Create a Bitmap/Drawable from file path

Question

I\'m trying to create a Bitmap or Drawable from existing file path.

String path = intent.getStringExtra(\"FilePath\");
BitmapFactory.Options option = new Bit         


        

Answer 1

you can't access your drawables via a path, so if you want a human readable interface with your drawables that you can build programatically.

declare a HashMap somewhere in your class:

private static HashMap images = null;

//Then initialize it in your constructor:

public myClass() {
  if (images == null) {
    images = new HashMap();
    images.put("Human1Arm", R.drawable.human_one_arm);
    // for all your images - don't worry, this is really fast and will only happen once
  }
}

Now for access -

String drawable = "wrench";
// fill in this value however you want, but in the end you want Human1Arm etc
// access is fast and easy:
Bitmap wrench = BitmapFactory.decodeResource(getResources(), images.get(drawable));
canvas.drawColor(Color .BLACK);
Log.d("OLOLOLO",Integer.toString(wrench.getHeight()));
canvas.drawBitmap(wrench, left, top, null);
