复制代码 代码如下:

// 读取sdcard文件

private void sdcardRead(){

String fileName = "/sdcard/my_sdcard.txt";// assets下文件

//String fileName = "/sdcard/test/my_sdcard_test.txt";// sdcard下子目录文件

String ret = "";

try {

FileInputStream fis = new FileInputStream(fileName);

int len = fis.available();

byte []buffer = new byte[len];

fis.read(buffer);

ret = EncodingUtils.getString(buffer, "UTF-8");

fis.close();

} catch (Exception e) {

e.printStackTrace();

}

tvTXT.setText(ret);

}
