SimpleCursorAdapter, Move the cursor at API level below 11

Question

Trying to implement LoaderManager + CursorLoader.

In the onFinish adapter, the adapter should change its cursor

public void onLoadFinished(Loader<Cursor> loader, Cursor data) { // Swap the new cursor in. (The framework will take care of closing the // old cursor once we return.) mAdapter.swapCursor(data); } 

But swapCursor is available with a level 11 API.

So, how do I change the cursor in the Android 10 API?

Answer 1

The compatibility library required implementation.

This is http://developer.android.com/reference/android/support/v4/widget/SimpleCursorAdapter.html

Answer 2

If you follow the Android Studio suggestion for wrapping and swapCursor an explanation that the old cursor was not close using android.widget. CursorAdapter, you get:

 public void onLoadFinished(Loader<Cursor> loader, Cursor data) { if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) { mAdapter.swapCursor(data); } else { Cursor oldCursor = mAdapter.getCursor(); mAdapter.changeCursor(data); oldCursor.close(); } }
