在登录android应用程序之前，我想输入我的号码并按下按钮。这个按钮处理发送短信到号码进入，所以如果收到的消息给我，它将进入应用程序，否则它将显示一条消息，以验证/验证号码。

我找到了解决方案。使用BroadcastReceiver的onReceive方法

`

public void onReceive(Context context, Intent intent)
{
    //---get the SMS message passed in---
    Bundle bundle = intent.getExtras();
    if (bundle != null)
    {

    //---retrieve the SMS message received---
    Object[] pdus = (Object[]) bundle.get("pdus");
    msgs = SmsMessage.createFromPdu((byte[])pdus[0]);
     Log.i(TAG,  msgs.getMessageBody());
    Intent intent2 = new Intent("com.uba.messagereceived");
    str = "SMS From "+msgs.getOriginatingAddress()+":"+msgs.getMessageBody().toString()+"...";
    intent2.putExtra("letter", str);
    intent2.putExtra("address", msgs.getOriginatingAddress());
    intent2.putExtra("txt", msgs.getMessageBody().toString());
    context.sendBroadcast(intent2);

    } 
    //---display the new SMS message---
    Toast.makeText(context, str, Toast.LENGTH_SHORT).show();

if(yMsg == msgg &&  xNum == no)
    {
    setStatus("valid");
    Intent mp = new Intent(context,UserMainPage.class);
    context.startActivity(mp );
    Toast.makeText(context,"The Validation completed: "+this.getStatus(), Toast.LENGTH_SHORT).show();
    } 

else
    {
    setStatus("not Valid");
    Toast.makeText(context,"The Validation completed: "+this.getStatus(), Toast.LENGTH_SHORT).show();
    }

    }
