Java 如何为BroadcastReceiver扩展类传递值
我想将一些字符串值传递给我的all activity类。但我无法传递Broadcastreceiver类的值，因为它还扩展了Broadcastreceiver类。因此，我不能使用Intent或SharedReferences，也不能在此类中创建对象。我怎样才能得到这个类中的值Java 如何为BroadcastReceiver扩展类传递值,java,android,Java,Android,我想将一些字符串值传递给我的all activity类。但我无法传递Broadcastreceiver类的值，因为它还扩展了Broadcastreceiver类。因此，我不能使用Intent或SharedReferences，也不能在此类中创建对象。我怎样才能得到这个类中的值 public class SMSRecevir extends BroadcastReceiver { private BroadcastReceiver mReceiver = new BroadcastRec

传递值从何处到您的广播？我想将值FieldReass类传递给SMSReCeVIR类。您在广播接收器的开始还是在没有中间的地方发送？我想发送START。不工作…意图I =新意图（FrasLogLog.class，SMSReVeR.class），因为SMSRecevir.class不是一个活动，哪一行导致NULL？“android.provider.Telephony.SMS_RECEIVED”）……………..这一行
