設置窗口小部件的可見性，當兩個窗口小部件高於另一個時

我需要創建一個如下所示的片段。設置窗口小部件的可見性，當兩個窗口小部件高於另一個時

點擊Need Cash TextView將改變含佈局這將有兩個按鈕Cancel & Meet和這些視圖之間切換英寸

但是當我點擊需要現金呼叫toggleVisibility()功能使Need Cash隱形但不顯示Cancel | Meet。

我在這個過程中犯了什麼錯誤？

EDIT

public View onCreateView(LayoutInflater inflater, ViewGroup container, 
          Bundle savedInstanceState) { 
     // Inflate the layout for this fragment 
     View thisView = inflater.inflate(R.layout.fragment_map, container, false); 
return thisView; 
}

EDIT點擊之前2

片段視圖，其示出了保持現金的TextView

0點擊後

片段視圖，其沒有顯示 '取消' 和 '滿足' TextViews

**編輯3 ** 指定ID到外RelativeLayout的和無效的它

public void toggleVisibility() { 
     if(needCashTv.getVisibility() == View.VISIBLE) { 
      //needCashTv.setEnabled(false); 
      needCashTv.setVisibility(View.GONE); 

      frameForNeedCashStuff.setVisibility(View.VISIBLE); 
      //cancelNeedCashTv.setEnabled(true); 
      cancelNeedCashTv.setVisibility(View.VISIBLE); 
      //letsMeetneedCashTv.setEnabled(true); 
      letsMeetneedCashTv.setVisibility(View.VISIBLE); 
      frameForNeedCashStuff.bringToFront(); 
     } 
     else { 
      //needCashTv.setEnabled(true); 
      needCashTv.setVisibility(View.VISIBLE); 
      needCashTv.bringToFront(); 

      frameForNeedCashStuff.setVisibility(View.GONE); 
      //cancelNeedCashTv.setEnabled(false); 
      cancelNeedCashTv.setVisibility(View.GONE); 
      //letsMeetneedCashTv.setEnabled(false); 
      letsMeetneedCashTv.setVisibility(View.GONE); 
     } 
     ((ViewGroup)frameForNeedCashStuff2.getParent()).invalidate(); 
     //thisView.invalidate(); 
    }

修復後的工作代碼 編輯4

你可以嘗試使父視圖無效而不是實際視圖。（（ViewGroup）getParent（））。invalidate（）; –

@bastienpinaquy您可以確認其父視圖，佈局或小工具。 – dearvivekkumar

嘗試此 '（（ViewGroup）frameForNeedCashStuff.getParent（））。invalidate（）;'但仍面臨同樣的問題。 – dearvivekkumar

你RelativeLayout包裹TextView S（tv_need_cash_cancel和tv_need_cash_lets_meet設置爲 '走了'。

如果您只是切換子視圖的可見性，它將不會顯示。您是否確定需要View.invalidate()？如果您只是切換可視性，則沒有必要。

調用thisView.invalidate（）; – dearvivekkumar

此視圖實際上是由inflater返回的視圖引用 – dearvivekkumar

您是否檢查過它實際上爲您做了什麼？我真的不認爲這是必要的。你是否按照我的建議設置「RelativeLayout」爲可見狀態？ –
