1. How to detect walking

Hi to all,
I would like to use the accelerometer to detect is a user is walking
or standing. I'm using a kalman filter and now I'm able to detect it
but if a user is standing and moves or shake the phone it seems like
he is moving.
Can anyone help me ?
Have I to use another kind of filter ?

Thanks in advance


2. ProgressDialog Theme - TextColor or Background but not both

I'm tryig to style my ProgressDialogs to have a certain background and
a certain TextColor.

I can set the background of the ProgressDialog content pane (but not
the TextColor) if I define an alterDialogStyle in my main application
theme and invoke the ProgressDIalog using the single arg constructor.

    <style name="ApplicationTheme" parent="android:style/Theme">
        <item name="android:alertDialogStyle">@style/AlertDialogStyle</

    <style name="AlertDialogStyle" parent="@android:style/
        <item name="android:fullDark">@drawable/dialog_background</
        <!--item name="android:textColor">@color/jumblee_yellow</item--
        <item name="android:textAppearance">@style/
AlterDialogTextAppearance</item> <!-- No impact. -->

And I can get the TextColor, but not the background of the
ProgressDialog to display if I instead use the 2 arg constructor of
ProgressDialog and pass in a ProgressDialogTheme.

    <style name="ProgressDialogTheme" parent="android:style/
        <item name="android:textColor">@color/jumblee_yellow</item>
<!-- Colours the ProgressDialog text. -->
        <item name="android:windowBackground">@color/transparent</
item> <!-- Hides the title and just displays the content panel (as
long as background does not have a value) -->
        <!--item name="android:panelBackground">@color/jumblee_purple</
item--> <!-- no impact -->
        <item name="android:background">@color/jumblee_purple</item>
<!-- no impact -->

Any ideas on how using either of these methods I can get both the
TextColor and the Background to display as I want them to?
