                //get current JSONObject from result JSONObject
                JSONObject currentJSONObject = jsonObject.getJSONObject("current");

                //Now get condition JSONObject from current JSONObject
                JSONObject conditionJSONObject = currentJSONObject.getJSONObject("condition");
                text = conditionJSONObject.getString("text");

                //Now print condition JSONObject
                Log.i("website content", "condition json object : " + text.toString());
                JSONArray arr= new JSONArray(conditionJSONObject.toString());


            } catch (Exception e){

            }

        }
    }

public  void click(View view){

    resultofw.setText(text);
    


}


}
＆＃13;
＆＃13;
＆＃13;

那我怎么能解决这个问题呢，我试着把字符串添加到数组中。然后在＆＃34; text＆＃34;

之后拉出所说的内容

＆＃13;
＆＃13; 
//conver result into json object
            try{
                JSONObject jsonObject=new JSONObject(result);

                //get current JSONObject from result JSONObject
                JSONObject currentJSONObject = jsonObject.getJSONObject("current");

                //Now get condition JSONObject from current JSONObject
                JSONObject conditionJSONObject = currentJSONObject.getJSONObject("condition");

                //Now print condition JSONObject
                Log.i("website content", "condition json object : " + conditionJSONObject.toString());
                JSONArray arr= new JSONArray(conditionJSONObject.toString());

                for(int i=0;i<arr.length();i++){
                    JSONObject jsonpart= arr.getJSONObject(i);
                    Log.i("Part",jsonpart.getString("text"));
                }
＆＃13;
＆＃13;
＆＃13;

实际上，condition是JSONObject所以你需要从结果JSONObject解析它，如下所示。

    @Override
    protected void onPostExecute(String result) {
        super.onPostExecute(result);
        //conver result into json object
        try{
            JSONObject jsonObject=new JSONObject(result);

            //get current JSONObject from result JSONObject
            JSONObject currentJSONObject = jsonObject.getJSONObject("current");

            //Now get condition JSONObject from current JSONObject
            JSONObject conditionJSONObject = currentJSONObject.getJSONObject("condition");

            //Now print condition JSONObject
            Log.i("website content", "condition json object : " + conditionJSONObject.toString());

        } catch (Exception e){

        }

    }

只需在getString上调用conditionJSONObject方法即可获得＆＃34; text＆＃34;的值如下所示

String text = conditionJSONObject.getString("text");

Log.d（＆＃34;网站内容＆＃34;，jsonObject.getString（＆＃34;条件＆＃34;）。toString（））;
