android - Decrease the size of the radio button icon -


i progrmatically creating radio button, , works fine,

radioimagebutton radioimagebutton = new radioimagebutton(this);     radioimagebutton.setgravity(gravity.center);     radioimagebutton.setid(buttonid);     radioimagebutton.settextcolor(color.black);    radioimagebutton.setcompounddrawableswithintrinsicbounds(icon, null,null, null)// use set icon     radioimagebutton.setbackgrounddrawable(drawable);     radiogroup.layoutparams radioimagebuttonparams = new radiogroup.layoutparams(linearlayout.layoutparams.match_parent,         linearlayout.layoutparams.match_parent, 1f);     radioimagebuttonparams.setmargins(0, 0, 1, 0);      radiogroup.addview(radioimagebutton, radioimagebuttonparams);

in radioimagebutton class

drawable image;      public radioimagebutton(context context) {     super(context);     setbuttondrawable(android.r.color.transparent);     }      @override     protected void ondraw(canvas canvas) {     super.ondraw(canvas);      if (image != null) {         image.setstate(getdrawablestate());          final int verticalgravity = getgravity() & gravity.vertical_gravity_mask;         final int height = image.getintrinsicheight();          int y = 0;          switch (verticalgravity) {         case gravity.bottom:         y = getheight() - height;         break;         case gravity.center_vertical:         y = (getheight() - height) / 2;         break;         }          int buttonwidth = image.getintrinsicwidth();         int buttonleft = (getwidth() - buttonwidth) / 3;         image.setbounds(buttonleft, y, buttonleft + buttonwidth, y + height);         image.draw(canvas);     }     }

but icon being displayed big , need decrease size of icon. have tried setheight not working.

    radioimagebutton.setcompounddrawableswithintrinsicbounds(icon, null,null, null) used set icon

ok fixed myself , here answer

private drawable resize(drawable image) {     bitmap b = ((bitmapdrawable)image).getbitmap();     bitmap bitmapresized = bitmap.createscaledbitmap(b, 50, 50, true);// filter attribute set true     return new bitmapdrawable(bitmapresized); }

the code above modify size of drawable, , make sure filter attribute set true icons not blur.

hope helps 1 in future. happy coding :)
