A subclass should implement this method to create a single object using
binding information. This method is not intended to be called
outside of CursorMapper.
Called once when the associated Cursor is changed. A subclass
should bind column indexes to column names in this method. This method is
not intended to be called outside of CursorMapper.

The support library has been superseded by [AndroidX](/jetpack/androidx) which is part of [Jetpack](/jetpack). We recommend using the AndroidX libraries in all new projects. You should also consider [migrating](/jetpack/androidx/migrate) existing projects to AndroidX. To find the AndroidX class that maps to this deprecated class, see the AndroidX support library [class\n| mappings](/jetpack/androidx/migrate/class-mappings).\n\n\n`\npublic\n\n\nabstract\nclass\nCursorMapper\n`\n\n\n`\n\nextends Object\n\n\n`\n\n`\n\n\n`\n\n|---|----------------------------------------------------|\n| java.lang.Object ||\n| ↳ | android.support.v17.leanback.database.CursorMapper |\n\n\u003cbr /\u003e\n\n*** ** * ** ***\n\nAbstract class used to convert the current [Cursor](https://developer.android.com/reference/android/database/Cursor.html) row to a single\nobject.\n\nSummary\n-------\n\n| ### Public constructors ||\n|------------------------------------------------------------------------------------------------------|---|\n| ` `[CursorMapper](/reference/android/support/v17/leanback/database/CursorMapper#CursorMapper())`() ` |\n\n| ### Public methods ||\n|-----------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n| ` Object` | ` `[convert](/reference/android/support/v17/leanback/database/CursorMapper#convert(android.database.Cursor))`(`[Cursor](https://developer.android.com/reference/android/database/Cursor.html)` cursor) ` Convert a [Cursor](https://developer.android.com/reference/android/database/Cursor.html) at its current position to an Object. |\n\n| ### Protected methods ||\n|--------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n| ` abstract Object` | ` `[bind](/reference/android/support/v17/leanback/database/CursorMapper#bind(android.database.Cursor))`(`[Cursor](https://developer.android.com/reference/android/database/Cursor.html)` cursor) ` A subclass should implement this method to create a single object using binding information. |\n| ` abstract void` | ` `[bindColumns](/reference/android/support/v17/leanback/database/CursorMapper#bindColumns(android.database.Cursor))`(`[Cursor](https://developer.android.com/reference/android/database/Cursor.html)` cursor) ` Called once when the associated [Cursor](https://developer.android.com/reference/android/database/Cursor.html) is changed. |\n\n| ### Inherited methods |\n|-----------------------|---|\n| From class ` java.lang.Object ` |-------------------|-------------------------------| | ` Object` | ` clone() ` | | ` boolean` | ` equals(Object arg0) ` | | ` void` | ` finalize() ` | | ` final Class\u003c?\u003e` | ` getClass() ` | | ` int` | ` hashCode() ` | | ` final void` | ` notify() ` | | ` final void` | ` notifyAll() ` | | ` String` | ` toString() ` | | ` final void` | ` wait(long arg0, int arg1) ` | | ` final void` | ` wait(long arg0) ` | | ` final void` | ` wait() ` | ||\n\nPublic constructors\n-------------------\n\n### CursorMapper\n\nadded in [version 22.1.0](/topic/libraries/support-library/revisions) \n\n```\nCursorMapper ()\n```\n\n\u003cbr /\u003e\n\n\u003cbr /\u003e\n\nPublic methods\n--------------\n\n### convert\n\nadded in [version 22.1.0](/topic/libraries/support-library/revisions) \n\n```\nObject convert (Cursor cursor)\n```\n\nConvert a [Cursor](https://developer.android.com/reference/android/database/Cursor.html) at its current position to an Object.\n\n\u003cbr /\u003e\n\n| Parameters ||\n|----------|-----------------|\n| `cursor` | `Cursor` \u003cbr /\u003e |\n\n| Returns ||\n|----------|--------|\n| `Object` | \u003cbr /\u003e |\n\nProtected methods\n-----------------\n\n### bind\n\nadded in [version 22.1.0](/topic/libraries/support-library/revisions) \n\n```\nObject bind (Cursor cursor)\n```\n\nA subclass should implement this method to create a single object using\nbinding information.
