public final class Configuration
extends Object implements Parcelable, Comparable<Configuration>

java.lang.Object
↳	android.content.res.Configuration

This class describes all device configuration information that can impact the resources the application retrieves. This includes both user-specified configuration options (locale list and scaling) as well as device configurations (such as input modes, screen size and screen orientation).

You can acquire this object from Resources, using Resources.getConfiguration(). Thus, from an activity, you can get it by chaining the request with ContextThemeWrapper.getResources():

Configuration config = getResources().getConfiguration();

Public constructors

Configuration

public Configuration ()

Construct an invalid Configuration. This state is only suitable for constructing a Configuration delta that will be applied to some valid Configuration object. In order to create a valid standalone Configuration, you must call setToDefaults().

Example:

     Configuration validConfig = new Configuration();
     validConfig.setToDefaults();

     Configuration deltaOnlyConfig = new Configuration();
     deltaOnlyConfig.orientation = Configuration.ORIENTATION_LANDSCAPE;

     validConfig.updateFrom(deltaOnlyConfig);

equals

public boolean equals (Configuration that)

Parameters
`that`	`Configuration`

Returns
`boolean`

equals

public boolean equals (Object that)

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.

The equals method for class Object implements the most discriminating possible equivalence relation on objects; that is, for any non-null reference values x and y, this method returns true if and only if x and y refer to the same object (x == y has the value true).

Note that it is generally necessary to override the hashCode method whenever this method is overridden, so as to maintain the general contract for the hashCode method, which states that equal objects must have equal hash codes.

Parameters
`that`	`Object`: This value may be `null`.

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

getLayoutDirection

public int getLayoutDirection ()

Return the layout direction. Will be either View#LAYOUT_DIRECTION_LTR or View#LAYOUT_DIRECTION_RTL.

Returns
`int`	Returns `View#LAYOUT_DIRECTION_RTL` if the configuration is `SCREENLAYOUT_LAYOUTDIR_RTL`, otherwise `View#LAYOUT_DIRECTION_LTR`.

getLocales

public LocaleList getLocales ()

Get the locale list. This is the preferred way for getting the locales (instead of using the direct accessor to locale, which would only provide the primary locale).

Returns
`LocaleList`	The locale list. This value cannot be `null`.

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.

isLayoutSizeAtLeast

public boolean isLayoutSizeAtLeast (int size)

Check if the Configuration's current screenLayout is at least the given size.

Parameters
`size`	`int`: The desired size, either `SCREENLAYOUT_SIZE_SMALL`, `SCREENLAYOUT_SIZE_NORMAL`, `SCREENLAYOUT_SIZE_LARGE`, or `SCREENLAYOUT_SIZE_XLARGE`.

Returns
`boolean`	Returns true if the current screen layout size is at least the given size.

isNightModeActive

public boolean isNightModeActive ()

Retuns whether the configuration is in night mode

Returns
`boolean`	true if night mode is active and false otherwise

isScreenHdr

public boolean isScreenHdr ()

Return whether the screen has a high dynamic range.

Returns
`boolean`	true if the screen has a high dynamic range, false otherwise

isScreenRound

public boolean isScreenRound ()

Return whether the screen has a round shape. Apps may choose to change styling based on this property, such as the alignment or layout of text or informational icons.

Returns
`boolean`	true if the screen is rounded, false otherwise

isScreenWideColorGamut

public boolean isScreenWideColorGamut ()

Return whether the screen has a wide color gamut and wide color gamut rendering is supported by this device. When true, it implies the screen is colorspace aware but not necessarily color-managed. The final colors may still be changed by the screen depending on user settings.

Returns
`boolean`	true if the screen has a wide color gamut and wide color gamut rendering is supported, false otherwise

needNewResources

public static boolean needNewResources (int configChanges, 
                int interestingChanges)

readFromParcel

public void readFromParcel (Parcel source)

Parameters
`source`	`Parcel`

setLayoutDirection

public void setLayoutDirection (Locale loc)

Set the layout direction from a Locale.

Parameters
`loc`	`Locale`: The Locale. If null will set the layout direction to `View#LAYOUT_DIRECTION_LTR`. If not null will set it to the layout direction corresponding to the Locale.

See also:

setLocale

public void setLocale (Locale loc)

Set the locale list to a list of just one locale. This will also set the layout direction according to the locale. Note that after this is run, calling .equals() on the input locale and the locale attribute would return true if they are not null, but there is no guarantee that they would be the same object. See also the note about layout direction in setLocales(android.os.LocaleList).

Parameters
`loc`	`Locale`: The locale. Can be null. This value may be `null`.

setLocales

public void setLocales (LocaleList locales)

Set the locale list. This is the preferred way for setting up the locales (instead of using the direct accessor or setLocale(java.util.Locale)). This will also set the layout direction according to the first locale in the list. Note that the layout direction will always come from the first locale in the locale list, even if the locale is not supported by the resources (the resources may only support another locale further down the list which has a different direction).

Parameters
`locales`	`LocaleList`: The locale list. If null, an empty LocaleList will be assigned. This value may be `null`.

setTo

public void setTo (Configuration o)

Sets the fields in this object to those in the given Configuration.

Parameters
`o`	`Configuration`: The Configuration object used to set the values of this Configuration's fields.

setToDefaults

public void setToDefaults ()

Set this object to the system defaults.

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.

updateFrom

public int updateFrom (Configuration delta)

Copies the fields from delta into this Configuration object, keeping track of which ones have changed. Any undefined fields in delta are ignored and not copied in to the current Configuration.

Parameters
`delta`	`Configuration`: This value cannot be `null`.

Returns

Returns
`int`	a bit mask of the changed fields, as per `diff(Configuration)` Value is either `0` or a combination of `ActivityInfo.CONFIG_MCC`, `ActivityInfo.CONFIG_MNC`, `ActivityInfo.CONFIG_LOCALE`, `ActivityInfo.CONFIG_TOUCHSCREEN`, `ActivityInfo.CONFIG_KEYBOARD`, `ActivityInfo.CONFIG_KEYBOARD_HIDDEN`, `ActivityInfo.CONFIG_NAVIGATION`, `ActivityInfo.CONFIG_ORIENTATION`, `ActivityInfo.CONFIG_SCREEN_LAYOUT`, `ActivityInfo.CONFIG_UI_MODE`, `ActivityInfo.CONFIG_SCREEN_SIZE`, `ActivityInfo.CONFIG_SMALLEST_SCREEN_SIZE`, `ActivityInfo.CONFIG_DENSITY`, `ActivityInfo.CONFIG_LAYOUT_DIRECTION`, `ActivityInfo.CONFIG_COLOR_MODE`, and `ActivityInfo.CONFIG_FONT_SCALE`
