Known direct subclasses

InputMethodService.InputMethodSessionImpl

InputMethodService.InputMethodSessionImpl Concrete implementation of AbstractInputMethodService.AbstractInputMethodSessionImpl that provides all of the standard behavior for an input method session.

Base class for derived classes to implement their InputMethodSession interface. This takes care of basic maintenance of the session, but most behavior must be implemented in a derived class.

Summary

Inherited methods

From class


        
          java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long timeoutMillis, int nanos)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait(long timeoutMillis)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait()` Causes the current thread to wait until it is awakened, typically by being notified or interrupted.

From interface


        
          android.view.inputmethod.InputMethodSession

`abstract void`	`appPrivateCommand(String action, Bundle data)` Process a private command sent from the application to the input method.
`abstract void`	`dispatchGenericMotionEvent(int seq, MotionEvent event, InputMethodSession.EventCallback callback)` This method is called when there is a generic motion event.
`abstract void`	`dispatchKeyEvent(int seq, KeyEvent event, InputMethodSession.EventCallback callback)` This method is called when a key is pressed.
`abstract void`	`dispatchTrackballEvent(int seq, MotionEvent event, InputMethodSession.EventCallback callback)` This method is called when there is a track ball event.
`abstract void`	`displayCompletions(CompletionInfo[] completions)` Called by a text editor that performs auto completion, to tell the input method about the completions it has available.
`abstract void`	`finishInput()` This method is called when the application would like to stop receiving text input.
`abstract void`	`toggleSoftInput(int showFlags, int hideFlags)` This method was deprecated in API level 31. Starting in `Build.VERSION_CODES.S` the system no longer invokes this method, instead it explicitly shows or hides the IME. An `InputMethodService` wishing to toggle its own visibility should instead invoke `InputMethodService.requestShowSelf(int)` or `InputMethodService.requestHideSelf`
`abstract void`	`updateCursor(Rect newCursor)` This method is called when cursor location of the target input field has changed within its window.
`abstract void`	`updateCursorAnchorInfo(CursorAnchorInfo cursorAnchorInfo)` This method is called when the cursor and/or the character position relevant to text input is changed on the screen.
`abstract void`	`updateExtractedText(int token, ExtractedText text)` Called by a text editor to report its new extracted text when its contents change.
`abstract void`	`updateSelection(int oldSelStart, int oldSelEnd, int newSelStart, int newSelEnd, int candidatesStart, int candidatesEnd)` This method is called when the selection or cursor in the current target input field has changed.
`abstract void`	`viewClicked(boolean focusChanged)` This method is called when the user tapped a text view.

Public methods

dispatchGenericMotionEvent

Added in API level 17

public void dispatchGenericMotionEvent (int seq, 
                MotionEvent event, 
                InputMethodSession.EventCallback callback)

Take care of dispatching incoming generic motion events to the appropriate callbacks on the service, and tell the client when this is done.

Parameters
`seq`	`int`
`event`	`MotionEvent`: The motion event.
`callback`	`InputMethodSession.EventCallback`

Returns
`void`	Whether the input method wants to handle this event.

dispatchKeyEvent

Added in API level 3

public void dispatchKeyEvent (int seq, 
                KeyEvent event, 
                InputMethodSession.EventCallback callback)

Take care of dispatching incoming key events to the appropriate callbacks on the service, and tell the client when this is done.

Parameters
`seq`	`int`
`event`	`KeyEvent`: The key event.
`callback`	`InputMethodSession.EventCallback`

Returns
`void`	Whether the input method wants to handle this event.

dispatchTrackballEvent

Added in API level 3

public void dispatchTrackballEvent (int seq, 
                MotionEvent event, 
                InputMethodSession.EventCallback callback)

Take care of dispatching incoming trackball events to the appropriate callbacks on the service, and tell the client when this is done.

Parameters
`seq`	`int`
`event`	`MotionEvent`: The motion event.
`callback`	`InputMethodSession.EventCallback`

Returns
`void`	Whether the input method wants to handle this event.

isEnabled

Added in API level 3

public boolean isEnabled ()

Check whether this session has been enabled by the system. If not enabled, you should not execute any calls on to it.

Returns
`boolean`

isRevoked

Added in API level 3

public boolean isRevoked ()

Check whether this session has been revoked by the system. Revoked session is also always disabled, so there is generally no need to explicitly check for this.

Returns
`boolean`

revokeSelf

Added in API level 3

public void revokeSelf ()

Revoke the session from the client. This disabled the session, and prevents it from ever being enabled again.

setEnabled

Added in API level 3

public void setEnabled (boolean enabled)

Change the enabled state of the session. This only works if the session has not been revoked.

Parameters
`enabled`	`boolean`
