So, the issue is with how you're creating the View in this method, and there's a couple of things going wrong:

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

    LinearLayout linearlayout=new LinearLayout(mContext);
    ImageView imageView = new ImageView(mContext);
    TextView textView =new TextView(mContext);
    textView.setGravity(Gravity.CENTER);
    linearlayout.setOrientation(LinearLayout.VERTICAL);
    imageView.setImageResource(mThumbIds[position]);
    imageView.setScaleType(ImageView.ScaleType.CENTER_INSIDE);
    imageView.setLayoutParams(new GridView.LayoutParams(230, 230));
    textView.setText(mThumbTxt[position]);

    linearlayout.addView(imageView);
    linearlayout.addView(textView);
    return linearlayout;
}

1) Right now, you're ignoring the convertView, so you're wasting GridViews recycling mechanism by not checking if that is null before instantiating the View.

2) You're attaching GridView.LayoutParams to a child View nested within a LinearLayout. The LinearLayout should have GridView.LayoutParams, but the LinearLayout's children should have LinearLayout.LayoutParams.

3) There's a difference between layout_gravity, and gravity -- you're using gravity, which for LinearLayout won't work as you think it should. (Unless in this context you change your TextView to be match_parent for width, but then that might mess other things up)

I'd recommend ditching the dynamic creation and taking an XML inflation approach.
