SoftKeyboardController
class SoftKeyboardController
| kotlin.Any | |
| ↳ | android.accessibilityservice.AccessibilityService.SoftKeyboardController |
Used to control, query, and listen for changes to the soft keyboard show mode.
Accessibility services may request to override the decisions normally made about whether or not the soft keyboard is shown.
If multiple services make conflicting requests, the last request is honored. A service may register a listener to find out if the mode has changed under it.
If the user takes action to override the behavior behavior requested by an accessibility service, the user's request takes precendence, the show mode will be reset to AccessibilityService#SHOW_MODE_AUTO, and services will no longer be able to control that aspect of the soft keyboard's behavior.
Note: Because soft keyboards are independent apps, the framework does not have total control over their behavior. They may choose to show themselves, or not, without regard to requests made here. So the framework will make a best effort to deliver the behavior requested, but cannot guarantee success.

Constants
ENABLE_IME_FAIL_BY_ADMIN
static val ENABLE_IME_FAIL_BY_ADMIN: Int
Return value for setInputMethodEnabled(java.lang.String,boolean). The action failed because the InputMethod is not permitted by device policy manager.
Value: 1
ENABLE_IME_FAIL_UNKNOWN
static val ENABLE_IME_FAIL_UNKNOWN: Int
Return value for setInputMethodEnabled(java.lang.String,boolean). The action failed and the reason is unknown.
Value: 2
ENABLE_IME_SUCCESS
static val ENABLE_IME_SUCCESS: Int
Return value for setInputMethodEnabled(java.lang.String,boolean). The action succeeded.
Value: 0
Public methods
addOnShowModeChangedListener
fun addOnShowModeChangedListener(listener: AccessibilityService.SoftKeyboardController.OnShowModeChangedListener): Unit
Adds the specified change listener to the list of show mode change listeners. The callback will occur on the service's main thread. Listener is not called on registration.
| Parameters | |
|---|---|
listener |
AccessibilityService.SoftKeyboardController.OnShowModeChangedListener: This value cannot be null. |
addOnShowModeChangedListener
fun addOnShowModeChangedListener(
listener: AccessibilityService.SoftKeyboardController.OnShowModeChangedListener,
handler: Handler?
): Unit
Adds the specified change listener to the list of soft keyboard show mode change listeners. The callback will occur on the specified Handler's thread, or on the services's main thread if the handler is null.
| Parameters | |
|---|---|
listener |
AccessibilityService.SoftKeyboardController.OnShowModeChangedListener: the listener to add, must be non-null |
handler |
Handler?: the handler on which to callback should execute, or null to execute on the service's main thread |
getShowMode
fun getShowMode(): Int
Returns the show mode of the soft keyboard.
| Return | |
|---|---|
Int |
the current soft keyboard show mode Value is android.accessibilityservice.AccessibilityService#SHOW_MODE_AUTO, android.accessibilityservice.AccessibilityService#SHOW_MODE_HIDDEN, or android.accessibilityservice.AccessibilityService#SHOW_MODE_IGNORE_HARD_KEYBOARD |
removeOnShowModeChangedListener
fun removeOnShowModeChangedListener(listener: AccessibilityService.SoftKeyboardController.OnShowModeChangedListener): Boolean
Removes the specified change listener from the list of keyboard show mode change listeners.
| Parameters | |
|---|---|
listener |
AccessibilityService.SoftKeyboardController.OnShowModeChangedListener: the listener to remove, must be non-null |
| Return | |
|---|---|
Boolean |
true if the listener was removed, false otherwise |
setInputMethodEnabled
fun setInputMethodEnabled(
imeId: String,
enabled: Boolean
): Int
Enable or disable the specified IME for the user for whom the service is activated. The IME needs to be in the same package as the service and needs to be allowed by device policy, if there is one. The change will persist until the specified IME is next explicitly enabled or disabled by whatever means, such as user choice, and may persist beyond the life cycle of the requesting service.
| Parameters | |
|---|---|
imeId |
String: The ID of the input method to enable or disable. This IME must be installed. This value cannot be null. |
enabled |
Boolean: true if the input method associated with imeId should be enabled. |
| Return | |
|---|---|
Int |
status code for the result of enabling/disabling the input method associated with imeId. Value is android.accessibilityservice.AccessibilityService.SoftKeyboardController#ENABLE_IME_SUCCESS, android.accessibilityservice.AccessibilityService.SoftKeyboardController#ENABLE_IME_FAIL_BY_ADMIN, or android.accessibilityservice.AccessibilityService.SoftKeyboardController#ENABLE_IME_FAIL_UNKNOWN |
| Exceptions | |
|---|---|
java.lang.SecurityException |
if the input method is not in the same package as the service. |
setShowMode
fun setShowMode(showMode: Int): Boolean
Sets the soft keyboard show mode.
Note: If the service is not yet connected (e.g. AccessibilityService#onServiceConnected() has not yet been called) or the service has been disconnected, this method will have no effect and return false.
| Parameters | |
|---|---|
showMode |
Int: the new show mode for the soft keyboard Value is android.accessibilityservice.AccessibilityService#SHOW_MODE_AUTO, android.accessibilityservice.AccessibilityService#SHOW_MODE_HIDDEN, or android.accessibilityservice.AccessibilityService#SHOW_MODE_IGNORE_HARD_KEYBOARD |
| Return | |
|---|---|
Boolean |
true on success |
switchToInputMethod
fun switchToInputMethod(imeId: String): Boolean
Switches the current IME for the user for whom the service is enabled. The change will persist until the current IME is explicitly changed again, and may persist beyond the life cycle of the requesting service.
| Parameters | |
|---|---|
imeId |
String: The ID of the input method to make current. This IME must be installed and enabled. This value cannot be null. |
| Return | |
|---|---|
Boolean |
true if the current input method was successfully switched to the input method by imeId, false if the input method specified is not installed, not enabled, or otherwise not available to become the current IME |
