How to set custom font for a whole application in

Question

Is it possible to set a custom font in an Android application?

I tried what is posted here, but I don't know where my extends Application class is...

Any help?

EDIT:

I tried the following:

• Add an assets folder and insert the font inside as seen here:

• Add a new class that extends from Application

• Call this new class from my AndroidManifest.xml.

• I went to my style and added it.

MyApp.java:

public class MyApp extends Application {
  @Override
  public void onCreate() {
     super.onCreate();
    FontsOverride.setDefaultFont(this, "DEFAULT", "raleway_regular.ttf");
    //  This FontsOverride comes from the example I posted above
  }
  }

AndroidManifest.xml:

<application
      android:allowBackup="true"
      android:icon="@mipmap/ic_launcher"
      android:label="@string/app_name"
      android:supportsRtl="true"
      android:name=".MyApp"
      android:theme="@style/AppTheme">
     ....

styles.xml:

 <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <item name="android:fontFamily">default</item>
 </style>

But my font is still not changning... any idea?

Then the MyApp class is called. But no effect on my fonts...

EDIT2: I realized that my buttons apply the custom font after I set a custom style for my buttons. Here is my custom button style:

<style name="MyButtonStyle" parent="Widget.AppCompat.Button">
    <item name="textAllCaps">false</item>
    <item name="android:textAllCaps">false</item>
</style>

And here is how it looks now:

So: my button is applying the style, but not the TextView. Any idea on why my custom font is not being applied for all items in application?

Try below code, it works for me, Hope it'll help you too.

public class BaseActivity extends AppCompatActivity {

private Typeface typeace;
@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    typeace = Typeface.createFromAsset(getAssets(), getResources().getString(R.string.font_name));
}

@Override
protected void onStart() {
    // TODO Auto-generated method stub
    super.onStart();
    overrideFonts(this,getWindow().getDecorView());
}

private void overrideFonts(final Context context, final View v) {
    try {
        if (v instanceof ViewGroup) {
            ViewGroup vg = (ViewGroup) v;
            for (int i = 0; i < vg.getChildCount(); i++) {
                View child = vg.getChildAt(i);
                overrideFonts(context, child);
         }
        } else if (v instanceof TextView) {
            ((TextView) v).setTypeface(typeace);
        } else if (v instanceof EditText ) {
            ((EditText) v).setTypeface(typeace);
        } else if (v instanceof Button) {
            ((Button) v).setTypeface(typeace);
        }
    } catch (Exception e) {
 }
 }
}

Now extend this BaseActivity to any of your Activity or you can create same class for fragment if you are using.

Note:- If you want to set some of the view different typeface then you have to set that programmatically as below

private Typeface typeface;
typeface = Typeface.createFromAsset(getAssets(), getResources().getString(R.string.font_name_bold));
tvUserName.setTypeface(typeface);

So give it a try and let me know, If I could help you further
