Android ListView如何获取点击不在项目上

ListView listView = findViewById(R.id.listView);

listView.setOnTouchListener(new View.OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent event) {
        int action = event.getAction();
        int x = (int) event.getX();
        int y = (int) event.getY();

        if (action == MotionEvent.ACTION_DOWN) {
            int position = listView.pointToPosition(x, y);
            if (position == ListView.INVALID_POSITION) {
                // 点击位置不在ListView的项目上
                // 执行相应的操作
            }
        }

        return false;
    }
});
