I've created a PreferenceActivity that allows the user to choose the theme he wants to apply to the entire application.
When the user selects a theme, this code is executed:
if (...) {
getApplication().setTheme(R.style.BlackTheme);
} else {
getApplication().setTheme(R.style.LightTheme);
}
But, even though 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?
Should I call setTheme
at any special point in the code? My application consists of several Activities if that helps.
I would like to see the method too, where you set once for all your activities. But as far I know you have to set in each activity before showing any views.
For reference check this:

Edit (copied from that forum):
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Call setTheme before creation of any(!) View.
setTheme(android.R.style.Theme_Dark);
// ...
setContentView(R.layout.main);
}
Edit
If you call setTheme
after super.onCreate(savedInstanceState);
your activity recreated but if you call setTheme
before super.onCreate(savedInstanceState);
your theme will set and activity
does not recreate anymore
protected void onCreate(Bundle savedInstanceState) {
setTheme(android.R.style.Theme_Dark);
super.onCreate(savedInstanceState);
// ...
setContentView(R.layout.main);
}
