android-tablayout

问题 I'm trying to remove the shadow below tabs while using TabLayout, which is defined in a normal layout (and not as a part of a toolbar or actionbar). Setting theme as <item name="android:windowContentOverlay">@null<item/> or <item name="windowContentOverlay">@null<item/> didn't work. Also, setting elevation to 0 didn't help either. <android.support.design.widget.TabLayout xmlns:app="http://schemas.android.com/apk/res-auto" android:id="@+id/sliding_tabs" android:layout_width="match_parent"

问题 I currently have a DrawerLayout in my main.xml. There's a Toolbar wrapped in an AppBarLayout, and then a simple LinearLayout to swap out fragments. One of the fragments I navigate to, I want it to contain a TabLayout for a ViewPager of fragments.

I also don't want to use setElevation() because it won't work for pre

问题 I've realized when using a tab layout in Android it always loads the tabs touching it, i.e. the tab before and the tab after so it is loaded when you page to it. However, I load lots of content and images from a server and this causes a lot of data and memory use and I often get OOM errors , I am displaying the images efficiently using Glide. Basically I need to know 3 things: How can I stop the tab layout loading any pages other than the current one How to clear/recycle/delete an old tab
