示例1: initList
import android.widget.AbsListView; //导入方法依赖的package包/类
/**
* According the view mode, get the common object for the adapter.
*/
private void initList(final AbsListView list){
list.setOnItemClickListener(this);
list.setOnItemLongClickListener(this);
// register for context menu.
list.setOnCreateContextMenuListener(this);
list.setOnScrollListener(this);
list.setOnTouchListener(this);
list.setChoiceMode(AbsListView.CHOICE_MODE_NONE);
// Setup key listener to open extender with right key or L1 or R1 or "i"
list.setOnKeyListener(new OnKeyListener() {
public boolean onKey(View v, int keyCode, KeyEvent event) {
// All is done on action down because it also moves the focus, hence we can't wait for action up
/*
* Work around to handle issues on focus for android 4.1
*
* Sometimes it is impossible to down with the pad.
* what we know :
* before going to the onkey method, list should have scrolled (except when and issue occured)
* so, if we are going down, the last visible item has to be focused item +1 (focus is done after the function, when return false)
* if last visible item == selected item even if this isn't the last item of the list, then the list won't scroll anymore.
* So we scroll it manually.
