home和音量键监听的onKeyDown与onKeyUp使用 Android

public boolean onKeyDown(int keyCode, KeyEvent event) { if(keyCode==KeyEvent.KEYCODE_VOLUME_DOWN){ return true; } else if(keyCode==KeyEvent.KEYCODE_VOLUME_UP) { return true; }else { return super.onKeyDown(keyCode, event) }; }

【home和音量键监听的onKeyDown与onKeyUp使用】音量调节蔽掉了，唯独不能屏蔽掉调节音量的声音可以试试另一个
两个都可以起到监听作用

@Override public boolean onKeyUp(int keyCode, KeyEvent event) { if(keyCode==KeyEvent.KEYCODE_VOLUME_DOWN){ return true; }else if(keyCode==KeyEvent.KEYCODE_VOLUME_UP){ return true; }else { return super.onKeyUp(keyCode, event); } }

音量键调节 AudioManager audioManager= (AudioManager) getSystemService(Context.AUDIO_SERVICE); if (keyCode==KeyEvent.KEYCODE_VOLUME_UP){ audioManager.adjustStreamVolume(AudioManager.STREAM_MUSIC, AudioManager.ADJUST_RAISE,AudioManager.FX_FOCUS_NAVIGATION_UP); }if (keyCode==KeyEvent.KEYCODE_VOLUME_DOWN){ audioManager.adjustStreamVolume(AudioManager.STREAM_MUSIC, AudioManager.ADJUST_LOWER,AudioManager.FX_FOCUS_NAVIGATION_UP); }
