Demo:

1)MainActivity.java:

package com.venky.sortingarraylist;

import java.util.ArrayList;

import java.util.Collections;

import android.app.Activity;

import android.os.Bundle;

import android.widget.TextView;

public class MainActivity extends Activity {

      String value = "";

      TextView tv1, tv2;

      @Override

      protected void onCreate(Bundle savedInstanceState) {

            super.onCreate(savedInstanceState);

            setContentView(R.layout.activity_main);

            tv1 = (TextView) findViewById(R.id.textView1);

            tv2 = (TextView) findViewById(R.id.textView2);

            // Create and Add Values

            ArrayList<String> list = new ArrayList<String>();

            list.add("Welcome");

            list.add("Congrats");

            list.add("First");

            list.add("A");

            list.add("Z");

            list.add("G");

            tv1.setText("Data\n" + list.toString());

            // for sort the list

            Collections.sort(list);

            // set arrayList data

            tv2.setText("Sorted Data\n" + list.toString());

      }

}
