Java 如何从json数组中获取内部数组值,java,android,json,Java,Android,Json,这是json响应： [ { "currentvalue": [ { "id": "13", "current_value": "0,1", "create_date": "2015-06-15 06:12:14", "status": "0", "modify_date": "0000-00

如何从“目标”数组中获取指示符名称值：

您可以这样尝试。

对于（int i=0；i您可以这样做


for(int i=0; i<jsonArray.length(); i++)
{
    JSONObject object = jsonArray.getJSONObject(i);
    JSONObject target = object.getJSONObject("target");
    String indicator_name = target.getString("indicator_name");
}



try {
                    JSONArray _jArrayMain = new JSONArray("YOURJSONSTRING");
                    for (int i = 0; i < _jArrayMain .length(); i++) {
                        JSONObject _jObj = _jArrayMain.getJSONObject(i);
                        JSONObject   _jObjTarget = _jObj.getJSONObject("target");
                        String _indicator_name = _jObjTarget.getString("indicator_name");
                        System.out.println("Indicator Name : " + _indicator_name);
                    }
                } catch (JSONException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }



试试看{
JSONArray _jArrayMain=新的JSONArray（“YOURJSONSTRING”）；
对于（int i=0；i<_jArrayMain.length（）；i++）{
JSONObject jObj=jArrayMain.getJSONObject（i）；
JSONObject_jObjTarget=_jObj.getJSONObject（“目标”）；
String _indicator_name=_jObjTarget.getString（“indicator_name”）；
System.out.println（“指标名称：”+_指标名称）；
}
}捕获（JSONException e）{
//TODO自动生成的捕捉块
e、 printStackTrace（）；
}

您可以使用下面的代码段


final JSONArray jsonArray = new JSONArray("JSON_STRING");
for (JSONObject jObject: jsoonArray) {
     final JSONObject   jsonTargetObject = jObject.optJSONObject("target");
     if(jsonTargetObject != NULL) {
     final String indicatorName = jsonTargetObject.optString("indicator_name", null);
     System.out.println("Indicator Name : " + indicatorName);
}
