从应用程序中包含的文件加载android数组

Question

I've been searching and can't get a clue on how to do this. I'm creating a block-based game, let's say 3x3 blocks on screen, each block has a int associated to know which type it is:

int[][] blocksArray = {
    { 0, 0, 0 }
    { 0, 0, 1 }
    { 0, 0, 0 }
};

What I basically want to do is save like 50 multi-dimensional arrays like this one into a file let's say "levels.txt" just like this:

int[][] level1 = {
    { 0, 0, 0 }
    { 0, 0, 1 }
    { 0, 0, 0 }
};
...
int[][] level50 = {
    { 0, 0, 0 }
    { 0, 0, 0 }
    { 0, 0, 0 }
};

Is this a good way of approaching the problem? Are there better methods?

I really don't want to make a string of my arrays and save them into shared prefs, because I will need to edit a lot of level arrays manually and I want to have this format, or maybe a very similar way to do it?

You can save your arrays in a file using java.io.ObjectOutputStream();

    ObjectOutputStream oos = new ObjectOutputStream(new FileOutputStream("file"));
    oos.writeObject(level1);
    ...
    oos.writeObject(level50);

and then read your arrays back:

    ObjectInputStream ois = new ObjectInputStream(new FileInputStream("file"));
    level1 = (int[]][])ois.readObject();
    ...
    level50 = (int[]][])ois.readObject();

If it is really what you want
