推荐答案

    int width = 200;
    int height = 100;
    Bitmap bitmap = Bitmap.createBitmap(width, height, Config.ARGB_8888);
    Canvas canvas = new Canvas(bitmap);

    Paint paint = new Paint();
    paint.setColor(Color.BLACK); 
    paint.setStyle(Paint.Style.FILL);       
    canvas.drawPaint(paint);

    paint.setColor(Color.WHITE);
    paint.setAntiAlias(true);
    paint.setTextSize(14.f);
    paint.setTextAlign(Paint.Align.CENTER);
    canvas.drawText("Hello Android!", (width / 2.f) , (height / 2.f), paint);

然后执行您想对位图进行的所有操作.例如:

And then do whatever you wanted to do with the Bitmap. For example:

ImageView image = new ImageView();
image.setImageBitmap(bitmap);
