有什么办法可以通过编程方式设置微调器的名称？

Question

I've been trying to figure this one out for a while now, but no matter how much I look, I haven't found an answer. So far I've checked the following questions: Set selected item of spinner programmatically , How to set selected item of Spinner by value, not by position? , and How to set position in spinner? . So far none of them have worked for me. I'm trying to do this on Android 4.4.2, and here's my code:

String dataReturned11 = someData.getString("unitCheckFour", "degrees F");
if (dataReturned11 == ("degrees C")) {
    tempUnits.setSelection(((ArrayAdapter<String>)tempUnits.getAdapter()).getPosition("degrees C"));
} else {
    tempUnits.setSelection(((ArrayAdapter<String>)tempUnits.getAdapter()).getPosition("degrees F"));
};

What I'm trying to do is set it based on a value that was saved earlier, and it doesn't seem to be working. An important thing to note is that this gave me an unchecked cast warning, so I suppressed it. It does not seem to have had any effect on my problem whatsoever.

EDIT: Since it was asked for, here is the code behind the spinner itself:

tempUnits = (Spinner) findViewById(R.id.tempUnits);
ArrayAdapter<CharSequence> adapter4 = ArrayAdapter.createFromResource(this,
    R.array.tempUnits, android.R.layout.simple_spinner_item);
adapter4.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
tempUnits.setAdapter(adapter4);

I hope this helps.

Answer 1

yes you can .

 for (int i=0;i<projectArray.size();i++)
    {
        if (projectArray.get(i).getName().equals(tasksArray.get(position).getProject()))
        {
            project.setSelection(i);
            return;
        }
    }
