Question

在我的主要活动的应用程序中，我有一个设置为循环的媒体播放器变量。当我按下主页按钮时，音乐继续播放。我宁愿发生的是当用户点击主页按钮时关闭音乐。从我收集到的主页按钮无法被覆盖，我尝试onPause（）但是当我点击我的任何图像按钮时，音乐媒体播放器将停止。有没有解决这个问题？谢谢，如果您需要我的代码，请告诉我。

        //END OF BUTTON1 & SOUND



        }

    @Override

        if (keyCode == KeyEvent.KEYCODE_HOME) {
            mainSound.pause(); //stop media player
            return true;
        }
        return super.onKeyDown(keyCode, event);
    }




}

为什么不直接阅读主页按钮事件并暂停或停止媒体播放器？

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
    if (keyCode == KeyEvent.KEYCODE_HOME) {
        mediaPlayer.pause(); //stop media player
        return true;
    }
    return super.onKeyDown(keyCode, event);
}
