How to set the theme for the application, to avoid wrong color transitions?

Question

Background

I\'m developing a themes chooser feature in my \"app manager\" app, and I\'ve succeeded setting the theme dynamically for each of the activities.

Answer 1

To fix any flickering (action bar, title...) upon app's start, I have set into the manifest

android:theme="@android:style/Theme.NoTitleBar"

for both my main activities (a tab container and a settings activity, from where I switch the themes, based on holo dark and light)

If you use some "launcher activity" or "splash activity" apply Theme.NoTitleBar also for them, then:

having declared Theme.NoTitleBar, for each activity, in onCreate you have to:

1. set the title properly with setTitle(...) and THEN

2. set the theme with setTheme(R.style.CustomAppTheme) BEFORE setContentView(...)
   (and you already do this);

This will prevent the flashing of the action bar/title when switching theme (if done "on-the-fly") and upon app's start.

If you want a custom action bar appearance, this means that the default holo action bar will not flash before yours.
