仅使用扫描仪读取应用程序中的txt文件

Question

I need to read file that stays in my app, and I want to use Scanner , but I have a problem when I put it in assets or res .

This is my part of code

import java.util.Scanner;

public class Zapis {
    public void zapis() {
        // TODO Auto-generated method stub

        Scanner scanner = new Scanner("assets/glvanii_ekran/glavnii_ekran.txt");
        while (scanner.hasNextLine() == true){
            MainActivity.list.add(scanner.nextLine());
        }
        scanner.close();
    }

}

Answer 1

Open your asset using an InputStream and then wrap it with a Scanner, as follows:

InputStream myFile = getResources().getAssets().open("file:///android_asset/glvanii_ekran/glavnii_ekran.txt");
Scanner scanner = new Scanner(myFile);
