java - Passing array from one android activity to another and using it in a spinner -


in source code, have 2 activities. in activity a.java have array 

private string[] typename = new string[100];

and starting new activity 

    public void loadcuecardset(view view){      intent loadcuecardpage = new intent(this, loadcuecardset.class);     loadcuecardpage.putextra("types", typename);     startactivity(loadcuecardpage); }

in second activity, have 

protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_load_cue_card_set);     // array of choices   // selection of spinner     spinner spinner = (spinner) findviewbyid(r.id.spinner);  // application of array spinner      bundle extras = getintent().getextras();     string colors[] = extras.getstringarray("types"); // doesn't work      arrayadapter<string> spinnerarrayadapter = new arrayadapter<string>(this,   android.r.layout.simple_spinner_item, colors);     spinnerarrayadapter.setdropdownviewresource(android.r.layout.simple_spinner_dropdown_item); // drop down view     spinner.setadapter(spinnerarrayadapter);

i know problem spinner , has array passing it, problem should work because tried actual array created in second activity. code below works if don't use array passed activity.

protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_load_cue_card_set);     // array of choices   // selection of spinner     spinner spinner = (spinner) findviewbyid(r.id.spinner);  // application of array spinner      string colors[] = {"red"}; //works      arrayadapter<string> spinnerarrayadapter = new arrayadapter<string>(this,   android.r.layout.simple_spinner_item, colors);     spinnerarrayadapter.setdropdownviewresource(android.r.layout.simple_spinner_dropdown_item); // drop down view     spinner.setadapter(spinnerarrayadapter);
