Question

Tag that references current theme in xml causes force close

Answer 1

A:

should look like this

<?xml version="1.0" encoding="utf-8"?>
<com.atraudes.CustomLayout1 xmlns:android="http://schemas.android.com/apk/res/android"
   android:orientation="horizontal" 
   android:layout_height="wrap_content" 
   android:layout_width="fill_parent"
   android:layout_gravity="fill_vertical">
<LinearLayout android:orientation="vertical" 
    android:layout_height="fill_parent"
    android:layout_weight="0" 
    style="@styles/thin_border"
    android:layout_width="wrap_content" />

and your style should by

<style name="thin_boarder>
 <item name="android:background">@drawable/customstyle_button_editing</item>
</style>

I don't understand. That's the same first line I already have in my xml file.

see my edit your style is wrong too

schwiz 2010-10-27 20:23:49

The ? I'm using references an attribute of the currently loaded theme. If I refer to a style directly, though, as you indicate, the xml loads, but the style does not get applied. I need to be able to reference an attribute of the current theme, instead of hard-coding it to a certain style.

Correction: setting style="@styles/thin_border works fine, but trying to reference an attribute of the current theme does not.

post your style, whats on line 7?

schwiz 2010-10-28 00:53:17

The line 7 the error is referring to is in the xml layout. The theme element it's referencing in themes.xml is <item name="thin_border">@drawable/button_ready</item> Thanks for your help schwiz, I appreciate it!

Answer 2

+1 A:

After pulling my hair out over this for the past day (and much longer than that in the past), I figured out the problem. I was setting the theme on the activity before setContent(), which was applying the theme for the activity just fine. I finally figured out that running setTheme() on the context as well fixed the problem. The context holds the theme info, which gets passed to the custom view upon inflation. I assumed that setting the theme on the activity was setting it on the context as well :-/

int customTheme = R.style.customTheme;
setTheme(customTheme);
getApplicationContext().setTheme(customTheme);
setContentView(R.layout.mainactivitylayout);

The only other thing I did differently was during inflation:

v = (CustomLayout1) inflater.inflate(R.layout.customlayout1, parent, false);

parent being a parent layout. This was being done in a ListView adapter, so it was right there :-)
