For a query such as:`SELECT name, birth, phone FROM myTable WHERE ... LIMIT 1,20 ORDER BY...`the column names (name, birth, phone) would be in the projection argument and everything from`FROM`onward would be in the params argument.
| Parameters || |-------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------| | `driver` | `SQLiteCursorDriver`
| | `editTable` | `String`: the name of the table used for this query
| | `query` | `SQLiteQuery`: the[SQLiteQuery](https://developer.android.com/reference/android/database/sqlite/SQLiteQuery)object associated with this cursor object.
| ### SQLiteCursor Added in[API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public SQLiteCursor (SQLiteDatabase db, SQLiteCursorDriver driver, String editTable, SQLiteQuery query) ```
**This constructor is deprecated.** use[SQLiteCursor(android.database.sqlite.SQLiteCursorDriver, java.lang.String, android.database.sqlite.SQLiteQuery)](https://developer.android.com/reference/android/database/sqlite/SQLiteCursor#SQLiteCursor(android.database.sqlite.SQLiteCursorDriver,%20java.lang.String,%20android.database.sqlite.SQLiteQuery))instead Execute a query and provide access to its result set through a Cursor interface. For a query such as:`SELECT name, birth, phone FROM myTable WHERE ... LIMIT 1,20 ORDER BY...`the column names (name, birth, phone) would be in the projection argument and everything from`FROM`onward would be in the params argument.
| Parameters || |-------------|-------------------------------------------------------------------------------------------------------------------------------------| | `db` | `SQLiteDatabase`: a reference to a Database object that is already constructed and opened. This param is not used any longer
| | `driver` | `SQLiteCursorDriver`
| | `editTable` | `String`: the name of the table used for this query
| | `query` | `SQLiteQuery`: the rest of the query terms cursor is finalized
| ## Public methods ### close Added in[API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public void close () ``` Closes the Cursor, releasing all of its resources and making it completely invalid. Unlike[deactivate()](https://developer.android.com/reference/android/database/Cursor#deactivate())a call to[requery()](https://developer.android.com/reference/android/database/Cursor#requery())will not make the Cursor valid again.
### deactivate Added in[API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public void deactivate () ``` Deactivates the Cursor, making all calls on it fail until[requery()](https://developer.android.com/reference/android/database/Cursor#requery())is called. Inactive Cursors use fewer resources than active Cursors. Calling[requery()](https://developer.android.com/reference/android/database/Cursor#requery())will make the cursor active again.
### getColumnIndex Added in[API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public int getColumnIndex (String columnName) ``` Returns the zero-based index for the given column name, or -1 if the column doesn't exist. If you expect the column to exist use[getColumnIndexOrThrow(java.lang.String)](https://developer.android.com/reference/android/database/Cursor#getColumnIndexOrThrow(java.lang.String))instead, which will make the error more clear.
| Parameters || |--------------|-------------------------------------------------| | `columnName` | `String`: the name of the target column.
| | Returns || |-------|-------------------------------------------------------------------------------------------------------------------------------| | `int` | the zero-based column index for the given column name, or -1 if the column name does not exist. Value is -1 or greater
| ### getColumnNames Added in[API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public String[] getColumnNames () ``` Returns a string array holding the names of all of the columns in the result set in the order in which they were listed in the result.
| Returns || |----------------------------------------------------------------------|---------------------------------------------------------| | [String[]](https://developer.android.com/reference/java/lang/String) | the names of the columns returned in this query.
| ### getCount Added in[API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public int getCount () ``` Returns the numbers of rows in the cursor.
| Returns || |-------|----------------------------------------------------------------| | `int` | the number of rows in the cursor. Value is 0 or greater
| ### getDatabase Added in[API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public SQLiteDatabase getDatabase () ``` Get the database that this cursor is associated with.
| Returns || |--------------------------------------------------------------------------------------------------|----------------------------------------------------------------| | [SQLiteDatabase](https://developer.android.com/reference/android/database/sqlite/SQLiteDatabase) | the SQLiteDatabase that this cursor is associated with.
| ### onMove Added in[API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public boolean onMove (int oldPosition, int newPosition) ``` This function is called every time the cursor is successfully scrolled to a new position, giving the subclass a chance to update any state it may have. If it returns false the move function will also do so and the cursor will scroll to the beforeFirst position.
| Parameters || |---------------|---------------------------------------------------| | `oldPosition` | `int`: the position that we're moving from
| | `newPosition` | `int`: the position that we're moving to
| | Returns || |-----------|--------------------------------------------------------| | `boolean` | true if the move is successful, false otherwise
| ### requery Added in[API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public boolean requery () ``` Performs the query that created the cursor again, refreshing its contents. This may be done at any time, including after a call to[deactivate()](https://developer.android.com/reference/android/database/Cursor#deactivate()). Since this method could execute a query on the database and potentially take a while, it could cause ANR if it is called on Main (UI) thread. A warning is printed if this method is being executed on Main thread.
| Returns || |-----------|-----------------------------------------------------------------------------------------------| | `boolean` | true if the requery succeeded, false if not, in which case the cursor becomes invalid.
| ### setFillWindowForwardOnly Added in[API level 28](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public void setFillWindowForwardOnly (boolean fillWindowForwardOnly) ``` Controls fetching of rows relative to requested position. Calling this method defines how rows will be loaded, but it doesn't affect rows that are already in the window. This setting is preserved if a new window is[set](https://developer.android.com/reference/android/database/sqlite/SQLiteCursor#setWindow(android.database.CursorWindow))
| Parameters || |-------------------------|---------------------------------------------------------------------------------------------------------------------------------------| | `fillWindowForwardOnly` | `boolean`: if true, rows will be fetched starting from requested position up to the window's capacity. Default value is false.
| ### setSelectionArguments Added in[API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public void setSelectionArguments (String[] selectionArgs) ``` Changes the selection arguments. The new values take effect after a call to requery().
| Parameters || |-----------------|-----------------| | `selectionArgs` | `String`
| ### setWindow Added in[API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public void setWindow (CursorWindow window) ``` Sets a new cursor window for the cursor to use. The cursor takes ownership of the provided cursor window; the cursor window will be closed when the cursor is closed or when the cursor adopts a new cursor window. If the cursor previously had a cursor window, then it is closed when the new cursor window is assigned.

| Parameters || |----------|---------------------------------------------------------------------------------| | `window` | `CursorWindow`: The new cursor window, typically a remote cursor window.
| ## Protected methods ### finalize Added in[API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` protected void finalize () ``` Release the native resources, if they haven't been released yet.
