好吧，所以我正在尝试从Weather Underground的一个JSON文件输出一些Android应用程序的数据。我需要的是当前的温度和当天的条件，接下来的10天。提供的JSON数据给出了10天的展望，但我不知道如何分别解析每一天。而且，我甚至无法将温度和条件变为单个字符串输出。
这是JSON集：

到目前为止，这是我的代码（第一天片段）
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");
}
}
}
我认为获得每天预测的最佳方法可能是在JSON集上运行一个循环，然后打印出与每天相对应的“句号”。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。
如果有人能帮助我弄清楚如何至少获得当天的预测，我会很高兴。但如果我能以任何其他方式开悟，请告诉我。感谢。

我看到错误，你试图获取JsonArray而不是JsonObject，以验证你可以使用下一页来查看你的json http://www.jsoneditoronline.org/
您更改了代码。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);
Log.v(TAG, "-Con-" + 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");
}
}
