import android.os.Bundle;
import android.app.Activity;
import android.content.Context;
import android.view.Menu;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;


public class MainActivity extends Activity {

  private Button Vibrate , Ring , Silent , Mode;
  private TextView Status;
  private static AudioManager myAudioManager;
  @Override
  protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);


      Vibrate = (Button)findViewById(R.id.button2);
      Ring = (Button)findViewById(R.id.button4);
      Silent = (Button)findViewById(R.id.button3);
      Mode = (Button)findViewById(R.id.button1);
      Status = (TextView)findViewById(R.id.textView2);

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

  }

  public static void vibrate(View view){
      myAudioManager.setRingerMode(AudioManager.RINGER_MODE_VIBRATE);
  }
  public static void ring(View view){
      myAudioManager.setRingerMode(AudioManager.RINGER_MODE_NORMAL);
  }
  public static void silent(View view){
      myAudioManager.setRingerMode(AudioManager.RINGER_MODE_SILENT);
  }
  public void mode(View view){
    int mod = myAudioManager.getRingerMode();
    if(mod == AudioManager.RINGER_MODE_NORMAL){
        Status.setText("Current Status: Ring");
  }
  else if(mod == AudioManager.RINGER_MODE_SILENT){
      Status.setText("Current Status: Silent");
  }
  else if(mod == AudioManager.RINGER_MODE_VIBRATE){
      Status.setText("Current Status: Vibrate");
  }
  else{

  }
}
  @Override
  public boolean onCreateOptionsMenu(Menu menu) {
      // Inflate the menu; this adds items to the action bar if it is present.
      getMenuInflater().inflate(R.menu.main, menu);
      return true;
  }

}

Code:

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.telephony.SmsMessage;
import android.view.View;



public class RecieveSMS extends BroadcastReceiver
{
        private static final String ACTION_SMS_RECEIVED = "android.provider.Telephony.SMS_RECEIVED";
        private Context mContext;
        private Intent mIntent;
    @Override
    public void onReceive(Context context, Intent intent) {
        mContext = context;
        mIntent = intent;

        String action = intent.getAction();

        if(action.equals(ACTION_SMS_RECEIVED)){

            String str = "";
            View v = null;
            /* Get all messages contained in the Intent*/
            SmsMessage[] msgs = getMessagesFromIntent(mIntent);
            if (msgs != null) {
                for (int i = 0; i < msgs.length; i++) {
                    str += msgs[i].getMessageBody().toString();
                }
                if(str=="ring")
                        MainActivity.ring(v);
                else if (str=="vibrate")
                        MainActivity.vibrate(v);
                else if(str=="silent")
                        MainActivity.silent(v);
            } 

            // ---send a broadcast intent to update the SMS received in the
            // activity---
            Intent broadcastIntent = new Intent();
            broadcastIntent.setAction("SMS_RECEIVED_ACTION");
            context.sendBroadcast(broadcastIntent);
        }

    }

    public static SmsMessage[] getMessagesFromIntent(Intent intent) {
        Object[] messages = (Object[]) intent.getSerializableExtra("pdus");
        byte[][] pduObjs = new byte[messages.length][];

        for (int i = 0; i < messages.length; i++) {
            pduObjs[i] = (byte[]) messages[i];
        }
        byte[][] pdus = new byte[pduObjs.length][];
        int pduCount = pdus.length;
        SmsMessage[] msgs = new SmsMessage[pduCount];
        for (int i = 0; i < pduCount; i++) {
            pdus[i] = pduObjs[i];
            msgs[i] = SmsMessage.createFromPdu(pdus[i]);
        }
