保存文本文件的位置，以便能够将其读入Android项目

Question

I have looked around to find out where to save general text files for reading into my Android project, but couldn't find a definite answer. When I save my "foo.txt" file into my res/raw folder as someone suggested (I had to create the raw folder) the R.java file gets error for these lines:

public static final class raw {
    public static final int 1_1=0x7f050000;
}

This is because my file contains the string "1_1" on the first line, which I want it to have. Where in the folder structure should I put my file to be able to read it? The file is not created from Android but manually by me.

Could someone also please advise on how to read a file in the following format? I want to be able to read the Strings and numbers one by one and insert into java variables in my Android project. Is it best to separate with commas or spaces?

1_1
String
Int
Int String String Int Int Float Float Int Int
Int String String Int Int Float Float Int Int
Int String String Int Int Float Float Int Int
Int String String Int Int Float Float Int Int
Int String String Int Int Float Float Int Int
Int String String Int Int Float Float Int Int

Updated with more code:

package com.my.package;

import java.io.File;

import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.ImageButton;
import android.widget.TextView;
import android.widget.Toast;

//public class GameActivity extends FragmentActivity implements OnClickListener {
public class GameActivity extends Activity implements OnClickListener{  

private ImageButton leftPauseButton;
private ImageButton rightPauseButton;

private ImageButton leftButton1;
private ImageButton leftButton2;
private ImageButton leftButton3;

private ImageButton rightButton1;
private ImageButton rightButton2;
private ImageButton rightButton3;


  public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.testlayout);
        TextView txtView = (TextView) (findViewById(R.id.testID_canBeRemoved));

            //Did not work
        //int resourceId = this.getResources().getIdentifier("com.my.package:raw/foo.txt", null, null);
        //File f = new File("com.my.package:raw/foo.txt");

            //Does not work - file.exists() returns a zero value
        File file = new File("assets/foo.txt");

        if ( file.exists() ){
            txtView.setText("Exists");
        }
        else{
            txtView.setText("Does not exist");
        }


//          InitiateUIComponents();

    }

        //This is for using another xml layout
    private void InitiateUIComponents(){

        leftPauseButton = (ImageButton) (findViewById(R.id.leftPauseButtonID));
        rightPauseButton = (ImageButton) (findViewById(R.id.rightPauseButtonID));

        leftButton1 = (ImageButton) (findViewById(R.id.leftMenuButton1ID));
        leftButton2 = (ImageButton) (findViewById(R.id.leftMenuButton2ID));
        leftButton3 = (ImageButton) (findViewById(R.id.leftMenuButton3ID));

        rightButton1 = (ImageButton) (findViewById(R.id.rightMenuButton1ID));
        rightButton2 = (ImageButton) (findViewById(R.id.rightMenuButton2ID));
        rightButton3 = (ImageButton) (findViewById(R.id.rightMenuButton3ID));

        leftPauseButton.setOnClickListener(this);
        rightPauseButton.setOnClickListener(this);

        leftButton1.setOnClickListener(this);
        leftButton2.setOnClickListener(this);
        leftButton3.setOnClickListener(this);

        rightButton1.setOnClickListener(this);
        rightButton2.setOnClickListener(this);
        rightButton3.setOnClickListener(this);

    }

            //This is for using another xml layout
    @Override
    public void onClick(View v) {

        switch (v.getId()) {
        case R.id.leftPauseButtonID:
            Toast.makeText(this, "Left pause button clicked!", Toast.LENGTH_SHORT).show();
            break;
        case R.id.rightPauseButtonID:
            Toast.makeText(this, "Right pause button clicked!", Toast.LENGTH_SHORT).show();
            break;
        case R.id.leftMenuButton1ID:
            Toast.makeText(this, "Left menu button 1 clicked!", Toast.LENGTH_SHORT).show();
            break;
        case R.id.leftMenuButton2ID:
            Toast.makeText(this, "Left menu button 2 clicked!", Toast.LENGTH_SHORT).show();
            break;
        case R.id.leftMenuButton3ID:
            Toast.makeText(this, "Left menu button 3 clicked!", Toast.LENGTH_SHORT).show();
            break;
        case R.id.rightMenuButton1ID:
            Toast.makeText(this, "Right menu button 1 clicked!", Toast.LENGTH_SHORT).show();
            break;
        case R.id.rightMenuButton2ID:
            Toast.makeText(this, "Right menu button 2 clicked!", Toast.LENGTH_SHORT).show();
            break;
        case R.id.rightMenuButton3ID:
            Toast.makeText(this, "Right menu button 3 clicked!", Toast.LENGTH_SHORT).show();
            break;


        default:
            break;
        }

    }

}

And here is the xml file for this test:

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>

<TextView 
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:id="@+id/testID_canBeRemoved"
    android:text="Blabla"
>

</TextView>
</LinearLayout>

Answer 1

First : 1_1 is not a valid variable name. As per the Java Documentation:

A variable's name can be any legal identifier — an unlimited-length sequence of Unicode letters and digits, beginning with a letter, the dollar sign "$", or the underscore character "_".

Second : The file should be saved in the assets folder.

Third : To read the file, you can use a Scanner . If your String s don't have spaces in them, this would work:

Scanner in = new Scanner(new File("assets/foo.txt");

in.next();      // Read the next String
in.nextInt();   // Read the next int
in.nextFloat(); // Read the next float

If you have spaces in your String s, you should use commas and tell the Scanner to use , s as a delimiter:

Scanner in = ...;
in.useDelimiter(",");
...
