xml - Android style dosen't work -


i trying add specific style button, issue it's works in themes.xml when write :

themes.xml

    <style name="apptheme" parent="theme.appcompat.noactionbar">      <item name="colorcontrolhighlight">@color/background</item>     <item name="colorbuttonnormal">@color/white</item>    </style>

mylayout.xml

 <button     android:id="@+id/play"     android:layout_width="match_parent"     android:layout_height="50dp"     android:layout_alignparentbottom="true"     android:gravity="center"     android:text="play"     android:textcolor="@color/guillotine_background"     android:textsize="25dp"     android:textstyle="bold"/>

but don't same result when use :

styles.xml

 <style name="mycolorbutton" parent="apptheme">         <item name="colorcontrolhighlight">@color/background</item>         <item name="colorbuttonnormal">@color/white</item> </style>

i added line button tag in mylayout.xml

mylayout.xml

  style="@style/mycolorbutton"

isn't must return same result ?

colorcontrolhighlight , colorbuttonnormal theme attributes. styles used themes activity. not attributes of button. if want use on button not whole activity, use android:theme attribute instead:

<button     android:theme="@style/mycolorbutton"     ... />

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
