I think what you are looking for is: [UIApplication sharedApplication].networkActivityIndicatorVisible = YES; Swift 3 UIApplication.shared.isNetworkActivityIndicatorVisible = true as doc’d here: https://developer.apple.com/documentation/uikit/uiapplication/1623102-isnetworkactivityindicatorvisibl
You can do that in Tools / Options and then Environment / Fonts And Colors and there is a setting for visible White Space :
By design, RefreshIndicator works with ListView. But if you want to use RefreshIndicator with non-scrollable-widgets, you can wrap your widget into Stack with ListView: RefreshIndicator( onRefresh: () {}, child: Stack( children: <Widget>[ListView(), YOUR_CHILD_WIDGET], ), ),
Create: spinner = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge]; [spinner setCenter:CGPointMake(kScreenWidth/2.0, kScreenHeight/2.0)]; // I do this because I’m in landscape mode [self.view addSubview:spinner]; // spinner is not visible until started Start: [spinner startAnimating]; Stop: [spinner stopAnimating]; When you’re finally done, remove the spinner from the view and release.
setIndicatorBounds(int, int) does not work properly for Android 4.3.

(Trying to redeem myself…) In response to Jared’s comment on @Fabians answer about automating it, note that all you need to supply is a named list of contrast matrices. contrasts() takes a vector/factor and produces the contrasts matrix from it. For this then we can use lapply() to run contrasts() on each factor in our … Read more
All we need are: ViewPager, TabLayout and 2 drawables for selected and default dots. Firstly, we have to add TabLayout to our screen layout, and connect it with ViewPager. We can do this in two ways: Nested TabLayout in ViewPager <androidx.viewpager.widget.ViewPager android:id=”@+id/photos_viewpager” android:layout_width=”match_parent” android:layout_height=”match_parent”> <com.google.android.material.tabs.TabLayout android:layout_width=”match_parent” android:layout_height=”wrap_content”/> </androidx.viewpager.widget.ViewPager> In this case TabLayout will be automatically … Read more
