我有一个上下文操作模式片段。上下文操作模式运行良好。 ActionMode.Callback具有onActionItemClicked方法。我想在课堂上重写此方法。下面是我尝试过的代码。不调用类中的override方法。

public class HouseHoldMembersFragment extends ActionBarCallBack {
        ActionMode mMode;
        public HouseHoldMembersFragment() {
        }
    @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);

        }

        @Override
        public boolean onActionItemClicked(ActionMode mode, MenuItem item) {

            return false;
        }
        @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container,
                                 Bundle savedInstanceState) {

            View view = inflater.inflate(R.layout.fragment_house_hold_members, container, false);
            ExpandList = (ExpandableListView) view.findViewById(R.id.expandable_list_view);


            ExpandList.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
                @Override
                public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {
                    if (ExpandableListView.getPackedPositionType(id) == ExpandableListView.PACKED_POSITION_TYPE_GROUP) {
                        mMode = view.startActionMode(new ActionBarCallBack());


                        return true;
                    }
                    return false;
                }
            });
            return view;
        }


这是实现类

public class ActionBarCallBack extends Fragment implements ActionMode.Callback {
    ActionMode mMode;

    @Override
    public boolean onActionItemClicked(ActionMode mode, MenuItem item) {

        return false;
    }

    @Override
    public boolean onCreateActionMode(ActionMode mode, Menu menu) {
        // TODO Auto-generated method stub
        mode.getMenuInflater().inflate(com.deerwalk.androidcommon.R.menu.context_action_menu, menu);
        return true;
    }

    @Override
    public void onDestroyActionMode(ActionMode mode) {
        mMode = null;

    }

    @Override
    public boolean onPrepareActionMode(ActionMode mode, Menu menu) {
        // TODO Auto-generated method stub

        mode.setTitle("Action");
        return false;
    }


}


我想将ActionMode设为通用并覆盖onActionItemClicked方法。到目前为止,我已经尝试过,但是没有调用我的类onActionItemClicked方法。如何解决这个问题。

最佳答案

请尝试以下操作:

ExpandList.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener()
{
    @Override
    public boolean onItemLongClick (AdapterView < ? > parent, View view,int position, long id){
    if (ExpandableListView.getPackedPositionType(id) == ExpandableListView.PACKED_POSITION_TYPE_GROUP) {
        startSupportActionMode(new ActionMode.Callback() {
            @Override
            public boolean onActionItemClicked(ActionMode mode, MenuItem item) {

                return false;
            }

            @Override
            public boolean onCreateActionMode(ActionMode mode, Menu menu) {
                // TODO Auto-generated method stub
                mode.getMenuInflater().inflate(com.deerwalk.androidcommon.R.menu.context_action_menu, menu);
                return true;
            }

            @Override
            public void onDestroyActionMode(ActionMode mode) {
                mMode = null;

            }

            @Override
            public boolean onPrepareActionMode(ActionMode mode, Menu menu) {
                // TODO Auto-generated method stub

                mode.setTitle("Action");
                return false;
            }

        });
    }
}
