Scroll Issue in Multilevel ExpandableListview in android
I have browsed for implementing multilevel ExpandableListView and i came to know with very important
Stackoverflow Link: Link1
Implemented multilevel ExpandableListview with Blog but faced problem that all child not visible and can't scroll at 3rd level. So i searched for scrolling issues and found here that which blog i am following gave static height and width of ExpandableListview in onMessured.
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec)
{
widthMeasureSpec = MeasureSpec.makeMeasureSpec(960, MeasureSpec.AT_MOST);
heightMeasureSpec = MeasureSpec.makeMeasureSpec(600, MeasureSpec.AT_MOST);
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
}
replaced with
@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec){
widthMeasureSpec = MeasureSpec.makeMeasureSpec(MeasureSpec.getSize(widthMeasureSpec), MeasureSpec.EXACTLY);
heightMeasureSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE, MeasureSpec.AT_MOST);
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
}
So my scrolling issue gone but because of maximum height .
heightMeasureSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE, MeasureSpec.AT_MOST);
given to elv getChildView of 2nd Elv called only once and all child loading at first time. This will causing memory issue for large set of data and i can't applied pull to refresh.
how to resolve this issue and any batter idea to implement multilevel ELV?
