Resize checkbox image in Android programmatically

Question

I want to resize the image of the CheckBox programmatically, but i want to use the original images of the phone. I just want to scale it. I don't wand to supply own images, because i want to keep the phone's look, and i would still have to scale them. I already tried to get the systems image resources using Setting Android CheckBox to a different image... and then back to the original images but i still could not scale the drawable. (I tried drawable.setBounds()). I'll probably also have this issue with radio buttons. Thanks for your help!

Answer 1

you should just be able to set the layout parameters on the checkBox:

LayoutParams lp = findViewById(R.id.chk_id).getLayoutParams();
lp.width = width;
lp.height=height;
findViewById(R.id.chk_id).setLayoutParams(lp);

By getting the layoutparams before you presever any other layout setting associated with the view

width and height are in pixels, to scale it for density use:

DisplayMetrics dm = new DisplayMetrics();
        getWindowManager().getDefaultDisplay().getMetrics(dm);
        int width = (int)(150*dm.density);

you need to use the Container class for the Layout params this example is for a FrameLayout but just replace that with tyhe type of the parent container.
