Android [project] Android Weather Forecast

This project is based on WebService and uses ksoap2 to parse WebServices on the network.

In fact, there are not many technical difficulties. Let's look at the source code and explain it again.

There are three methods to parse the province, city, and weather data respectively. WebService is used for data interaction.

This weather is suitable for traveling, so you can enjoy the scenery of nature. Road Condition Index: Cloudy, the road surface is dry, and the road condition is good. Comfort index: the temperature is suitable, and the wind power is not great. In such weather conditions, you will feel fresh and comfortable. // Air Pollution Index: meteorological conditions are conducive to air pollutant dilution, diffusion, and removal, and can be normally performed outdoors.

This is just a summary of some data, mainly to help readers learn how to use the ksoap2 class. The comments in the Code are also clearly written. in fact, if you want to make good applications, you should learn how to use network resources to interact with your own applications. After all, network resources are infinite, such as XML parsing, you can also parse the XML file of the Group Buying website.
