我正在製作一個應用程序,用於監聽所有傳入的SMS消息並將其安全地發送到我的服務器上的數據庫。我還想發送所有傳入的SMS消息的顯示名稱,完成此操作的最佳方法是什麼?是否有一種方法我可以用傳入的消息來做到這一點,或者是實現這一目標的唯一方法是創建一個函數,該函數將搜索我的聯繫人與smsMessage [0] .getOriginatingAddress()相同的號碼, 。這裏是我的功能,我發現和我進來的消息代碼:如何僅通過電話號碼獲取聯繫人姓名?

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()有一個錯誤:

The method getContentResolver() is undefined for the type SMSReceiver 

可能是什麼問題呢?任何幫助真的很感激。

我想問題可能是BroadcastReceiver不能從Context繼承。當您獲取contentresolver時,您需要使用傳遞給onReceive()的Context。因此,在getContactName()方法,而不是這樣的:

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

你應該使用這樣的:

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