Why my items are not redrawn after invoking `invalidateViews()` ?
I ask because i try to refresh `listItems` after a bg-thread notify an image rsc was downloaded.
But nothing is updated. Only after exiting and re-entering the new icons are drawn.
I have an activity with `adapter` of type `SettingValueAdapter extends BaseAdapter`
it has a member:
`private SettingsValue[] values;`
it has two interesting methods:
@Override
public View getView(int position, View view, ViewGroup parent) {
AddressItem ai= (AddressItem)getItem(position);
DriveToNativeManager dnm = DriveToNativeManager.getInstance();
if (view == null) {
LayoutInflater li = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
view = li.inflate(R.layout.address_item, null);
}
view.setTag(R.id.addressItem,ai);
view.setTag(position);
view.findViewById(R.id.fullAddressItemCol).setVisibility(View.VISIBLE);
view.findViewById(R.id.addressItemTouch).setVisibility(View.GONE);
view.findViewById(R.id.addressItemImage).setVisibility(View.GONE);
if (ai != null) {
...
}
view.findViewById(R.id.addressItemIconLayout).setVisibility(View.VISIBLE);
Drawable icon = ResManager.GetSkinDrawable(ai.getIcon() + ".bin");
((ImageView)view.findViewById(R.id.addressItemIcon)).setImageDrawable(icon);
..
}
I attach a callback to the bg-thread (c language) image downloading process.
The callback switches to the ui-thread and calls this `refreshList`:
public void refreshSearchIconsOnSearchActivity() {
Runnable refreshViewEvent = new Runnable() {
@Override
public void run() {
Activity currentActivity = AppService.getActiveActivity();
if (currentActivity instanceof SearchActivity) {
Log.d("w", "refreshSearchIconsOnSearchActivity callback running in thread "
+ Thread.currentThread().getId() );
//results list
((SearchActivity) currentActivity).refreshList();
}
}
};
AppService.Post(refreshViewEvent);
}
However, the images are done downloading and are not refreshed on the activity.
They are refreshed only when I leave an re-enter the activity.
What am I missing?
