java - Spinner with list view -
i ask, i'm working spinner. i've list view , spinner. in spinner declare "month", "june","july","august","sept","oct","nov","dec"
in list view, originally, empty. when click on "august" , show data of august(august.java) in list view, may know there way it?
because right , i'm doing via class.. meaning, when onclick aug, open new intent. wanted merge 1 class, when click "august", change in list view , not open new intent. there way it?
this code
string [] months = { "june", "july", "august", "septemeber", "november", "december", part of date.java
//spinnerview s1 = (spinner) findviewbyid(r.id.spinner1); arrayadapter<string> adapter = new arrayadapter<string>(this,android.r.layout.simple_spinner_item, months); s1.setadapter(adapter); s1.setonitemselectedlistener(new onitemselectedlistener() { public void onitemselected(adapterview<?> arg0,view arg1, int arg2, long arg3) { int index = s1.getselecteditemposition(); //toast.maketext(getbasecontext(), "you have seleted item :" + months[index] , toast.length_short).show(); } public void onnothingselected(adapterview<?>arg0) {} }); if ( s1.equals("august")) { startactivity(new intent(date.this,mainactivity.class)); } else{ startactivity(new intent(date.this,august .class)); } data code i'm getting. august.java

use following code have tried working fine
