I have given my code from which I am trying to launch my 3rd Activity. But its, not responding anything so I tried using code but Toast also doesn't appeared. Please help. I am very new to stackover flow. Please Ignore My Mistake and suggest. Thank You

If you grid items contains focusable items then try after adding `android:descendantFocusability="blocksDescendants"` to root of item layout . — ADM, Feb 16 '18 at 10:41

Have a look at this question. Though it is about ListViews you should be able to adopt.

My suggest would be to add an View.OnClickListener to your convertView in your adapter just before returning it.

Handle the onItemClick via an interface in your Activity and you're good to go.

Add this lines and try

View gridViewAndroid;
if (convertView == null) {
    LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    gridViewAndroid = inflater.inflate(R.layout.landing_grid_brand_layout_design, null);
} else {
    gridViewAndroid = (View) convertView;
}

and for click use

gridViewAndroid.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        //your click action
    }
});

the question is about `onItemClick()`. This is just a workaround same as `RecyclerView`. – ADM Feb 16 '18 at 10:32
convertView is initialised with null, with what I should initialise gridView, because it is aking to create local variable in GridAdapter.java. – Alok Raj Feb 16 '18 at 10:33
