Answer 1

我们假设您的AdapterView为ListView

listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
        if (position == 0) {
            Intent intent = new Intent(TopLevelActivity.this, DrinkCategoryActivity.class);
            startActivity(intent);

Answer 2

您需要将听众设置为ListView。这就是它无法正常工作的原因。

这样做：

AdapterView.OnItemClickListener itemClickListener = 
      new AdapterView.OnItemClickListener() {  ... }; // create listener (you did that already)

listView.setOnItemClickListener(itemClickListener); // set listener
