I have a Gallery and a GridView in my application. Gallery's adapter
is based on thumbnail cursor created through query using
MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI.
I use this Gallery to choose images to display in GridView. Whenever
the user clicks on an image in the Gallery I have to add this image
to GridView. Currently, I use an ArrayAdapter<Integer> to store the
images in the GridView. The value stored as objects in the
ArrayAdapter is the _ID of the thumbnail and getView on GridView looks
like this:
public View getView(int position, View convertView, ViewGroup
parent) {
ImageView i = new ImageView(mContext);
System.out.println("I am in get view:" + position);
int thumbnailId = getItem(position);
i.setImageURI(
Uri.withAppendedPath
(MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI,
"" + thumbnailId));
i.setScaleType(ImageView.ScaleType.CENTER_CROP);
i.setLayoutParams(new GridView.LayoutParams(80, 80));
return i;
}
Whenever I click on an item in Gallery, getView is called for all
visible positions in the GridView (9 images). After, 12-13 images are
added to the gridview and I scroll up and down, I get an
OutOfMemoryError. Can someone suggest how I can rework to avoid memory
errors here.
