Question

你好，我是Android开发中的新手我试图制作一个可以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

我尝试如下所示

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();
                }
            }
    }
}

任何帮助？此外，这个应用程序在后台工作，或者我应该提供服务来实现这一目标？

我找到了解决问题的方法，以及如何：

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();
                }
            }
    }
}
