francisnnumbi / InnerReader.java

Created July 13, 2017 06:05

Simple class that reads res/raw text file using Scanner.class It has got one static method that require the Context and the resource id of the file to be read. It is a simple demonstration of reusability. The other way is to use a succession of InputStream - InputStreamReader - BufferedReader to read that res/raw text file.

	import android.content.res.*;
	import java.util.*;
	import android.content.*;

	public class InnerReader
	{

	public static String readText(Context context, int resId){
	StringBuilder sb = new StringBuilder();
	Scanner reader = new Scanner(context.getResources().openRawResource(resId));

i need your advice. this is the class i use for highlighting my text in my EditText. It works fine, well to some extents! But when the text starts growing in size, it starts freezing! I know, this is due to multiple while...loops. My concern is the way of changing so that i have at least one loop.
