Set Volume Mode, Vibrate Mode, And Silent Mode To On/Off In Android Studio

Introduction

In this article, you will learn how to develop or set volume mode, vibrate mode, and silent mode to ON/OFF in Android applications, using Android Studio.

Requirements

Android Studio version 2.1.3

If you want to create volume, vibrate, and silent mode in switch control, follow the below steps.

Step 1

Open Android Studio and choose File >> New >> NewProject.

Step 2

Here, enter your application name and select the location where your project should be stored. Then, click the NEXT button.

Now, select the minimum version of Android for which you want to target the Android Devices.

Step 3

On the next screen, add the activity of your choice, Empty in our case, and click the Next button.

Now, we write the activity name and click Finish.

Step 4

Now, open your project and go to activity_main.xml. Afterward, build the design with the help of drag and drop method, like dragging the Switch and Button tools .

Now, we can see the Graphical User Interface design.

Step 5

Now, go to the source panel and write the XML code.

Activity_mai.xml code

<?xml version="1.0" encoding="utf-8"?>
<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" android:paddingBottom="@dimen/activity_vertical_margin" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" tools:context="xyz.rvconstructions.www.switchonoffapp.MainActivity">
<Switch android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Volume" android:id="@+id/vlm" android:layout_alignParentTop="true" android:layout_alignParentLeft="true" android:layout_alignParentStart="true" />
<Switch android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Silent" android:id="@+id/slt" android:layout_below="@+id/vlm" android:layout_alignParentLeft="true" android:layout_alignParentStart="true" />
<Switch android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Vibrate" android:id="@+id/vbt" android:layout_below="@+id/slt" android:layout_alignParentLeft="true" android:layout_alignParentStart="true" />
<Button android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Submit" android:id="@+id/button" android:layout_centerVertical="true" android:layout_centerHorizontal="true" />
</RelativeLayout>

Step 6

Now, go to MainActivity.java page and build the Java code.

First, you need to declare an extension file.

Below, we can see the MainActivity.java code.

package xyz.rvconstructions.www.switchonoffapp;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.Button;
import android.widget.Switch;
import android.widget.Toast;
public class MainActivity extends AppCompatActivity {
Switch Switch1, Switch2, Switch3;
Button submit;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Switch1 = (Switch) findViewById(R.id.vlm);
Switch2 = (Switch) findViewById(R.id.slt);
Switch3 = (Switch) findViewById(R.id.vbt);
submit = (Button) findViewById(R.id.button);
submit.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
String statusSwitch1, statusSwitch2, statusSwitch3;
if (Switch1.isChecked())
statusSwitch1 = Switch1.getTextOn().toString();
else
statusSwitch1 = Switch1.getTextOff().toString();
if (Switch2.isChecked())
statusSwitch2 = Switch2.getTextOn().toString();
else
statusSwitch2 = Switch2.getTextOff().toString();
if (Switch3.isChecked())
statusSwitch3 = Switch3.getTextOn().toString();
else
statusSwitch3 = Switch2.getTextOff().toString();
Toast.makeText(getApplicationContext(), "Volume :" + statusSwitch1 + "\n" + "Silent :" + statusSwitch2 + "\n" + "Vibrate :" + statusSwitch3, Toast.LENGTH_LONG).show(); // display the current state for switch's
}
});
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.action_bar) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
