Android自定义Gridview重复项

我正在使用gridview。我成功地创建了自定义gridview（图像和文本）。我有32项。程序运行得很好，但当我试着运行程序gridview时，最后的项目有重复。我不知道我做错了什么？ 如果有人知道答案，请帮助我

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="wrap_content"
android:layout_height="wrap_content" >

<RelativeLayout
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentLeft="true"
    android:layout_alignParentTop="true" >

    <ImageView
        android:id="@+id/grid_image"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
         >
    </ImageView>

    <TextView
        android:id="@+id/grid_text"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true"
        android:text="TextView" />
</RelativeLayout>

}

textView.setText（Flag_id[position]）；setImageResource（Imageid[位置]）超出if子句，否则它们将仅在
convertView
为空时使用。我更改了它，但在customadapter返回0中的getItemId中也有相同的问题。我认为它应该在imageview的布局\宽度布局\高度中返回位置问题，但我不知道为什么？
