public static String getContactName(Context context, String id, String address){

        if(id==null){
            if(address==null){
                return null;
            }else{
                return PhoneNumberUtils.formatNumber(address);
            }
        }

        Cursor cursor = context.getContentResolver().query(
                ContactsContract.Data.CONTENT_URI, 
                null, 
                null, 
                null, 
                null);

        if(cursor!=null){
            try{
                if(cursor.moveToFirst()){
                    do{
                        for(int i=0;i<cursor.getColumnCount();++i){
                            String columnName = cursor.getColumnName(i);
                            String columnText = cursor.getString(i);
                            Log.d(columnName, columnText==null ? "null":columnText);
                        }
                        Log.d("endline","***************************");
                    }while(cursor.moveToNext());


                }else{
                    Log.d("cursor", "not greater than 0");
                }
            }finally{
                cursor.close();
            }
        }

        if(address != null){
            return PhoneNumberUtils.formatNumber(address);
        }

        return "just testing shit";
    }

所以我的问题是，当我退回所有联系人时，我会得到每个联系人的多个副本，我不知道为什么，或者该怎么做。我在网上查看了我的联系人：https://www.google.com/contacts/#contacts

除了删除手机中的所有联系人并重新加入谷歌联系人以确保没有重复。我无法理解发生了什么，虽然我可能只是在某种程度上是愚蠢的。

以下是输出的内容（截断为几个联系人）

我是个白痴。在我提出这个问题后，我几乎立即找到了问题的答案。

请参阅：https://stackoverflow.com/a/3591323/2408279

基本上，每种联系类型都有一个参考I.E.电子邮件，电话等（如果我没记错的话）

您应该查询public class DownloadTask { private static final String TAG = "Download Task"; private Context context; private Button buttonText; private String downloadUrl = "", downloadFileName = ""; public DownloadTask(Context context, String downloadUrl) { this.context = context; this.buttonText = buttonText; this.downloadUrl = downloadUrl; downloadFileName = downloadUrl.replace("", "");//Create file name by picking download file name from URL Log.e(TAG, downloadFileName); //Start Downloading Task new DownloadingTask().execute(); } private class DownloadingTask extends AsyncTask<Void, Void, Void> { File apkStorage = null; File outputFile = null; @Override protected void onPreExecute() { super.onPreExecute(); } @Override protected void onPostExecute(Void result) { try { if (outputFile != null) { buttonText.setEnabled(true); Log.e("57","download"+"completed"); } else { new Handler().postDelayed(new Runnable() { @Override public void run() { Log.e("62","download again"); } }, 3000); Log.e(TAG, "Download Failed"); } } catch (Exception e) { e.printStackTrace(); Log.e("72,","download failed"); //Change button text if exception occurs new Handler().postDelayed(new Runnable() { @Override public void run() { Log.e("80","download again"); } }, 3000); Log.e(TAG, "Download Failed with Exception - " + e.getLocalizedMessage()); } super.onPostExecute(result); } @Override protected Void doInBackground(Void... arg0) { try { URL url = new URL(downloadUrl);//Create Download URl HttpURLConnection c = (HttpURLConnection) url.openConnection();//Open Url Connection c.setRequestMethod("GET");//Set Request Method to "GET" since we are grtting data c.connect();//connect the URL Connection //If Connection response is not OK then show Logs if (c.getResponseCode() != HttpURLConnection.HTTP_OK) { Log.e(TAG, "Server returned HTTP " + c.getResponseCode() + " " + c.getResponseMessage()); } //Get File if SD card is present if (new CheckForSDCard().isSDCardPresent()) { apkStorage = new File(Environment.getExternalStorageDirectory() + "/" + "downloadDirectory"); } else Toast.makeText(context, "Oops!! There is no SD Card.", Toast.LENGTH_SHORT).show(); //If File is not present create directory if (!apkStorage.exists()) { apkStorage.mkdir(); Log.e(TAG, "Directory Created."); } outputFile = new File(apkStorage, downloadFileName);//Create Output file in Main File //Create New File if not present if (!outputFile.exists()) { outputFile.createNewFile(); Log.e(TAG, "File Created"); } FileOutputStream fos = new FileOutputStream(outputFile);//Get OutputStream for NewFile Location InputStream is = c.getInputStream();//Get InputStream for connection byte[] buffer = new byte[1024];//Set buffer type int len1 = 0;//init length while ((len1 = is.read(buffer)) != -1) { fos.write(buffer, 0, len1);//Write new file } //Close all connection after doing task fos.close(); is.close(); } catch (Exception e) { //Read exception if something went wrong e.printStackTrace(); outputFile = null; Log.e(TAG, "Download Error Exception " + e.getMessage()); } return null; } } } ，ContactsContract.CommonDataKinds.Phone表格，让我知道它是否有帮助。

正如pskink所说，使用CONTENT_URI来记录光标..更简单
