解决方案

的广播接收器听的基础上的意图＆LT;意向滤光器＆gt; 。该数据过滤器不提供一种过滤你的要求，因为它并不在 SmsMessage.getMessage过滤器（）。你除了可以收听短信要做的就是扫描每封邮件的关键字，然后启动所需的活动。

How to set keyword to initiate Broadcast Receiver from text message? I got my Broadcast Receiver working, problem is it starts activity on receiving any text message and I just need it to start on receiving 1 or 2 keywords "Hotel and/or House" how do i do this .... Thank you. Below is my code

-manifest- " "

-actual receiver class- public class SMSReceiver extends BroadcastReceiver {

public void onReceive(Context context, Intent intent) {
    Bundle bundle = intent.getExtras();

    Object messages[] = (Object[]) bundle.get("pdus");
    SmsMessage smsMessage[] = new SmsMessage[messages.length];
    for (int n = 0; n < messages.length; n++) {
        smsMessage[n] = SmsMessage.createFromPdu((byte[]) messages[n]);
    }

    //show first message
    Toast toast = Toast.makeText(context, "Received SMS: " + smsMessage[0].getMessageBody(), Toast.LENGTH_LONG);
    toast.show();

    //and then start an activity

    Intent i = new Intent(context,AppActivity.class);
    i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    context.startActivity(i);   

解决方案

The BroadcastReceiver listens to Intents based on an <intent-filter>. The data filter doesn't provide kind of filtering you're asking for because it doesn't filter on SmsMessage.getMessage(). What you can do in addition to listening for an SMS is scan each message for the keyword and then start the desired activity.
