InputMethodSubtype

extends Object
implements Parcelable
java.lang.Object
   ↳ android.view.inputmethod.InputMethodSubtype

Class Overview

This class is used to specify meta information of a subtype contained in an input method editor (IME). Subtype can describe locale (e.g. en_US, fr_FR...) and mode (e.g. voice, keyboard...), and is used for IME switch and settings. The input method subtype allows the system to bring up the specified subtype of the designated IME directly.

It should be defined in an XML resource file of the input method with the <subtype> element. For more information, see the guide to Creating an Input Method.

public static final Creator<InputMethodSubtype> CREATOR

Added in API level 11

Public Constructors

public InputMethodSubtype (int nameId, int iconId, String locale, String mode, String extraValue, boolean isAuxiliary, boolean overridesImplicitlyEnabledSubtype)

Added in API level 14

Constructor with no subtype ID specified.

Parameters
nameId Resource ID of the subtype name string. The string resource may have exactly one %s in it. If there is, the %s part will be replaced with the locale's display name by the formatter. Please refer to getDisplayName(Context, String, ApplicationInfo) for details.
iconId Resource ID of the subtype icon drawable.
locale The locale supported by the subtype
mode The mode supported by the subtype
extraValue The extra value of the subtype. This string is free-form, but the API supplies tools to deal with a key-value comma-separated list; see containsExtraValueKey(String) and getExtraValueOf(String).
isAuxiliary true when this subtype is auxiliary, false otherwise. An auxiliary subtype will not be shown in the list of enabled IMEs for choosing the current IME in the Settings even when this subtype is enabled. Please note that this subtype will still be shown in the list of IMEs in the IME switcher to allow the user to tentatively switch to this subtype while an IME is shown. The framework will never switch the current IME to this subtype by switchToLastInputMethod(IBinder). The intent of having this flag is to allow for IMEs that are invoked in a one-shot way as auxiliary input mode, and return to the previous IME once it is finished (e.g. voice input).
overridesImplicitlyEnabledSubtype true when this subtype should be enabled by default if no other subtypes in the IME are enabled explicitly. Note that a subtype with this parameter being true will not be shown in the list of subtypes in each IME's subtype enabler. Having an "automatic" subtype is an example use of this flag.

public InputMethodSubtype (int nameId, int iconId, String locale, String mode, String extraValue, boolean isAuxiliary, boolean overridesImplicitlyEnabledSubtype, int id)

Added in API level 17

Constructor.

Parameters
nameId Resource ID of the subtype name string. The string resource may have exactly one %s in it. If there is, the %s part will be replaced with the locale's display name by the formatter. Please refer to getDisplayName(Context, String, ApplicationInfo) for details.
iconId Resource ID of the subtype icon drawable.
locale The locale supported by the subtype
mode The mode supported by the subtype
extraValue The extra value of the subtype. This string is free-form, but the API supplies tools to deal with a key-value comma-separated list; see containsExtraValueKey(String) and getExtraValueOf(String).
isAuxiliary true when this subtype is auxiliary, false otherwise. An auxiliary subtype will not be shown in the list of enabled IMEs for choosing the current IME in the Settings even when this subtype is enabled. Please note that this subtype will still be shown in the list of IMEs in the IME switcher to allow the user to tentatively switch to this subtype while an IME is shown. The framework will never switch the current IME to this subtype by switchToLastInputMethod(IBinder). The intent of having this flag is to allow for IMEs that are invoked in a one-shot way as auxiliary input mode, and return to the previous IME once it is finished (e.g. voice input).
overridesImplicitlyEnabledSubtype true when this subtype should be enabled by default if no other subtypes in the IME are enabled explicitly. Note that a subtype with this parameter being true will not be shown in the list of subtypes in each IME's subtype enabler. Having an "automatic" subtype is an example use of this flag.
id The unique ID for the subtype. The input method framework keeps track of enabled subtypes by ID. When the IME package gets upgraded, enabled IDs will stay enabled even if other attributes are different. If the ID is unspecified or 0, Arrays.hashCode(new Object[] {locale, mode, extraValue, isAuxiliary, overridesImplicitlyEnabledSubtype}) will be used instead.

Public Methods

public boolean containsExtraValueKey (String key)

Added in API level 12

The string of ExtraValue in subtype should be defined as follows: example: key0,key1=value1,key2,key3,key4=value4

Parameters
key The key of extra value
Returns
  • The subtype contains specified the extra value

public int describeContents ()

Added in API level 11

Describe the kinds of special objects contained in this Parcelable's marshalled representation.

Returns
  • a bitmask indicating the set of special object types marshalled by the Parcelable.

public boolean equals (Object o)

Added in API level 11

Compares this instance with the specified object and indicates if they are equal. In order to be equal, o must represent the same object as this instance using a class-specific comparison. The general contract is that this comparison should be reflexive, symmetric, and transitive. Also, no object reference other than null is equal to null.

The default implementation returns true only if this == o. See Writing a correct equals method if you intend implementing your own equals method.

The general contract for the equals and hashCode() methods is that if equals returns true for any two objects, then hashCode() must return the same value for these objects. This means that subclasses of Object usually override either both methods or neither of them.

Parameters
o the object to compare this instance with.
Returns
  • true if the specified object is equal to this Object; false otherwise.

public CharSequence getDisplayName (Context context, String packageName, ApplicationInfo appInfo)

Added in API level 14

Parameters
context Context will be used for getting Locale and PackageManager.
packageName The package name of the IME
appInfo The application info of the IME
Returns
  • a display name for this subtype. The string resource of the label (mSubtypeNameResId) may have exactly one %s in it. If there is, the %s part will be replaced with the locale's display name by the formatter. If there is not, this method returns the string specified by mSubtypeNameResId. If mSubtypeNameResId is not specified (== 0), it's up to the framework to generate an appropriate display name.

public String getExtraValue ()

Added in API level 11

Returns
  • The extra value of the subtype.

public String getExtraValueOf (String key)

Added in API level 12

The string of ExtraValue in subtype should be defined as follows: example: key0,key1=value1,key2,key3,key4=value4

Parameters
key The key of extra value
Returns
  • The value of the specified key

public int getIconResId ()

Added in API level 11

Returns
  • Resource ID of the subtype icon drawable.

public String getLocale ()

Added in API level 11

Returns
  • The locale of the subtype. This method returns the "locale" string parameter passed to the constructor.

public String getMode ()

Added in API level 11

Returns
  • The mode of the subtype.

public int getNameResId ()

Added in API level 11

Returns
  • Resource ID of the subtype name string.

public int hashCode ()

Added in API level 11

Returns an integer hash code for this object. By contract, any two objects for which equals(Object) returns true must return the same hash code value. This means that subclasses of Object usually override both methods or neither method.

Note that hash values must not change over time unless information used in equals comparisons also changes.

See Writing a correct hashCode method if you intend implementing your own hashCode method.

Returns
  • this object's hash code.

public boolean isAuxiliary ()

Added in API level 14

Returns
  • true if this subtype is auxiliary, false otherwise. An auxiliary subtype will not be shown in the list of enabled IMEs for choosing the current IME in the Settings even when this subtype is enabled. Please note that this subtype will still be shown in the list of IMEs in the IME switcher to allow the user to tentatively switch to this subtype while an IME is shown. The framework will never switch the current IME to this subtype by switchToLastInputMethod(IBinder). The intent of having this flag is to allow for IMEs that are invoked in a one-shot way as auxiliary input mode, and return to the previous IME once it is finished (e.g. voice input).

public boolean overridesImplicitlyEnabledSubtype ()

Added in API level 14

Returns
  • true when this subtype will be enabled by default if no other subtypes in the IME are enabled explicitly, false otherwise. Note that a subtype with this method returning true will not be shown in the list of subtypes in each IME's subtype enabler. Having an "automatic" subtype is an example use of this flag.

public void writeToParcel (Parcel dest, int parcelableFlags)

Added in API level 11

Flatten this object in to a Parcel.

Parameters
dest The Parcel in which the object should be written.
parcelableFlags Additional flags about how the object should be written. May be 0 or PARCELABLE_WRITE_RETURN_VALUE.
