52c3-e5a7-4b2c-a598-e83a97730a24");
                    player.prepare();
                    player.start();
                } catch (Exception e) {
                    // TODO: handle exception
                }
            }
        });```

将Media Player定义为Member变量并检查。

MediaPlayer player = new MediaPlayer();
button2=findViewById(R.id.button2);
button2.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        if(player != null && player.isPlaying()) {
            // Handle the playing like changing the button Text/Image
            player.stop();
        } else {
            // Handle the stop like changing the button Text/Image
            //Do your thing. Initialize it again with whatever file you want.
        }
    }
});
