接收短信时更改铃声配置文件

Question

你好，我是 Android 开发的新手我正在尝试制作一个在收到特定短信时更改铃声配置文件的应用程序，我也可以通过布局上的按钮更改它（按钮工作正常），但短信方式不起作用

我试过如下图

MainActivity.java

package com.example.test;
import android.media.AudioManager;
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,sms;
   public 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);
      sms = (TextView)findViewById(R.id.sms);

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

   }

   public void vibrate(View view){
       myAudioManager.setRingerMode(AudioManager.RINGER_MODE_VIBRATE);
   }
   public void ring(View view){
      myAudioManager.setRingerMode(AudioManager.RINGER_MODE_NORMAL);
   }
   public 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{

   }
  }
   public static void messageProcessing(String message) {
       if(message=="ring") 
           myAudioManager.setRingerMode(AudioManager.RINGER_MODE_NORMAL);
       else if (message=="vibrate")
           myAudioManager.setRingerMode(AudioManager.RINGER_MODE_VIBRATE);
       else if(message=="silent")
           myAudioManager.setRingerMode(AudioManager.RINGER_MODE_SILENT);

   }
   @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;
   }

}

RecieveSMS.java

package com.example.test;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.telephony.SmsMessage;
import android.widget.Toast;
import android.os.Bundle;

public class RecieveSMS extends BroadcastReceiver 
{   
    public static final String SMS_BUNDLE = "pdus";

    @Override
    public void onReceive(Context context, Intent intent) {

        Bundle intentExtras = intent.getExtras();
            if (intentExtras != null) {
                Object[] sms = (Object[]) intentExtras.get(SMS_BUNDLE);
                for (int i = 0; i < sms.length; ++i) {
                    SmsMessage smsMessage = SmsMessage.createFromPdu((byte[]) sms[i]);

                    String smsBody = smsMessage.getMessageBody().toString();

                    MainActivity.messageProcessing(smsBody);

                    Toast.makeText(context, smsBody, Toast.LENGTH_SHORT).show();
                }
            }
    }
}

有什么帮助吗？？另外，这个应用程序在后台运行，或者我应该提供服务来实现这一点？

我找到了解决问题的方法，就是这样:

package com.example.test;

import android.app.PendingIntent;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.telephony.SmsMessage;
import android.widget.Toast;
import android.media.AudioManager;
import android.os.Bundle;

public class RecieveSMS extends BroadcastReceiver 
{   
    public static final String SMS_BUNDLE = "pdus";

    @Override
    public void onReceive(Context context, Intent intent) {

        Bundle intentExtras = intent.getExtras();
            if (intentExtras != null) {
                Object[] sms = (Object[]) intentExtras.get(SMS_BUNDLE);
                for (int i = 0; i < sms.length; ++i) {
                    SmsMessage smsMessage = SmsMessage.createFromPdu((byte[]) sms[i]);

                    String smsBody = smsMessage.getMessageBody().toString();
                    //Edited from here
                    if (smsBody.contains("silent"))
                    {
                    Intent in = new Intent(context, MainActivity.class);
                    PendingIntent pendingIntent = PendingIntent.getActivity(context,
                    12345, in, PendingIntent.FLAG_CANCEL_CURRENT);
                    AudioManager am = (AudioManager)context.getSystemService(Context.AUDIO_SERVICE);
                    am.setRingerMode(AudioManager.RINGER_MODE_SILENT);
                    //To here
                    }

                    Toast.makeText(context, smsBody, Toast.LENGTH_SHORT).show();
                }
            }
    }
}
