android將文本設置爲textviews的arraylist

Question

如何設置文本到TextViews的數組。

這是我編：

public void onClickButtons(View view) { 

    if(view==mBtnGuess) { 
     int i; 
     String word = "someword"; 
     String getInput = mEtxtUserInput.getText().toString(); 
     char[] wordChars = word.toCharArray(); 
     if(getInput.length()>0) { 

      if(getInput.length()==1) { 
       List<TextView> txtCharArr= new ArrayList<TextView>(); 
       txtCharArr.add(mChar1); 
       txtCharArr.add(mChar2); 
       txtCharArr.add(mChar3); 
       txtCharArr.add(mChar4); 
       txtCharArr.add(mChar5); 
       txtCharArr.add(mChar6); 
       txtCharArr.add(mChar7); 
       txtCharArr.add(mChar8); 
       txtCharArr.add(mChar9); 
       txtCharArr.add(mChar10); 
       txtCharArr.add(mChar11); 
       txtCharArr.add(mChar12); 
       StringBuilder sb = new StringBuilder(); 
       for(i=0;i<wordChars.length;i++) { 
        if(wordChars[i]==(word.charAt(i))) { 
         txtCharArr.get(i).setText(word.charAt(i)); 
         sb.append(word.charAt(i)); 
        } 
       } 
      } 
     } 
    } 
} 

StringBuilder的僅僅是保存在那裏等於所有字符。上面的代碼提供了一個錯誤：

行232：

txtCharArr.get(i).setText(word.charAt(i)); 

我也試過：

public void onClickButtons(View view) { 

     if(view==mBtnGuess) { 
      int i; 
      String word = "someword"; 
      String getInput = mEtxtUserInput.getText().toString(); 
      if(getInput.length()>0) { 

       if(getInput.length()==1) { 
        List<TextView> txtCharArr= new ArrayList<TextView>(); 
        txtCharArr.add(mChar1); 
        txtCharArr.add(mChar2); 
        txtCharArr.add(mChar3); 
        txtCharArr.add(mChar4); 
        txtCharArr.add(mChar5); 
        txtCharArr.add(mChar6); 
        txtCharArr.add(mChar7); 
        txtCharArr.add(mChar8); 
        txtCharArr.add(mChar9); 
        txtCharArr.add(mChar10); 
        txtCharArr.add(mChar11); 
        txtCharArr.add(mChar12); 
        StringBuilder sb = new StringBuilder(); 
        for(i=0;i<getInput.length();i++) { 
         if(getInput.equals(word.charAt(i))) { 
          txtCharArr.get(i).setText(word.charAt(i)); 
          sb.append(word.charAt(i)); 
         } 
        } 
       } 
      } 
     } 
    } 

但這並不顯示任何東西。 StringBuilder是空的，當我輸入一個應該匹配的字符時，textViews中沒有顯示字符。

Answer 1

因爲沒有TextView.setText(char x)，所以您的char被轉換爲int，調用TextView.setText(int x)，它將搜索ID爲x的資源。

您應該將一個字符串傳遞給setText()方法。您可以嘗試

txtCharArr.get(i).setText(Character.toString(word.charAt(i)));

或

txtCharArr.get(i).setText(word.subString(i, i+1)));
