How to Change the Font Family of TextView in Android 😎

So, you want to change the fontFamily of a TextView in Android, huh? Well, you've come to the right place! In this guide, I'll show you how to select a different font for your TextView and provide easy solutions to common issues you may encounter along the way. Let's get started! 🚀

The Problem 😕

You mentioned that you don't see any pre-defined fonts in Android and you're not sure how to select one of them. You also mentioned that you don't need to define your own TypeFace, but simply want to use something different from the default font.

The Solution 💡

Here's what you can do to change the fontFamily of your TextView:

1. Step 1: Find a Pre-defined Font

   Android doesn't provide a wide range of pre-defined fonts out of the box. However, you can use external libraries or download fonts from reliable sources like Google Fonts. Let's say you want to use the "Roboto" font - a popular choice for Android apps. You can download it from here.

2. Step 2: Add the Font File to your Project

   Once you've downloaded the font file (usually in .ttf or .otf format), create a new directory in your project's res directory called font. Copy the font file to this directory.

3. Step 3: Define the Font in XML

   Open your layout file containing the TextView and add the following code snippet:

   <TextView android:id="@+id/HeaderText" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentTop="true" android:layout_centerHorizontal="true" android:layout_marginTop="52dp" android:gravity="center" android:text="CallerBlocker" android:textSize="40dp" android:fontFamily="@font/your_font_file_name" />

   Replace your_font_file_name with the actual name of the font file you added to the font directory. For example, if you downloaded the "Roboto-Regular.ttf" file, you would use android:fontFamily="@font/roboto_regular".

4. Step 4: Apply Changes and Test 🎉

   Save your layout file, rebuild your project, and run your app. The TextView should now be using the desired font.

Common Issues and Troubleshooting 🛠️

Issue 1: Font not applied or default font still used

• Double-check that you placed the font file in the correct location (res/font) and used the correct path in android:fontFamily.

• Ensure that the font file is properly formatted (e.g., .ttf or .otf).

• Verify that you spelled the font file name correctly, including case sensitivity.

Issue 2: Font file not recognized

• Make sure you have the necessary support library added to your project by checking your build.gradle file. Include the following line if it's missing:

  implementation 'androidx.legacy:legacy-support-v4:1.0.0'
