Selecting the first item programmatically

[jeffguo17]

How do you select the first item in the spinner?

I tried doing the following,

spinner.setOnItemListeners(..){ ... };

spinner.setSelectedIndex(2);
spinner.setSelected(true);

but it doesn't seem to be working.

Thanks!

spinner.setSelectedIndex(int) should select that item. Make sure you invoke this method after setting the items in the spinner. For example, if I set the selected index to 1 in the sample, then "Jelly Bean" would be selected instead of "Ice Cream Sandwich".

MaterialSpinner spinner = (MaterialSpinner) findViewById(R.id.spinner);
spinner.setItems("Ice Cream Sandwich", "Jelly Bean", "KitKat", "Lollipop", "Marshmallow");
spinner.setSelectedIndex(1); // <--- Set the item programmatically
spinner.setOnItemSelectedListener(new MaterialSpinner.OnItemSelectedListener<String>() {

  @Override public void onItemSelected(MaterialSpinner view, int position, long id, String item) {
    Snackbar.make(view, "Clicked " + item, Snackbar.LENGTH_LONG).show();
  }
});
spinner.setOnNothingSelectedListener(new MaterialSpinner.OnNothingSelectedListener() {

  @Override public void onNothingSelected(MaterialSpinner spinner) {
    Snackbar.make(spinner, "Nothing selected", Snackbar.LENGTH_LONG).show();
  }
});

The method setSelectedIndex just chooses the item to appear as the first item, but I would like to actually select the item as if it would call on onItemSelected.

Thanks again, very nice spinner!

You should just run whatever code is in your listener when you select the item. I don't know why this would be needed. If you really feel like this is necessary please provide an example.

what he means is that when he use spinner.setSelectedIndex(1);,it justchoose the item to appear as the first item,but it didn't execute the selected event.
I have the same problem,please fix that to make this project better.Thanks man.very nice Spinner!
