Android中文天氣預(yù)報(bào)程序

1、http:Android中文天氣預(yù)報(bào)程序2010年09月13日星期一12:47大家好！由于項(xiàng)目原因好長時(shí)間沒學(xué)android了。今天抽出點(diǎn)兒時(shí)間做個(gè)天氣預(yù)報(bào)程序。貼出來希望對(duì)大家有用。先說一下Google天氣預(yù)報(bào)的AIP吧。http:我發(fā)現(xiàn)在模擬器上面返回的結(jié)果和在pc上返回的結(jié)果不太一樣，pc上有中文的，android模擬器上沒有的。好了不說別的了。開始吧！nowstart。1。建立工程。我取名sbsWeather。結(jié)構(gòu)如下:日上hsbsWeather-com,weatherCntoEn.java+1Ut依Java+：IWeatherjava國西genGeneratedJavaFiles+a

6、文。一對(duì)一的轉(zhuǎn)換吧，好像沒別的跟好的辦法。另外其中還有個(gè)方法是將網(wǎng)絡(luò)圖片轉(zhuǎn)換為android的bitmap對(duì)象的。1.2. packagecom.sbs.weather;3. importjava.io.IOException;4. importjava.io.InputStream;5. .HttpURLConnection;6. .MalformedURLException;7. .URL;8. importandroid.graphics.Bitmap;9. importandroid.graphics.BitmapFactory;10. publicclassUtils11. publ
