    </RelativeLayout>

    <!-- attending event -->

    <ImageView

        android:padding="30dp"
        android:src="@drawable/v"
        android:visibility="gone" />

</RelativeLayout>

我正在设置一个 onItemClickedListener：

private void setGridView()
{
    //create a new event list
    picoEventsList = new ArrayList<PicoEvent>();
    //create new gridview arrayadapter
    arrayAdapter = new EventDetailsArrayAdapter(getActivity(), picoEventsList);
    //set grid's view empty view
    View emptyView = LayoutInflater.from(getActivity()).inflate(R.layout.fragment_events_empty_view, null);     
    gridView.setEmptyView(emptyView);
    gridView.setOnItemClickListener(this);
    gridView.setAdapter(arrayAdapter);

}

@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {      
    //get clicked event
    PicoEvent event = arrayAdapter.getItem(arg2);
    //create new event details fragment
    EventDetailsFragment eventDetailsFragment = new EventDetailsFragment();
    //add the event to fragment's arguments
    eventDetailsFragment.setArguments(PicoEventCreator.createBundle(event));
    //show the event details fragment
    getMainActivity().showFragment(null, eventDetailsFragment, true, true);

}

但是 onItemClick() 方法没有被解雇..

我已经检查过，并且我的布局中的视图都没有设置 clickable="true" ...

有任何想法吗 ？

嘿家伙终于有一个解决方案......

我们所做的是直接访问 GridView 内的 Layout，因此 onItemClickListener 发现访问项目很混乱。

所以解决方案是在Adapter内部应用onClickListener（即通常是ArrayAdapter）

所以我想说的是：

public View getView(int position, View convertView, ViewGroup parent) {

            //Here row is a view and we can set OnClickListener on this
    final View row;
    ViewHolder holder = null;

    if (convertView == null) {
        LayoutInflater inflater = ((Activity) context).getLayoutInflater();
        //Here we inflate the layout to view (linear in my case)
        row = inflater.inflate(layoutResourceId, parent, false);
        holder = new ViewHolder();
        holder.imageTitle = (TextView) row.findViewById(R.id.text);
        holder.image = (ImageView) row.findViewById(R.id.image);
        row.setTag(holder);
    } else {
        row = convertView;
        holder = (ViewHolder) row.getTag();
    }

    ImageItem item = data.get(position);
    holder.imageTitle.setText(item.getTitle());
    holder.image.setImageBitmap(item.getImage());

    //Now get the id or whatever needed
    row.setId(position);
    // Now set the onClickListener
    row.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            Toast.makeText(context, "Clicked" + row.getId() + "!!",
                    Toast.LENGTH_SHORT).show();
        }
    });
    return row;
}

好的，我发现了问题所在

显然 GridView 和 HorzonitalScrollView 不是那么好的朋友......

可能是因为 HorzonitalScrollView 具有 onClick funcionality..

我找到的解决方案是：

android:descendantFocusability="blocksDescendants"

在我的 ArrayAdapter 根视图中。
