You can easily control your ringer volume and ringer profile i-e:(silent,vibrate,loud e.t.c) in android. Android provides AudioManager class that provides access to these controls.

In order to use AndroidManager class, you have to first create an object of AudioManager class by calling the getSystemService() method. Its syntax is given below.

private AudioManager myAudioManager;
myAudioManager = (AudioManager)getSystemService(Context.AUDIO_SERVICE);  

Once you instantiate the object of AudioManager class, you can use setRingerMode method to set the audio or ringer profile of your device. Its syntax is given below.

myAudioManager.setRingerMode(AudioManager.RINGER_MODE_VIBRATE);

The method setRingerMode takes an integer number as a parameter. For each mode , an integer number is assigned that will differentiate between different modes. The possible modes are.

Once you have set the mode , you can call the getRingerMode() method to get the set state of the system. Its syntax is given below.

int mod = myAudioManager.getRingerMode();

Apart from the getRingerMode method, there are other methods available in the AudioManager class to control the volume and other modes. They are listed below.

Example

The below example demonstrates the use of AudioManager class. It creates a application that allows you to set different ringer modes for your device.

To experiment with this example , you need to run this on an actual device.

Here is the content of src/MainActivity.java

package com.example.sairamkrishna.myapplication;

         }
      });

      ring.setOnClickListener(new View.OnClickListener() {

                  Toast.LENGTH_LONG).show();
            } else if(mod==AudioManager.RINGER_MODE_NORMAL){
               Toast.makeText(MainActivity.this,"Now in Ringing Mode",
                  Toast.LENGTH_LONG).show();
            } else {
               Toast.makeText(MainActivity.this,"Now in Vibrate Mode",
                  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 tool bar. Android studio will display Images

Now select silent button, you would get silent icon at Notification bar

Now just select the ring button and then press the current mode button to see that if its status has been set.

Now press the Vibrate button and then press the current mode button to see that if it is set or not.It will display the following screen.
