Question

是否有任何API可以跟踪Android中GridView的索引？

Answer 1

你有没有设置OnItemClickListener你的GridView？

gridView.setOnItemClickListener(
    new OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            Toast.makeText(
                getApplicationContext(), 
                String.format("Clicked on position #%s (id = %s)", position, id), 
                Toast.LENGTH_SHORT
            ).show();
        }   
    }
);
