Look Inside Yourself

ActionAdapter is a class we need to implement, to pour a ResolveInfo into

the row layouts for our ListView. Hence, add the following ActionAdapter

implementation as an inner class of Contacter:

class ActionAdapter extends ArrayAdapter<ResolveInfo> {

private PackageManager pm=null;

ActionAdapter(PackageManager pm, List<ResolveInfo> apps) {

super(Contacter.this, R.layout.row, apps);

this.pm=pm;

}

@Override

public View getView(int position, View convertView,

ViewGroup parent) {

if (convertView==null) {

convertView=newView(parent);

}

bindView(position, convertView);

return(convertView);

}

private View newView(ViewGroup parent) {

return(getLayoutInflater().inflate(R.layout.row, parent, false));

}

private void bindView(int position, View row) {

TextView label=(TextView)row.findViewById(R.id.label);

label.setText(getItem(position).loadLabel(pm));

ImageView icon=(ImageView)row.findViewById(R.id.icon);

icon.setImageDrawable(getItem(position).loadIcon(pm));

}

}

At this point, you can compile and install your Contacter application.

Initially, the list is empty, so the screen just shows the button:
