Theme

applyStyle

fun applyStyle(
    resId: Int, 
    force: Boolean
): Unit

Place new attribute values into the theme. The style resource specified by resid will be retrieved from this Theme's resources, its values placed into the Theme object.

The semantics of this function depends on the force argument: If false, only values that are not already defined in the theme will be copied from the system resource; otherwise, if any of the style's attributes are already defined in the theme, the current values in the theme will be overwritten.

dump

fun dump(
    priority: Int, 
    tag: String!, 
    prefix: String!
): Unit

Print contents of this theme out to the log. For debugging only.

equals

fun equals(other: Any?): Boolean

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.

getAttributeResolutionStack

fun getAttributeResolutionStack(
    defStyleAttr: Int, 
    defStyleRes: Int, 
    explicitStyleRes: Int
): IntArray

Returns the ordered list of resource ID that are considered when resolving attribute values when making an equivalent call to obtainStyledAttributes(android.util.AttributeSet,int[],int,int) . The list will include a set of explicit styles (explicitStyleRes and it will include the default styles (defStyleAttr and defStyleRes).

getChangingConfigurations

fun getChangingConfigurations(): Int

Returns a bit mask of configuration changes that will impact this theme (and thus require completely reloading it).

getDrawable

fun getDrawable(id: Int): Drawable!

Return a drawable object associated with a particular resource ID and styled for the Theme.

getExplicitStyle

fun getExplicitStyle(set: AttributeSet?): Int

Returns the resource ID for the style specified using style="..." in the AttributeSet's backing XML element or Resources#ID_NULL otherwise if not specified or otherwise not applicable.

Each android.view.View can have an explicit style specified in the layout file. This style is used first during the android.view.View attribute resolution, then if an attribute is not defined there the resource system looks at default style and theme as fallbacks.

getResources

fun getResources(): Resources!

Returns the resources to which this theme belongs.

hashCode

fun hashCode(): Int

obtainStyledAttributes

fun obtainStyledAttributes(attrs: IntArray): TypedArray

Return a TypedArray holding the values defined by Theme which are listed in attrs.

Be sure to call TypedArray.recycle() when you are done with the array.

obtainStyledAttributes

fun obtainStyledAttributes(
    resId: Int, 
    attrs: IntArray
): TypedArray

Return a TypedArray holding the values defined by the style resource resid which are listed in attrs.

Be sure to call TypedArray.recycle() when you are done with the array.

obtainStyledAttributes

fun obtainStyledAttributes(
    set: AttributeSet?, 
    attrs: IntArray, 
    defStyleAttr: Int, 
    defStyleRes: Int
): TypedArray

Return a TypedArray holding the attribute values in set that are listed in attrs. In addition, if the given AttributeSet specifies a style class (through the "style" attribute), that style will be applied on top of the base attributes it defines.

Be sure to call TypedArray.recycle() when you are done with the array.

When determining the final value of a particular attribute, there are four inputs that come into play:

1. Any attribute values in the given AttributeSet.
2. The style resource specified in the AttributeSet (named "style").
3. The default style specified by defStyleAttr and defStyleRes
4. The base values in this theme.

Each of these inputs is considered in-order, with the first listed taking precedence over the following ones. In other words, if in the AttributeSet you have supplied <Button textColor="#ff000000">, then the button's text will always be black, regardless of what is specified in any of the styles.

rebase

fun rebase(): Unit

Rebases the theme against the parent Resource object's current configuration by re-applying the styles passed to applyStyle(int,boolean).

resolveAttribute

fun resolveAttribute(
    resid: Int, 
    outValue: TypedValue!, 
    resolveRefs: Boolean
): Boolean

Retrieve the value of an attribute in the Theme. The contents of outValue are ultimately filled in by android.content.res.Resources#getValue.

setTo

fun setTo(other: Resources.Theme!): Unit

Set this theme to hold the same contents as the theme other. If both of these themes are from the same Resources object, they will be identical after this function returns. If they are from different Resources, only the resources they have in common will be set in this theme.

toString

fun toString(): String
