我正在制作一个应用程序,用于监听所有传入的SMS消息并将其安全地发送到我的服务器上的数据库。我还想发送所有传入的SMS消息的显示名称,完成此操作的最佳方法是什么?是否有一种方法我可以用传入的消息来做到这一点,或者是实现这一目标的唯一方法是创建一个函数,该函数将搜索我的联系人与smsMessage [0] .getOriginatingAddress()相同的号码, 。这里是我的功能,我发现和我进来的消息代码:如何仅通过电话号码获取联系人姓名?

public class SMSReceiver extends BroadcastReceiver { 
@Override 
public void onReceive(Context context, Intent intent) { 
    Bundle bundle = intent.getExtras(); 

    Object messages[] = (Object[]) bundle.get("pdus"); 
    SmsMessage smsMessage[] = new SmsMessage[messages.length]; 
    for (int n = 0; n < messages.length; n++) { 
     smsMessage[n] = SmsMessage.createFromPdu((byte[]) messages[n]); 
    } 

    // show first message 
    HttpClient httpclient = new DefaultHttpClient(); 
    HttpPost httppost = new HttpPost("http://www.qas.im/web/add_sms.php"); 

    try { 
     // Add your data 
     List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2); 
     nameValuePairs.add(new BasicNameValuePair("from", smsMessage[0].getOriginatingAddress())); 
     nameValuePairs.add(new BasicNameValuePair("msg", smsMessage[0].getMessageBody())); 
     httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs)); 

     // Execute HTTP Post Request 
     httpclient.execute(httppost); 
    } catch (ClientProtocolException e) {} catch (IOException e) {} 
    Toast toast = Toast.makeText(context, "Sent to Server \n\n" + smsMessage[0].getMessageBody(), Toast.LENGTH_LONG); 
    toast.show(); 
} 

public String getContactName(final String phoneNumber) 
{ 
    Uri uri; 
    String[] projection; 

    if (Build.VERSION.SDK_INT >= 5) 
    { 
     uri = Uri.parse("content://com.android.contacts/phone_lookup"); 
     projection = new String[] { "display_name" }; 
    } 
    else 
    { 
     uri = Uri.parse("content://contacts/phones/filter"); 
     projection = new String[] { "name" }; 
    } 

    uri = Uri.withAppendedPath(uri, Uri.encode(phoneNumber)); 
    Cursor cursor = this.getContentResolver().query(uri, projection, null, null, null); 

    String contactName = ""; 

    if (cursor.moveToFirst()) 
    { 
     contactName = cursor.getString(0); 
    } 

    cursor.close(); 
    cursor = null; 

    return contactName; 
} 

它工作得很好,但getContactName()有一个错误:

The method getContentResolver() is undefined for the type SMSReceiver 

可能是什么问题呢?任何帮助真的很感激。

我想问题可能是BroadcastReceiver不能从Context继承。当您获取contentresolver时,您需要使用传递给onReceive()的Context。因此,在getContactName()方法,而不是这样的:

Cursor cursor = this.getContentResolver().query(uri, projection, null, null, null); 

你应该使用这样的:

Cursor cursor = context.getContentResolver().query(uri, projection, null, null, null);
