问题 I would hide navigation bar and action bar of my app after some second that display don't get touched, and expand current view to fullscreen. Then if user touch the screen (or better if he swipe down), make visible both again. How to? 回答1: You can use a Handler to delay certain actions. Handler h = new Handler(); h.postDelayed(new Runnable() { @Override public void run() { // DO DELAYED STUFF getActionBar().hide(); } }, delaytime); // e.g. 3000 milliseconds The actions you take inside the run

How does NavUtils.navigateUpFromSameTask work?

由 左心房为你撑大大i 提交于 2019-12-10 15:26:20
问题 please what is actuall behavior of this method? I thought that when bind this method call to my actionbar back button and also set the homepageactivity name in Manifest.xml, it should be then opened after the click in the button - regardless of the current task stack.. For example, when I open my Activity from widget, the parent Activity is not in BackStack - this is what I want to solve..I know I can somehow build my own taskstack, but I just thought, that this should be prebaked solution,

Pass data back to previous fragment using Android Navigation

问题 I've started using Android Architecture Components (Navigation and Safe Args, View Models) along with Koin library. Currently, I've got a problem with passing arguments between two fragments - I need to pass a string value from fragment A to fragment B, modify this value in fragment B and pass it back to fragment A. I've found one possible solution to my problem - shared view models. Unfortunately, this approach has one problem because I can pass and modify values between screens, but when

Is navigation in iosched 13 application correct?

Navigation with Up and Back buttons is quite complicated (at least for me) As the android documentation states, You have the ability to make the Up behavior even smarter based on your knowledge of detail view. Extending the Play Store example from above, imagine the user has navigated from the last Book viewed to the details for the Movie adaptation. In that case, Up can return to a container (Movies) which the user hasn't previously navigated through. http://developer.android.com/design/media/navigation_between_siblings_market2.png I am exploring Google IO 2013 application for best practices
