How do I click the first item in a spinner using Robotium?

问题

I am having problems scrolling up in a spinner to select the first item in a Robotium test case. Here is my code:

int pos = solo.getCurrentSpinners().get(0).getSelectedItemPosition();
solo.pressSpinnerItem(0, 0 - pos);

pos is 1 when I debug, but Robotium still presses the spinner on index 1 even though I order it to press on -1. What am I doing wrong?

Thanks Markus

Seems they took those classes out now. Just ran into this myself but found a way to do this properly and generically.

// 0 is the first spinner in the layout
View view1 = solo.getView(Spinner.class, 0);
solo.clickOnView(view1);
solo.scrollToTop(); // I put this in here so that it always keeps the list at start
// select the 10th item in the spinner
solo.clickOnView(solo.getView(TextView.class, 10));

The API to use here with Robotium is rather flaky, so I decided to go down the direct API route:

instrumentation.runOnMainSync(new Runnable() {
    @Override
    public void run() {
        Spinner spinner = (Spinner) solo.getView(resourceId);
        spinner.setSelection(position, true);
    }
});

This won't show you the popup of the Spinner, but it will select the desired item.

are you able just to get the view and call the perform click on it?

solo.getCurrentSpinners().get(0).performClick()
