Android: how to disable top left back button from SubSettings

问题

From Android Jellybeans, all sub-activities of Settings activity are having this back button at top left corner which calls the Settings activity. It behaves more like a 'up' button for navigation purpose.

I have android code, and I want to disable this button for few sub-activities like display, sound etc. in my build.

Any suggestions, where do I have to modify to disable this? I tried out removing

android:parentActivityName 

tag from particular Activity in the Manifest file, but it didn't work.

回答1:

Try this

getActionBar().setDisplayHomeAsUpEnabled(false);
