OnClickListener not working for first item in GridView inside ViewPager - android-layout

Question

Inside ViewPager, there is a gridview which has a grid of single choice answers with textviews and images. When i clicked on any answer, the textview should change its color to RED else WHITE. Its working fine for all the other answers except the first one. When i first clicked on first answer in gridview, it doesn't change the color, on second click it turns to RED, but then when i change the option, the RED color doesn't change to WHITE for first option. Look at the screen below,
Sorry Screen submission is not allowed for me as i am a new user...
Inside GridFragment#OnActivityCreated():
gridview.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View v, int position, long arg3) {
currentPage = new TestTopics().getCuttentPage();
tv = ((ViewHolder) v.getTag()).lbl;
if(selectedValues.containsKey(currentPage))
{
selectedValues.get(currentPage).setTextColor(Color.WHITE);
selectedValues.remove(currentPage);
selectedValues.put(currentPage, tv);
selectedValues.get(currentPage).setTextColor(Color.RED);
}
else
{
selectedValues.put(currentPage, tv);
selectedValues.get(currentPage).setTextColor(Color.RED);
}
}
});
ImageAdapter#getView() method:
public View getView(int position, View convertView, ViewGroup parent) {
numTopics = mTopicList.getNumTopics ();
ViewHolder holder;
holder = new ViewHolder();
if (convertView == null) {
int layoutId = R.layout.demo_pager_grid_item;
LayoutInflater li = ((Activity) mContext).getLayoutInflater();
childView = li.inflate (layoutId, null);
holder.img = (ImageView) childView.findViewById(R.id.image);
holder.lbl = (TextView) childView.findViewById(R.id.title);
childView.setTag(holder);
} else {
childView = convertView;
holder = (ViewHolder) childView.getTag();
}
if (childView != null) {
// Set the width and height of the child view.
childView.setLayoutParams(new GridView.LayoutParams(mCellWidth, mCellHeight));
int j = position + mImageOffset;
if (j < 0) j = 0;
if (j >= numTopics) j = numTopics - 1;
imageView = (ImageView) childView.findViewById (R.id.image);
if (imageView != null) {
Resources res = mContext.getResources ();
int imagePadding = res.getDimensionPixelSize (R.dimen.grid_image_padding);
imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
imageView.setBackgroundResource (R.color.background_grid1_cell);
imageView.setPadding (imagePadding, imagePadding, imagePadding, imagePadding);
imageView.setImageBitmap (mTopicList.getTopicImage (j));
imageView.setTag (new Integer (j));
}
textView = (TextView) childView.findViewById (R.id.title);
if (textView != null)
{
textView.setText(mTopicList.getTopicTitle (j));
textView.setTag (mTopicList.getTopicTitle (j));
holder.lbl.setTag(mTopicList.getTopicTitle (j));
}
}
return childView;
}

have solved it....
I added gridview.setBackgroundColor(Color.TRANSPARENT); in my following code :
if(patternItems.containsKey(currentPage) && selectedValues.containsKey(currentPage))
{
selectedValues.get(currentPage).setTextColor(Color.WHITE);
selectedValues.remove(currentPage);
selectedValues.put(currentPage, tv);
selectedValues.get(currentPage).setTextColor(Color.RED);
**gridview.setBackgroundColor(Color.TRANSPARENT);**
patternItems.remove(currentPage);
patternItems.put(currentPage,tv.getText().toString());
}
else
{
selectedValues.put(currentPage, tv);
selectedValues.get(currentPage).setTextColor(Color.RED);
**gridview.setBackgroundColor(Color.TRANSPARENT);**
patternItems.put(currentPage,tv.getText().toString());
}
