防止由于方向更改而导致android状态更改

Question

I use an SQLiteDatabase in my application which I created manually and then using it in the android application. To navigate through it I am using a Cursor. I am showing the results from rows in edit texts.

When the orientation changes, irrespective of the row which was shown, the first row is shown in the edit Text. I know that android recreates the activity on orientation change and calls onCreate() method again.

But according to the documentation , I shouldn't store a Cursor Object in onRetainNonConfigurationInstance() since it uses a Context.

Here is the code for creating Cursor.

DataBaseHelper myDbHelper = new DataBaseHelper(this);
Cursor c=myDbHelper.getDatabase().rawQuery("SELECT * FROM mytable",null);

Another recommended way is to handle the changes manually, but I do not want to do so since I want to take advantage of the default adjustment of UI.

How can I continue with the same row when the orientation changes ?

最简单的方法之一是将其添加到清单文件中（用于相关活动）-

android:configChanges="orientation|screenSize|keyboardHidden"
