I've had so many emails about how to get SectionIndexer to pick up a
change in the dataset that I'm publishing my tweak here. It works the
same whether you're using a GridView or ListView.
private void jiggleGrid() {
int newWidth = flag( FLAG_THUMB_PLUS ) ?
FrameLayout.LayoutParams.FILL_PARENT :
grid.getWidth() - 1;
FrameLayout.LayoutParams l = new
FrameLayout.LayoutParams(
newWidth,
FrameLayout.LayoutParams.FILL_PARENT
);
grid.setLayoutParams( l );
toggleFlag( FLAG_THUMB_PLUS );
}
flag() and toggleFlag() are my own functions.
