添加在TabHost ExpandableListView

public class Boards : TabActivity 
{ 
    protected override void OnCreate(Bundle bundle) 
    { 
     base.OnCreate(bundle); 

     SetContentView(Resource.Layout.Tab); 

     TabHost.TabSpec spec; 
     Intent intent; 

     intent = new Intent(this, typeof(Today)); 
     intent.AddFlags(ActivityFlags.NewTask); 

     spec = TabHost.NewTabSpec("today"); 
     spec.SetIndicator("Today"); 
     spec.SetContent(intent); 
     TabHost.AddTab(spec); 

     intent = new Intent(this, typeof(Tomorrow)); 
     intent.AddFlags(ActivityFlags.NewTask); 

     spec = TabHost.NewTabSpec("tomorrow"); 
     spec.SetIndicator("Tomorrow"); 
     spec.SetContent(intent); 
     TabHost.AddTab(spec); 

     TabHost.CurrentTab = 1; 
    } 
}

Tab.axml添加在TabHost ExpandableListView

<?xml version="1.0" encoding="utf-8"?> 
<TabHost xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@android:id/tabhost" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent"> 
    <LinearLayout 
     android:layout_width="fill_parent" 
     android:layout_height="fill_parent"> 
     <TabWidget 
     android:id="@android:id/tabs" 
     android:layout_width="fill_parent" 
     android:layout_height="wrap_content"></TabWidget> 
     <FrameLayout 
     android:id="@android:id/tabcontent" 
     android:layout_width="fill_parent" 
     android:layout_height="fill_parent"></FrameLayout> 
    </LinearLayout> 
</TabHost>

Today.cs

public class Today : ExpandableListActivity 
{ 
    protected override void OnCreate(Bundle bundle) 
    { 
     base.OnCreate(bundle); 

     List<IDictionary<string, object>> parent = new List<IDictionary<string,object>>(); 
     List<IList<IDictionary<string, object>>> child = new List<IList<IDictionary<string,object>>>(); 

     External inst = new External(); 
     var connection = inst.conn(); 
     var c = connection.CreateCommand(); 
     c.CommandText = "Select Distinct Store From Calls"; 
     connection.Open(); 
     SqliteDataReader dr = c.ExecuteReader(); 
     if (dr.HasRows) 
      while (dr.Read()) 
      { 
       Dictionary<string, object> pItem = new Dictionary<string,object>(); 
       pItem.Add("Store", dr[0].ToString()); 
       parent.Add(pItem); 
      } 
     dr.Close(); 
     int cnt = parent.Count(); 

     if (cnt > 0) 
     { 
      List<IDictionary<string, object>> children = new List<IDictionary<string, object>>(); 
      foreach(IDictionary<string, object> d in parent) 
      { 
       c.CommandText = "Select CallNumber From Calls Where Store = '" + d.Values + "'"; 
       dr = c.ExecuteReader(); 
       while (dr.Read()) 
       { 
        Dictionary<string, object> childItem = new Dictionary<string, object>(); 
        childItem.Add("Call", dr[0].ToString()); 
        children.Add(childItem); 
       } 
       dr.Close(); 
      } 
      child.Add(children); 
     } 

     SimpleExpandableListAdapter adapter = new SimpleExpandableListAdapter(this, parent, Android.Resource.Layout.SimpleExpandableListItem1, new string[] { "Store" }, new int[] { Android.Resource.Id.Text1, Android.Resource.Id.Text2 }, child, Android.Resource.Layout.SimpleExpandableListItem2, new string[] { "Call" }, new int[] { Android.Resource.Id.Text1, Android.Resource.Id.Text2 }); 
     SetListAdapter(adapter); 
    } 

}

的標籤創建得很好，但如果我點擊今日選項卡帶來了ExpandableListViewActivity，什麼也不顯示上向上。我將Tab.axml中的LinearLayout更改爲Relative，然後展開ExpandableListView，但第一個項目位於today標籤的頂部，並試圖展開該項目使應用程序崩潰。

應用程序時Tab.axml具有的LinearLayout

應用程序時Tab.axml有RelativeLayout的 enter image description here

得到它的工作。解決方法是使用相對佈局保留Tab.axml，並指定FrameLayout位於TabWidget下方。

<FrameLayout 
android:id="@android:id/tabcontent" 
android:layout_width="fill_parent" 
android:layout_height="fill_parent" 
android:layout_below="@android:id/tabs"> 
</FrameLayout>
