HOME：

@Override
public 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);
