Add Multiple Dynamic Spinner Views in Android Activity,Not Loading Selected Spinner Data In second Spinner

Question

In My application i am Having Dynamic Spinners.
Totally 2 Spinners are there in a Method,Both are dependent(SPinner1 ,Spinner2).
I can call that method multiple Times.
Spinner Data Loading from Local database.

Problem:

i called that method twice So activity Shown Totally 4 Spinners.

       1a.spinner1
       1b.SPinner2

       2a.Spinner1
       2b.Spinner2

Based on 3rd Spinner what i Selected , 4th Spinner data is loading perfectly.

but based on 1st Spinner Selected item data Not showing in 2nd Spinner, because last iteration data(3rd and 4th spinner)only stored in String Array.

Please Help me to Solve this. show data in all the spinners.

Your code is too much complicated for the given task in hand. It is a two method work. First method would add a spinner to existing arraylist of spinners and the second implements the onItemSelected listener for that array of spinners. Having ArrayList> would be good for holding data for each spinner. — Atif Rehman, Jun 06 '16 at 06:32
i holding data in array list not a problem,it should reflect data in 2nd dependent Spinner,based on 1st Spinner selected,Even we r creating Multiple Dynamic Views. — Kumar, Jun 06 '16 at 07:08

I haven't not tested this. Hope it help you.

Thanks For Your Reply :) But in my side Based on the Spinner1 selection Spinner2 Data will be Loading from the Local database. — Kumar, Jun 06 '16 at 10:29
yes, selected spinner is applied in for loop. according to main spinner it will load the data to dependentSpinner — Mohammad nabil, Jun 06 '16 at 10:33
Read my Problem Properly and this thing will Work or not.because Just adding Hard coded values it may work. i want to Use that Method Multiple times based on the Database valueid from First Spinner,then load the Second Spinner data. — Kumar, Jun 06 '16 at 11:19
also first Spinner data length is Not Constant,based on local db String Data. — Kumar, Jun 06 '16 at 11:21
No one will give exact answer to your question, they only show you a way. — Mohammad nabil, Jun 06 '16 at 11:22

before adding views to mContainerView.addView(rowView123); first remove the previous child views.

//snippet.

//remove all views
mContainerView.removeAllViews();
//add new views
mContainerView.addView(rowView123);
