android - set Custom Programatically created drawable to radioButton for states -

i wanted set programatically created drawable radio button checked , unchecked states, not working code follows,

code draw rectangular box,

public static gradientdrawable squareview(int backgroundcolor, int bordercolor) {     gradientdrawable shape = new gradientdrawable();     shape.setshape(gradientdrawable.rectangle);     //shape.setcornerradii(new float[] { 8, 8, 8, 8, 0, 0, 0, 0 });     shape.setcolor(backgroundcolor);     shape.setstroke(3, bordercolor);     return shape; } 

code set programatically created view(squareview) set stated radiobutton,

public static void setchecked_selector(context context,radiobutton view) {     try {         drawable pressed=squareview(contextcompat.getcolor(context,r.color.colorblue),contextcompat.getcolor(context,r.color.colorred));//new badgedrawable(context,colorpressed);         drawable normal=squareview(contextcompat.getcolor(context,r.color.colorwhite),contextcompat.getcolor(context,r.color.colorred));          statelistdrawable states = new statelistdrawable();         states.addstate(new int[]{android.r.attr.state_checked,},pressed);         states.addstate(new int[]{android.r.attr.state_pressed}, pressed);          states.addstate(new int[]{android.r.attr.state_checked, android.r.attr.state_enabled}, pressed);         states.addstate(new int[]{android.r.attr.state_checked, -android.r.attr.state_enabled}, pressed);          states.addstate(new int[]{}, normal);         view.setbuttondrawable(states);     } catch (exception e) {     } } 

after little work around, realized issue drawable not have size. i'm not sure size should give adding following line makes radiobutton visible:

shape.setsize(50, 50); 

i suggest put appropriate size in dimens.xml , use instead:

int size = context.getresources().getdimensionpixelsize(r.dimen.radio_button_size); shape.setsize(size, size);
