Android SeekBar Kotlin

Here is the tutorial for Java

Below is a simple example of using SeekBar in an Android application using Java. The example includes a SeekBar and a TextView to display the progress:

There Are Some Common Attributes for SeekBar :

Step 1:
Layout Open your layout XML file (e.g., activity_main.xml) and add the following code to include a Switch widget:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 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">

    <SeekBar
        android:id="@+id/seekBar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_centerVertical="true"
        android:layout_marginStart="16dp"
        android:layout_marginEnd="16dp" />

    <TextView
        android:id="@+id/progressTextView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@id/seekBar"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="16dp"
        android:text="Progress: 0" />
</RelativeLayout>

Step 2:

File open com.microappvalley.newtestproject/MainActivity.kt file −:

package com.microappvalley.newtestproject

import android.annotation.SuppressLint
import android.graphics.BitmapFactory
import androidx.appcompat.app.AppCompatActivity
import android.os.Bundle
import android.webkit.WebChromeClient
import android.webkit.WebView
import android.webkit.WebViewClient
import android.widget.Button
import android.widget.ImageView
import android.widget.SeekBar
import android.widget.Switch
import android.widget.TextView
import android.widget.Toast

class MainActivity : AppCompatActivity() {
    private lateinit var webView: WebView
    private lateinit var seekBar: SeekBar
    private lateinit var progressTextView: TextView
    @SuppressLint("MissingInflatedId")
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
        // Find the WebView by its id
        seekBar = findViewById(R.id.seekBar)
        progressTextView = findViewById(R.id.progressTextView)

        // Set the maximum progress for the SeekBar (default is 100)
        seekBar.max = 100

        // Set a listener to track changes in SeekBar progress
        seekBar.setOnSeekBarChangeListener(object : SeekBar.OnSeekBarChangeListener {
            override fun onProgressChanged(seekBar: SeekBar?, progress: Int, fromUser: Boolean) {
                // Update the TextView with the current progress
                progressTextView.text = "Progress: $progress"
            }

            override fun onStartTrackingTouch(seekBar: SeekBar?) {
                // Not needed for this example

            }

            override fun onStopTrackingTouch(seekBar: SeekBar?) {
                // Not needed for this example
                
            }
        })


    }
}

Open Device Manager, run the emulator, and  then run the application. Next, check the working output and check the output  you declared in your code.
