The example described in this article is the code for the analysis of weather data for the Android weather forecast, which enables the acquisition of HttpGet objects to read weather data, and to parse weather data from the data, such as temperature, temperature, wind power, wind direction, weather trends for the next few days, weather conditions, air pollution indices, Also included is the call to the corresponding picture or weather animation file, for the development of the Android weather program can refer to the example of this article.

The specific function code is as follows:
