谢谢!

是的,tsync发布的解决方案对我有用。我也遇到了同样的问题,并认为这是不可能的。我尝试了以上建议如下:
public class ProjectsFragment extends ListFragment {
@Override
public void onActivityCreated(Bundle savedState) {
super.onActivityCreated(savedState);
getListView().setOnItemLongClickListener(new OnItemLongClickListener() {
@Override
public boolean onItemLongClick(AdapterView<?> arg0, View arg1,
int arg2, long arg3) {
Toast.makeText(getActivity(), "On long click listener", Toast.LENGTH_LONG).show();
return true;
}
});
它有效!

根据您想要实现的内容,您可以将给定的方法用于上下文菜单:
首先注册长期按下的View类(在Fragment类中):
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
registerForContextMenu(this.getListView());
}
要实现这两种方法,要创建上下文菜单,并在单击菜单项时执行任何操作:
@Override
public void onCreateContextMenu(ContextMenu menu, View v, ContextMenu.ContextMenuInfo menuInfo) {
super.onCreateContextMenu(menu, v, menuInfo);
MenuInflater inflater = this.getActivity().getMenuInflater();
inflater.inflate(R.menu.my_context_menu, menu);
}
@Override
public boolean onContextItemSelected(MenuItem item) {
AdapterView.AdapterContextMenuInfo info = (AdapterView.AdapterContextMenuInfo) item.getMenuInfo();
switch (item.getItemId()) {
case R.id.add: // <-- your custom menu item id here
// do something here
return true;
default:
return super.onContextItemSelected(item);
}
}

这对我有用
getListView().setOnItemLongClickListener(new OnItemLongClickListener() {
public boolean onItemLongClick(AdapterView<?> av, View v, int position, long id) {
//Get your item here with the position
return true;
}
});
