java - 使用WindowManager添加 View 时如何处理所有按键事件？

Question

问题出在服务 View 后退按钮给了我响应，但主页和最近的应用程序按钮没有触发

@Override
public boolean onKey(View v, int keyCode, KeyEvent event) {
    switch (keyCode) {
        case KeyEvent.KEYCODE_HOME: //Not getting
            minimizeApp();
            return true;

        case KeyEvent.KEYCODE_BACK: //getting
            finish(false);
            return true;

        case KeyEvent.KEYCODE_APP_SWITCH: //Not getting
            //minimizeApp();
            return true;
    }
    return true;
}

在同一服务中，我尝试添加和删除不同的标志，但无法得到我想要的。

mLayoutParams =new WindowManager.LayoutParams(
                    WindowManager.LayoutParams.MATCH_PARENT,
                    WindowManager.LayoutParams.MATCH_PARENT,
                    WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY,
                    WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL|
                    WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN| 
                    WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON| 
                    WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON
                    |WindowManager.LayoutParams.TYPE_SYSTEM_ALERT
                    |WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED
                    ,
                    PixelFormat.TRANSLUCENT);

我按下“后退”键，但我想捕获按下主页和最近应用程序的事件。

已更新我得到了解决方案

  li = LayoutInflater.from(this);
       LinearLayout lia=  new LinearLayout(this) {

            //home or recent button
            public void onCloseSystemDialogs(String reason) {

                if (reason.equals("homekey")){
                    finisha(false);
                }
                if (reason.equals("recentapps")){
                    finisha(false);

                }

            }

            @Override
            public boolean dispatchKeyEvent(KeyEvent event) {
                if (event.getKeyCode() == KeyEvent.KEYCODE_BACK
                        || event.getKeyCode() == KeyEvent.KEYCODE_APP_SWITCH
                        || event.getKeyCode() == KeyEvent.KEYCODE_HOME
                     ) {

                    //The Code Want to Perform.
               //     return true;
                }
                if (event.getKeyCode() == KeyEvent.KEYCODE_HOME){

                }

                if (event.getKeyCode() == KeyEvent.KEYCODE_APP_SWITCH){

                }
                return super.dispatchKeyEvent(event);
            }
        };

        lia.setFocusable(true);

        final View root = (View) li.inflate(R.layout.layout_alias_locker, lia);
