android Listview下滑，自動載入資料.修改多處地方，去除重繪listvew,防止閃爍

標籤：android   style   blog   io   ar   使用   sp   java   for   

感謝其他大神的的源碼支援
我僅在此源碼上進行修改以及注釋。
使用方法：
//設定載入分頁資料監聽
loadingListView.setOnLoadMoreListener(new OnLoadMoreListener() {
public void onLoadMore() {
if(page<3){
}else{
loadingListView.onLoadMoreComplete();//移除載入更多布局，載入完成
loadingListView.setIsEnable(false); //ture:允許開啟下滑，自動載入資料，false不允許下滑載入資料
}
}

});

整個代碼比較簡單只有一個類
