graphics - Android : Looping through big numbers of ImageButtons -

i applying images imagebuttons in code, i'm wondering if there better way shown in example. know it's not correct way can take way time large numbers of views.

    btn1.setimageresource(r.drawable.plus);     btn2.setimageresource(r.drawable.plus);     btn3.setimageresource(r.drawable.plus);     btn4.setimageresource(r.drawable.plus);     btn5.setimageresource(r.drawable.plus);  btn1.setadjustviewbounds(true);     btn1.setpadding(0,0,0,0);     btn2.setadjustviewbounds(true);     btn2.setpadding(0,0,0,0);     btn3.setadjustviewbounds(true);     btn3.setpadding(0,0,0,0);     btn4.setadjustviewbounds(true);     btn4.setpadding(0,0,0,0);     btn5.setadjustviewbounds(true);     btn5.setpadding(0,0,0,0); 

you need root view in activity, cast viewgroup, children, check type , update accordingly. namely follows,

viewgroup rootview = (viewgroup) findviewbyid(android.r.id.content); int children = rootview.getchildcount(); (int = 0; < children; i++) {     view view = rootview.getchildat(i);     if (view instanceof imagebutton) {         ((imagebutton) view).setimageresource(r.drawable.plus);         ((imagebutton) view).setadjustviewbounds(true);         ((imagebutton) view).setpadding(0,0,0,0);     } }
