Android 是否可以在同一活动中选择多个OnContextItem

在和的帮助下，我为两个列表视图创建了一个上下文菜单，如下所示

    final int DELETE = 0;
    final int CANCEL = 1;
@Override
public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo){
    super.onCreateContextMenu(menu, v, menuInfo);
    switch(v.getId()){
    case R.id.history_listView:
        menu.setHeaderTitle("Delete History?");
        menu.add(0, DELETE, 0, "Delete");
        menu.add(0, CANCEL, 0, "Cancel");
        break;

    case R.id.bookmark_listView:
        menu.setHeaderTitle("Delete Bookmark?");
        menu.add(0, DELETE, 0, "Delete");
        menu.add(0, CANCEL, 0, "Cancel");
    }
}

现在我想要两个onContextItemSelected方法，一个用于历史记录，另一个用于书签。我已经为历史创造了一个，它运行良好

@Override
public boolean onContextItemSelected(MenuItem item){
    AdapterContextMenuInfo info = (AdapterContextMenuInfo) item.getMenuInfo();

    switch(item.getItemId()){
    case DELETE:
        String deleteSelectedHistory = (String) historyData.get(info.position);
        historyData.remove(info.position);
        historyAdapter.notifyDataSetChanged();

        break;

    case CANCEL:
        break;
    }
    return false;
}

但我无法为书签创建另一个。是否可以在同一活动中使用另一个onContextItemSelected方法？或者有办法创建第二个吗？

请检查此代码。这可能对你有帮助

final int HIS_DELETE = 0;
final int HIS_CANCEL = 1;
final int BM_DELETE = 2;
final int BM_CANCEL = 3;

@Override
public void onCreateContextMenu(ContextMenu menu, View v,
        ContextMenuInfo menuInfo) {
    super.onCreateContextMenu(menu, v, menuInfo);
    switch (v.getId()) {
    case R.id.history_listView:
        menu.setHeaderTitle("Delete History?");
        menu.add(0, HIS_DELETE, 0, "Delete");
        menu.add(0, HIS_CANCEL, 0, "Cancel");
        break;

    case R.id.bookmark_listView:
        menu.setHeaderTitle("Delete Bookmark?");
        menu.add(0, BM_DELETE, 0, "Delete");
        menu.add(0, BM_CANCEL, 0, "Cancel");
    }
}

和onContextItemSelected方法，如

    @Override
public boolean onContextItemSelected(MenuItem item) {
    AdapterContextMenuInfo info = (AdapterContextMenuInfo) item
            .getMenuInfo();

    switch (item.getItemId()) {
    case HIS_DELETE:
        Log.d("System out", "HIS_DELETE");
        break;
    case HIS_CANCEL:
        Log.d("System out", "HIS_CANCEL");
        break;
    case BM_DELETE:
        Log.d("System out", "BM_DELETE");
        break;
    case BM_CANCEL:
        Log.d("System out", "BM_CANCEL");
        break;
    }
    return false;
}

只需为历史记录和书签声明不同的ID即可。HIS_DELETE，HIS_CANCEL，BM_DELETE，BM_CANCEL.@HirenDabhi那么我如何检查按下了哪个删除，在onContextItemSeletedJust中，必须为历史记录和书签声明不同的ID。例如。他的删除，他的取消，BM删除，BM取消。@HirenDabhi那么在OnContextItemsSelete中，我如何检查按下了哪个删除，我遇到了这个问题，因为我觉得运气不错。为什么没有更多的选票？经过5年的进一步发展，你还发现这个最佳实践吗？我遇到了这个问题，因为我觉得运气不错。为什么没有更多的选票？经过5年的进一步发展，您是否仍能找到这一最佳实践？
