If you want to show the alphabet clicked as a Toast (a custom toast like the one shown in the image) use this:

view.setOnClickListener(new View.OnClickListener() {
    public void onClick(View v) {
        LayoutInflater inflater = getLayoutInflater();
        View layout = inflater.inflate(R.layout.toast_custom_layout,
        (ViewGroup) findViewById(R.id.toast_layout_root));
        Toast toast = new Toast(getApplicationContext());
        toast.setGravity(Gravity.BOTTOM, 0, 0);
        // to position the Toast on the screen
        toast.setDuration(Toast.LENGTH_LONG);
        // to set the duration, the toast should appear
        toast.setView(layout);
        // a custom layout for the toast
        toast.show();
    }
});

and your toast_custom_layout.xml will be a 100 x 100 layout with large text size
