问题描述

我想借此overinput在音量上下。此刻我的code是:

  @覆盖
公共布尔的onkeydown(INT键code,KeyEvent的事件){

    Log.v(TAG,event.toString());
    如果(键code == KeyEvent.KEY code_VOLUME_DOWN){
        mLamp.moveBackward();

        返回false;
    }
    否则,如果(键code == KeyEvent.KEY code_VOLUME_UP){
        mLamp.moveFor​​ward();

        返回false;
    }

    返回true;
}
公共布尔的onkeyup(INT键code,KeyEvent的事件){

    Log.v(TAG,event.toString());
    如果(键code == KeyEvent.KEY code_VOLUME_DOWN){
        返回false;
    }
    否则,如果(键code == KeyEvent.KEY code_VOLUME_UP){
        返回false;
    }

    返回true;
}
 

这会触发 mLamp.moveBackward() mLamp.moveFor​​ward()的功能,但它仍然改变音量的铃声。我有什么做的铃声音量不改?

解决方案

I want to take overinput over the Volume Up and Down. At the moment my code is:

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {

    Log.v(TAG, event.toString());
    if (keyCode == KeyEvent.KEYCODE_VOLUME_DOWN){
        mLamp.moveBackward();

        return false;
    }
    else if(keyCode == KeyEvent.KEYCODE_VOLUME_UP){
        mLamp.moveForward();

        return false;
    }

    return true;
}
public boolean onKeyUp(int keyCode, KeyEvent event) {

    Log.v(TAG, event.toString());
    if (keyCode == KeyEvent.KEYCODE_VOLUME_DOWN){
        return false;
    }
    else if(keyCode == KeyEvent.KEYCODE_VOLUME_UP){
        return false;
    }

    return true;
}

This triggers the mLamp.moveBackward() and mLamp.moveForward() function but it still changes the volume of the ringer.What do I have to do that the ringer loudness doesn't change?
