android - custom AlertDialog view.onClickListener does not work properly -

i'm adding colors.xml alertdialog , want respond, when 1 of views clicked. dialog displayed , when performclick() on 1 of views works. when try run on phone , click hand listener not triggered although should be.

here's code:

my mainactivity.java

alertdialog.builder builder = new alertdialog.builder(this); builder.settitle("pick color"); builder.setcancelable(true); flexboxlayout fl_colors = (flexboxlayout) layoutinflater.inflate(r.layout.colors,null); builder.setview(layoutinflater.inflate(r.layout.colors,null));  final alertdialog alert = builder.create();  for(int i=0;i<fl_colors.getchildcount();i+=1){     view v_color = fl_colors.getchildat(i);     log.d("debug",v_color.tostring()); // logs element like: android.view.view{a7d0c87 v.ed..... ......i. 0,0-0,0 #7f0d00a6 app:id/btn_6}     v_color.setonclicklistener(new view.onclicklistener(){         @override         public void onclick(view v) {             string color = (string) v.gettag();             log.d("debug",color);              alert.dismiss();         }     }); }  builder.show(); 

and colors.xml

because not use inflated view. replace

builder.setview(layoutinflater.inflate(r.layout.colors,null)); 

with

builder.setview(fl_colors);
