Android - How to get the selected item value from a spinner and put it into a string? -

-

I have read many questions on this thread, but none of them help me ... this is my code Is: @ override protected void build (bundle saved instainstate) {super. Connet (Saved Instantstate); SetContentView (R.layout.activity_main); Spinner Spinner = (Spinner) Find VViBiID (RID.imc-spinner); // string array and a default spinner layout ArrayAdapter & lt; Charsequence & gt; Create an array adapter using Adapter = Arrayadaptor.Creatofrom Resource (This, R. Ram.ImcAir, AndroidR.Let.Simple_spinner_item); // Specify the layout to use when adapter.setDropDownViewResource (android.R.layout.simple_spinner_dropdown_item) appears on the list; // Adapter spinner spinner. Apply to the adapter; } Selected items on public zeros (adapterview & lt;? & Gt; parent, view view, integer, long id). You can retrieve the selected items using imc_met = parent.getItemAtPosition (pos) .toString (); }

I imc_met to public string imc_met; I declare as . The problem is that imc_met does not include the value of the spin of selected items, but it is null ...

Where is the problem?

Thx in advance

After

.

imc_met = Spinner.getSelectedItem () toString ();

Instead of:

imc_met = parent.getItemAtPosition (POS) .toString ();

updated:

It takes you not telling listeners to spin correctly, a function like below: 

  spin.setOnItemSelectedListener (new OnItemSelectedListener () {@Override public void onItemSelected (AdapterView & LT ;? & gt; arg0, see ARGl, integer aRG2, long arg3) {string imc_met = spin.getSelectedItem ( ) toString () ;.} @Override public void onNothingSelected (AdapterView & LT ;? & gt; arg0) {/ / TODO auto-generated method stub}});

After opening several examples of macro / code written, I suddenly get stuck with a code that seems safe. Solver (SOLVER.XLAM) is doing this notation and I would like to remove it from my system. I do not think this is a relativant code. Can anyone tell me what should I do? I have already installed something to remove the password but Solver is still asking for password and I can not get rid of it! itemprop = "text"> Solver Excel is add-in If you want to delete it, then Excel Application & gt; Options & gt; Add-ins & gt; Search for 'Go to' button and gt; Uncheck the solver on the list like press something (I can not give you the exact path because I have the Polish version of Excel). Trying to open Solver's VBA code is not good because it There is allegedly copyright. Besides, I do not think Solver creates any disadvantages while working with Excel or VBA.

github - Teamcity & Git - PR merge builds - anyway to get HEAD commit hash? -

-
I have a team city build project with Gitbab VCS route, I have been triggered for both / head on PR and / Merge the referee. The annoying thing is that you can not do anything useful with the merged hash - it is not present in Gitobb. I want to exclude newsgate packages with head in gutub comet situations in the version number along with Hewash (Newsaging 7) for the music build, but against head hash. However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge. (PR - Pull Request) This command works reliably while running One on / merge is git log --no-merge -1 ---- = '% h'

I try the replacement range: with text for a week but still stuck. Not to know how to use it to replace it in your case. Please guide! Thanks in advance! This is an important job.
