Problem Solved:

The child view in the grid view do not re-calculate its layout when the grid view changes the column on runtime.

In your BaseAdapter, you should call forceLayout() to calculate its layout.

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


    if (null == convertView) {
        convertView = mInflater.inflate(
                R.layout.mnm_customer_user_thumbnail, null);

        control.txtUserName = (TextView) convertView
                .findViewById(R.id.mnmTxtStudentName);
        control.image = (ImageView) convertView
                .findViewById(R.id.mnmImageStudent);
        control.imageCheckBox = (ImageView) convertView
                .findViewById(R.id.mnmImageCheckBox);
        control.mnmOuterBounder = (RelativeLayout) convertView
                .findViewById(R.id.mnmOuterBound);
        convertView.setTag(control);
    } else {
        convertView.forceLayout();
    }
