When i create an activity that uses a custom-theme, e.g.
android:theme="@style/MyLogonTheme".
I create my theme in styles.xml:
<style name="MyLogonTheme" parent="android:Theme">
<item name="android:typeface">sans</item>
<item name="android:windowBackground">@drawable/
android_screen_logon_bg</item>
</style>
(note that i have a few more themes and plenty more styles in
styles.xml, but they are not in use for this particular activity).
When the activity is started brand new (e.g. after the process has
just started), it starts VERY slowly:
1. The background (windowBackground) appears quickly, in a timely
manner and the activity's 'setContentView' is called almost
immediately in the onCreate.
2. However, the activity's content-view (setContentView) finally shows
up 0.5 - 2 seconds later (depending on the speed of the phone)!
When i remove the 'parent' from MyLogonTheme's definition:
<style name="MyLogonTheme">
<item name="android:typeface">sans</item>
<item name="android:windowBackground">@drawable/
android_screen_logon_bg</item>
</style>
Both the background and the content-view appear quickly!
Somehow, including the inheritance from the "android:Theme" slows
things down quite considerably.
Why is this the case?
Is there a way around it?
I looked at the log... no special output that may indicate
something... it is just slow.
BTW:
If i do remove the parent="android:Theme" part, things do load/show
quickly, but i get quite a few warnings in the log. The warnings
complain about layout_height is missing and some ColorStateList with
TypedValue (0x2/0x1010059 a=-1) can not be found. They are just
warnings... i see no other side effects.
If i specify the parent="android:Theme", I don't get these warnings.
Can I just remove the parent="android:Theme" part and live with the
warnings?
Thanks!
