Android 保存字符串
我正在尝试将 url 保存为字符串,以便我可以在应用程序的其他部分使用它,但它无法正常工作。这就是我所拥有的。
保存
String FILENAME = "usertimetable";
String string = mWebView.getOriginalUrl();
FileOutputStream fos = null;
try {
fos = openFileOutput(FILENAME, Context.MODE_PRIVATE);
fos.write(string.getBytes());
fos.close();
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
开局
FileInputStream fis = null;
try {
fis = openFileInput("usertimetable");
url = fis.toString();
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
I'm trying to save a url as a string so that I can use it in another part of my app but its not working properly. Here's what I have.
Saving
String FILENAME = "usertimetable";
String string = mWebView.getOriginalUrl();
FileOutputStream fos = null;
try {
fos = openFileOutput(FILENAME, Context.MODE_PRIVATE);
fos.write(string.getBytes());
fos.close();
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Opening
FileInputStream fis = null;
try {
fis = openFileInput("usertimetable");
url = fis.toString();
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

尝试使用
read()
方法,而不是toString()
。(http://developer.android.com/reference/java/io/FileInputStream. html 了解更多信息。)
Try using the
read()
method, rather thantoString()
.(http://developer.android.com/reference/java/io/FileInputStream.html for more info.)
