## XML attributes

### android:configChanges

Specify one or more configuration changes that the IME will handle itself. If not specified, the IME will be restarted if any of these configuration changes happen in the system. Otherwise, the IME will remain running and its `InputMethodService.onConfigurationChanged(Configuration)` method is called with the new configuration.

Note that all of these configuration changes can impact the resource values seen by the application, so you will generally need to re-retrieve all resources (including view layouts, drawables, etc) to correctly handle any configuration change.

Must be one or more (separated by '|') of the following constant values.

Constant | Value | Description
--- | --- | ---
colorMode | 4000 | The color mode of the screen has changed (color gamut or dynamic range).
density | 1000 | The display density has changed. This might be caused by the user specifying a different display scale, or it might be caused by a different display being activated.
fontScale | 40000000 | The font scaling factor has changed, that is the user has selected a new global font size.
fontWeightAdjustment | 10000000 | The font weight adjustment value has changed. Used to reflect the user increasing font weight.
keyboard | 10 | The keyboard type has changed, for example the user has plugged in an external keyboard.
keyboardHidden | 20 | The keyboard or navigation accessibility has changed, for example the user has slid the keyboard out to expose it. Note that despite its name, this applied to any accessibility: keyboard or navigation.
layoutDirection | 2000 | The layout direction has changed. For example going from LTR to RTL.
locale | 4 | The locale has changed, that is the user has selected a new language that text should be displayed in.
mcc | 1 | The IMSI MCC has changed, that is a SIM has been detected and updated the Mobile Country Code. By default from Android O, we don't recreate the activity even the app doesn't specify mcc in configChanges. If the app wants to recreate the activity, specify mcc in recreateOnConfigChanges.
mnc | 2 | The IMSI MNC has changed, that is a SIM has been detected and updated the Mobile Network Code. By default from Android O, we don't recreate the activity even the app doesn't specify mnc in configChanges. If the app wants to recreate the acvitity, specify mnc in recreateOnConfigChanges.
navigation | 40 | The navigation type has changed. Should never normally happen.
orientation | 80 | The screen orientation has changed, that is the user has rotated the device.
screenLayout | 100 | The screen layout has changed. This might be caused by a different display being activated.
screenSize | 400 | The current available screen size has changed. If applications don't target at least `Build.VERSION_CODES.HONEYCOMB_MR2` then the activity will always handle this itself (the change will not result in a restart). This represents a change in the currently available size, so will change when the user switches between landscape and portrait.
smallestScreenSize | 800 | The physical screen size has changed. If applications don't target at least `Build.VERSION_CODES.HONEYCOMB_MR2` then the activity will always handle this itself (the change will not result in a restart). This represents a change in size regardless of orientation, so will only change when the actual physical screen size has changed such as switching to an external display.
touchscreen | 8 | The touchscreen has changed. Should never normally happen.
uiMode | 200 | The global user interface mode has changed. For example, going in or out of car mode, night mode changing, etc.

### android:isDefault

Set to true in all of the configurations for which this input method should be considered an option as the default.

May be a boolean value, such as "`true`" or "`false`".

### android:settingsActivity

Component name of an activity that allows the user to modify the settings for this service.

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

### android:showInInputMethodPicker

Specifies whether the IME wants to be shown in the Input Method picker. Defaults to true. Set this to false if the IME is intended to be accessed programmatically.

Note: This functions as a hint to the system, which may choose to ignore this preference in certain situations or in future releases.

May be a boolean value, such as "`true`" or "`false`".

### android:supportsInlineSuggestions

Specifies whether the IME supports showing inline suggestions.

May be a boolean value, such as "`true`" or "`false`".

### android:supportsSwitchingToNextInputMethod

Set to true if this input method supports ways to switch to a next input method (for example, a globe key.). When this is true and InputMethodManager#shouldOfferSwitchingToNextInputMethod() returns true, the IME has to offer ways to invoke InputMethodManager#switchToNextInputMethod() 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.

May be a boolean value, such as "`true`" or "`false`".

### android:suppressesSpellChecker

Specifies whether the IME suppresses system spell checker. The default value is false. If an IME sets this attribute to true, the system spell checker will be disabled while the IME has an active input session.

May be a boolean value, such as "`true`" or "`false`".

### getSubtypeCount

    public int getSubtypeCount ()

Return the count of the subtypes of Input Method.

Returns
`int` |

### hashCode

    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(Object)` 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(java.lang.Object)` 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.

As much as is reasonably practical, the hashCode method defined by class `Object` does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the Java™ programming language.)

Returns
`int` | a hash code value for this object.

### loadIcon

    public Drawable loadIcon (PackageManager pm)

Parameters
`pm` | `PackageManager`: Supply a PackageManager used to load the input method's resources.

Returns
`Drawable` |

### loadLabel

    public CharSequence loadLabel (PackageManager pm)

Load the user-displayed label for this input method.

Parameters
`pm` | `PackageManager`: Supply a PackageManager used to load the input method's resources.

Returns
`CharSequence` |

### shouldShowInInputMethodPicker

    public boolean shouldShowInInputMethodPicker ()

Returns `true` if this input method should be shown in menus for selecting an Input Method, such as the system Input Method Picker. This is `false` if the IME is intended to be accessed programmatically.

Returns
`boolean` |

### suppressesSpellChecker

    public boolean suppressesSpellChecker ()

Return `true` if this input method suppresses spell checker.

Returns
`boolean` |

### toString

    public String toString ()

Returns a string representation of the object. In general, the `toString` method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.

The `toString` method for class `Object` returns a string consisting of the name of the class of which the object is an instance, the at-sign character ``@`', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:

>      getClass().getName() + '@' + Integer.toHexString(hashCode())

Returns
`String` | a string representation of the object.

### writeToParcel

    public void writeToParcel (Parcel dest,
                    int flags)

Used to package this object into a `Parcel`.

Parameters
`dest` | `Parcel`: The `Parcel` to be written.
`flags` | `int`: The flags used for parceling.
