setFrameworkResourceIdProvider

public void setFrameworkResourceIdProvider(RenderResources.ResourceIdProvider provider)

setFrameworkResourceIdProvider

@Deprecated
public void setFrameworkResourceIdProvider(RenderResources.FrameworkResourceIdProvider provider)

Deprecated. This method will be removed after layoutlib is updated. Use setFrameworkResourceIdProvider(ResourceIdProvider)

setLogger

public void setLogger(LayoutLog logger)

getCurrentTheme

@Deprecated
public StyleResourceValue getCurrentTheme()

Deprecated. Use getDefaultTheme() or getAllThemes()

Returns the StyleResourceValue representing the current theme.

Returns:

the theme or null if there is no current theme.

getDefaultTheme

public StyleResourceValue getDefaultTheme()

applyStyle

public void applyStyle(StyleResourceValue theme,

clearStyles

public void clearStyles()

Clear all the themes applied with applyStyle(StyleResourceValue, boolean)

getAllThemes

public java.util.List<StyleResourceValue> getAllThemes()

@resType/android:resName

?resType/resName

?android:resType/resName

?resType/android:resName

Deprecated. Use resolveResValue(ResourceValue)

Kept for layoutlib. Remove ASAP.

resolveResValue

public ResourceValue resolveResValue(ResourceValue value)

Returns the ResourceValue referenced by the value of value.
