how to add typeface and select a font from assets folder to customise list activity titles

Question

public class MainActivity extends ListActivity {
/**
 * This class describes an individual sample (the sample title, and the activity class that
 * demonstrates this sample).
 */
  private class Sample {
    private CharSequence title;
    private Class<? extends Activity> activityClass;

    public Sample(int titleResId, Class<? extends Activity> activityClass) {
        this.activityClass = activityClass;
        this.title = getResources().getString(titleResId);
    }

    @Override
    public String toString() {
        return title.toString();
    }
  }

/**
 * The collection of all samples in the app. This gets instantiated in {@link
 * #onCreate(android.os.Bundle)} because the {@link Sample} constructor needs access to {@link
 * android.content.res.Resources}.
 */

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

    // Instantiate the list of samples.

Answer 1

The inconvenience with custom fonts is that it should be manually set it to every TextView. Please have a look at example below of one approach in your case. Of course font asset should be loaded once in static field to perform better.

setListAdapter(new ArrayAdapter<Sample>(this,
            android.R.layout.simple_list_item_1,
            android.R.id.text1,
            mSamples) {
        @Override
        public View getView(int position, View convertView, ViewGroup parent)
        {
            View view = super.getView(position, convertView, parent);
            TextView textView = (TextView) view.findViewById(R.id.text1);
            textView.setTypeface(Typeface.createFromAsset(getAssets(), "myfont.ttf"));
            return view;
        }
    });
