Android Button – Text Color
To set Android Button text color, we can assign android:textColor XML attribute for Button in layout file with the required Color Value.
To programmatically set or change Android Button text color, we can pass specified color to the method Button.setTextColor(new_color).
In this tutorial, we will learn how to set or change the text color of Android Button, with the help of example application.

Set Android Button Text Color in Layout File
In this example project, we will change the Button text color in layout file using android:textColor XML attribute. The following is a step by step process.
Step 1
Open Android Studio and create an Android Project as shown in the following screenshot.

Step 2
Create Button widget in activity_main.xml. Set the text color of this Button widget using android:textColor attribute. In the following layout file, we have set the button text color to a value of "#00BCD4"
.
activity_main.xml
<?xml version="1.0" encoding="utf-8"?> <androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" tools:context=".MainActivity"> <Button android:id="@+id/myButton" android:text="Button" android:textColor="#00BCD4" android:layout_width="wrap_content" android:layout_height="wrap_content" app:layout_constraintLeft_toLeftOf="parent" app:layout_constraintRight_toRightOf="parent" app:layout_constraintTop_toTopOf="parent" /> </androidx.constraintlayout.widget.ConstraintLayout>
We may keep the MainActivity.kt to the default code.
MainActivity.kt
package com.example.myapplication import androidx.appcompat.app.AppCompatActivity import android.os.Bundle class MainActivity : AppCompatActivity() { override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) setContentView(R.layout.activity_main) } }
Step 3
Run this Android Application, and we would get the following output in the screen.

Step 4

Change Android Button Text Color Programmatically
In this example project, we will change the Button text color programmatically in MainActivity.kt program using Button.setTextColor(). The following is a step by step process.
Step 1
Open Android Studio and create an Android Project as shown in the following screenshot.

Step 2
Create Button widget in our main activity layout file as shown in the following acitivity_main.xml. Please note that we assigned an id myButton
. We shall use this id to get the reference to this Button in MainActivity.kt program.
activity_main.xml
<?xml version="1.0" encoding="utf-8"?> <androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" tools:context=".MainActivity"> <Button android:id="@+id/myButton" android:text="Button" android:layout_width="wrap_content" android:layout_height="wrap_content" app:layout_constraintLeft_toLeftOf="parent" app:layout_constraintRight_toRightOf="parent" app:layout_constraintTop_toTopOf="parent" /> </androidx.constraintlayout.widget.ConstraintLayout>
In MainActivity.kt program, we will get the reference to the Button using id, and set its text color to a new value Color.MAGENTA
using Button setTextColor() method.
MainActivity.kt
package com.example.myapplication import android.graphics.Color import androidx.appcompat.app.AppCompatActivity import android.os.Bundle import android.widget.Button class MainActivity : AppCompatActivity() { override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) setContentView(R.layout.activity_main) val button: Button = findViewById(R.id.myButton) button.setTextColor(Color.MAGENTA) } }
Step 3
Run this Android Application, and we would get the following output in the screen.

Step 4
