Configuration

extends Object
implements Parcelable Comparable<T>
java.lang.Object
   ↳ android.content.res.Configuration

Class Overview

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

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

Configuration config = getResources().getConfiguration();

Public Constructors

public Configuration ()

Added in API level 1

Construct an invalid Configuration. You must call setToDefaults() for this object to be valid.

public Configuration (Configuration o)

Added in API level 1

Makes a deep copy suitable for modification.

Public Methods

public int compareTo (Configuration that)

Added in API level 1

public int describeContents ()

Added in API level 1

Parcelable methods

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

public boolean equals (Configuration that)

Added in API level 1

public boolean equals (Object that)

Added in API level 1

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

public int getLayoutDirection ()

Added in API level 17

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

Returns

public int hashCode ()

Added in API level 1

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 isLayoutSizeAtLeast (int size)

Added in API level 11

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

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

public static boolean needNewResources (int configChanges, int interestingChanges)

Added in API level 1

Determine if a new resource needs to be loaded from the bit set of configuration changes returned by updateFrom(Configuration).

Parameters
configChanges The mask of changes configurations as returned by updateFrom(Configuration).
interestingChanges The configuration changes that the resource can handled, as given in changingConfigurations.
Returns
  • Return true if the resource needs to be loaded, else false.

public void readFromParcel (Parcel source)

Added in API level 8

public void setLayoutDirection (Locale locale)

Added in API level 17

Set the layout direction from the Locale.

Parameters
locale The Locale. If null will set the layout direction to LAYOUT_DIRECTION_LTR. If not null will set it to the layout direction corresponding to the Locale.

public void setLocale (Locale loc)

Added in API level 17

Set the locale. This is the preferred way for setting up the locale (instead of using the direct accessor). This will also set the userLocale and layout direction according to the locale.

Parameters
loc The locale. Can be null.

public void setTo (Configuration o)

Added in API level 8

public void setToDefaults ()

Added in API level 1

Set this object to the system defaults.

public String toString ()

Added in API level 1

Returns a string containing a concise, human-readable description of this object. Subclasses are encouraged to override this method and provide an implementation that takes into account the object's type and data. The default implementation is equivalent to the following expression:

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

See Writing a useful toString method if you intend implementing your own toString method.

Returns
  • a printable representation of this object.

public int updateFrom (Configuration delta)

Added in API level 1
