InputMethodManager
extends Object

↳ | android.view.inputmethod.InputMethodManager |
Central system API to the overall input method framework (IMF) architecture,
which arbitrates interaction between applications and the current input method.
You can retrieve an instance of this interface with
Context.getSystemService()
.
Topics covered here:
There are three primary parties involved in the input method framework (IMF) architecture:
In most cases, applications that are using the standard
TextView
or its subclasses will have little they need
to do to work well with soft input methods. The main things you need to
be aware of are:
inputType
in your editable
text views, so that the input method will have enough context to help the
user in entering text into them.
windowSoftInputMode
attribute on your activity or the corresponding values on windows you
create to help the system determine whether to pan or resize (it will
try to determine this automatically but may get it wrong).
windowSoftInputMode
attribute.
More finer-grained control is available through the APIs here to directly interact with the IMF and its IME -- either showing or hiding the input area, letting the user pick an input method, etc.
For the rare people amongst us writing their own text editors, you
will need to implement onCreateInputConnection(EditorInfo)
to return a new instance of your own InputConnection
interface
allowing the IME to interact with your editor.
An input method (IME) is implemented
as a Service
, typically deriving from
InputMethodService
. It must provide
the core InputMethod
interface, though this is normally handled by
InputMethodService
and implementors will
only need to deal with the higher-level API there.
InputMethodService
class for
more information on implementing IMEs.
There are a lot of security issues associated with input methods, since they essentially have freedom to completely drive the UI and monitor everything the user enters. The Android input method framework also allows arbitrary third party IMEs, so care must be taken to restrict their selection and interactions.
Here are some key points about the security architecture behind the IMF:
Only the system is allowed to directly access an IME's
InputMethod
interface, via the
BIND_INPUT_METHOD
permission. This is
enforced in the system by not binding to an input method service that does
not require this permission, so the system can guarantee no other untrusted
clients are accessing the current input method outside of its control.
There may be many client processes of the IMF, but only one may be active at a time. The inactive clients can not interact with key parts of the IMF through the mechanisms described below.
Clients of an input method are only given access to its
InputMethodSession
interface. One instance of this interface is
created for each client, and only calls from the session associated with
the active client will be processed by the current IME. This is enforced
by AbstractInputMethodService
for normal
IMEs, but must be explicitly handled by an IME that is customizing the
raw InputMethodSession
implementation.
Only the active client's InputConnection
will accept
operations. The IMF tells each client process whether it is active, and
the framework enforces that in inactive processes calls on to the current
InputConnection will be ignored. This ensures that the current IME can
only deliver events and text edits to the UI that the user sees as
being in focus.
An IME can never interact with an InputConnection
while
the screen is off. This is enforced by making all clients inactive while
the screen is off, and prevents bad IMEs from driving the UI when the user
can not be aware of its behavior.
A client application can ask that the system let the user pick a new IME, but can not programmatically switch to one itself. This avoids malicious applications from switching the user to their own IME, which remains running when the user navigates away to another application. An IME, on the other hand, is allowed to programmatically switch the system to another IME, since it already has full control of user input.
The user must explicitly enable a new IME in settings before they can switch to it, to confirm with the system that they know about it and want to make it available for use.

boolean hideSoftInputFromWindow (IBinder windowToken, int flags, ResultReceiver resultReceiver)
Request to hide the soft input window from the context of the window that is currently accepting input. This should be called as a result of the user doing some actually than fairly explicitly requests to have the input window hidden.
Caveat: ResultReceiver
instance passed to
this method can be a long-lived object, because it may not be
garbage-collected until all the corresponding ResultReceiver
objects transferred to different processes get garbage-collected.
Follow the general patterns to avoid memory leaks in Android.
Consider to use WeakReference
so that application
logic objects such as Activity
and Context
can be garbage collected regardless of the lifetime of
ResultReceiver
.

void restartInput (View view)
If the input method is currently connected to the given view, restart it with its new contents. You should call this when the text within your view changes outside of the normal input method or key input flow, such as when an application calls TextView.setText().
Parameters | |
---|---|
view |
View :
The view whose text has changed.
|
void sendAppPrivateCommand (View view, String action, Bundle data)
Call InputMethodSession.appPrivateCommand()
on the current Input Method.
Parameters | |
---|---|
view |
View :
Optional View that is sending the command, or null if
you want to send the command regardless of the view that is attached
to the input method. |
action |
String :
Name of the command to be performed. This must
be a scoped name, i.e. prefixed with a package name you own, so that
different developers will not create conflicting commands. |
data |
Bundle :
Any data to include with the command.
|
void setAdditionalInputMethodSubtypes (String imiId, InputMethodSubtype[] subtypes)
Set additional input method subtypes. Only a process which shares the same uid with the IME
can add additional input method subtypes to the IME.
Please note that a subtype's status is stored in the system.
For example, enabled subtypes are remembered by the framework even after they are removed
by using this method. If you re-add the same subtypes again,
they will just get enabled. If you want to avoid such conflicts, for instance, you may
want to create a "different" new subtype even with the same locale and mode,
by changing its extra value. The different subtype won't get affected by the stored past
status. (You may want to take a look at hashCode()
to refer
to the current implementation.)
NOTE: If the same subtype exists in both the manifest XML file and additional subtypes
specified by subtypes
, those multiple instances are automatically merged into one
instance.
CAVEAT: In API Level 23 and prior, the system may do nothing if an empty
InputMethodSubtype
is specified in subtypes
, which prevents you from removing
the last one entry of additional subtypes. If your IME statically defines one or more
subtypes in the manifest XML file, you may be able to work around this limitation by
specifying one of those statically defined subtypes in subtypes
.
Parameters | |
---|---|
imiId |
String :
Id of InputMethodInfo which additional input method subtypes will be added to. |
subtypes |
InputMethodSubtype :
subtypes will be added as additional subtypes of the current input method.
|
boolean setCurrentInputMethodSubtype (InputMethodSubtype subtype)
Switch to a new input method subtype of the current input method.
Parameters | |
---|---|
subtype |
InputMethodSubtype :
A new input method subtype to switch. |
Returns | |
---|---|
boolean |
true if the current subtype was successfully switched. When the specified subtype is null, this method returns false. |
void setInputMethod (IBinder token, String id)
Force switch to a new input method component. This can only be called from an application or a service which has a token of the currently active input method.
Parameters | |
---|---|
token |
IBinder :
Supplies the identifying token given to an input method
when it was started, which allows it to perform this operation on
itself. |
id |
String :
The unique identifier for the new input method to be switched to.
|
void setInputMethodAndSubtype (IBinder token, String id, InputMethodSubtype subtype)
Force switch to a new input method and subtype. This can only be called from an application or a service which has a token of the currently active input method.

The new subtype of the new input method to be switched to.
|
boolean shouldOfferSwitchingToNextInputMethod (IBinder imeToken)
Returns true if the current IME needs to offer the users ways to switch to a next input
method (e.g. a globe key.).
When an IME sets supportsSwitchingToNextInputMethod and this method returns true,
the IME has to offer ways to to invoke switchToNextInputMethod(IBinder, boolean)
accordingly.
Note that the system determines the most appropriate next input method and subtype in order to provide the consistent user experience in switching between IMEs and subtypes.
