I want to create file in which the first line will be constantly updated.我想创建第一行将不断更新的文件。 actually I want to save this file to custom path, for example /storage/emulated/0/Download, but I don't know how to do that, so now I have something like this:
实际上我想将这个文件保存到自定义路径,例如/storage/emulated/0/Download,但我不知道该怎么做,所以现在我有这样的东西:
public void save(){
while(true) {
try {
String FILENAME = "my_file";
String string = "" + System.currentTimeMillis();
FileOutputStream fos = openFileOutput(FILENAME, MODE_PRIVATE);
fos.write(string.getBytes());
} catch (Exception e) {
e.printStackTrace();
}
}
}
and this code gives me two errors这段代码给了我两个错误
FileOutputStream fos = getApplicationContext().getContextResolver().openFileOutput(FILENAME);
Before using openFileOutpout()
you have to use getContextResolver()
and there is no Context.MODE_PRIVATE
parameter in this function在使用
openFileOutpout()
之前,您必须使用getContextResolver()
并且此 function 中没有Context.MODE_PRIVATE
参数
