执行过滤器查询搜索时更改IllegalStateException方向

我已使用自定义listview上的searchview和setFilterQueryProvider在SimpleCursorAdapter中实施了搜索。

在我的片段的onActivityCreated中，我通过以下代码设置过滤器

myAdapter.setFilterQueryProvider(new FilterQueryProvider(){

                @Override
                public Cursor runQuery(CharSequence constraint) {


                    returnget Activity().getBaseContext().getContentResolver().
                            query(  Uri.parse("content://com.DBProvider/getEmployeeByName"),
                            EMP.PROJECTION, EMP.EMP_NAME + " LIKE '"+ constraint+"%'", null, null);;

                }


            });

       // this code is outside `setFilterQueryProvider`
        getActivity().getSupportLoaderManager().initLoader(EMP_INFO.ID, null, this);

现在的问题是，当我改变方向时，我收到了IllegalStateException异常。

修改

我发现以下行导致问题时，方向更改为内部onActivityCreated，所以我如何防止这种情况，在方向更改时我想要在最后一个搜索项目（之前的状态）。< / p> 

    getActivity().getSupportLoaderManager().initLoader(EMP_INFO.ID, null, this);

1 个答案:

答案 0 :(得分：2)

尝试将此代码放在AndroidManifest中：

android:configChanges="keyboardHidden|orientation|screenSize"

希望不要迟到;）
