问题 Tab Icons: My current method is to create two files (ic_list_selected_24dp.xml and ic_list_unselected_24dp.xml; they are basically the same but only the android:fillColor='Color HEX CODE' are different), and then create a selector (selector_tabitem_list.xml) to change the drawable color when the state is changed. // @drawable/selector_tabitem_list.xml <selector xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto"> <item android

问题 I'm trying to show a DialogFragment full-screen such that the ActionBar is still visible but the tabs in a TabLayout are hidden. The image on the left is what I've managed to achieve; the image on the right is what I'm aiming for: There are two issues: The tabs are still shown, which the user can interact with; Because of the extra FrameLayout to show the dialog, the ViewPager content is still visible (the FAB button is not part of the dialog). This also means that the user can interact with

The problem is that the indicator of the TabLayout is handing between the two tabs and not moving smoothly when swiping. When searching for a solution I found similar problem that the indicator bounces between tabs, and its solution was to use newer version of the library. I'm using the latest version and facing this problem. 回答1: Get the SlidingTabStrip file here -

问题 My tabLayout is exhibiting this strange behaviour You can see that by swiping the tabs after clicking a row the content from a tab gets mixed with the content from another. Each row in the listView (the gif only shows one row, of course there'd be more) can be clicked to update a value from the database on which the eye icon is based. So, I want the icon to update at the same time. In the activity source file I also declared the PagerAdapter for the fragment tabs, the fragment and the

问题 So I have implemented Tab layout with ViewPager in my app. Each tab shows a fragment. Now I want to open a new fragment(lets call it B) from one of these fragments in the tab layout(lets call it A). So A is in tab layout but I want B to take up whole screen. I am even able to do it but I am facing little problem. The new fragment doesn't take up the whole screen.

问题 I have a viewpager with undetermined pages, because the user can add pages too. Thats okay, but I have no idea how to make it possible, that my user could delete those pages. I have tried to implement a long click listener on every tab with the code below, but it is not working.
