将JSON数据解析为Java for Android Weather App
[英]Parsing JSON data to Java for Android Weather App
问题描述
好吧，所以我试图为Android应用从Weather Underground的JSON文件中输出一些数据。 我需要的是未来10天当前的温度和状况。 提供的JSON数据提供了10天的前景，但是我不知道如何分别解析每天。 而且，我什至在尝试仅将温度和条件转换为单个字符串输出时遇到麻烦。
这是JSON集：

这是到目前为止的代码（第一天的片段）
class RequestCurrentMplsWeatherTask extends AsyncTask<String, String, String>{ @Override protected String doInBackground(String... uri) { String responseString = null; try { HttpClient client = new DefaultHttpClient(); URI apiCall = new URI("http://api.wunderground.com/api/MYID/forecast10day/q/MN/Minneapolis.json"); HttpGet request = new HttpGet(); request.setURI(apiCall); HttpResponse response = client.execute(request); responseString = EntityUtils.toString(response.getEntity()); } catch (Exception e) { Log.e(TAG, "some sort of problem encountered", e); } return responseString; } @Override protected void onPostExecute(String result) { super.onPostExecute(result); if (result != null ){ Log.i(TAG, "result data was \\n" + result); try { JSONObject jsonWeather = new JSONObject(result); JSONObject weatherForecast = jsonWeather.getJSONObject("forecast"); JSONObject simpleForecast = weatherForecast.getJSONObject("simpleforecast"); JSONArray forecastArray = simpleForecast.getJSONArray("forecastday"); for (int i = 0; i < forecastArray.length(); i++) { JSONObject fa = forecastArray.getJSONObject(i); JSONArray highArray = fa.getJSONArray("high"); for (int h = 0; h < highArray.length(); h++) { JSONObject ha = highArray.getJSONObject(h); JSONObject fahrenheit = ha.getJSONObject("fahrenheit"); TextView output1 = (TextView)findViewById(R.id.today_temp); output1.setText("" + fahrenheit); break; } JSONObject conditions = fa.getJSONObject("conditions"); //JSONObject conditionsArray = fa.getJSONObject("conditions"); TextView output2 = (TextView)findViewById(R.id.fctext); output2.setText("" + conditions); break; } //String forecastArrayResult = weatherForecast.getString("temp_f"); } catch (JSONException jse) { Log.e(TAG, "Error parsing JSON", jse); return; } } else { Log.i(TAG, "String returned was Null, check doInBackground for errors"); } } }
我认为获得每日天气预报的最好方法是在JSON集上运行循环，然后在与每天相对应的“期间”上打印。 但是，我无法弄清楚如何将上述温度和预测数据打印到带有JSON的for循环设置的参数中。
如果有人可以帮助我至少弄清楚如何获得当日天气预报，我将很高兴。 但是，如果我可以通过其他任何方式得到启发，请告诉我。 谢谢。

我看到错误，您尝试获取JsonArray而不是JsonObject，以验证您可以使用下一页查看json http://www.jsoneditoronline.org/
您更改代码。 这是我的代码。
@Override
protected void onPostExecute(String result) {
super.onPostExecute(result);
if (result != null) {
Log.i(TAG, "result data was \n" + result);
try {
JSONObject jsonWeather = new JSONObject(result);
JSONObject weatherForecast = jsonWeather
.getJSONObject("forecast");
JSONObject simpleForecast = weatherForecast
.getJSONObject("simpleforecast");
JSONArray forecastArray = simpleForecast
.getJSONArray("forecastday");
for (int i = 0; i < forecastArray.length(); i++) {
JSONObject fa = forecastArray.getJSONObject(i);
JSONObject highArray = fa.getJSONObject("high");
//for (int h = 0; h < highArray.length(); h++) {
String fahrenheit = highArray.getString("fahrenheit");
//JSONObject fahrenheit = ha.getJSONObject("fahrenheit");
Log.v(TAG, "-fa-" + fahrenheit);
//break;
//}
String conditions = fa.getString("conditions");
// JSONObject conditionsArray =
// fa.getJSONObject("conditions");
// TextView output2 = (TextView)findViewById(R.id.fctext);
// output2.setText("" + conditions);
