Android Application To Set Silent Mode, Ringer Mode, And Vibrate Mode In A Phone

Introduction

Android is one of the most popular operating systems for mobile. In this article, I will show you how to create an application which can be used to set silent mode, ringer mode, and vibrate mode in your Android phone. 

Requirements

• Android Studio version 2.3.3
• Little bit XML and Java knowledge.
• Android Emulator (or) Android mobile
• Download link (Android Studio)

Steps should be followed

Follow these steps to build the app. I have included the source code below.

Step 1

Open Android Studio and start a new Android Studio Project.

Step 2

You can choose your application name and choose where your project is stored on the location. If you wish to use C++ for coding the project, mark the "Include C++ support", and click "Next" button.

Now, select the version of Android and select the target Android devices.

Step 3

Now, add the activity and click "Next" button.

Add Activity name and click "Finish".

Step 4

Go to activity_main.xml. This XML file contains the designing code for Android app.

The XML code is given below.

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="abu.myapplication.MainActivity" >
   <TextView
      android:id="@+id/textView1"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:text="ringer app" />

   <Button
      android:id="@+id/button1"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:layout_below="@+id/textView1"
      android:layout_marginTop="15dp"
      android:layout_toRightOf="@+id/textView1"
      android:text="silent" />
   <Button
      android:id="@+id/button2"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:layout_alignLeft="@+id/button1"
      android:layout_marginTop="98dp"
      android:text="vibrate" />

   <Button
      android:id="@+id/button3"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:layout_alignLeft="@+id/button2"
      android:layout_below="@+id/button2"
      android:layout_marginTop="30dp"
      android:text="ringer" />
</RelativeLayout>

Step 5

Go to Main Activity.java. This Java program is the backend language for Android.

The java code is given below.

package abu.myapplication;
import android.media.AudioManager;
import android.os.Bundle;
import android.provider.MediaStore.Audio;
import android.app.Activity;
import android.content.Context;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class MainActivity extends Activity {
    Button b1, b2, b3;
    AudioManager am;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        b1 = (Button) findViewById(R.id.button1);
        b2 = (Button) findViewById(R.id.button2);
        b3 = (Button) findViewById(R.id.button3);
        am = (AudioManager) getSystemService(Context.AUDIO_SERVICE);
        b1.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                am.setRingerMode(0);
            }
        });
        b2.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                am.setRingerMode(1);
            }
        });
        b3.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                am.setRingerMode(2);
            }
        });
    }
}

Step 6

Now, go to menu bar and click "Make Project" or press ctrl+f9 to debug the error.

Step 7

Then, click "Run" button or press shift+f10 to run the project. Choose the virtual machine and click OK.

Conclusion

We have successfully created the application to set silent mode, ringer mode, vibrate mode in Android.
