实例如下所示：
public class MainActivity {
private static final String fileName = "D:/Tao/MyEclipseWorkspace/resources/weather.txt";
public static void main(String[] args) {
//读取文件
BufferedReader br = null;
StringBuffer sb = null;
try {
br = new BufferedReader(new InputStreamReader(new FileInputStream(fileName),"GBK")); //这里可以控制编码
sb = new StringBuffer();
String line = null;
while((line = br.readLine()) != null) {
sb.append(line);
}
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
br.close();
} catch (Exception e) {
e.printStackTrace();
}
}
String data = new String(sb); //StringBuffer ==> String
System.out.println("数据为==> " + data);
}
}
