TypefaceHelper

Helper object for injecting typeface into various text views of android.

Overview

We can use various custom typefaces asset for any text views(like TextView, Button, RadioButton, EditText, etc.), but there's no way to set the typeface as a styled theme to apply the typeface for overall screens in the app.

This library helps to do it in easy way :)

And there's also a serious bug that creating typeface from asset resource will cause memory leak (See this link for more details), this library will take care about this problem as well.

How to use

First, put your typeface into asset directory.

In your application class, take care about the helper object lifecycle.

public class MyApp extends Application {
  @Override
  public void onCreate() {
    super.onCreate();

    TypefaceHelper.initialize(this);
  }

  @Override
  public void onTerminate() {
    TypefaceHelper.destroy();
    super.onTerminate();
  }
}

And in your activity, if you would like to set your typeface to a text view,

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

    TextView hello = (TextView) findViewById(R.id.hello_world);
    TypefaceHelper.getInstance().setTypeface(hello, "font/font_file.ttf");
  }
}

You can also set your typeface for all text views that belong to a specific view group just like this.

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

    LinearLayout container = (LinearLayout) findViewById(R.id.text_container);
    TypefaceHelper.getInstance().setTypeface(container, "font/font_file.ttf");
  }
}

If you want to apply the typeface for all text views under the activity layout,

public class MyActivity extends Activity {
  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(TypefaceHelper.getInstance().setTypeface(this, R.layout.activity_main, "font/font_file.ttf"));
  }
}

Nice and easy!

You can apply the typeface to your whole window like this.

public class MyActivity extends Activity {
  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.layout_activity_main);
    TypefaceHelper.getInstance().setTypeface(this, "font/font_file.ttf");
  }
}

And... you can also pass the font name as a string resource id:

public class MyActivity extends Activity {
  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.layout_activity_main);
    TypefaceHelper.getInstance().setTypeface(this, R.string.font_primary);
  }
}
