setOnChildFocusListener

public void setOnChildFocusListener (BrowseFrameLayout.OnChildFocusListener listener)

Sets a BrowseFrameLayout.OnChildFocusListener.

Parameters
listener BrowseFrameLayout.OnChildFocusListener

setOnDispatchKeyListener

public void setOnDispatchKeyListener (View.OnKeyListener listener)

Sets the View.OnKeyListener on this view. This listener would fire only for unhandled KeyEvents.

Parameters
listener View.OnKeyListener

setOnFocusSearchListener

public void setOnFocusSearchListener (BrowseFrameLayout.OnFocusSearchListener listener)

Sets a BrowseFrameLayout.OnFocusSearchListener.

Parameters
listener BrowseFrameLayout.OnFocusSearchListener

                Rect previouslyFocusedRect)

Parameters
direction int

previouslyFocusedRect Rect
