How to use custom font in a project written in Android Studio

Update 2021:

Create a folder named font inside the res folder and copy your font

All font names must be only: lowercase a-z, 0-9, or underscore.

        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:fontFamily="@font/abc_font" />

For programmatic use:

textView.setTypeface(ResourcesCompat.getFont(context, R.font.abc_font))

For Android Studio 4.2+ there's even now a menu option:

How to set custom font for a whole application in Android?

Write a class

public class MyApp extends Application{
// Put the onCreate code as you obtained from the post link you reffered
}

now next thing is in AndroidManifest.xml for the application tag give name for your application class. In this case it is MyApp

android:name=".MyApp"
...
>
...

So whenever the App is opened , onCreate method of MyApp class would be invoked , and the font would be set.

Update
Put font file under assets/fonts/your_font_file.ttf

Put this line under onCreate method of your application class(MyApp)

TypefaceUtil.overrideFont(getApplicationContext(), "SERIF", "fonts/your_font_file.ttf");

Source File for TypefaceUtil

public class TypefaceUtil {

    /**
     * Using reflection to override default typeface
     * NOTICE: DO NOT FORGET TO SET TYPEFACE FOR APP THEME AS DEFAULT TYPEFACE WHICH WILL BE OVERRIDDEN
     *
     * @param context                    to work with assets
     * @param defaultFontNameToOverride  for example "monospace"
     * @param customFontFileNameInAssets file name of the font from assets
     */
    public static void overrideFont(Context context, String defaultFontNameToOverride, String customFontFileNameInAssets) {

        final Typeface customFontTypeface = Typeface.createFromAsset(context.getAssets(), customFontFileNameInAssets);

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            Map newMap = new HashMap();
            newMap.put("serif", customFontTypeface);
            try {
                final Field staticField = Typeface.class
                        .getDeclaredField("sSystemFontMap");
                staticField.setAccessible(true);
                staticField.set(null, newMap);
            } catch (NoSuchFieldException e) {
                e.printStackTrace();
            } catch (IllegalAccessException e) {
                e.printStackTrace();
            }
        } else {
            try {
                final Field defaultFontTypefaceField = Typeface.class.getDeclaredField(defaultFontNameToOverride);
                defaultFontTypefaceField.setAccessible(true);
                defaultFontTypefaceField.set(null, customFontTypeface);
            } catch (Exception e) {
                Log.e(TypefaceUtil.class.getSimpleName(), "Can not set custom font " + customFontFileNameInAssets + " instead of " + defaultFontNameToOverride);
            }
        }
    }
}

Now update your style.xml file

put the below line your style which is included for your activity in manifest file

  serif

Hope this helps

How to apply custome fonts in android studio once for whole Project

THis is the answer which was posted by me on this Link. How to use custom font in Android Studio
Here we have a better way to apply fonts on EditTexts and TextViews on android at once and apply it in whole project.

First of All you need to make fonts folder. Here are Steps.

1: Go to the (project folder) Then app>src>main

2: Create folders named 'assets/fonts' into the main folder.

3: Put your fonts into the fonts folder. Here I Have 'MavenPro-Regular.ttf'

Here are the Steps for applying custom fonts on EditText and using this approach you can apply fonts on every input.

1 : Create a Class MyEditText (your preferred name ...)

2 : which extends EditText

3 : Apply your font

Here is code Example;

public class MyEditText extends EditText {

    public MyEditText(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        init();
    }

    public MyEditText(Context context, AttributeSet attrs) {
        super(context, attrs);
        init();
    }

    public MyEditText(Context context) {
        super(context);
        init();
    }

    private void init() {
        if (!isInEditMode()) {
            Typeface tf = Typeface.createFromAsset(getContext().getAssets(), "fonts/MavenPro-Regular.ttf");
            setTypeface(tf);
        }
    }

}

And in Here is the code how to use it.

MyEditText editText = (MyEditText) findViewById(R.id.editText);

editText.setText("Hello");

Or in Your xml File

    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center"
    android:textColor="#fff"
    android:textSize="16dp"
    android:id="@+id/editText"
    />

How to set custom font in .xml file instead of .java file?

For your reference,

 public class MyTextView extends TextView {

    public MyTextView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        init();
    }

    public MyTextView(Context context, AttributeSet attrs) {
        super(context, attrs);
        init();
    }

    public MyTextView(Context context) {
        super(context);
        init();
    }

    public void init() {
        Typeface tf = Typeface.createFromAsset(getContext().getAssets(), "font/yourfont.ttf");
        setTypeface(tf ,1);

    }
}

In XML,

         android:layout_width="wrap_content"
        android:layout_height="wrap_content"       
        android:textSize="20sp"
        android:text="Your text"
        />

How to use desired font in Image Asset in Android Studio?

According to the documentation

You can use the fonts that are installed on your computer.

So you should first install the font, then you should be able to see it in the selector.

Install a font on Mac

Install a font on Windows10

Edit: found a duplicate of your question

Android - Using Custom Font

On Mobiletuts+ there is very good tutorial on Text formatting for Android. Quick Tip: Customize Android Fonts

EDIT: Tested it myself now. Here is the solution. You can use a subfolder called fonts but it must go in the assets folder not the res folder. So

assets/fonts

Also make sure that the font ending I mean the ending of the font file itself is all lower case. In other words it should not be myFont.TTF but myfont.ttf this way must be in lower case
