列表視圖中SwipeRefreshLayout - 不顯示任何東西時，自定義適配器只有一個行顯示
在我的應用我有一個列表視圖。當我有多個項目要展示時，所有的東西都能很好地工作，但是當我在我的列表視圖中顯示一個項目時，它顯示出一種罕見的行爲。
第一：如果單個項目的高度比窗口的高度更大......它像一個魅力和正常工作（A）
二：如果單個項目的高度比窗口的高度小...有時顯示項目（B），有時不顯示項目（C）。 （C）當我嘗試刷新列表視圖時，如果我有一個項目在列表視圖中...它不顯示我的項目，如果它的高度小於窗口高度。（三）
我想不起來！任何機構都可以幫我
我知道這個問題與SwipeRefreshLayout或Listview的高度有關，當我將marginTop設置爲該視圖（作爲屏幕高度的一半）時，listview可以有效地工作。
我的XML文件是：
<android.support.v4.widget.SwipeRefreshLayout
android:id="@+id/swipe_Container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="0dp"
android:background="#FFedf1f2"
android:paddingLeft="8.5dp"
android:paddingRight="8.5dp"
android:paddingTop="0dp" >
<ListView
android:id="@+id/list"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:divider="@android:color/transparent"
android:dividerHeight="8.5dp"
android:scrollbars="none" >
</ListView>
一切工作的魅力，直到我有至少一個以上的項目列表視圖中顯示。但是當我一個項目列表視圖中顯示，我的列表視圖不顯示任何內容:(
爲什麼呢？哪裏是我的錯嗎？如果可以我是錯的？
這是我的適配器的getView()（擴展BaseAdapter - 我剪碼的某些行）：
public View getView(int position, View convertView, ViewGroup parent) {
Typeface MyriadRegular = Farsi.GetMyriadRegular(mActivity);

if(convertView == null) {

if (!mNext.equals("NONE")){
if (position >= getCount() - 1){
if(mSwipe != null){
mSwipe.setRefreshing(true);
}
loadmore();
}
}
holder.video_Duration.setTypeface(MyriadBold);
holder.video_Duration.setText(Farsi.Convert(DURATION));
holder.video_Title.setTypeface(Yagut);

JSON解析部分（我使用ION庫異步網絡）：

您是否將JSON結果放入與初始化適配器並調用'adapter.notifyDataSetChanged（）'相同的ArrayList？ – dharms 2014-10-28 21:25:32
@dcharms是的，我從getCount（）得到1 – MAY3AM 2014-10-28 21:27:33
你能顯示那部分代碼嗎？ – dharms 2014-10-28 21:31:01
