Android的：不能同时设置：setOnItemClickListener setOnScrollListener？

问题描述

class MyActivity extends Activity implements OnScrollListener,  OnItemClickListener {
...
listView.setOnItemClickListener(this);
listView.setOnScrollListener(this);  // why not work with previous line?
...

添加ListView.setOnScrollListener后（本）

After adding ListView.setOnScrollListener(this)

onItemClick（...）不再触发。

onItemClick(...) no longer triggered.

有人知道为什么吗？

感谢。

推荐答案

我不明白为什么它不应该工作，

I don't see why it shouldn't work,

试试这个：

  getListView().setOnScrollListener(onAnswersScrolled);
  getListView().setOnItemClickListener(onAnswerClicked);

---

private OnItemClickListener onAnswerClicked = new OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position,
                long id) {
            // 
                Intent i = new Intent();

                setResult(RESULT_OK, i);
                finish();
        }

    };

    private OnScrollListener onAnswersScrolled = new OnScrollListener() {

        @Override
        public void onScrollStateChanged(AbsListView view, int scrollState) {
            // not used
        }

        @Override
        public void onScroll(AbsListView view, int firstVisibleItem,
                int visibleItemCount, int totalItemCount) {
            // do something
            }
        }
    };
