拜拜、爱过 提交于 2019-12-07 03:24:28
I have two tabbar : ListMusic | Favourite. When I add a song to favourite in tab ListMusic, how can I set listener for tab Favourite know that it need for reload to display new data. Thanks! You can set one prop state which will be set on each change of ListMusic and use that prop in Favourite as key in render() 's parent view component. So, whenever state changes it will re-render Favourite. Example: render() { const unconfirmedErrorMsgToken = this.props.unconfirmedErrorMsgToken; return ( <View key={this.state.ListMusicSuccess} > ... </View> ); } 来源: https://stackoverflow.com/questions

Adding multiple events to onPress function in React Native

拜拜、爱过 提交于 2019-12-07 01:35:29
问题 When I press the button, it supposed to navigate to another page and it also increase the view count. But I can't figure out anyway to implement them at the same time. This is my code: <Button onPress={Actions.ideaOnClick}> <Button onPress={() => this.setState({views: ++this.state.views})}> 回答1: yourFunction(){ Actions.ideaOnClick(); this.setState({views: ++this.state.views}); } <Button onPress={this.yourFunction.bind(this)}}> 回答2: Just create a function that does both things. No other way

Full Text Search in React-native

一笑奈何 提交于 2019-12-06 15:20:50
React native noob here , I wanna know if it's possible to use the FullTextSearch feature of sqlite in react, if so , tell me where i can learn more about it . Thanks ! Use Realm Database for React Native , Realm is an object-oriented database. OO model makes it 10x faster than SQLite and saves you from running tons of query which is a common thing for a typical SQL database and fuse.js may help you to search text. realm = new Realm({ schema: [StudentScheme] }) const mydata = realm.objects('Product_Info'); let filteredData = []; let keywords = search.split(" "); keywords.forEach((obj, index) =>

What is the purpose of FlatViewManager in react native android?

女生的网名这么多〃 提交于 2019-12-06 14:52:57
问题 As far as my understanding, FlatViewManager would flat all its children and itself as a single view called FlatViewGroup. But then I found RCTTextManager return RCTText as its shadow nodes and RCTText is not a virtual node. So RCTTextManager will return FlatViewGroup as its viewInstance? And will there be view hierarchy in FlatViewGroup? I am not sure what the meaning of flat is. 回答1: Your understanding is correct, but there is something you are missing. FlatViewGroup doesn't do or draw

React native Async Storage Limit on Android

会有一股神秘感。 提交于 2019-12-06 10:48:42
I'm developing a React Native app which will easily exceed the 6mb limit. According to this , I should be able to use the method setMaximumSize, however I'm not sure of where or how I should invoke it in my project. A practical example would be welcome. EDIT: For anyone who needs this in the future here's how you do it: // MainApplication.getPackages() long size = 50L * 1024L * 1024L; // 50 MB com.facebook.react.modules.storage.ReactDatabaseSupplier.getInstance(getApplicationContext()).setMaximumSize(size); 来源: https://stackoverflow.com/questions/38991073/react-native-async-storage-limit-on

问题 I want to add more components after clicking on the button. Can you share code or an idea so that I can implement? As the image shows, every time when user click on the add button, one row / component will be added. 回答1: It's where state shining of, for example: constructor(props) { super(props); this._handleAddButton = this._handleAddButton.bind(this); this.state = { /* initial your state. without any added component */ data: [] } } _handleAddButton() { let newly_added_data = { title: 'new
