如果我向某人发送一条短信,上面写着“更新”。所以我可以得到那个人的位置。我将制作一个广播接收器,它会在任何短信到达时处于活动状态。如果它与 UPDATE 匹配,则将发送其他用户的位置。
广播接收器。
public void onReceive(Context context, Intent intent) 
{   
//this stops notifications to others
this.abortBroadcast();
//---get the SMS message passed in---
Bundle bundle = intent.getExtras();   
SmsMessage[] msgs = null;
String str = "";            
if (bundle != null)
{
//---retrieve the SMS message received---
Object[] pdus = (Object[]) bundle.get("pdus");
msgs = new SmsMessage[pdus.length];            
for (int i=0; i<msgs.length; i++){
    msgs[i] = SmsMessage.createFromPdu((byte[])pdus[i]);                
    str += "SMS from " + msgs[i].getOriginatingAddress();
    from = msgs[i].getOriginatingAddress();
    str += " :";
    str += msgs[i].getMessageBody().toString();
    msg = msgs[i].getMessageBody().toString();
    str += "\n"; 
}
if(checksomething){
    //make your actions
    //and no alert notification and sms not in inbox
}
else{
    //continue the normal process of sms and will get alert and reaches inbox
    this.clearAbortBroadcast();
}
  }
