you use alert builder this:

    alertdialog.builder builder;     if (build.version.sdk_int >= build.version_codes.lollipop) {         builder = new alertdialog.builder(context, android.r.style.theme_material_dialog_alert);     } else {         builder = new alertdialog.builder(context);     }     builder.settitle("delete entry")     .setmessage("are sure want delete entry?")     .setpositivebutton(android.r.string.yes, new dialoginterface.onclicklistener() {         public void onclick(dialoginterface dialog, int which) {              // continue delete         }      })     .setnegativebutton(android.r.string.no, new dialoginterface.onclicklistener() {         public void onclick(dialoginterface dialog, int which) {              // nothing         }      })     .seticon(android.r.drawable.ic_dialog_alert)     .show();
