自己建一个listview
public class MyListView extends ListView {
public MyListView(Context context) {
super(context);
}
public MyListView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public MyListView(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
}
/**
* 重新计算高度
* @param widthMeasureSpec
* @param heightMeasureSpec
*/
@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2, MeasureSpec.AT_MOST);
super.onMeasure(widthMeasureSpec, expandSpec);
}
/* @Override
protected void onLayout(boolean changed, int l, int t, int r, int b) {
super.onLayout(changed, l, t, r, b);
}
@Override
protected void onDraw(Canvas canvas) {
super.onDraw(canvas);
}*/
}

和Grid,listfresh用法一样
public class FragmentScrollView extends Fragment {
private PullToRefreshScrollView refreshScrollView;
private ViewPager viewPager;
private ListView listView;
private List
private int page_num = 1;
private ListViewAdapter listViewAdapter;
private ILoadingLayout startLabels;
private List

@Override
public void handleMessage(Message msg) {
if (msg.what == 0){
//显示下一页....拿到当前页+1
viewPager.setCurrentItem(viewPager.getCurrentItem() +1);
//再次发送消息
handler.sendEmptyMessageDelayed(0,2000);
}
}
};
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_scroll_layout, container, false);
refreshScrollView = view.findViewById(R.id.refresh_scroll_view);
viewPager = view.findViewById(R.id.image_view_pager);
listView = view.findViewById(R.id.scroll_list_view);
return view;
}
@Override
public void onActivityCreated(@Nullable Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
//失去焦点
listView.setFocusable(false);
//轮播图

//listView展示数据
