Public Constructors

public MutableContextWrapper (Context base)

Public Methods

public void setBaseContext (Context base)

Change the base context for this ContextWrapper. All calls will then be delegated to the base context. Unlike ContextWrapper, the base context can be changed even after one is already set.

Parameters

base	The new base context for this wrapper.
