问题 I followed this StackOverflow post's instructions and managed to get the ActionBarDrawerToggle and its animation working. However, no navigation drawer slides out. Why is that? activity_main.xml: <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" xmlns:app="http://schemas.android.com/apk/res-auto" android:id="@+id/container" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation=

问题 I'm currently using the usually amazing appcompat-v7 library in my application and I'm trying to tint my CheckBoxes without changing the Icon-Colors in the Toolbar (like the back arrow or those three dots). Following how it looks currently - as you can see not only the CheckBox is tinted pink, the back-arrow / three-dots are also tinted pink. My code: Layout <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height=

问题 I tried changing the color of all my RaisedButtons from the themeData but it refused to work. All other properties such as fontSize and fontWeight changed successfully. The color of the text only changes from black to white when the brightness property of themeData is changed to Brightness.dark . I there a way I can solve this issue? What could I be doing wrong? Here is my sample code: return new MaterialApp( title: 'Flutter Demo', theme: new ThemeData( primaryColor: Color(0XFF212845),

问题 I have extended the well-known Google Navigation Drawer Example by adding Toolbar and right-side Drawer in a simple test project at GitHub: How to add a "burger" button to the Toolbar - which would open the right Drawer (currently you can only swipe it with a finger)? The "burger" button for the left Drawer is already there and works well (probably added by ActionBarDrawerToggle?) Here is my current activity_main.xml: <android.support.v4.widget.DrawerLayout xmlns:android="http://schemas

问题 I have 4 tabs on the bottom of the screen and for the last tab I want to set a user profile image if he has it. I tried everything. Only the icon set from a drawable works fine. Every other case is a disaster. I found out that if I remove icon tint and icon mode on android versions above 26 it works fine. For versions under it, it's not working. Here is the code. Maybe somebody will have some ideas about how to help. This is how i set the icon from a drawable. This imageView is just a test to

问题 I'm probably missing something obvious here, but my BottomSheet only takes up the bottom half the screen, even though the widgets in it take up more space. So now there is scrolling behavior inside the BottomSheet. I'd like to be able to increase the BottomSheet so that the user doesn't have to scroll as much. I also want to add a borderRadius to the top of my BottomSheet, so that it looks more "modal"-y or "tab"-like. Code: void _showBottomSheet(BuildContext context) { showModalBottomSheet

问题 I am trying to figure out how to create a breadcrumb in my android app's (material design) toolbar. This can be seen in the latest Dropbox android application, in which the breadcrumb is used to display the navigation of the files. I have also found an image (which I took from another similar question), which can be seen here: Can you guide me on how I can do this? 回答1: I don't think you need a library. If you create a View (maybe a FrameLayout) and then you set it as background the same
