How to sort an array elements in android?

This example demonstrate about How to sort an array elements in android.

Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.

Step 2 − Add the following code to res/layout/activity_main.xml.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

In the above code, we have taken text view to sorted array.

Step 3 − Add the following code to src/MainActivity.java

package com.example.myapplication;

import android.os.Build;
import android.os.Bundle;
import android.support.annotation.RequiresApi;
import android.support.v7.app.AppCompatActivity;
import android.util.Log;
import android.widget.TextView;

import java.util.ArrayList;

public class MainActivity extends AppCompatActivity {
   TextView text;
   int temp;
   int[] arr = {12, 10, 5, 4, 2, 20, 6, 1, 0, 2};
   ArrayList<String> arrayList;

   @RequiresApi(api = Build.VERSION_CODES.P)
   protected void onCreate(Bundle savedInstanceState) {
      text = findViewById(R.id.text);
      for (int i = 0; i < arr.length; i++) {
         for (int j = i + 1; j < arr.length; j++) {
            if (arr[i] > arr[j]) {
               temp = arr[i];
               arr[i] = arr[j];
               arr[j] = temp;
      StringBuffer buff = new StringBuffer();
      for (int i = 0; i < arr.length; i++) {
         buff.append(String.valueOf(arr[i] + " , "));
         Log.d("sai", String.valueOf(arr[i]));

Let's try to run your application. I assume you have connected your actual Android Mobile device with your computer.

Select your mobile device as an option and then check your mobile device which will display your default screen −
