This is typically usedwhen composing a message.Corresponds to{link android.view.inputmethod.EditorInfo#IME_ACTION_SEND}. –flag nameactionSend value0x00000004 /!– The action key performs a nextoperation, taking the user to the next field that will accept text.Corresponds to{link android.view.inputmethod.EditorInfo#IME_ACTION_NEXT}. –flag nameactionNext value0x00000005 /!– The action key performs a doneoperation, closing the soft input method.Corresponds to{link android.view.inputmethod.EditorInfo#IME_ACTION_DONE}. –flag nameactionDone value0x00000006 /!– The action key performs a previousoperation, taking the user to the previous field that will accept text.Corresponds to{link android.view.inputmethod.EditorInfo#IME_ACTION_PREVIOUS}. –flag nameactionPrevious value0x00000007 /!– Used to request that the IME should not update any personalized data such as typinghistory and personalized language model based on what the user typed on this textediting object. Typical use cases are:ulliWhen the application is in a special mode, where users activities are expectedto be not recorded in the applications history. Some web browsers and chatapplications may have this kind of modes./liliWhen storing typing history does not make much sense. Specifying this flag intyping games may help to avoid typing history from being filled up with words thatthe user is less likely to type in their daily life. Another example is that whenthe application already knows that the expected input is not a valid word (e.g. apromotion code that is not a valid word in any natural language)./li/ulpApplications need to be aware that the flag is not a guarantee, and some IMEs maynot respect it./p –flag nameflagNoPersonalizedLearning value0x1000000 /!– Used to request that the IME never gointo fullscreen mode. Applications need to be aware that the flag is nota guarantee, and not all IMEs will respect it.pCorresponds to{link android.view.inputmethod.EditorInfo#IME_FLAG_NO_FULLSCREEN}. –flag nameflagNoFullscreen value0x2000000 /!– Like flagNavigateNext, butspecifies there is something interesting that a backward navigationcan focus on. If the user selects the IMEs facility to backwardnavigate, this will show up in the application as an actionPreviousat {link android.view.inputmethod.InputConnection#performEditorAction(int)InputConnection.performEditorAction(int)}.pCorresponds to{link android.view.inputmethod.EditorInfo#IME_FLAG_NAVIGATE_PREVIOUS}. –flag nameflagNavigatePrevious value0x4000000 /!– Used to specify that there is somethinginteresting that a forward navigation can focus on. This is like usingactionNext, except allows the IME to be multiline (withan enter key) as well as provide forward navigation. Note that someIMEs may not be able to do this, especially when running on a smallscreen where there is little space. In that case it does not need topresent a UI for this option. Like actionNext, if theuser selects the IMEs facility to forward navigate, this will show upin the application at{link android.view.inputmethod.InputConnection#performEditorAction(int)InputConnection.performEditorAction(int)}.pCorresponds to{link android.view.inputmethod.EditorInfo#IME_FLAG_NAVIGATE_NEXT}. –flag nameflagNavigateNext value0x8000000 /!– Used to specify that the IME does not needto show its extracted text UI. For input methods that may be fullscreen,often when in landscape mode, this allows them to be smaller and let partof the application be shown behind. Though there will likely be limitedaccess to the application available from the user, it can make theexperience of a (mostly) fullscreen IME less jarring. Note that whenthis flag is specified the IME may emnot/em be set up to be ableto display text, so it should only be used in situations where this isnot needed.pCorresponds to{link android.view.inputmethod.EditorInfo#IME_FLAG_NO_EXTRACT_UI}. –flag nameflagNoExtractUi value0x10000000 /!– Used in conjunction with a custom action, this indicates that theaction should not be available as an accessory button when theinput method is full-screen.Note that by setting this flag, there can be cases where the actionis simply never available to the user. Setting this generally meansthat you think showing text being edited is more important than theaction you have supplied.pCorresponds to{link android.view.inputmethod.EditorInfo#IME_FLAG_NO_ACCESSORY_ACTION}. –flag nameflagNoAccessoryAction value0x20000000 /!– Used in conjunction with a custom action,this indicates that the action should not be available in-line asa replacement for the enter key. Typically this isbecause the action has such a significant impact or is not recoverableenough that accidentally hitting it should be avoided, such as sendinga message. Note that {link android.widget.TextView} willautomatically set this flag for you on multi-line text views.pCorresponds to{link android.view.inputmethod.EditorInfo#IME_FLAG_NO_ENTER_ACTION}. –flag nameflagNoEnterAction value0x40000000 /!– Used to request that the IME should be capable of inputting ASCIIcharacters. The intention of this flag is to ensure that the usercan type Roman alphabet characters in a {link android.widget.TextView}used for, typically, account ID or password input. It is expected that IMEsnormally are able to input ASCII even without being told so (such IMEsalready respect this flag in a sense), but there could be some cases theyarent when, for instance, only non-ASCII input languages like Arabic,Greek, Hebrew, Russian are enabled in the IME. Applications need to beaware that the flag is not a guarantee, and not all IMEs will respect it.However, it is strongly recommended for IME authors to respect this flagespecially when their IME could end up with a state that has only non-ASCIIinput languages enabled.pCorresponds to{link android.view.inputmethod.EditorInfo#IME_FLAG_FORCE_ASCII}. –flag nameflagForceAscii value0x80000000 //attr2.2 继承InputMethodService.java的输入法应用覆盖onEvaluateFullscreenMode方法 覆盖onEvaluateFullscreenMode方法返false就可以了。如Android14上google输入法LatinImeGoogle.apk frameworks/base/core/java/android/inputmethodservice/InputMethodService.java /** Override this to control when the input method should run in* fullscreen mode.
