How to check edit text values are Anagram or Not in android?

This example demonstrate about How to check edit text values are Anagram or Not 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"
   xmlns:app="http://schemas.android.com/apk/res-auto"
   xmlns:tools="http://schemas.android.com/tools"
   android:layout_width="match_parent"
   android:gravity="center"
   android:layout_height="match_parent"
   tools:context=".MainActivity"
   android:orientation="vertical">
   <EditText
      android:id="@+id/edit_query"
      android:layout_width="match_parent"
      android:layout_height="wrap_content" />
   <EditText
      android:id="@+id/edit_query1"
      android:layout_width="match_parent"
      android:layout_height="wrap_content" />
   <Button
      android:id="@+id/buttonPanel"
      android:text="Button"
      android:layout_width="match_parent"
      android:layout_height="wrap_content"></Button>
</LinearLayout>

In the above code, we have taken two edit texts to take the data from the user and when user click on a button it will give the result on toast.

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.view.View;
import android.widget.EditText;
import android.widget.TextView;
import android.widget.Toast;

import java.util.ArrayList;

public class MainActivity extends AppCompatActivity {
   EditText edit_query1,edit_query;
   String first,second;
   int found = 0, not_found = 0;
   @RequiresApi(api = Build.VERSION_CODES.P)
   @Override
   protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);
      edit_query1=findViewById(R.id.edit_query1);
      edit_query=findViewById(R.id.edit_query);
      findViewById(R.id.buttonPanel).setOnClickListener(new View.OnClickListener() {
         @Override
         public void onClick(View v) {
            if(!edit_query.getText().toString().isEmpty() && !edit_query1.getText().toString().isEmpty()) {
               first = edit_query.getText().toString().trim();
               second = edit_query1.getText().toString().trim();
            }
            char[] firstchar=first.toCharArray();
            char[] secondchar=second.toCharArray();
            for(int i = 0;i<firstchar.length;i++) {
               found = 0;
               for(int j = 0;j<secondchar.length;j++){
                  if(firstchar[i] == secondchar[j]) {
                     found = 1;
                     break;
                  }
               }
               if(found == 0) {
                  not_found = 1;
                  break;
               }
            }
            if(not_found == 1) {
               Toast.makeText(MainActivity.this,"it is not anagaram",Toast.LENGTH_LONG).show();
            } else {
               Toast.makeText(MainActivity.this,"it is anagaram",Toast.LENGTH_LONG).show();
            }
         }
      });
   }
}

Let's try to run your application. I assume you have connected your actual Android Mobile device with your computer. To run the app from android studio, open one of your project's activity files and click Run  icon from the toolbar. Select your mobile device as an option and then check your mobile device which will display your default screen −
