Adding Custom Font in a Listview

Question

Please pardon my ignorance, I'm a total newbie to programming. I'm trying to add a custom font to this android app with a listview. I copied this code from an answer to a similar question asked here: Custom font for Android listview

 class CustomAdapter extends ArrayAdapter<CharSequence>{

    Context context; 
    int layoutResourceId;    
    CharSequence data[] = null;
    Typeface tf; 

public CustomAdapter(Context context, int layoutResourceId, CharSequence[] data, String FONT ) { 
    super(context, layoutResourceId, data);
    this.layoutResourceId = layoutResourceId;
    this.context = context;
    this.data = data;
    tf = Typeface.createFromAsset(context.getAssets(), FONT);
} 

But I'm struggling figuring out where to put this line of code:

 listAdapter = new CustomAdapter(this, R.layout.custom_list_text, R.array.abra_hotel,   
 "name_of_font.ttf");

No matter where I try placing it, it throws an error...

Here is my MainActivity class:

 public class MainActivity extends Activity {



// XML node keys
static final String KEY_TAG = "weatherdata"; // parent node
static final String KEY_ID = "id";
static final String KEY_CITY = "city";
static final String KEY_TEMP_C = "tempc";
static final String KEY_TEMP_F = "tempf";
static final String KEY_CONDN = "condition";
static final String KEY_SPEED = "windspeed";
static final String KEY_ICON = "icon";

// List items 
ListView list;
BinderData adapter = null;
List<HashMap<String,String>> weatherDataCollection;




@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

        // normalize text representation
        doc.getDocumentElement ().normalize ();

        NodeList weatherList = doc.getElementsByTagName("weatherdata");

        HashMap<String,String> map = null;

Answer 1

use this class to customize your list...

  class CustomListAdapter extends BaseAdapter{

    LayoutInflater inflater=null;

    int count=0;
    String[] List;
    Context context;
    public CustomListAdapter(Context c,String[] list){

        List = list;
        count =  list.length;
        context=c;

        inflater = (LayoutInflater)c.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

    }
    @Override
    public int getCount() {
        // TODO Auto-generated method stub
        return count;
    }

    @Override
    public Object getItem(int position) {
        // TODO Auto-generated method stub
        return position;
    }

    @Override
    public long getItemId(int postion) {
        // TODO Auto-generated method stub
        return postion;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        // TODO Auto-generated method stub
        View view = convertView;
        view = inflater.inflate(R.layout.row, null);
        TextView TextofList = (TextView) view.findViewById(R.id.tv_list);
        float textsize = 15.0;
                    TextofList.setTextSize(textsize);
                    TextofList.setText(List[position]);
        return view;
    }

}

and also add below given lines to your activity class....

 public class MainActivity extends Activity {
 @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
          String[] list = {"abc","cde,","add",,"cde,","add",,"cde,","add"};
     ListView listv= (ListView) findViewById(R.id.listview);

 CustomListAdapter adapter = new CustomListAdapter(this,list);
 listv.setAdapter(adapter);  
 }//end of OnCreat()
 }//end of mainactivty

hope this will help you

You need to create a custom ArrayAdapter. Check this tutoria first then change the font of the items in the adapter.
