QUESTION
I have an app in which I use AppCompatDelegate and values-night.xml to switch to a Dark theme in-app programatically. I have a SettingsActivity.java with a SettingsFragment, where I have set an OnSharedPreferenceChangeListener to listen to the respective SharedPreferences values. In the Settings page, I have included a Dark mode setting. On toggling the setting, however, the dark mode does not automatically turn on; instead, I have to exit the SettingsActivity for the app to change mode. Here is my code:
SettingsActivity.java
...ANSWER
Answered 2020-Oct-21 at 10:20It doesn't look like you included any theme-setting logic in your preference change listeners (only in onResume).
Try including AppCompatDelegate.setDefaultNightMode(...) in your listeners.
QUESTION
I am having an issue after placing my fragments into a sub directory with isValidFragment function.
All activities and fragments were previously under:
- app/src/main/java/com/myproject/settings/
They are now located here:
- app/src/main/java/com/myproject/settings/fragments/
After the move and placing import com.myproject.settings.fragments.*; in the SettingsActivity.java that is still located under settings/, isValidFragment is still receiving com.myproject.settings.GeneralSettingsFragment..
While my call to GeneralSettingsFragment.class.getName() is returning the correct com.myproject.settings.fragments.GeneralSettingsFragment.
See isValidFragment below:
ANSWER
Answered 2020-Sep-17 at 15:53If only to my future self..
Using Android Studio none of these worked :
- rebuild
- File->Invalidate Caches
- Delete .idea/ folder and resync project with gradle
What needed to be done was using the gradle menu ( or command line ) use app->Tasks->build->build. This uncovered many issues with renaming in the .xml files where they weren't updated with the correct path ( com.myproject.settings.fragments. ).
QUESTION
We have a PreferenceFragmentCompat, and with a tap on a preference, we want to switch from the current PreferenceFragmentCompat to a new PreferenceFragmentCompat. (To have certain settings on a new screen).
However, regardless of what we have tried, we keep running into the following error:
Fragment declared target fragment that does not belong to this FragmentManager
MainActivity.kt
...ANSWER
Answered 2020-Aug-12 at 01:48When you create a Fragment via the navigation graph, it is a child fragment of the NavHostFragment. It specifically is not the activity's supportFragmentManager. This is why the target fragment isn't found - you're using the wrong FragmentManager.
However, you should not use app:fragment or onPreferenceStartFragment when you're using Navigation. Instead, your PreferencesFragment1 should set a click listener on your Preference and have it call navigate() directly.
