inline

Sets the recycler listener to be notified whenever a View is set aside in the recycler for later reuse. This listener can be used to free resources associated to the View.

参数

listener The recycler listener to be notified of views set aside in the recycler.

参见: android.widget.AbMultiColumnBaseAbsListView.RecycleBin; android.widget.AbsListView.RecyclerListener

void com.ab.view.pullview.AbMultiColumnBaseAbsListView.setScrollingCacheEnabled ( boolean enabled)

inline

Enables or disables the children's drawing cache during a scroll. By default, the drawing cache is enabled but this will use more memory.

When the scrolling cache is enabled, the caches are kept after the first scrolling. You can manually clear the cache by calling android.view.ViewGroup#setChildrenDrawingCacheEnabled(boolean).

参数

enabled true to enable the scroll cache, false otherwise

参见: isScrollingCacheEnabled(); View::setDrawingCacheEnabled(boolean)

void com.ab.view.pullview.AbMultiColumnBaseAbsListView.setSelector ( int resID)

inline

void com.ab.view.pullview.AbMultiColumnBaseAbsListView.setSmoothScrollbarEnabled ( boolean enabled)

inline

When smooth scrollbar is enabled, the position and size of the scrollbar thumb is computed based on the number of visible pixels in the visible items. This however assumes that all list items have the same height. If you use a list in which items have different heights, the scrollbar will change appearance as the user scrolls through the list. To avoid this issue, you need to disable this property.

When smooth scrollbar is disabled, the position and size of the scrollbar thumb is based solely on the number of items in the adapter and the position of the visible items inside the adapter. This provides a stable scrollbar as the user navigates through a list of items with varying heights.

参数

enabled Whether or not to enable smooth scrollbar.

参见: setSmoothScrollbarEnabled(boolean) ref android.R.styleable::AbsListView_smoothScrollbar

void com.ab.view.pullview.AbMultiColumnBaseAbsListView.setStackFromBottom ( boolean stackFromBottom)

inline

mode	the transcript mode to set

参见: TRANSCRIPT_MODE_DISABLED; TRANSCRIPT_MODE_NORMAL; TRANSCRIPT_MODE_ALWAYS_SCROLL

boolean com.ab.view.pullview.AbMultiColumnBaseAbsListView.shouldShowSelector ( )

inlineprotected

Indicates whether this view is in a state where the selector should be drawn. This will happen if we have focus but are not in touch mode, or we are in the middle of displaying the pressed state for an item.

返回: True if the selector should be shown

boolean com.ab.view.pullview.AbMultiColumnBaseAbsListView.showContextMenuForChild ( View originalView)

position Scroll to this adapter position.

void com.ab.view.pullview.AbMultiColumnBaseAbsListView.smoothScrollToPosition	(	int	position,
		int	boundPosition
	)

inline
