android 读取SD卡下TXT文件

直接上代码了

File f=null;
f= new File("/sdcard/cet4hard.txt");//这是对应文件名
InputStream in = null;
try {
in = new BufferedInputStream(new FileInputStream(f));
} catch (FileNotFoundException e3) {
// TODO Auto-generated catch block
e3.printStackTrace();
}
BufferedReader br = null;
try {
br = new BufferedReader(new InputStreamReader(in, "gb2312"));
} catch (UnsupportedEncodingException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
String tmp;

try {
while((tmp=br.readLine())!=null){
//在这对tmp操作
}
br.close();
in.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();

}





这跟之前读取raw下的TXT文件有点不一样，就是开始两行代码...直接用应该没问题
