android: getResources().getIdentifier NotFound 异常

Question

我通过 json 获取我的数据。将其放入 Hashmap 并在 ListView 中列出。效果很好!

现在我想要这样的东西:

String myArt=report_TJ_+e.getString("artID");

这在我的组合中不起作用。这是我的代码:

  try{
    //String text = getString(R.string.report_TJ);
    JSONArray  earthquakes = json.getJSONArray("uTraf");
    mylist.clear();
    String report_TJ_btn = null;
            for(int i=0;i<earthquakes.length();i++){                        
                HashMap<String, String> map = new HashMap<String, String>();    
                JSONObject e = earthquakes.getJSONObject(i);

                String imageString=report_TJ_btn+e.getString("artID");
                String myArt = getString(getResources().getIdentifier(imageString, "", getPackageName()));

                map.put("id",  String.valueOf(i));
                map.put("first", myArt + "Stau: " + e.getString("road") + ", " + e.getString("county"));
                map.put("second", e.getString("timestamp") + ", " + e.getString("suburb"));
                mylist.add(map);
            }       
  }

错误:E/AndroidRuntime(641): Caused by: android.content.res.Resources$NotFoundException: 字符串资源 ID #0x0

您必须将 "string" 而不是 "strings" 设置为第二个参数。

String myArt = getString(getResources().getIdentifier(imageString, "string", getPackageName()));
