接收短信无法正常工作（java android）

Question

我不明白，当我收到短信时，没有任何内容出现。

public class MyReceiver extends BroadcastReceiver {
    public MyReceiver() {
    }

    private static final String RECEIVE_MSG = "android.provider.Telephony.SMS_RECEIVED";

    @Override
    public void onReceive(Context context, Intent intent) {

        if(intent.getAction().equals(RECEIVE_MSG)){
            Bundle extra = intent.getExtras();
            if(extra!= null){
                Object[] pdus = (Object[])extra.get("pdus");
                final SmsMessage[] messages = new SmsMessage[pdus.length];
                for(int i = 0; i<pdus.length; i++){
                    messages[i]= SmsMessage.createFromPdu((byte[])pdus[i]);
                }
                if (messages.length>-1) {
                    for (int i = 0; i<messages.length; i++) {
                        final String messageBody = messages[i].getMessageBody();
                        final String phoneNumber = messages[i].getDisplayOriginatingAddress();
                        Toast.makeText(context,"Expéditeur:" + phoneNumber, Toast.LENGTH_LONG).show();
                        Toast.makeText(context,"Message : " + messageBody, Toast.LENGTH_LONG).show();
                    }
                }
            }
        }

    }
}

您是在清单或活动中注册了reicever吗？

<receiver android:name=".broadcast.SmsBroadcastReceiver" >
        <intent-filter android:priority="5000">
            <action android:name="android.provider.Telephony.SMS_RECEIVED"/>
        </intent-filter>

</receiver>

或

 IntentFilter filter = new IntentFilter("android.provider.Telephony.SMS_RECEIVED");
 filter.setPriority(9999);
 registerReceiver(new SmsBroadcastReceiver(),filter);
