Question

I’ve designed a GridView with custom item layout and there is one ImageView on the top-left corner, another ImageView on the top-right corner, a main ImageView and Text in the center.

I need to set the OnClickListener for both two ImageView on the corner and the OnItemClickListener for the adapter.

Everything worked fine but only the first item in the GridView can’t trigger the OnClickListener. Can anyone solve this problem?

P.S. I found the first item ImageView’s OnClickListener will trigger when I do the next action(e.g. Click other items)

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    View v = convertView;
    TagView tag;
    if (convertView == null) {
        v = m_LayoutInflater.inflate(R.layout.mydoc_grid_item, null);
        tag = new TagView(
                (ImageView) v.findViewById(R.id.myDoc_GridItem_IV),
                (TextView) v.findViewById(R.id.myDoc_GridItem_TV),
                (ImageView) v.findViewById(R.id.iViewAdd2Category),
                (ImageView) v.findViewById(R.id.iViewDelete));
        v.setTag(tag);
    } else {
        tag = (TagView) v.getTag();
    }

    v.setLayoutParams(new GridView.LayoutParams((int) (180 * v
            .getResources().getDisplayMetrics().density), (int) (180 * v
            .getResources().getDisplayMetrics().density)));


    tag.image.setScaleType(ImageView.ScaleType.CENTER_CROP);
    tag.image.setImageDrawable(new BitmapDrawable(BitmapFactory.decodeFile(m_DisplayItems.get(position)
                    .get("image").toString())));
    tag.text.setText(m_DisplayItems.get(position).get("text").toString());
    tag.iAdd2Category.setVisibility((m_IsEdit) ? View.VISIBLE : View.GONE);
    tag.iDelete.setVisibility((m_IsEdit) ? View.VISIBLE : View.GONE);
    if (m_IsEdit) {
        tag.iAdd2Category.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                Log.i(LOG_TAG, "Click on image add 2 category");
            }
        });

        tag.iDelete.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                Log.i(LOG_TAG, "Click on image delete");
            }
        });
    }

    return v;
}

I finally found the answer in this article.

OnClickListener not working for first item in GridView

In my case:

if (convertView == null) {
    v = m_LayoutInflater.inflate(R.layout.mydoc_grid_item, null);
    tag = new TagView(
            (ImageView) v.findViewById(R.id.myDoc_GridItem_IV),
            (TextView) v.findViewById(R.id.myDoc_GridItem_TV),
            (ImageView) v.findViewById(R.id.iViewAdd2Category),
            (ImageView) v.findViewById(R.id.iViewDelete));
    v.setTag(tag);
} else {
    tag = (TagView) v.getTag();
}

just remove if else statement and the “tag” will be instantiated every time.
