问题：
Android PendingIntent附加功能，未被BroadcastReceiver接收
张啸
当我将额外的内容传递给PendingIntent时，sendBroadcastRecencer永远不会接收到消息，因为从来没有调用过这个BroadcastRecencer的onAccess（）方法。为什么会发生这种情况？
public class MainActivity extends Activity {
private static String SENT = "SMS_SENT";
private static String DELIVERED = "SMS_DELIVERED";
private static int MAX_SMS_MESSAGE_LENGTH = 160;
private static Context mContext;
private BroadcastReceiver sendBroadcastReceiver, deliveryBroadcastReceiver;
private final String DEBUG_TAG = getClass().getSimpleName().toString();
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// ---when the SMS has been sent---
sendBroadcastReceiver = new BroadcastReceiver() {
public void onReceive(Context arg0, Intent arg1) {
switch (getResultCode()) {
case Activity.RESULT_OK:
Toast.makeText(getBaseContext(), "SMS Sent", Toast.LENGTH_SHORT).show();
break;
case SmsManager.RESULT_ERROR_GENERIC_FAILURE:
Toast.makeText(getBaseContext(), "Generic failure", Toast.LENGTH_SHORT).show();
break;
case SmsManager.RESULT_ERROR_NO_SERVICE:
Toast.makeText(getBaseContext(), "No service", Toast.LENGTH_SHORT).show();
break;
case SmsManager.RESULT_ERROR_NULL_PDU:
Toast.makeText(getBaseContext(), "Null PDU", Toast.LENGTH_SHORT).show();
break;
case SmsManager.RESULT_ERROR_RADIO_OFF:
Toast.makeText(getBaseContext(), "Radio off", Toast.LENGTH_SHORT).show();
break;
}
}
};
// ---when the SMS has been delivered---
deliveryBroadcastReceiver = new BroadcastReceiver() {
public void onReceive(Context arg0, Intent arg1) {
switch (getResultCode()) {
case Activity.RESULT_OK:
Toast.makeText(getBaseContext(), "SMS Delivered", Toast.LENGTH_SHORT).show();
break;
case Activity.RESULT_CANCELED:
Toast.makeText(getBaseContext(), "SMS not delivered",Toast.LENGTH_SHORT).show();
break;
}
}
};
Log.d(DEBUG_TAG, "onCreate() : Register receivers");
registerReceiver(deliveryBroadcastReceiver, new IntentFilter(DELIVERED));
registerReceiver(sendBroadcastReceiver, new IntentFilter(SENT));
mContext = getApplicationContext();
setContentView(R.layout.main);
// ... Bind views and set up onClick listeners ( for example, one to call sendSMS() )
}
@Override
protected void onDestroy() {
// Unregister receivers
Log.d(DEBUG_TAG, "onDestroy() : Unregister receivers");
if (sendBroadcastReceiver != null) {
unregisterReceiver(sendBroadcastReceiver);
sendBroadcastReceiver = null;
}
if (deliveryBroadcastReceiver != null) {
unregisterReceiver(deliveryBroadcastReceiver);
deliveryBroadcastReceiver = null;
}
super.onDestroy();
}
// ---sends an SMS message to another device---
public static void sendSMS(String phoneNumber, String message) {
Intent sendIntent = new Intent(SENT);
sendIntent.putExtra("extra_key", "extra_value"));
PendingIntent piSent = PendingIntent.getBroadcast(mContext, 0, sendIntent, PendingIntent.FLAG_UPDATE_CURRENT);
PendingIntent piDelivered = PendingIntent.getBroadcast(mContext, 0, new Intent(DELIVERED), 0);
SmsManager smsManager = SmsManager.getDefault();
int length = message.length();
if (length > MAX_SMS_MESSAGE_LENGTH) {
ArrayList < String > messagelist = smsManager.divideMessage(message);
smsManager.sendMultipartTextMessage(phoneNumber, null, messagelist, null, null);
} else
smsManager.sendTextMessage(phoneNumber, null, message, piSent, piDelivered);
}
}

我想在代码中注册和注销可能会有一些问题。相反，我在AndroidManifest中注册了两个文件，并且能够成功地传递额外信息。BroadcastReceivers。xml

我正在开发的一个应用程序允许用户自己读取确认短信的内容，输入验证码。对于使用早于Oreo（API 26）的操作系统的所有设备，BroadcastReceiver的实现工作正常，并允许正确接收SMS。在这个实现中，我的意思是将receiver对象放置在AndroidManifest中。 但是，从Oreo开始，必须显式地将BroadcastReceivers注册到适当的上下文。我对此执行如下： 在接收
