Hi all,
I have a gridView where I want to eb able to "toggle" the item icons.
I.e when I click one of the items I want the cino to switch appearance
from, say bitmap A, to bitmap B. When I click it again it should
switch back to bitmap A.
I've got the logic in place but I cannot get the gridView to redraw
after I have handled the item click. I have tried with requestLayout()
but the only thing tht happens after clicking is that my adapter's
getView() gets called twice with position==0 regardless of which item
I clicked. The icon doesn't change.
What am I missing?
At startup the icons are nicely drawn so the getView() returns correct
imageViews.
Here are some code snippets:
>>
...
final GridView myGrid = (GridView) getViewById(...);
assetGrid.setOnItemClickListener(new AdapterView.OnItemClickListener
()
{
@Override
public void onItemClick(AdapterView<?> parent,
View view,
int position,
long id)
{
// Toggle icon
toggleItemIcon(position);
myGrid.requestLayout();
}
});
>> The getView() of my adapter. getItemIcon() returns a bitmap depending on
>> what state the item is in.
@Override
public View getView(int position, View convertView, ViewGroup
parent)
{
ImageView imageView;
if (convertView == null)
{
// Create the image view if we aren't recycling an old
view.
imageView = new ImageView(context);
imageView.setScaleType(ImageView.ScaleType.FIT_XY);
}
else
{
imageView = (ImageView) (convertView);
}
imageView.setImageBitmap(getItemIcon(position));
return imageView;
}
Any ideas are much appreciated.
Thanks,
Rickard
