问题 I want to simply change the color of the button, but i can't. I tried to change directly in the button, and pass a style to it. But neither of them worked. Here's my very simple code. export default class Dots extends Component { render() { return ( <Image style={styles.container} source={require('./background3.png')}> <Button title='play' style = {{color:'red'}}/> </Image> ); } } const styles = StyleSheet.create({ container: { flex:1, backgroundColor:'transparent', resizeMode:'cover',

问题 I am interested in using the AServiceManager_get/addService() APIs that are made available via the NDK implementation of binder, libbinder_ndk . The sources for this can be found here for 10.0.0r30 - API29, and in your AOSP tree at: $SDK/frameworks/native/libs/binder/ndk/ However, the libbinder_ndk.so bundled with the latest r21c NDK does not have all of these APIs exported. Many are, but the get/add services endpoints are not available. The libbinder_ndk.so for API29 can be found at: $NDK

问题 My Xamarion.iOS binding project has the links to all the required native video SDK libraries and native OS frameworks. I have set the required frameworks using Frameworks attribute. Other settings include SmartLink=true, ForceLoad=true, IsCxx=true, LinkerFlags="-lc++". It can be built into a C# DLL. In iOS project, the DLL is referenced and used. However there are native linking errors. MTOUCH: Error MT5210: Native linking failed, undefined symbol: std::string::_Rep::_M_destroy(std::allocator

问题 I know that there's support for AOT in Xamarin for Android. After the software became free, all of its features became free as well. I read around the documentation and I enabled AOT by modifying my project.csproj file, as follows: <AotAssemblies>True</AotAssemblies> After making sure that my project path doesn't contain spaces (breaks process), I ran a build and I got an APK with both managed .NET DLLs and native compiled libs. Sadly, the app seems to be using the .NET DLLs and completely

问题 I want to setup the initial scroll position of a ListView.builder, I want the list to start at the bottom 0.0 If I setup reverse on the listView of course I get the initial scroll position to be the desired one, but what I need is to have the last children on the bottom, is a chat app. This is the list builder, MessageItem() is the chat message ListView.builder( shrinkWrap: true, controller: _scrollController, itemCount: snapshot.data.documents.length, padding: EdgeInsets.all(10.0),

问题 I am writing an app in .NET Core that depends on native code using [DllImport] . I have the native compiled library artifacts for win-x64, win-x86, and linux-x64.
