Question

我想使用LayouInflater以编程方式创建我的relativeLayout但是它在AddView方法上抛出错误，继承人是我的代码：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"  
  android:id="@+id/relativeAgedSummary"     
  android:layout_width="match_parent"
  android:layout_height="match_parent" >
</RelativeLayout>

ViewGroup relativeAgedSummary=FindViewById<ViewGroup>(Resource.Id.relativeAgedSummary);
View view = this.LayoutInflater.Inflate(
                                Resource.Layout.aged_summary_list_item, 
                                relativeAgedSummary, false);    

for (int i = 0; i < agedValues.Count; i++) {
    var row = agedValues.ElementAt(i);
    if(row.Range  == 0 && row.IsTotal == false)
    {
        RelativeLayout rl = view.FindViewById<RelativeLayout>(
                                           Resource.Id.relativeLayoutAgedSummaryItem);
        rl.SetBackgroundResource(Resource.Color.lightBlue); 
        if(contA==0)
        {
           TextView tv = (TextView)view.FindViewById(Resource.Id.txtAgedSummary); 
           tv.SetText(labelsAgedSummary[row.Range], TextView.BufferType.Normal);
           contA++;
        }           
        relativeAgedSummary.AddView(view);
    }

你是什么意思“它只出现一个”。如果您尝试向relativeAgedSummary添加多个实例，则每次都需要重新充气aged_summary_list_item：

for (int i = 0; i < agedValues.Count; i++)
{
    View view = this.LayoutInflater.Inflate(
                    Resource.Layout.aged_summary_list_item, 
                    relativeAgedSummary, false);

    var row = agedValues.ElementAt(i);

    // the logic here...

    relativeAgedSummary.AddView(view);
}

这是因为您尝试多次添加同一个对象。它将忽略添加。然后在循环中重复修改相同的项目，从而导致它看起来像只添加了“最后”项目。
