Note: System services obtained via this API may be closely associated with the Context in which they are obtained from. In general, do not share the service objects between various different contexts (Activities, Applications, Services, Providers, etc.)

Parameters

name The name of the desired service.

public Resources.Theme getTheme()

Return the Theme object associated with this Context.

public void setTheme(int resid)

Set the base theme for this context. Note that this should be called before any views are instantiated in the Context (for example before calling setContentView(View) or inflate(int, ViewGroup)).

Parameters

resid The style resource describing the theme.

Protected Methods

protected void attachBaseContext(Context newBase)

Set the base context for this ContextWrapper. All calls will then be delegated to the base context. Throws IllegalStateException if a base context has already been set.

Parameters

newBase The new base context for this wrapper.

protected void onApplyThemeResource(Resources.Theme theme, int resid, boolean first)

Called by setTheme(int) and getTheme() to apply a theme resource to the current Theme object. Can override to change the default (simple) behavior. This method will not be called in multiple threads simultaneously.

Parameters

theme The Theme object being modified.
resid The theme style resource being applied to theme.
first Set to true if this is the first time a style is being applied to theme.
