SpellCheckerSubtype


public final class SpellCheckerSubtype
extends Object implements Parcelable

java.lang.Object
   ↳ android.view.textservice.SpellCheckerSubtype


This class is used to specify meta information of a subtype contained in a spell checker. Subtype can describe locale (e.g. en_US, fr_FR...) used for settings.

Public constructors

SpellCheckerSubtype(int nameId, String locale, String extraValue)

This constructor is deprecated. There is no public API that requires developers to directly instantiate custom SpellCheckerSubtype objects right now. Hence only the system is expected to be able to instantiate SpellCheckerSubtype object.

Public methods

boolean containsExtraValueKey(String key)

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

int describeContents()

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

boolean equals(Object o)

Indicates whether some other object is "equal to" this one.

CharSequence getDisplayName(Context context, String packageName, ApplicationInfo appInfo)
String getExtraValue()
String getExtraValueOf(String key)

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

String getLanguageTag()
String getLocale()

This method was deprecated in API level 24. Use getLanguageTag() instead.

int getNameResId()
int hashCode()

Returns a hash code value for the object.

void writeToParcel(Parcel dest, int parcelableFlags)

Flatten this object in to a Parcel.

Inherited methods

XML attributes

android:label

The name of the subtype.

May be a reference to another resource, in the form "@[+][package:]type/name" or a theme attribute in the form "?[package:]type/name".

May be a string value, using '\\;' to escape characters such as '\\n' or '\\uxxxx' for a unicode character;

android:languageTag

The BCP-47 Language Tag of the subtype. This replaces SpellChecker_Subtype_subtypeLocale.

May be a string value, using '\\;' to escape characters such as '\\n' or '\\uxxxx' for a unicode character;

android:subtypeExtraValue

The extra value of the subtype. This string can be any string and will be passed to the SpellChecker.

May be a string value, using '\\;' to escape characters such as '\\n' or '\\uxxxx' for a unicode character;

android:subtypeId

The unique id for the subtype. The text service (spell checker) framework keeps track of enabled subtypes by ID. When the spell checker package gets upgraded, enabled IDs will stay enabled even if other attributes are different. If the ID is unspecified or explicitly specified to 0 in XML resources, Arrays.hashCode(new Object[] {subtypeLocale, extraValue}) will be used instead.

May be an integer value, such as "100".

android:subtypeLocale

The locale of the subtype. This string should be a locale (for example, en_US and fr_FR). This is also used by the framework to know the supported locales of the spell checker. SpellCheckerSubtype.getLocale() returns the value specified in this attribute.

May be a string value, using '\\;' to escape characters such as '\\n' or '\\uxxxx' for a unicode character;

Fields

CREATOR

Added in API level 14
public static final Creator<SpellCheckerSubtype> CREATOR

Public constructors

SpellCheckerSubtype

Added in API level 14
public SpellCheckerSubtype (int nameId, 
                String locale, 
                String extraValue)

This constructor is deprecated.
There is no public API that requires developers to directly instantiate custom SpellCheckerSubtype objects right now. Hence only the system is expected to be able to instantiate SpellCheckerSubtype object.

Constructor.

Parameters
nameId int: The name of the subtype

locale String: The locale supported by the subtype

extraValue String: The extra value of the subtype

Public methods

containsExtraValueKey

Added in API level 16
public boolean containsExtraValueKey (String key)

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

Parameters
key String: the key of extra value

Returns
boolean the subtype contains specified the extra value

describeContents

Added in API level 14
public int describeContents ()

Describe the kinds of special objects contained in this Parcelable instance's marshaled representation. For example, if the object will include a file descriptor in the output of writeToParcel(android.os.Parcel, int), the return value of this method must include the CONTENTS_FILE_DESCRIPTOR bit.

Returns
int a bitmask indicating the set of special object types marshaled by this Parcelable object instance. Value is either 0 or CONTENTS_FILE_DESCRIPTOR

equals

Added in API level 14
public boolean equals (Object o)

Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation on non-null object references:

  • It is reflexive: for any non-null reference value x, x.equals(x) should return true.
  • It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
  • It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
  • It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
  • For any non-null reference value x, x.equals(null) should return false.

An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.

Parameters
o Object: This value may be null.

Returns
boolean true if this object is the same as the obj argument; false otherwise.

getDisplayName

Added in API level 14
public CharSequence getDisplayName (Context context, 
                String packageName, 
                ApplicationInfo appInfo)

Parameters
context Context: Context will be used for getting Locale and PackageManager.

packageName String: The package name of the spell checker

appInfo ApplicationInfo: The application info of the spell checker

Returns
CharSequence a display name for this subtype. The string resource of the label (mSubtypeNameResId) can have only 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 simply returns the string specified by mSubtypeNameResId. If mSubtypeNameResId is not specified (== 0), it's up to the framework to generate an appropriate display name.

getExtraValue

Added in API level 14
public String getExtraValue ()

Returns
String the extra value of the subtype

getExtraValueOf

Added in API level 16
public String getExtraValueOf (String key)

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

Parameters
key String: the key of extra value

Returns
String the value of the specified key

getLanguageTag

Added in API level 24
public String getLanguageTag ()

Returns
String the BCP-47 Language Tag of the subtype. Returns an empty string when no Language Tag is specified. This value cannot be null.

getLocale

Added in API level 14
Deprecated in API level 24
public String getLocale ()

This method was deprecated in API level 24.
Use getLanguageTag() instead.

Returns
String the locale of the subtype This value cannot be null.

getNameResId

Added in API level 14
public int getNameResId ()

Returns
int the name of the subtype

hashCode

Added in API level 14
public int hashCode ()

Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by HashMap.

The general contract of hashCode is:

  • Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
  • If two objects are equal according to the equals method, then calling the hashCode method on each of the two objects must produce the same integer result.
  • It is not required that if two objects are unequal according to the equals method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.

Returns
int a hash code value for this object.

writeToParcel

Added in API level 14
public void writeToParcel (Parcel dest, 
                int parcelableFlags)

Flatten this object in to a Parcel.

Parameters
dest Parcel: The Parcel in which the object should be written. This value cannot be null.

parcelableFlags int: Additional flags about how the object should be written. May be 0 or Parcelable.PARCELABLE_WRITE_RETURN_VALUE. Value is either 0 or a combination of Parcelable.PARCELABLE_WRITE_RETURN_VALUE, and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES
