How to change current Theme at runtime in Android
- by Guido
I've created a PreferenceActivity that allows the user to choose the theme he wants to apply to the entire application.
When the users selects a theme, this code is executed:
if (...) {
getApplication().setTheme(R.style.BlackTheme);
} else {
getApplication().setTheme(R.style.LightTheme);
}
But, despite I've checked with the debugger that the code is being executed, I can't see any change in the user interface.
Themes are defined in res/values/styles.xml, and Eclipse does not show any error.
<resources>
<style name="LightTheme" parent="@android:style/Theme.Light">
</style>
<style name="BlackTheme" parent="@android:style/Theme.Black">
</style>
</resources>
Any idea about what could be happening and how to fix it? Thank you.
