使用1次的BroadcastReceiver

Question

晚上好，我有一個簡單的程序，當我接到電話時，它會激活BroadcastReceiver來檢測電話號碼，問題是當我接到電話時，它將再次寫入數據庫，而當我再次斷開呼叫記錄時，將寫入總和3次！ 而且我只想在玩的時候1！ 另一個問題是電話響起時，在數據庫中寫入徽標（這里可以！），但是它不接聽電話，而是再次寫入電話！ 代碼是這樣的：

我的廣播：它的作品！

public class MyBroadcastReceiver extends BroadcastReceiver {    
    String idtelemovel="1";
    String phone_number;
    @Override
    public void onReceive(Context context, Intent intent) {
        System.out.println("Entrou no BroadCastReceiver!!! : ");
        Bundle bundle = intent.getExtras();
        phone_number = bundle.getString("incoming_number");
        System.out.println("Phone Number : " + phone_number);
        Log.i("zz", "Phone Number : " + phone_number);
        new SummaryAsyncTask().execute((Void) null); 
    }
    class SummaryAsyncTask extends AsyncTask<Void, Void, Boolean> {    
        private void postData(String phone_number) {
         HttpClient httpclient = new DefaultHttpClient();
         HttpPost httppost = new HttpPost("http://www.AAA.com/insert.php");     
            try {
                ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(4);
                nameValuePairs.add(new BasicNameValuePair("Street", phone_number));
                nameValuePairs.add(new BasicNameValuePair("House", idtelemovel));

                httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
                HttpResponse response = httpclient.execute(httppost);
                }
            catch(Exception e)
                {
                    Log.e("log_tag", "Error:  "+e.toString());
                    System.out.print("*********fail*********");
                }
        }
        @Override
        protected Boolean doInBackground(Void... params) {
        postData(phone_number);
        return null;
        }
    }
    }

廣播意圖還包括呼叫狀態（空閑，響鈴，摘機）。 您可以使用Telephony.EXTRA_STATE鍵讀取它，然后將其與可能的值進行比較。 例如：

String state = intent.getStringExtra(TelephonyManager.EXTRA_STATE);
if (TelephonyManager.EXTRA_STATE_RINGING.equals(state))
{
    String phoneNumber = intent.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER);
    // call your asynctask ...
}
