I am creating a drawer layout with a relative layout and a listview inside (one for the main content and one for the navigation)
For the listview i created a custom adapter and i create each row using a list_item xml file which has an imageview and a textview.
The app runs but when i open the drawer i see only the background without the listview. Now if i try it with the ArrayAdapter (default) the listview shows up.
Any advice?
My custom adapter
public class CustomAdapter extends ArrayAdapter<Categories>{
Context context;
int layoutResourceId;
Categories[] data = null;
public CustomAdapter(Context context, int layoutResourceId, Categories[] categs) {
super(context, layoutResourceId);
this.layoutResourceId = layoutResourceId;
this.context = context;
data = categs;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View row = convertView;
PHolder holder = null;
if(row == null)
{
LayoutInflater inflater = ((Activity)context).getLayoutInflater();
row = inflater.inflate(layoutResourceId, parent, false);
holder = new PHolder();
holder.imgIcon = (ImageView)row.findViewById(R.id.categimage);
holder.txtTitle = (TextView)row.findViewById(R.id.categtext);
row.setTag(holder);
}
else
{
holder = (PHolder)row.getTag();
}
Categories categ = data[position];
holder.txtTitle.setText(categ.title);
holder.imgIcon.setImageResource(categ.icon);
return row;
}
static class PHolder
{
ImageView imgIcon;
TextView txtTitle;
}
}
And in my main activity
mDrawerList = (ListView) findViewById(R.id.categlist);
Categories data[] = new Categories[]
{
new Categories(R.drawable.restaurant, R.string.food),
new Categories(R.drawable.bar_coktail, R.string.bar),
new Categories(R.drawable.mall, R.string.shop),
new Categories(R.drawable.agritourism, R.string.out),
new Categories(R.drawable.dance_class, R.string.art),
new Categories(R.drawable.officebuilding, R.string.other),
new Categories(R.drawable.university, R.string.education),
new Categories(R.drawable.townhouse, R.string.house),
new Categories(R.drawable.junction, R.string.transport)
};
CustomAdapter ca = new CustomAdapter(this, R.layout.list_item, data);
View header = (View)getLayoutInflater().inflate(R.layout.list_header, null);
mDrawerList.addHeaderView(header);
mDrawerList.setAdapter(ca);
Either use:
super(context, layoutResourceId, categs);
in the constructor or override the getCount()
method:
@Override
public int getCount() {
return data.length;
}
