Hi,
I have listview and i will be loading a RelativeLayout as its row
contents
<ListView android:id="@android:id/list"
android:layout_width="fill_parent"
android:layout_height="wrap_content"/>
rowcontents.xml
--------------------
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<ImageView
android:layout_width="60px"
android:layout_height="60px"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
</RelativeLayout >
When scrolling the list i need to re assign the image source. Am
trying to get whole contents of the row to a local variable and using
getChild(index) .
Inside scroll listener
----------------------------
for(int i=view.getFirstVisiblePosition();
i<view.getLastVisiblePosition; i++)
{
RelativeLayout rl = (RelativeLayout) getListView().getChildAt(i);
imageView iv = (ImageView) rl.getChildAt(0);
iv.setImageResource(R.drawable.eatin);
}
but, am getting NullPointerException. Please give suggestions.
Regards
Veradis
