Android Horizontal ProgressBar Using Kotlin With Example

In this article, we will learn about android HorizontalProgressBar using Kotlin. We will go through various example that demonstrates how to use different attributes of HorizontalProgressBar. For example, …..

In this article, we will get answer to questions like –

  • What is HorizontalProgressBar?
  • Why should we consider HorizontalProgressBar while designing ui for any app?
  • What are possibilities using HorizontalProgressBar while designing ui? etc.

Let’s have a quick demo of things we want to cover in this tutorial –

Getting Started

We can define android HorizontalProgressBar widget as below –

Android ProgressBar is an user interface that represents progress of an operation. Here, Horizontal ProgressBar means progressBar as a horizontal line.

Now, how do we use HorizontalProgressBar in android application ?

Creating New Project

At first, we will create an application.
So, follow steps below to create any android project in Kotlin –

Step Description
1. Open Android Studio (Ignore if already done).
2. Go to File => New => New Project. This will open a new window. Then, under Phone and Tablet section, select Empty Activity. Then, click Next.
3. In next screen, select project name as HorizontalProgressBar. Then, fill other required details.
4. Then, clicking on Finish button creates new project.

Newbie in Android ?

Some very important concepts (Recommended to learn before you move ahead)

Before we move ahead, we need to setup for viewBinding to access Android HorizontalProgressBar Using Kotlin file without using findViewById() method.

Setup ViewBinding

Add viewBinding true in app/build.gradle file.

 
 android { 
 	// OTHER CODE... 
 	buildFeatures { 
 		viewBinding true 
 	} 
 } 
 

Now, set content in activity using view binding.
Open MainActivity.kt file and write below code in it.

 
 class MainActivity : AppCompatActivity() { 
 	
 	private lateinit var binding: ActivityMainBinding 
 	
 	override fun onCreate(savedInstanceState: Bundle?) { 
 		super.onCreate(savedInstanceState) 
 		binding = ActivityMainBinding.inflate(layoutInflater) 
 		val view = binding.root 
 		setContentView(view) 
 	} 
 } 
 

Now, we can access view in Kotlin file without using findViewById() method.

Using HorizontalProgressBar in Kotlin

Follow steps below to use HorizontalProgressBar in newly created project –

  • Open res/values/strings.xml file. Then, add below code into it.
    <resources>
        <string name="app_name">HorizontalProgressBar</string>
    </resources>
    
  • Open res/layout/activity_main.xml file. Then, add below code in it –
    <?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">
    
        <ProgressBar
            android:id="@+id/progressBar_ID"
            style="?android:attr/progressBarStyleHorizontal"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_margin="20dp"
            android:indeterminate="true"
            app:layout_constraintBottom_toBottomOf="parent"
            app:layout_constraintLeft_toLeftOf="parent"
            app:layout_constraintRight_toRightOf="parent"
            app:layout_constraintTop_toTopOf="parent" />
    
        <Button
            android:id="@+id/button_ID"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="HIDE PROGRESSBAR"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintStart_toStartOf="parent"
            app:layout_constraintTop_toBottomOf="@+id/progressBar_ID" />
    
    </androidx.constraintlayout.widget.ConstraintLayout>
    
  • We can also access it in Kotlin File, MainActivity.kt, as below –

    package com.tutorialwing.horizontalprogressbar
    
    import androidx.appcompat.app.AppCompatActivity
    import android.os.Bundle
    import android.view.View
    import com.tutorialwing.horizontalprogressbar.databinding.ActivityMainBinding
    
    class MainActivity : AppCompatActivity() {
    
    	private lateinit var binding: ActivityMainBinding
    
    	override fun onCreate(savedInstanceState: Bundle?) {
    		super.onCreate(savedInstanceState)
    		binding = ActivityMainBinding.inflate(layoutInflater)
    		val view = binding.root
    		setContentView(view)
    
    		setupProgressBar()
    	}
    
    	private fun setupProgressBar() {
    		val progressBar = binding.progressBarID
    		binding.buttonID.setOnClickListener {
    			val visibility = if (progressBar.visibility == View.GONE) View.VISIBLE else View.GONE
    			progressBar.visibility = visibility
    
    			val btnText =
    				if (progressBar.visibility == View.GONE) "SHOW PROGRESSBAR" else "HIDE PROGRESSBAR"
    			binding.buttonID.text = btnText
    		}
    	}
    }
    

Now, run the application. We will get output as below –

Different Attributes of HorizontalProgressBar in XML

Now, we will see how to use different attributes of Android HorizontalProgressBar using Kotlin to customise it –

Set Id of HorizontalProgressBar

Many a time, we need id of View to access it in kotlin file or create ui relative to that view in xml file. So, we can set id of HorizontalProgressBar using android:id attribute like below –

    <HorizontalProgressBar
        android:id="@+id/horizontalprogressbar_ID"
        />

Here, we have set id of HorizontalProgressBar as horizontalprogressbar_ID using android:id=”” attribute. So, if we need to reference this HorizontalProgressBar, we need to use this id – horizontalprogressbar_ID.

Set Width of HorizontalProgressBar

We use android:layout_width=”” attribute to set width of HorizontalProgressBar.
We can do it as below –

    <HorizontalProgressBar
        android:id="@+id/horizontalprogressbar_ID"
        android:layout_width="wrap_content"
        />

Width can be either “MATCH_PARENT” or “WRAP_CONTENT” or any fixed value (like 20dp, 30dp etc.).

Set Text in Uppercase, Lowercase

If we need to show text of HorizontalProgressBar in uppercase or lowercase etc.

Set text in uppercase

We can use android:textAllCaps=”true” attribute to set text in uppercase. We can do it as below –

    <HorizontalProgressBar
        android:id="@+id/horizontalprogressbar_ID"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Hello Tutorialwing"
        android:textAllCaps="true"
        />

Attribute android:textAllCaps=”true” sets text in uppercase. So, HELLO TUTORIALWING is set in HorizontalProgressBar.

By default, false is set in this attribute. So, Whatever value is written in android:text=”” attribute, it will be set as it is. For example,

    <HorizontalProgressBar
        android:id="@+id/horizontalprogressbar_ID"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Hello Tutorialwing"
        android:textAllCaps="false"
        />

Above code will set Hello Tutorialwing to HorizontalProgressBar.

How do we set text in lowercase?

Answer –

  • In xml file – write all the text in lowercase.
  • In kotlin file – take text as string. Then, convert it in lowercase. Then, set it to HorizontalProgressBar.
