在此处输入图像描述我用标签导航创建了两个标签。每个选项卡都有带有自定义适配器的网格视图。我的问题是网格视图的项目单击正在使用一个选项卡，但在第二个选项卡项目中单击不起作用。你们能建议我为什么吗？请

第一个标签：这里项目点击工作：

public class MyPictureFragment extends Fragment implements OnItemLongClickListener{

    private final static String TAG="MyPictureFragment";
    private static SharedPreferences Prefs = null;
    private static String prefname = "galleryPrefs";
    private GridView gridview=null;
    List<PartnerImage_Model> list_images=new ArrayList<PartnerImage_Model>();
    TextView textviwe;
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.mypictureuploaded, container, false);
        gridview=(GridView)view.findViewById(R.id.gridView_pic);
        textviwe= (TextView)view.findViewById(R.id.textView);
        gridview.setOnItemLongClickListener(this);




        return view;
     }

    @Override
    public boolean onItemLongClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
        Toast.makeText(getActivity(), "onClick click", Toast.LENGTH_LONG).show();

        return false;
    }


}

第二个标签代码：

public class MyVideoFragment extends Fragment implements OnItemLongClickListener{

    private final static String TAG="MyVideoFragment";
    private static SharedPreferences Prefs = null;
    private static String prefname = "galleryPrefs";
    private GridView gridview=null;
    List<PartnerVideo_Model> list_video=new ArrayList<PartnerVideo_Model>();
    TextView textviwe;
     @Override
     public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
         View view = inflater.inflate(R.layout.myvideouploaded, container, false);
         gridview=(GridView)view.findViewById(R.id.gridView_video);
        gridview.setOnItemLongClickListener(this);


         return view;
}

    @Override
        public boolean onItemLongClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
            Toast.makeText(getActivity(), "onClick click", Toast.LENGTH_LONG).show();

            return false;
        }



}

注意：true从onItemLongClick方法返回。IE

@Override
        public boolean onItemLongClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
            Toast.makeText(getActivity(), "onClick click", Toast.LENGTH_LONG).show();

            return true;
        }
