AndroidMobile DevelopmentApps/Applications

This example demonstrate about How to find edit text values start from consonant or not.

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:hint="Enter something"
      android:layout_height="wrap_content" />
   <Button
      android:id="@+id/buttonPanel"
      android:text="Click"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content" />
</LinearLayout>

In the above code, we have taken edit text and button view to verify edit text data is starting with a consonant.

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

package com.example.myapplication;

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.EditText;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity {
   @Override
   protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);
      final EditText edit_query = findViewById(R.id.edit_query);
      findViewById(R.id.buttonPanel).setOnClickListener(new View.OnClickListener() {
         @Override
         public void onClick(View v) {
            String data = edit_query.getText().toString();
            if (!data.isEmpty()) {
               data = data.substring(0, 1);
               if (data.equals("a") || data.equals("e") || data.equals("i") || data.equals("o") || data.equals("u"))
                  Toast.makeText(MainActivity.this, data + " is vowel", Toast.LENGTH_LONG).show();
               else
                  Toast.makeText(MainActivity.this, data + " is consonant", Toast.LENGTH_LONG).show();
            }
         }
      });
   }
}
