Change Fonts Typeface in Android Application:

Syntax to Change Android Fonts Typeface:

First initialize the Typeface variable-

Typeface typeface = Typeface.createFromAsset(getAssets(), "fonts/montserrat.otf");

Initialize your Android Button or TextView or anyother layout element of which you wish to change Font or Typeface

TextView txtInfo = (TextView) findViewById(R.id.txtInfo);
Button btnFonts = (Button) findViewById(R.id.btnFonts);

Now set your Font or typeface:

txtInfo.setTypeface(typeface);
btnFonts.setTypeface(typeface);

Here we will see complete working example of the above code implementation.

In your Android application, make a new layout file with name “home.xml” and edit it as following :

res>layout>home.xml:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#529de9">

<TextView
android:id="@+id/txtInfo"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerInParent="true"
android:padding="5dp"
android:text="Hello World!"
android:textColor="#fff"
android:textSize="40sp"
android:textStyle="bold"/>

<Button
android:id="@+id/btnFonts"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@+id/txtInfo"
android:layout_centerHorizontal="true"
android:layout_marginTop="5dp"
android:background="#fff"
android:padding="5dp"
android:text="Change Font"
android:textColor="#000" />
</RelativeLayout>

Make a new java class in your app package with name “Main.java” and edit it as following :

Main.java:

package com.example.h.myapplication;

import android.graphics.Typeface;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;

public class Main extends AppCompatActivity {
Typeface typeface;
TextView txtInfo;
Button btnFonts;
int k;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.home);
k = 1;
typeface = Typeface.createFromAsset(getAssets(), "fonts/montserrat.otf");
txtInfo = (TextView) findViewById(R.id.txtInfo);
btnFonts = (Button) findViewById(R.id.btnFonts);

txtInfo.setTypeface(typeface);
btnFonts.setTypeface(typeface);

btnFonts.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
ChangeFont(k++);
}
});
}

public void ChangeFont(int i) {
if (i > 5) {
i = 0;
k = i;
}

switch (i) {
case 0:
typeface = Typeface.createFromAsset(getAssets(), "fonts/greatvibes.otf");
break;
case 1:
typeface = Typeface.createFromAsset(getAssets(), "fonts/montserrat.otf");
break;
case 2:
typeface = Typeface.createFromAsset(getAssets(), "fonts/opensans.ttf");
break;
case 3:
typeface = Typeface.createFromAsset(getAssets(), "fonts/pacifico.ttf");
break;
case 4:
typeface = Typeface.createFromAsset(getAssets(), "fonts/raleway.ttf");
break;
case 5:
typeface = Typeface.createFromAsset(getAssets(), "fonts/roboto.ttf");
break;
}

txtInfo.setTypeface(typeface);
btnFonts.setTypeface(typeface);
}
}

I have placed my fonts into asset folder of my main folder of the project :

app > src > main > assets > fonts > all my fonts in this folder.

AndroidManisfest.xml:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.h.myapplication">

<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:roundIcon="@mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity
android:name=".Main"
android:label="@string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />

<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>

</manifest>

Now run your application and test the application.
