android屏蔽返回键和home键

  1. 屏蔽返回键的代码:
    public boolean onKeyDown(int keyCode,KeyEvent event){
    switch(keyCode){
    case KeyEvent.KEYCODE_HOME:return true;
    case KeyEvent.KEYCODE_BACK:return true;
    case KeyEvent.KEYCODE_CALL:return true;
    case KeyEvent.KEYCODE_SYM: return true;
    case KeyEvent.KEYCODE_VOLUME_DOWN: return true;
    case KeyEvent.KEYCODE_VOLUME_UP: return true;
    case KeyEvent.KEYCODE_STAR: return true;
    }
    return super.onKeyDown(keyCode, event);
    }

    屏蔽home键的代码:
    public void onAttachedToWindow() {
    this.getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD);
    super.onAttachedToWindow();
    }
