- Attributes
Remarks
Gets the surrounding text around the current cursor, with <var>beforeLength</var> characters of text before the cursor (start of the selection), <var>afterLength</var> characters of text after the cursor (end of the selection), and all of the selected text. The range are for java characters, not glyphs that can be multiple characters.
This method may fail either if the input connection has become invalid (such as its process crashing), or the client is taking too long to respond with the text (it is given a couple seconds to return), or the protocol is not supported. In any of these cases, null is returned.
This method does not affect the text in the editor in any way, nor does it affect the selection or composing spans.
If InputConnection#GET_TEXT_WITH_STYLES is supplied as flags, the editor should return a android.text.Spanned with all the spans set on the text.
<strong>Accessibility service authors:</strong> please consider this will trigger an IPC round-trip that will take some time. Assume this method consumes a lot of time.
