In android, you can define your own custom fonts for the strings in your application. You just need to download the required font from the internet, and then place it in assets/fonts folder.

After putting fonts in the assets folder under fonts folder, you can access it in your java code through Typeface class. First , get the reference of the text view in the code. Its syntax is given below −

TextView tx = (TextView)findViewById(R.id.textview1);

The next thing you need to do is to call static method of Typeface class createFromAsset() to get your custom font from assets. Its syntax is given below −

Typeface custom_font = Typeface.createFromAsset(getAssets(), "fonts/font name.ttf");

The last thing you need to do is to set this custom font object to your TextView Typeface property. You need to call setTypeface() method to do that. Its syntax is given below −

tx.setTypeface(custom_font);

Apart from these Methods, there are other methods defined in the Typeface class , that you can use to handle Fonts more effectively.

Example

Here is an example demonstrating the use of Typeface to handle CustomFont. It creates a basic application that displays a custom font that you specified in the fonts file.

To experiment with this example, you can run this on an actual device or in an emulator.

Before entering to code part add fonts in assests folder from windows explorer.

Following is the content of the modified main activity file MainActivity.java.

package com.example.sairamkrishna.myapplication;

import android.graphics.Typeface;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.widget.TextView;

public class MainActivity extends ActionBarActivity {
   TextView tv1,tv2;

   protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);
         
      tv1=(TextView)findViewById(R.id.textView3);
      tv2=(TextView)findViewById(R.id.textView4);

      Typeface face= Typeface.createFromAsset(getAssets(), "font/font.ttf");
      tv1.setTypeface(face);

      Typeface face1= Typeface.createFromAsset(getAssets(), "font/font1.ttf");
      tv2.setTypeface(face1);
   }
}

Let”s try to run our Custom Font application we just modified. I assume you had created your AVD while doing environment setup. To run the app from Android studio, open one of your project”s activity files and click Run icon from the toolbar.Android studio installs the app on your AVD and starts it and if everything is fine with your setup and application, it will display following Emulator window −

As you can see that the text that appeared on the AVD has not a default android font, rather it has the custom font that you specified in the fonts folder.

Note − You need to take care of the size and the character supported by the font , when using custom fonts.
