TabSwitcher.java 文件源码

/**
 * Obtains all attributes from a specific attribute set.
 *
 * @param attributeSet
 *         The attribute set, the attributes should be obtained from, as an instance of the type
 *         {@link AttributeSet} or null, if no attributes should be obtained
 * @param defaultStyle
 *         The default style to apply to this view. If 0, no style will be applied (beyond what
 *         is included in the theme). This may either be an attribute resource, whose value will
 *         be retrieved from the current theme, or an explicit style resource
 * @param defaultStyleResource
 *         A resource identifier of a style resource that supplies default values for the view,
 *         used only if the default style is 0 or can not be found in the theme. Can be 0 to not
 *         look for defaults
