Using NumberPicker in Android 3

I'm trying to use the NumberPicker widget in Android 3.1. I figure it is now a standard widget, part of a public API, and not an internal widget anymore. However, it doesn't work. I can see a textEdit with "0" in it, but there are no buttons, I can't scroll it, and I can't enter a new number with keyboard, either.

Update:

Here's the xml I used for testing:

    <NumberPicker
        android:id="@+id/numberPicker1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

</LinearLayout>

By saying doesn't work I mean this: it doesn't have arrows displayed (see the screenshot), and on emulator the keyboard doesn't show up. On a real device it does, but I can't type in the text, I can only erase it.

Any suggestions? I really hate to write my own widget when there is a standard one.

Solution

  • Try to set the values that are possible in the NumberPicker via

    setMaxValue setMinValue or setDisplayedValues

    maybe the NumberPicker is not working if it doesn't know which values to display.
