The InputMethod interface represents an input method which can generate key events and text, such as digital, email addresses, CJK characters, other language characters, and etc.

Remarks
The InputMethod interface represents an input method which can generate key events and text, such as digital, email addresses, CJK characters, other language characters, and etc., while handling various input events, and send the text back to the application that requests text input. See InputMethodManager
for more general information about the architecture.
Applications will not normally use this interface themselves, instead relying on the standard interaction provided by android.widget.TextView
and android.widget.EditText
.
Those implementing input methods should normally do so by deriving from InputMethodService
or one of its subclasses. When implementing an input method, the service component containing it must also supply a #SERVICE_META_DATA
meta-data field, referencing an XML resource providing details about the input method. All input methods also must require that clients hold the android.Manifest.permission#BIND_INPUT_METHOD
in order to interact with the service; if this is not required, the system will not use that input method, because it can not trust that it is not compromised.
The InputMethod interface is actually split into two parts: the interface here is the top-level interface to the input method, providing all access to it, which only the system can access (due to the BIND_INPUT_METHOD permission requirement). In addition its method #createSession(android.view.inputmethod.InputMethod.SessionCallback)
can be called to instantate a secondary InputMethodSession
interface which is what clients use to communicate with the input method.

Fields
ServiceInterface |
This is the interface name that a service implementing an input method should say that it supports -- that is, this is the action it uses for its intent filter. |
ServiceMetaData |
Name under which an InputMethod service component publishes information about itself. |
Properties
Handle |
Gets the JNI value of the underlying Android object. (Inherited from IJavaObject) |
JniIdentityHashCode |
Returns the value of |
JniManagedPeerState |
State of the managed peer. (Inherited from IJavaPeerable) |
JniPeerMembers |
Member access and invocation support. (Inherited from IJavaPeerable) |
PeerReference |
Returns a JniObjectReference of the wrapped Java object instance. (Inherited from IJavaPeerable) |
Methods
AttachToken(IBinder) |
Called first thing after an input method is created, this supplies a unique token for the session it has with the system service. |
BindInput(InputBinding) |
Bind a new application environment in to the input method, so that it can later start and stop input processing. |
ChangeInputMethodSubtype(InputMethodSubtype) |
Notify that the input method subtype is being changed in the same input method. |
CreateSession(IInputMethodSessionCallback) |
Create a new |
Disposed() |
Called when the instance has been disposed. (Inherited from IJavaPeerable) |
DisposeUnlessReferenced() |
If there are no outstanding references to this instance, then
calls |
Finalized() |
Called when the instance has been finalized. (Inherited from IJavaPeerable) |
HideSoftInput(Int32, ResultReceiver) |
Request that any soft input part of the input method be hidden from the user. |
RestartInput(IInputConnection, EditorInfo) |
This method is called when the state of this input method needs to be reset. |
RevokeSession(IInputMethodSession) |
Disable and destroy a session that was previously created with
|
SetJniIdentityHashCode(Int32) |
Set the value returned by |
SetJniManagedPeerState(JniManagedPeerStates) | (Inherited from IJavaPeerable) |
SetPeerReference(JniObjectReference) |
Set the value returned by |
SetSessionEnabled(IInputMethodSession, Boolean) |
Control whether a particular input method session is active. |
ShowSoftInput(ShowSoftInputFlags, ResultReceiver) |
Request that any soft input part of the input method be shown to the user. |
StartInput(IInputConnection, EditorInfo) |
This method is called when the application starts to receive text and it is ready for this input method to process received events and send result text back to the application. |
UnbindInput() |
Unbind an application environment, called when the information previously
set by |
UnregisterFromRuntime() |
Unregister this instance so that the runtime will not return it from future Java.Interop.JniRuntime+JniValueManager.PeekValue invocations. (Inherited from IJavaPeerable) |
