Android 中文字符转UTF-8编码

 import java.io.UnsupportedEncodingException;
 import java.net.URLDecoder;
 import java.net.URLEncoder;


 public class Test {
     public static void main(String[] args) {
         String str = "测试字符转换 hello word"; //默认环境，已是UTF-8编码
         try {
             String strGBK = URLEncoder.encode(str, "GBK");
             System.out.println(strGBK);
             String strUTF8 = URLDecoder.decode(str, "UTF-8");
             System.out.println(strUTF8);
         } catch (UnsupportedEncodingException e) {
             e.printStackTrace();
         }
     }
 }

今天Android工程中涉及到字符转换，二维码中文需要转换为UTF-8,否则搜索出来会出现乱码
