问题在于,当我使用此代码阅读它时,我似乎无法返回文本文件中的确切内容。
File f = new File("fprint.txt");
RandomAccessFile randomFile = new RandomAccessFile(f, "rw");
String fromFile = randomFile.readLine();
当我记录“fromFile”时,我得到了

这比我输入的更短。我希望能够以完全相同的方式读取文件中的所有内容。谢谢
已编辑:日志代码
Log.i("Check File", "Content of File: " + fromFile );
答案 0 :(得分:1)
您应该使用read()
方法,而不是readLine()
,例如:
public static String getBase64FromFile(String path) throws IOException {
RandomAccessFile file = new RandomAccessFile(path, "r");
String result = "";
int b = file.read();
while (b != -1) {
result = result + (char) b;
b = file.read();
}
file.close();
return result;
}
