Listview崩溃像expandablelistview一样工作

Question

我在我的项目中使用以下listview和listitems。如果我加载项目，则第一个相对布局仅可见，第二个relativelayout（三个按钮）对于所有列表项是不可见的，当我单击一个列表项时，它显示第二个相对布局项（三个按钮），然后单击第二个列表项已打开的第一个列表项（三个按钮）不可见。现在可单击的列表项可见三个按钮。它像一个可扩展的列表视图折叠项目 请任何人帮助我...

在我的列表视图中：

<ListView
    android:id="@+id/frontpagetasklistid"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content" >
</ListView>

Listview项目：

     <?xml version="1.0" encoding="utf-8"?>
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical" >

        <RelativeLayout
            android:layout_width="fill_parent"
            android:layout_height="wrap_content" >
        <TextView
            android:id="@+id/tasknameidDaytoDay"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content" />

            <ImageButton
                android:layout_alignParentRight="true"

                android:onClick="editButtonClick" >
            </ImageButton>
        </RelativeLayout>
        <RelativeLayout 
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"

        <Button

            android:textSize="15dip"
            android:layout_weight="1"/>

        <Button

在我的主要活动OnItemclick：

        Button
        buttonSeverity=(Button)arg1.findViewById(R.id.severityidDaytoDay);
        Button buttonAlarm=(Button)arg1.findViewById(R.id.alarmidDaytoDay);

        buttonAlarm.setVisibility(arg1.VISIBLE);
        buttonSeverity.setVisibility(arg1.VISIBLE);
        buttonTaskTime.setVisibility(arg1.VISIBLE); 
}
