Custom ListView error when inserting many Views

Actually I have created a custom ListView. I want to add items to this custom ListView dynamically. But in my case, the first item is inserted without any problem but when I try to insert the second item it gives an error. If anyone knows how to solve this, please suggest it to me.

main.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
android:id="@+id/relativeLayout1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android">

<ListView
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:id="@+id/historyFrmLstView2"
android:layout_alignParentLeft="true"
android:layout_below="@+id/historyFrmLstView1"
android:layout_marginTop="20dip"
android:layout_marginBottom="10dip">
</ListView> 

 </RelativeLayout>

Hi i think that may be used below code..

public void displayHistory()
 {
    String strDisplay[] = {" "};
    historyFrmLstView2 = (ListView) findViewById(R.id.historyFrmLstView2);
    int iHistCount = CycleManager.getSingletonObject().getHistoryCount();
    int i;
    SimpleDateFormat sdFormatter = new SimpleDateFormat("dd-MMMM-yyyy");

    for (i=0; i<iHistCount; i++)
    {
            strDisplay[i] = "";

            Date dtHist = CycleManager.getSingletonObject().getHistoryDate(iHistCount);

            strDisplay[i]=sdFormatter.format(dtHist.getTime());


    }

     aHistFrmAdpter2 = new HistoryFrmCustomAdapter2(this,strDisplay);
     historyFrmLstView2.setAdapter(aHistFrmAdpter2);  
 }

there will be only one element in your string array strDisplay[iHistCount]. since you r putting value at the last position each time. replace iHistCount with i.
