Answer 1

create a custom dialog box in separate class from following code`

public class CustomeDialog {
    Context context;
    public CustomeDialog(Context context) {
        this.context = context;
    }
public void creatDialogBoxWihList() {
         final Dialog dialog = new Dialog(context);
         dialog.getWindow().setType(WindowManager.LayoutParams.TYPE_SYSTEM_ALERT);
         dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
         dialog.setCancelable(false);
         dialog.setContentView(R.layout.dialog_layout);
       // dialog.getWindow().setBackgroundDrawable(null);  //for making dialog to fill window completely

         Button ok = (Button) dialog.findViewById(R.id.ok);
         Button cancel = (Button) dialog.findViewById(R.id.can);

         ok.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                dialog.dismiss();
            }
         });

         dialog.show();
         Window window = dialog.getWindow();

        window.setLayout(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
   }}
