android在內部類運行時沒有得到editText值

Question

我有一定的問題。我正在創建一個帶有自定義tableLayout作爲消耗列表子項的消耗性列表。 Table Layput在每行中有1個textView和3個EditText。

現在，問題在於TableLayout中的editTexts沒有檢測到運行時輸入的文本。它從editText中給出空白值。請找到附件中的代碼並提出解決問題的建議。

主要問題在於gettabledata（）中的editText方法顯示isInEditMode「False」。您可以請幫助我們如何在運行時將IsInEditMode設置爲「true」。

Answer 1

實際上，通過在初始化EditText時將getTextData（）方法設置爲getChildView（）中的每個EditText上的TextWatcher解決了問題，並且每次都在其他變量中存儲輸入到edittext中的數據。因爲getChildView（）會在單擊每個editText時重新加載。因此，editText值需要存儲在任何其他變量中，以檢索後續數據。

例如：

@覆蓋公共無效beforeTextChanged（CharSequence中，整數 開始，詮釋計數，INT後）{// TODO自動生成方法存根 }

    public void afterTextChanged(Editable s) { // TODO 
         if((s!=null&&s.length()>0)){ 

         v2 = s.toString(); 
         Pattern p = Pattern.compile("([0-9]*)"); 

         Matcher m = p.matcher(v2); 
          System.out.println("v2 :::::" + v2); 

          if(stateCount>=States.length) 
           stateCount =0; 

           else 

           stateCount = stateCount+1; 
          System.out.println("SateCount in v2:::::::::::::::" + stateCount); 
           insertInV2Array(stateCount,v2); 


         if(!m.matches()) 
         { 

           Toast.makeText(VarietyDetailsActivity.this, "Please enter between 1- 9 only",8) 
           .show(); 



         } 


         } 

Answer 2

將設置在每一個的EditText時TextWatcher在EDITTEXT文本已經被改變了就會被調用。
