Android：从MySQL到TextView的Emojis

Question

我有一个带有Utf8_mb4_general_ci的数据库和我的表情符号。 （的 \ ud83d \ ude3b ） iOS有效。但是，如果我将在TextView(Android)中显示此unicode。它不起作用。你能救我吗？

这是我的JSON：

[{"user_bewerten":"","anz_com":"7","rating":"0","id":"291","titel":"\\ud83d\\ude3b","text":"\\ud83d\\ude3b","cityId":"2","city_name":"Aachen","userId":"1359280c82c7c0804c5ad3235153346dc2bdde45c7150cda88ae59f2e206d61b","created_at":"2016-06-20 10:58:02"}]

这是我的功能：

Context context = this.curContext.getApplicationContext();
        CheckInternetConnectionChangeReceiver cm = new CheckInternetConnectionChangeReceiver();
        if(cm.CheckInternetConnection(context))
        {
            boolean bErg = connectSchnacken(url);

            if(bErg==true)
            {
                Log.d("2","2");
                try {
                    Log.d("2","2");
                    dataJSON = json;
                    Log.d("dataJSON: ",dataJSON.toString());
                    if(dataJSON.length() > 0){
                        bLeer = false;
                        for(int i = 0; i < dataJSON.length(); i++){
                            Log.d("id: "+i, ""+i);
                            JSONObject c = dataJSON.getJSONObject(i);

                            classSchnacken thisContent = new classSchnacken();
                                thisContent.setId(c.getInt("id"));
                                String id = ""+c.getInt("id");
                                Log.d("id: "+i, ""+c.getInt("id"));
                                thisContent.setTitle(c.getString("titel"));
                                Log.d("Titel: "+i, c.getString("titel"));
                                thisContent.setText(c.getString("text"));
                                Log.d("Text: "+i, c.getString("text"));
                                thisContent.setUser(c.getString("userId"));
                                Log.d("userId: "+i, c.getString("userId"));
                                thisContent.setTime(c.getString("created_at"));
                                Log.d("Time: "+i, c.getString("created_at"));
                                thisContent.setCityName(c.getString("city_name"));
                                thisContent.setAnzKommentare(c.getString("anz_com"));
                                thisContent.setAnzBewertungen(c.getString("rating"));

                                String currentMail = getEmailAccount();
                                if(c.getString("user_bewerten").toLowerCase().contains(currentMail.toLowerCase())==true)
                                {
                                    thisContent.setBewertungsStatus("1");
                                }
                                else
                                {
                                    thisContent.setBewertungsStatus("0");
                                }
                                Log.d("user_bewerten: "+i, c.getString("user_bewerten"));
                                Log.d("user_bewerten: "+i, thisContent.getBewertungsStatus());
                            // ADD
                            dataListTemp.add(thisContent);

                        }
                    }
                    else
                    {
                        bLeer = true;
                        Log.d("leer", "leer");
                    }
                } catch (JSONException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                    Log.d("Fehler: ", e.toString());
                }
            }
        }
    }

    dataListSchnacken = (ArrayList<classSchnacken>) dataListTemp;

    return dataListTemp;
  }

PHP：

  $query_exec = mysql_query($query_search) or die(mysql_error());
  if (mysql_errno())
  {
     header("HTTP/1.1 500 Internal Server Error");
     echo $query.'\n';
     echo mysql_error();
  }
  else
  {
     if( $query_exec!=null)
     {
        while($row=mysql_fetch_assoc($query_exec))
            print(json_encode($output));
     }
     else {echo "No Data"; }
     mysql_close(); 
   }

$ query_search是我的SQL查询。
