问题 CorodinatorLayout inside another CoordinatorLayout such that scrolling the child-view should also scroll the Parent CoordinatorLayout . I have a coordinatorLayout with ViewPager that contains different Fragment such that on Scroll will hide the tabLayout I have another coordinatorLayout that has a viewPager . This fragment is inflated in ViewPager of parent fragment(parent Coordinator layout ). The problem is onScrolling the child fragment in childViewpager only reflects in coordinator layout

问题 I used this example to build a layout with two NavigationViews: http://v4all123.blogspot.de/2016/03/simple-example-of-navigation-view-on.html It works fine. But also in the demo on this site you can see, that the Toolbar isn't 100% in the middle. The left button has more space to the left than the right button to the right border. Take a look to the screenshot from Android Studio. I've tried to center each view but the only way to get the same space left and right is to add a padding to the

问题 I have been dealing for a while now with changing the color of the background of the title in the collapsingtoolbarlayout but only when is expanded. Why I want is either have a transparent scrim background or a color overlay (like the documentation says): I want this behaviour (or a protective screen with transparent background is also possible), the thing is I found exactly the same question on this post: Android CollapsingToolbarLayout Title background I've applied this solution to my

问题 I have an AppCompatActivity that contain fragments and it controls the replacing of many fragments. I want to show differents toolbar depending of fragment to show. This is the code for main_activity.xml: <android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/drawer" android:layout_width="match_parent" android:layout_height="match

问题 I have a problem where sometimes the AppBarLayout will not show its full content all the time when you play around with it: <android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" android:layout_width="match_parent" android:layout_height="match_parent"> <android.support.v7.widget.RecyclerView android:layout_width="match_parent" android:layout_height="match_parent" app:layout_behavior="

问题 How can I set the colour of icons (home and overflow menu icon) in a Toolbar / AppBarLayout programmatically ? I want to change the toolbar's colour scheme for a single fragment in an activity. Setting the AppBarLayout 's background to a light colour (e.g. light gray with appBarLayout.setBackgroundResource(..); ) results in white icons and a white title which are barely visible. Its layout is as follows: <android.support.design.widget.AppBarLayout android:id="@+id/appbar" android:layout_width

问题 I have an activity with XML. Something like: <?xml version="1.0" encoding="utf-8"?> <android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/drawer_layout" android:layout_width="match_parent" android:layout_height="match_parent" tools:context=".MainActivity"> <android.support.design.widget.CoordinatorLayout android:id="@+id/coordinator"

问题 As images are always better than words, I present to you my current layout . The toolbar/tabs is in an activity.xml with a viewPager, and the recyclerView is inside a fragment within the viewPager. So you can swipe right/left to see other content. My issue is that I want the AppBarLayout to be binded in its scrolling behaviour to the recyclerView in the first fragment, but not to the other fragments. In the code below, I did this binding but it doesn't work because the recyclerView doesn't

问题 I am looking to add scroll support to more than just a single, scrollable, child view of CoordinatorLayout in conjunction with an AppBarLayout and CollapsingToolbarLayout . When scrolling the RecyclerView or the AppBarLayout (condensed code below), the app bar and its contents successfully scroll and collapse. However, when attempting to initiate a scroll event on the LinearLayout above the RecyclerView , nothing happens because the LinearLayout does not know to scroll or collapse the view.

问题 I'm quite confused since I need to use two OnClickListeners for two different needs. I have a Recyclerview which once any item of his, once pressed, needs to change and I've implemented that successfully using OnBindViewHolder.itemView.setOnClickListener Now, I want that very same click to update my BottomAppBar and for that, I added an interface to my ItemHolder class. The issue is that now I once I click, due to the interface (I guess) nothing happens. I know it might be a bit complicated
