Method Detail

processViews

public static void processViews(@Nonnull
                                android.view.View view,

Method runs through view and all it's children recursively and process them via viewProcessor

Parameters:

view - parent view to be processed, if view is ViewGroup then all it's children will be processed

viewProcessor - object which processes views

processViewsOfType

public static <T> void processViewsOfType(@Nonnull
                                          android.view.View view,
                                          @Nonnull
                                          Class<T> viewClass,

                                          Views.ViewProcessor<T> viewProcessor)

Method runs through view and all it's children recursively and process all instances of viewClass via viewProcessor

Parameters:

view - parent view to be processed, if view is ViewGroup then all it's children will be processed

viewClass - only instances of specified class will be processed

viewProcessor - object which processes views

centerAndWrapTabsFor

public static void centerAndWrapTabsFor(@Nonnull
                                        android.widget.TabHost tabHost)
