無法在item click on listener上獲取gridView

Question

我無法在片段中獲取gridView的setOnItemClickListener。可能是什麼問題？

這裏是我的代碼::

public class MainMenuFragment extends Fragment { 

    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 
    // Inflate the layout for this fragment 

     View view = inflater.inflate(R.layout.main_menu_fragment, container, false); 

     itemsGridViewObj = (GridView) view.findViewById(R.id.itemsGridView); 



     itemsGridViewObj.setOnItemClickListener(new OnItemClickListener() { 

      @Override 
      public void onItemClick(AdapterView<?> arg0, View arg1, int position, 
        long arg3) { 

       Log.d(TAG, "--> onItemClick listener...");  // Can not getting this method. 
       /*if(position == 1) { 
        FruitMenuFragment fruitMenuFragment = new FruitMenuFragment(); 
        fragmentTransaction.replace(android.R.id.content, fruitMenuFragment); 
        fragmentTransaction.commit(); 
       }*/ 
      } 
     }); 

     return view; 
    } 
}` 

Answer 1

您可能需要設置您的ButtonView以下。 機器人：可調焦= 「假」 機器人：focusableInTouchMode = 「假」

看到adding CheckBox to list row loses my onItemClick events?

Answer 2

當使用片段發生在兩個階段的觀點的初始化。

該視圖僅在onCreateView方法之後被誇大（因此可訪問）。此方法僅用於使視圖膨脹並將其返回到碎片。

因此，任何關於查找視圖和設置onClickListeners的邏輯都應在onActivityCreated（）函數中完成，因爲這是您可以訪問充氣視圖的第一個點。

看一看谷歌的文檔在http://developer.android.com/reference/android/app/Fragment.html#Lifecycle

下面是你的代碼調整以符合什麼事情讓我上面描述：

public class MainMenuFragment extends Fragment { 

@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 
// Inflate the layout for this fragment 

    return inflater.inflate(R.layout.main_menu_fragment, container, false);  
} 

@Override 
public void onActivityCreated(Bundle savedInstanceState) 
{ 
    super.onCreate(savedInstanceState); 

    GridView itemsGridViewObj = (GridView) findViewById(R.id.itemsGridView); 

    itemsGridViewObj.setOnItemClickListener(new OnItemClickListener() { 

    @Override 
    public void onItemClick(AdapterView<?> arg0, View arg1, int position, 
      long arg3) { 

     Log.d(TAG, "--> onItemClick listener..."); // You should see this now 
     /*if(position == 1) { 
      FruitMenuFragment fruitMenuFragment = new FruitMenuFragment(); 
      fragmentTransaction.replace(android.R.id.content, fruitMenuFragment); 
      fragmentTransaction.commit(); 
     }*/ 
    }}); 
} 
}
