| | [Int](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-int/index.html) | [FLAG_REGISTER_CONTENT_OBSERVER](https://developer.android.com/reference/kotlin/android/widget/CursorAdapter#FLAG_REGISTER_CONTENT_OBSERVER:kotlin.Int) If set the adapter will register a content observer on the cursor and will call [onContentChanged()](https://developer.android.com/reference/kotlin/android/widget/CursorAdapter#onContentChanged()) when a notification comes in. Be careful when using this flag: you will need to unset the current Cursor from the adapter to avoid leaks due to its registered observers. This flag is not needed when using a CursorAdapter with a [android.content.CursorLoader](https://developer.android.com/reference/kotlin/android/content/CursorLoader.html#).

This query is requested by the filter attached to this adapter. The query is provided by a [android.widget.FilterQueryProvider](https://developer.android.com/reference/kotlin/android/widget/FilterQueryProvider). If no provider is specified, the current cursor is not filtered and returned.

This method is always executed on a background thread, not on the application's main thread (or UI thread.)

Unlike [changeCursor(android.database.Cursor)](https://developer.android.com/reference/kotlin/android/widget/CursorAdapter#changeCursor(android.database.Cursor)), the returned old Cursor is *not* closed.

```
ResourceCursorAdapter(
context: Context!,
layout: Int,
c: Cursor!)
```
**Deprecated:** *This option is discouraged, as it results in Cursor queries being performed on the application's UI thread and thus can cause poor responsiveness or even Application Not Responding errors. As an alternative, use [android.app.LoaderManager](https://developer.android.com/reference/kotlin/android/app/LoaderManager.html#) with a [android.content.CursorLoader](https://developer.android.com/reference/kotlin/android/content/CursorLoader.html#).*
Constructor the enables auto-requery.
| Parameters ||
|-----------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| `context` | [Context](https://developer.android.com/reference/kotlin/android/content/Context.html#)!: The context where the ListView associated with this adapter is running |
| `layout` | [Int](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-int/index.html): resource identifier of a layout file that defines the views for this list item. Unless you override them later, this will define both the item views and the drop down views. |
### ResourceCursorAdapter
Added in [API level 3](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels)
```
ResourceCursorAdapter(
context: Context!,
layout: Int,

autoRequery: Boolean)
```
Constructor with default behavior as per [CursorAdapter.CursorAdapter(Context, Cursor, boolean)](https://developer.android.com/reference/kotlin/android/widget/CursorAdapter#CursorAdapter(android.content.Context,%20android.database.Cursor,%20kotlin.Boolean)); it is recommended you not use this, but instead [ResourceCursorAdapter(android.content.Context,int,android.database.Cursor,int)](https://developer.android.com/reference/kotlin/android/widget/ResourceCursorAdapter#ResourceCursorAdapter(android.content.Context,%20kotlin.Int,%20android.database.Cursor,%20kotlin.Int)). When using this constructor, [FLAG_REGISTER_CONTENT_OBSERVER](https://developer.android.com/reference/kotlin/android/widget/CursorAdapter#FLAG_REGISTER_CONTENT_OBSERVER:kotlin.Int) will always be set.

| `autoRequery` | [Boolean](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-boolean/index.html): If true the adapter will call requery() on the cursor whenever it changes so the most recent data is always displayed. Using true here is discouraged. |
