Question

我是Android的新手，我正在使用android 2.1进行一些sms_receive的事情：当收到短信时，它将无法工作......我有一个力量关闭，帮助！

public class SmsReceiverActivity extends Activity {
    private static final String SHORTCODE = "55443";
    public void onReceive(Context context, Intent intent) {
        Bundle bundle = intent.getExtras();
        Object[] messages = (Object[]) bundle.get("pdus");
        SmsMessage[] sms = new SmsMessage[messages.length];
        //Create messages for each incoming PDU
        for (int n = 0; n < messages.length; n++) {
            sms[n] = SmsMessage.createFromPdu((byte[]) messages[n]);
        }
        for (SmsMessage msg: sms) {
            //Verify if the message came from our known sender
            if (TextUtils.equals(msg.getOriginatingAddress(), "SHORTCODE")) {
                Toast.makeText(context, "Received message from the mothership: " + msg.getMessageBody(),Toast.LENGTH_SHORT).show();
            }
        }
}

android manifest：

<uses-sdk android:minSdkVersion="7" />
<uses-permission android:name="android.permission.RECEIVE_SMS"/>
 <application  android:label="@string/app_name">
    <activity
        android:name=".SmsReceiver"
        android:label="@string/app_name">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <receiver android:name=".SMSReceiver" android:enabled="true">
        <intent-filter android:priority="100">
            <action android:name="android.provider.Telephony.SMS_RECEIVED" />
        </intent-filter>
    </receiver>
</application>

在安装程序时我想运行它，我有一个强制关闭，这是我的LogCat：

Answer 1

我认为您需要在 Manifest.xml 中进行一些更改，例如：

 <receiver android:name=".SmsReceiver"> 
    <intent-filter android:priority="100">
        <action android:name="android.intent.action.PHONE_STATE" />
        <action android:name="PACKAGE_NAME.android.action.broadcast"/> 
         <action android:name="android.provider.Telephony.SMS_RECEIVED"></action>
    </intent-filter> 
</receiver>

将您的班级名称 SmsReceiverActivity 更改为 SmsReceiver ，您的班级也需要扩展 BroadcastReceiver 。
从这里了解如何做到这一点：

Answer 2

您需要BroadcastReceiver才能在应用中阅读短信。您可以使用以下内容。

public class SmsReceiver extends BroadcastReceiver {

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

        Object[] pdus = (Object[]) intent.getExtras().get("pdus");

        SmsMessage shortMessage = SmsMessage.createFromPdu((byte[]) pdus[0]);

        Log.i("sms received", "sms received");
        Log.i("SMS: ", shortMessage.getDisplayMessageBody());
    }
}

您还需要通过以下方式将其声明到您的应用程序中。

    <receiver android:name="YOUR_PACKAGE_NAME.SmsReceiver" >
        <intent-filter>
            <action android:name="android.provider.Telephony.SMS_RECEIVED" />
        </intent-filter>
    </receiver>

不要忘记添加与SMS相关的权限，例如以下

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