Similar to another answer, but you can use an ArrayAdapter to populate based on an Enum class. I would recommend overriding toString in the Enum class to make the values populated in the spinner more user friendly. In the activity: Spinner mySpinner = (Spinner) findViewById(R.id.mySpinnerId); mySpinner.setAdapter(new ArrayAdapter<MyEnum>(this, android.R.layout.simple_spinner_item, MyEnum.values())); Your enum class: public enum MyEnum{ … Read more
A cleaner solution, in my opinion, to differentiate between programmatic and user-initiated changes is the following: Create your listener for the spinner as both an OnTouchListener and OnItemSelectedListener public class SpinnerInteractionListener implements AdapterView.OnItemSelectedListener, View.OnTouchListener { boolean userSelect = false; @Override public boolean onTouch(View v, MotionEvent event) { userSelect = true; return false; } @Override public … Read more

Here is a working solution: Instead of setting the spinner’s OnClickListener, we are setting OnTouchListener and OnKeyListener. spinner.setOnTouchListener(Spinner_OnTouch); spinner.setOnKeyListener(Spinner_OnKey); and the listeners: private View.OnTouchListener Spinner_OnTouch = new View.OnTouchListener() { public boolean onTouch(View v, MotionEvent event) { if (event.getAction() == MotionEvent.ACTION_UP) { doWhatYouWantHere(); } return true; } }; private static View.OnKeyListener Spinner_OnKey = new View.OnKeyListener() { … Read more
This is quite an old question, but I think still relevant, so here’s my answer: Simplest Method lencinhaus answer is correct. It works, but it can be done in an even simpler way: Just add another background to it. The example below uses the standard Button background for a more homogeneous look-and-feel: <Spinner android:id=”@+id/my_spinner” android:layout_width=”wrap_content” … Read more
To hide an arbitrary item or more than one item I think that you can implement your own adapter and set the index (or array list of indexes) that you want to hide. public class CustomAdapter extends ArrayAdapter<String> { private int hidingItemIndex; public CustomAdapter(Context context, int textViewResourceId, String[] objects, int hidingItemIndex) { super(context, textViewResourceId, objects); … Read more
use: switch(parent.getId()) { … } instead is what you need. The view in your parameter is the actual ‘row’ (i.e. the clicked child of spinner item), and the parent is the actual ‘spinner’ that you are after.
public void onItemSelected(AdapterView<?> parent, View view, int pos, long id) { if(parent.getId() == R.id.spinner1) { //do this } else if(parent.getId() == R.id.spinner2) { //do this } }
In your SpinnerAdapter: @Override public View getView(int position, View convertView, ViewGroup parent) { View view = super.getView(position, convertView, parent); view.setPadding(0, view.getPaddingTop(), view.getPaddingRight(), view.getPaddingBottom()); return view; }
There are a few solutions in this thread Creating a setError() for the Spinner: The EdmundYeung99‘s one works for me, either you are using your own adapter or not. Just put the following code in your validate function: TextView errorText = (TextView)mySpinner.getSelectedView(); errorText.setError(“”); errorText.setTextColor(Color.RED);//just to highlight that this is an error errorText.setText(“my actual error text”);//changes … Read more
