[<Android.Runtime.Register("deleteSurroundingTextInCodePoints", "(II)Z", "GetDeleteSurroundingTextInCodePoints_IIHandler:Android.Views.InputMethods.IInputConnectionInvoker, Mono.Android, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null", ApiSince=24)>]
abstract member DeleteSurroundingTextInCodePoints : int * int -> bool

Parameters

beforeLength: Int32

The number of characters before the cursor to be deleted, in code points. If this is greater than the number of existing characters between the beginning of the text and the cursor, then this method does not fail but deletes all the characters in that range.

afterLength: Int32

The number of characters after the cursor to be deleted, in code points. If this is greater than the number of existing characters between the cursor and the end of the text, then this method does not fail but deletes all the characters in that range.

Returns

Boolean

true on success, false if the input connection is no longer valid. Before Android android.os.Build.VERSION_CODES#TIRAMISU, this API returned false when the target application does not implement this method.

Attributes: RegisterAttribute

Remarks

A variant of #deleteSurroundingText(int, int). Major differences are:

<ul> <li>The lengths are supplied in code points, not in Java chars or in glyphs.</> <li>This method does nothing if there are one or more invalid surrogate pairs in the requested range.</li> </ul>

<strong>Editor authors:</strong> In addition to the requirement in #deleteSurroundingText(int, int), make sure to do nothing when one ore more invalid surrogate pairs are found in the requested range.
