Resources.Theme

applyStyle

public void applyStyle (int resId, 
                boolean force)

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

public void dump (int priority, 
                String tag, 
                String prefix)

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

equals

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.

getAttributeResolutionStack

public int[] getAttributeResolutionStack (int defStyleAttr, 
                int defStyleRes, 
                int explicitStyleRes)

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

public int getChangingConfigurations ()

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

getDrawable

public Drawable getDrawable (int id)

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

getExplicitStyle

public int getExplicitStyle (AttributeSet set)

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

getResources

public Resources getResources ()

Returns the resources to which this theme belongs.

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 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.

obtainStyledAttributes

public TypedArray obtainStyledAttributes (AttributeSet set, 
                int[] attrs, 
                int defStyleAttr, 
                int defStyleRes)

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.

obtainStyledAttributes

public TypedArray obtainStyledAttributes (int[] attrs)

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

public TypedArray obtainStyledAttributes (int resId, 
                int[] attrs)

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.

rebase

public void rebase ()

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

resolveAttribute

public boolean resolveAttribute (int resid, 
                TypedValue outValue, 
                boolean resolveRefs)

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

setTo

public void setTo (Resources.Theme other)

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

public String toString ()

Returns a string representation of the object.
