为什么'；my ReceiveMessage.java类是否将SMS正文设置为my textview？
我在活动中有一个按钮。通过点击它，一条带有预定义正文和电话地址的短信被发送，然后一条包含代码的回复短信被自动发送到我的手机。我需要接收代码并将其设置为我的文本视图。我怎样才能解决它？我有两个活动：MainActivity和MessageReceiver为什么'；my ReceiveMessage.java类是否将SMS正文设置为my textview？,java,android,textview,sms,Java,Android,Textview,Sms,我在活动中有一个按钮。通过点击它，一条带有预定义正文和电话地址的短信被发送，然后一条包含代码的回复短信被自动发送到我的手机。我需要接收代码并将其设置为我的文本视图。我怎样才能解决它？我有两个活动：MainActivity和MessageReceiver //MessageReceiver.java public class MessageReceiver extends BroadcastReceiver { public void onReceive(Conte

您需要注册您的接收器 像这样：
getActivity().registerReceiver(intentReceiver, new IntentFilter("SMS_RECIEVED_ACTION"));
//MainActivity.java
private BroadcastReceiver intentReceiver; // do not set it up here. We'll set it and register it onCreate(), but we'll keep it here so it stays on scope of every other function
private IntentFilter intentFilter; // same for the filter
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// We'll set up the receiver here, after the activity starts
intentReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
TextView chargeText = (TextView) findViewById(R.id.chargeText);
Log.d("myTag", "is chargeText null? : " + (chargeText==null));
Log.d("myTag", "The text is: " + (intent.getExtras().getString("message")));
String text = intent.getExtras().getString("message").toString(); // let's try this with toString() so we are very explicit about it
Log.d("myTag", "The converted text is: " + text);
chargeText.setText(text);

- 您在onStart（）之前注册了一个接收器。该接收器适用于每种方法。但它没有注册
- 您正在onResume（）中创建一个新的接收器，其名称与前一个（broadcastReceiver）相同。您正确地注册了这个函数，但它超出了每个函数的范围
- 这意味着您试图访问一个未注册的接收者，并且您正在注册一个同名但超出范围的接收者
- 研究范围及其在面向对象编程中的工作方式
- 研究接受者、意图以及如何注册它们
祝你好运，朋友。在你的接收器中使用下面的代码
@Override
public void onReceive(Context context, Intent intent) {
final Bundle bundle = intent.getExtras();
try {
if (bundle != null) {
Object[] pdusObj = (Object[]) bundle.get("pdus");
for (Object aPdusObj : pdusObj) {
SmsMessage currentMessage = SmsMessage.createFromPdu((byte[]) aPdusObj);
String senderAddress = currentMessage.getDisplayOriginatingAddress();
String message = currentMessage.getDisplayMessageBody();
Log.d(TAG, "Received SMS: " + message + ", Sender: " + senderAddress);
// if the SMS is not from our gateway, ignore the message
if (!senderAddress.toLowerCase().contains(GlobalApplication.SMS_ORIGIN.toLowerCase())) {
return;
}
// verification code from sms
String verificationCode = getVerificationCode(message);
Log.d(TAG, "OTP received: " + verificationCode);
mListener.otpReceived(verificationCode);
}
}
} catch (Exception e) {
Log.e(TAG, "Exception: " + e.getMessage());
}
}
/**
* Getting the OTP from sms message body
* ':' is the separator of OTP from the message
*
* @param message
* @return
*/
private String getVerificationCode(String message) {
String str_msg = message.replace("Dear Customer,","");
str_msg = str_msg.replace("is your one time password (OTP). Please enter the OTP to proceed.","");
str_msg = str_msg.replace("Thank you,","");
str_msg = str_msg.replace("ChannelPaisa","");
str_msg = str_msg.replace("\n","");
str_msg= str_msg.trim().toString();
return str_msg;
}
谢谢不，没用。我收到短信，短信正文显示为祝酒词，但它没有在文本视图中设置。哦，我的糟糕。我以为你的问题是接收消息，而不是在文本视图上设置它。收到消息时，请检查空值和文本本身。我会更新我的帖子，让你看看如何更新。谢谢你的回答。但问题尚未解决。我编辑了我的问题并添加了我使用的全部代码。请看一下。看了你的代码后，我想你在注册接收者后定义了intentFilter。因此，接收器正在向空intentFilter注册。请你试着把它们按正确的顺序排列好吗？只是为了验证这个想法。能否尝试将所有内容（创建intentFilter、创建和注册接收者）都放在onResume（）中？谢谢。你的意思是我应该像onResume（）中编辑过的代码那样做吗？
