I'm trying to put an image view in adapter.
I'm trying to do this because I saw an example of putting TextView in ArrayAdapter, like this :
adapter = new ArrayAdapter<String>(this.getActivity(), android.R.layout.simple_list_item_1, transmit_noktp_list) {
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View view = super.getView(position, convertView, parent);
TextView text = (TextView) view.findViewById(android.R.id.text1);
return view;
}
};
So derived from the example, then I tried to put ImageView also to achieve icon & text on each list item :
So tried :
adapter = new ArrayAdapter<String>(this.getActivity(), android.R.layout.simple_list_item_1, transmit_noktp_list) {
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View view = super.getView(position, convertView, parent);
ImageView img = (ImageView) view.findViewById(android.R.id.icon1);
TextView text = (TextView) view.findViewById(android.R.id.text1);
Resources resources = getResources();
img.setImageDrawable(resources.getDrawable(R.drawable.inbox));
return view;
}
};
suprisingly this img.setImageDrawable(resources.getDrawable(R.drawable.inbox)); line throwed me an exception (I can assured that 'inbox' icon is in res/drawable, it's even showed in my IDE) :
