android屏蔽BACK键、HOME键和多任务键

HOME：

@Overridepublic void onAttachedToWindow() {    System.out.println("Page01 -->onAttachedToWindow");    this.getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD_DIALOG);    super.onAttachedToWindow();}

BACK键：

@Override    public void onBackPressed() {//        super.onBackPressed();    }

多任务键：

getWindow().addFlags(5);
