Question

在调用onItemClick时，我不想呼叫onItemLongClick。我正在使用SlideAndDragListView并仅在onItemLongClick中返回true。

matchedUsersListView.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
        @Override
        public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) { 
            InviteMatchedUsersFragment.this.onItemLongClick(parent,view,position,id);
            return true;
        }
    });

 @Override
    public void onItemLongClick(AdapterView<?> parent, View view, int position, long id) {  
        ImageView view1 = (ImageView) view.findViewById(position);
        matchedPassengersAdapter.onUserClick(view1, position);
    }

在OnItemClick中，我的做法有所不同

@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
    Log.d(LOG_TAG, "onMatchedUserSelection()");
    if(matchedPassengersAdapter.getSelectedPassengersCount() != 0)
    {
        ImageView view1 = (ImageView) view.findViewById(position);
        matchedPassengersAdapter.onUserClick(view1, position);
    }
    else {
          //onItemClickGoesHere
    }

}

@Override
    public void onItemLongClick(AdapterView<?> parent, View view, int position, long id) {  
        ImageView view1 = (ImageView) view.findViewById(position);
        matchedPassengersAdapter.onUserClick(view1, position);
    }

这可能对您有帮助

参考：Set long click listener for listview

您的问题与this one非常相似，但看起来并非完全相同。

您已经注意到，ListActivity类没有专门针对这种情况的方法覆盖。

为了将此功能添加为方法覆盖，您的类应实现AdapterView.OnItemLongClickListener接口，然后可以添加onItemLongClick（）方法覆盖，其作用与已具有的onListItemClick（）方法覆盖一样，但响应长点击。

只要确保您遵循this answer中的说明，就必须在布局xml中使用android：longClickable =“ true”，或调用listview.setLongClickable（true）;

Ex

public class MainActivity extends ListActivity implements AdapterView.OnItemLongClickListener {

    ListView listview;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        ListView listview = (ListView) findViewById(R.id.list);

        listview.setLongClickable(true);

    }

    @Override
    public boolean onItemLongClick(AdapterView<?> l, View v,
                                   final int position, long id) {

        Toast.makeText(this, "long clicked pos: " + position, Toast.LENGTH_LONG).show();

        return true;
    }

    protected void onListItemClick(ListView l, View v, final int position, long id) {
        super.onListItemClick(l, v, position, id);

        Toast.makeText(this, "short clicked pos: " + position, Toast.LENGTH_LONG).show();  

    }

调用onItemLongClickListener时，即使我在onItemLongClick中返回true，onItemClickListener也会调用
