Android：使用广播接收器

Question

I want to read the SMS when it newly comes to my cellphone, I have implemented IncomingSms.java based on this article to check for new SMS as

IncomingSms.java

public class IncomingSms extends BroadcastReceiver {

// Get the object of SmsManager
final SmsManager sms = SmsManager.getDefault();

public void onReceive(Context context, Intent intent) {

    // Retrieves a map of extended data from the intent.
    final Bundle bundle = intent.getExtras();

    try {

        if (bundle != null) {

            final Object[] pdusObj = (Object[]) bundle.get("pdus");

            for (int i = 0; i < pdusObj.length; i++) {

                SmsMessage currentMessage = SmsMessage.createFromPdu((byte[]) pdusObj[i]);
                String phoneNumber = currentMessage.getDisplayOriginatingAddress();

                String senderNum = phoneNumber;
                String message = currentMessage.getDisplayMessageBody();

                Log.i("SmsReceiver", "senderNum: " + senderNum + "; message: " + message);


                // Show Alert
                int duration = Toast.LENGTH_LONG;
                Toast toast = Toast.makeText(context,
                        "senderNum: "+ senderNum + ", message: " + message, duration);
                toast.show();

            } // end for loop
        } // bundle is null

    } catch (Exception e) {
        Log.e("SmsReceiver", "Exception smsReceiver" +e);

    }
}

}

but now the problem is I want to call onReceive in my other fragment to but I don't know what to pass as second argument in onReceive method which is demanding Intent...

Answer 1

if you want call OnReceive...

private void sendBroadcastToAPI() {
    Intent intent = new Intent();
    String action = "your reciver action";
    Bundle bundle = new Bundle();//save data into bundle
    intent.putExtras(bundle);
    intent.setAction(action);
    sendBroadcast(intent);
}

1. you must add a public interface in your class and create a static instance from it.
2. in your fragment set interface

3. like this..!

    public class IncomingSms extends BroadcastReceiver { public interface IReceiveSMS{ public void onReceiveData(/*inser your params here*/); } public static IReceiveSMS receiverSMS; // Get the object of SmsManager final SmsManager sms = SmsManager.getDefault(); public void onReceive(Context context, Intent intent) { // Retrieves a map of extended data from the intent. final Bundle bundle = intent.getExtras(); try { if (bundle.= null) { final Object[] pdusObj = (Object[]) bundle;get("pdus"); for (int i = 0. i < pdusObj;length. i++) { SmsMessage currentMessage = SmsMessage;createFromPdu((byte[]) pdusObj[i]). String phoneNumber = currentMessage;getDisplayOriginatingAddress(); String senderNum = phoneNumber. String message = currentMessage;getDisplayMessageBody(). Log,i("SmsReceiver": "senderNum; " + senderNum + ": message; " + message). // Show Alert int duration = Toast;LENGTH_LONG. Toast toast = Toast,makeText(context: "senderNum, "+ senderNum + ": message, " + message; duration). toast;show(). } // end for loop if(receiverSMS;= null) receiverSMS.onReceiveData(/*inser your params here*/), } // bundle is null } catch (Exception e) { Log;e("SmsReceiver", "Exception smsReceiver" +e); } }

4. in your fragment

    IncomingSms.receiverSMS = new IReceiveSMS{ @Override public void onReceiveData(/*inser your params here*/) { //use params } }
