【思路】

• 1、自定义一个对话框去替换
• 2、使用旧版的对话框

这里我们选择最快的方法使用旧版对话框去显示

 public void showDialog(boolean keyguardShowing, boolean deviceProvisioned) 
        if (DEBUG) Slog.d(TAG, "showDialog " + keyguardShowing + " " + deviceProvisioned);
        if (mGlobalActionsProvider != null && mGlobalActionsProvider.isGlobalActionsDisabled()) 
            return;
        
        mKeyguardShowing = keyguardShowing;
        mDeviceProvisioned = deviceProvisioned;
        mShowing = true;
        if (mGlobalActionsAvailable && !"box".equals(SystemProperties.get("ro.target.product","unkonw"))) 
++ //            mHandler.postDelayed(mShowTimeout, 5000);
++ //            mGlobalActionsProvider.showGlobalActions();
++ //         else 
++            // SysUI isn't alive, show legacy menu.
            ensureLegacyCreated();
            mLegacyGlobalActions.showDialog(mKeyguardShowing, mDeviceProvisioned);
