1.内置Json

  

private String json0 = "{\"name\":\"hello json\"}";    private String jsonArray1 = "{\"query\":\"Pizza\",\"locations\":[94043,90210]}";    private String jsonArray2 = "{\"number\":[[zhangsan,133],[lisi,3234]]}";    private String jsonArray3 = "{\"mobile\":[{\"name\":\"android\"},{\"name\":\"iphone\"}]}";  try {            JSONObject demoJson = new JSONObject(json0);            String name = (String) demoJson.get("name");            Log.i("name-->value：", name);            JSONObject demoJson1 = new JSONObject(jsonArray1);            String query = demoJson1.getString("query");            Log.i("query-->value:", query);            JSONArray locationArray = demoJson1.getJSONArray("locations");            for (int i = 0; i < locationArray.length(); i++) {                Log.i("location-->value：", String.valueOf(locationArray.getInt(i)));            }            JSONObject demoJson2 = new JSONObject(jsonArray2);            JSONArray array = demoJson2.getJSONArray("number");            for (int i = 0; i < array.length(); i++) {                JSONArray tmp = array.getJSONArray(i);                Log.i("嵌套数组-->value:", tmp.getString(0) + tmp.getInt(1));            }            JSONObject demoJson3 = new JSONObject(jsonArray3);            JSONArray array1 = demoJson3.getJSONArray("mobile");            for(int i =0;i
     
      value:",innername);            }
