Question

我经常尝试和搜索并实施但是我没有得到结果。一旦新的SMS消息到来，我试图通过使用广播接收器在吐司上显示。但是，不给出结果。
我正在尝试使用此代码，

BroadcastReceiver类

public class MainActivity extends BroadcastReceiver{
@SuppressLint("NewApi")
@Override

    public void onReceive(Context context, Intent intent) {
        Bundle myBundle = intent.getExtras();
        SmsMessage [] messages = null;
        String strMessage = "";
        if (myBundle != null)
        {
            Object [] pdus = (Object[]) myBundle.get("pdus");
            messages = new SmsMessage[pdus.length];
            for (int i = 0; i < messages.length; i++)
            {
                messages[i] = SmsMessage.createFromPdu((byte[]) pdus[i]);
                strMessage += "SMS From: " + messages[i].getOriginatingAddress();
                strMessage += " : ";
                strMessage += messages[i].getMessageBody();
                strMessage += "\n";
            }
            Toast.makeText(context, strMessage, Toast.LENGTH_SHORT).show();
        }
    }
}

的manifest.xml

 <manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.websoftexmessagetracker"
    android:versionCode="1"
    android:versionName="1.0" >
    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="19" />
    <uses-permission android:name="android.permission.RECEIVE_SMS" />
    <uses-permission android:name="android.permission.READ_SMS" />
    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <receiver android:name=".MainActivity" >
            <intent-filter>
                <action android:name="android.provider.Telephony.SMS_RECEIVED" />
            </intent-filter>
        </receiver>
    </application>
</manifest>

请帮我解决这个问题。我没有得到再次需要的东西，以便它可以工作.. 提前致谢.. 请帮助我...

您是否将此代码添加到清单？

注意：在清单文件中添加BroadcastReceiver -

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

添加此权限：

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

更新：

将您的代码更改为：

@Override
    public void onReceive(Context context, Intent intent) {
        // TODO Auto-generated method stub

        if(intent.getAction().equals("android.provider.Telephony.SMS_RECEIVED")){
            Bundle bundle = intent.getExtras();           //---get the SMS message passed in---
            SmsMessage[] msgs = null;
            String msg_from;
            if (bundle != null){
                //---retrieve the SMS message received---
                try{
                    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]);
                        msg_from = msgs[i].getOriginatingAddress();
                        String msgBody = msgs[i].getMessageBody();
                    }
                }catch(Exception e){
//                            Log.d("Exception caught",e.getMessage());
                }
            }
        }
    }
