Android Studio for Textview, Font-Size

Introduction

Android Studio is an integrated development environment (IDE) designed specifically for developing Android applications. In this article, we will see how to use Android Studio to implement a Textview and change the font size.

Implementing Textview

First, let's create a new project in Android Studio.

1. Open Android Studio and click on "Create New Project"
2. Choose a project name, domain name and project location of your choice.
3. Once the project is created, open the "activity_main.xml" file located in the "res/layout" directory.
4. In the "activity_main.xml" file, add the following code to create a Textview:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">

    <TextView
        android:id="@+id/textview"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Hello World!" />

</RelativeLayout>

This code will create a Textview with the text "Hello World!".

Changing Font Size

To change the font size of the Textview, we need to add the following code to the "TextView" tag:

android:textSize="30sp"

This code will set the font size of the Textview to 30sp.

The final code for the "activity_main.xml" file will look like this:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">

    <TextView
        android:id="@+id/textview"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Hello World!"
        android:textSize="30sp" />

</RelativeLayout>
