Help about creating images inside classes

[Matt Boss]

I'm trying to learn java for android -- after many years coding AS3 for flash.

I'm using Android studio.
I've gone through a bunch of tutorials but all of them either: Draw shapes/bitmaps directly in the main class OR Create references to a shape (Rect or something) in a secondary class then use a getRect command from the main class and THEN draw the image (but none have done this with a bitmap image so far) OR Use the xml layout tools and create no images through code at all.

Can someone explain to me (or point me in the direction of a tutorial) how I can create images inside subclasses (and what those classes would need to extend?)

I have a MainActivity class and a GameView class which I have copied from one of the tutorials I've done. I removed what the GameView was drawing, but kept everything else.
Instead I have it looking like this:

    public GameView(Context context) {
        // Initialize our every game variables
        super(context);
        ourHolder = getHolder();
        paint = new Paint();
        WindowManager wm = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);
        Display display = wm.getDefaultDisplay();
        Point size = new Point();
        display.getSize(size);
        screenX = size.x;
        screenY = size.y;
        [b]createTileHolder();[/b]
    }
[b]    public void createTileHolder() {
        TileHolder tempTile = new TileHolder(getContext());
        tempTile.setMax(screenX,screenY);
        tempTile.setTiles(curQuote,curLength);
[/b]    }

This works fine.

public class TileHolder extends GridLayout{

    private String TAG = "TileHolder";
    private double maxWidth;
    private double maxHeight;
    private int tileSize;
    private Context upContext;

    public TileHolder(Context context) {
        super(context);
        upContext = context;
    }
    public void setMax(int screenX,int screenY) {
        maxWidth = screenX*.8;
        maxHeight = screenY*.8;
    }
    public void setTiles(String quote, int columns) {
        setColumnCount( columns );
        while(quote.length() % columns != 0) {
            quote = quote + " ";
        }
        setRowCount( quote.length() / columns );
        tileSize = (int)maxWidth / getColumnCount();
        if((getRowCount()*tileSize*2) > maxHeight) {
            tileSize = (int)(maxHeight / getRowCount());
        }
        for(int j = 0; j < quote.length(); j ++) {
            Tile tempTile = new Tile('-',tileSize);
        }
        for(int i = 0; i < quote.length(); i ++) {
            Tile tempTile = new Tile(quote.charAt(i),tileSize);
        }
    }
}

The above works fine, although I'm not sure if GridLayout is what I want to be extending. I think it is because after I make the tiles I want them to be arranged in the GridLayout position.

public class Tile {
    final private char SPACE = ' ';
    SurfaceHolder ourHolder;
    Canvas canvas;
    Paint paint;
    private char myChar;
    private int mySize;
    private String TAG = "Tile";
    Bitmap bitmapTile;

    public Tile(char letter, int size) {
        super();
        myChar = Character.toUpperCase(letter);
        mySize = size;
        [b]bitmapTile = BitmapFactory.decodeResource(getResources(), R.drawable.tile);[/b]
        makeSquare();
        makeLetter();
    }
    private void makeSquare() {
    }
    private void makeLetter() {

    }
}

This class is the one giving me trouble.
First, I don't know what to extend. In AS3 I would extend Sprite and just do all my drawing right inside this object.
Second, I don't know how to draw from this class into the main view. Trying to get a bitmap like it currently is doesn't work because it doesn't see the resources.
I want each instance of "Tile" to have the view of my tile.png overlayed with a text field holding 'myChar'.
Then "TileHolder" should contain all those tiles (in a grid) to be displayed on the screen.

Again.. Can someone explain to me (or point me in the direction of a tutorial) how I can create images inside my Tile class to be displayed by my GameView class?

Welcome to the Ranch

I can never remember what to do with images, but have you tried the Java® Tutorials? There are several pages about images. I think that section is intended for Swing, so it might be different on Android.
