Android reads from a file… here is a solution to the problem.
Android reads from a file
I’m new to android and can’t understand the reason for the new assignment in the loop while reading a book. Isn’t it enough to do it once before looping?
FileInputStream fIn =
openFileInput("textfile.txt");
InputStreamReader isr = new
InputStreamReader(fIn);
char[] inputBuffer = new char[READ_BLOCK_SIZE];
String s = "";
int charRead;
while ((charRead = isr.read(inputBuffer))>0)
{
---convert the chars to a String---
String readString =
String.copyValueOf(inputBuffer, 0,
charRead);
s += readString;
inputBuffer = new char[READ_BLOCK_SIZE];
}
Solution
From String.copyValueOf
javadoc :
/**
* Creates a new string containing the specified characters in the character
* array. Modifying the character array after creating the string has no
* effect on the string.
*
* @param start
* the starting offset in the character array.
* @param length
* the number of characters to use.
So there’s no reason to create a new char[] in the loop.
