Question

在ListView中onItemLongClick正在触发，但onItemClick未被触发。我希望触发onItemClick和onItemLongClick。

onItemClick将调用商品详情活动

onItemLongClick会喜欢这个项目

这是我的代码：

public class myClass extends ListFragment implements OnItemClickListener ,OnItemLongClickListener


public View onCreateView(LayoutInflater inflater,
                             @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        //System.out.println("<<<<<<<<<<<<<<<<<<<<Boy in onCreateView>>>>>>>>>>>>>>>>>>>>");

        View v = inflater.inflate(R.layout.boy, container, false);
        lvBNames = (ListView) v.findViewById(android.R.id.list);


        searchView = (SearchView) v.findViewById(R.id.action_search);

        if (searchView == null )
        {
            //System.out.println("Unable to instantiate");
        }



        pop_data();
        adapter = new ListBNamesAdapter(getActivity(),mBNamesList);
        lvBNames.setSmoothScrollbarEnabled(false); //android:smoothScrollbar="true"
        lvBNames.setAdapter(adapter);
        //lvBNames.setOnItemClickListener(this);
        //lvBNames.setOnItemLongClickListener(this);

        //////////////////////////////////////// Test 28 Feb 17
        /// onItemClick is not triggering ............!
        lvBNames.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                Toast.makeText(activity, "Click", Toast.LENGTH_SHORT).show();
            }
        });


/// setOnItemLongClickListener is triggering ............! :)
            lvBNames.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
                @Override
                public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {

                    Toast.makeText(activity, "Long Click", Toast.LENGTH_SHORT).show();
                    return true;
                }
            });

            lvBNames.setTextFilterEnabled(true);

            return v;
        }

任何示例程序都将受到赞赏

Answer 1

如果您在列表视图中使用任何布局，请使用...

android:descendantFocusability="blocksDescendants"

必须应用于列表中的第一个父级。它将呈现单击列表项。

Answer 2

尝试在onItemLongClick而不是true

中返回

var newTable = request.responseXML.documentElement.getElementsByTagName('table');

列表AdapterView onItemClick未触发
