Class SessionTextInput

Object
org.mozilla.geckoview.SessionTextInput
public final class SessionTextInput extends Object
SessionTextInput handles text input for GeckoSession through key events or input methods. It is typically used to implement certain methods in View such as View.onCreateInputConnection(android.view.inputmethod.EditorInfo), by forwarding such calls to corresponding methods in SessionTextInput.

For full functionality, SessionTextInput requires a View to be set first through setView(android.view.View). When a View is not set or set to null, SessionTextInput will operate in a reduced functionality mode. See onCreateInputConnection(android.view.inputmethod.EditorInfo) and methods in GeckoSession.TextInputDelegate for changes in behavior in this viewless mode.

  • Method Details

    • getHandler

      @AnyThread @NonNull public Handler getHandler(@NonNull Handler defHandler)
      Get a Handler for the background input method thread.
      Parameters:
      defHandler - Handler returned by the system getHandler implementation.

      Handler to return to the system through getHandler.

    • getView

      @UiThread @Nullable public View getView()
      Get the current View for text input.
      Returns:

    • setView

      @UiThread public void setView(@Nullable View view)
      Set the current View for text input. The View is used to interact with the system input method manager and to display certain text input UI elements. See the SessionTextInput class documentation for information on viewless mode, when the current View is not set or set to null.
      Parameters:
      view - Text input View or null to clear current View.

    • onCreateInputConnection

      @AnyThread @Nullable public InputConnection onCreateInputConnection(@NonNull EditorInfo attrs)
      Get an InputConnection instance. In viewless mode, this method still fills out the EditorInfo object, but the return value will always be null.
      Parameters:
      attrs - EditorInfo instance to be filled on return.
      Returns:
      InputConnection instance, or null if there is no active input (or if in viewless mode).
