Baseadapter的getView（）顯示不相關的信息

我有兩個gridviews。（名字是我給）Baseadapter的getView（）顯示不相關的信息

熱門的GridView：有的像「123456123456」
底部的GridView號：含有數字0 - 9

最初在GridView的所有項目將是空的（像不可見的東西）。根據底部網格視圖中的項目點擊，將顯示頂部網格視圖中的項目。例如：

例如：假設top gridview中的項是「123456123456」。最初都是看不見的。一旦我點擊底部網格視圖中的項目，我需要在頂部網格視圖中顯示適當的數字。可以說，我點擊了1.網格視圖項目，我有「1」應該是可見的。

我試過這個邏輯，但出了點問題，最後我得到了一些奇怪的結果。

查看輸出：

如果您看到輸入上面的圖像「123456123456」，當被點擊1全1都變成可見的。當我點擊2，2的可見，甚至額外的1被分配給網格。我不知道爲什麼會發生這種情況。

這是我試過的代碼。

主要活動：

public class MainActivity extends Activity { 
GridView grid_topNumbers; 
GridView gridview_belownumbers; 
@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 

    gridview_belownumbers = (GridView)findViewById(R.id.gridview_belownumbers); 
    grid_topNumbers = (GridView)findViewById(R.id.gridview_topnumbers); 

    TopGrid topGridAdapter = new TopGrid(this); 

    Constants.topNumbers = "123456123456"; 


    List<TopNumbersObject> topNumList = new ArrayList<TopNumbersObject>(); 
    TopNumbersObject topnumObj = null; 

    for(int i=0;i< Constants.topNumbers.length();i++){ 
     topnumObj = new TopNumbersObject(); 
    if(i<Constants.topNumbers.length()-1) 
    { 
     topnumObj.number = (Constants.topNumbers.substring(i, i+1))+""; 
    } 
    else 
    { 
     topnumObj.number = (Constants.topNumbers.substring(i))+""; 
    } 
    topnumObj.isVisited =false; 
    topNumList.add(topnumObj); 
    } 

    Constants.TopNumbersList = topNumList; 

    grid_topNumbers.setAdapter(topGridAdapter); 
    gridview_belownumbers.setAdapter(new CustomGridViewAdapter(this,topGridAdapter)); 
} 

@Override 
public boolean onCreateOptionsMenu(Menu menu) { 
    getMenuInflater().inflate(R.menu.activity_main, menu); 

    return true; 
} 
}

public CustomGridViewAdapter(Context c,TopGrid topAdapter) { 
    params = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, 
      LayoutParams.WRAP_CONTENT); 
    cont = c; 
    this.topAdapter = topAdapter; 

    // type = Typeface.createFromAsset(cont.getAssets(),

     tv.setText(arg0+""); 

     tv.setOnClickListener(new OnClickListener() { 

      @Override 
      public void onClick(View arg0) { 

       TextView clickedTextView = (TextView)arg0; 
       String letter = clickedTextView.getText().toString(); 

       for(int i=0;i<Constants.topNumbers.length();i++) 
       { 
        TopNumbersObject letterObject = Constants.TopNumbersList.get(i);

         letterObject.isVisited = true; 
         if(Constants.topNumbers.toLowerCase().lastIndexOf(letter.toLowerCase()) == i) 
         { 
          topAdapter.notifyDataSetChanged(); 
          break; 
         } 
        } 


       } 

       clickedTextView.setClickable(false); 
       clickedTextView.setOnClickListener(null); 
      } 

     }); 


    return v;

任何人都可以建議我哪裏出了錯。

在我需要時管理更改topgrid項目的可見性。

取而代之的是

if(topnoObject.isVisited) 
{ 
    h.tv.setText(topnoObject.number); 
}

用下面的代碼。

if(topnoObject.isVisited) 
{ 
    h.tv.setVisibility(View.VISIBLE); 
} 
else 
{ 
    h.tv.setVisibility(View.INVISIBLE); 
} 
h.tv.setText(topnoObject.number);

但仍在等待更準確的答案
