Question

我正在尝试编写程序，并且它的某些部分发送和接收消息。问题是，当我调用ReceiveSMS类时，它会给出这个错误：

android.content.ActivityNotFoundException：无法找到显式活动类{ir.hadisoft.paya / ir.hadisoft.paya.ReceiveSMS};你有没有在AndroidManifest.xml中声明这个活动？

这是我的receivems课程：

package ir.hadisoft.paya;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.widget.Toast;
import android.telephony.*;
import android.os.Bundle;

public class ReceiveSMS extends BroadcastReceiver {

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

        if(intent.getAction().equals("android.provider.Telephony.SMS_RECEIVED")) {
            android.util.Log.d("test","test");

            //--- Get the SMS message passed in ---
            Bundle bundle = intent.getExtras();
            SmsMessage[] msgs = null;
            String str = "";

            if (bundle != null)
            {
                //--- Retrieve the SMS message received ---
                Object[] pdus = (Object[]) bundle.get("pdus");
                msgs = new SmsMessage[pdus.length];
                for (int i=0; i<msgs.length; i++){
                    msgs[i] = SmsMessage.createFromPdu((byte[])pdus[i]);
                    str += "SMS from " + msgs[i].getOriginatingAddress();
                    str += " :";
                    str += msgs[i].getMessageBody().toString();
                    str += "\n";
                }
                //--- Display the new SMS message ---
                Toast.makeText(context, str, Toast.LENGTH_SHORT).show();
            }
        }
    }
}

这是我的manifest.xml：

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="ir.hadisoft.paya"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-permission android:name="android.permission.SEND_SMS"></uses-permission>
    <uses-permission android:name="android.permission.RECEIVE_SMS"></uses-permission>
    <uses-permission android:name="android.permission.READ_SMS" ></uses-permission>

    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >

        <activity
            android:name=".Paya"
            android:label="@string/title_activity_paya" >

            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

        <activity android:name=".Activation"></activity>

        <receiver android:name=".ReceiveSMS" android:enabled="true">
            <intent-filter>
                <action android:name="android.provider.Telephony.SMS_RECEIVED" >
                </action>
            </intent-filter>
        </receiver>
    </application>
</manifest>

这是sendms类：

            case R.id.btn_return_main:
                Intent intent1 = new Intent(Activation.this, Paya.class);
                startActivity(intent1);
                break;
            }
        }
    }

Answer 1

您的问题在于SendSMS类中的此代码：

Intent intent2=new Intent(Activation.this,ReceiveSMS.class);
startActivity(intent2);

接收者不是活动，因此您会收到例外情况 - 您根本无法将Receiver作为活动启动，它们不兼容。我甚至不认为这些行是必需的，因为如果您的应用正在运行，清单中声明的Receiver会自动收到短信。

Answer 2

更改

android:name=".ReceiveSMS"

到

android:name="ReceiveSMS"

此刻，您将自动将包装放在其前面，并带有圆点。由于它试图找到一个名为ReceiveSMS的Activity，其中没有。
