[英]react native - On button press load the whole screen with parent component
我試圖在按下按鈕時從子組件加載我的父組件。 但這不是從btnPress
方法呈現父組件。 我沒有任何錯誤。
onButtonPress
<Button onPress={() => btnPress(parent_id, id)}>
<Icon name="arrow-forward" />
</Button>
btnPress功能
function btnPress(parent_id, id) {
const App = () => (
//I have tried this way but this didn't work. No any error, i can see log on console
<Container>
<Headerc headerText={'Fitness sdaf'} />
<ExerciseList pId={parent_id} mId={id} />
</Container>
);
console.log(id);
AppRegistry.registerComponent('weightTraining', () => App);
}
完整代碼(子組件)
import React from 'react';
import { Right, Body, Thumbnail, Container, ListItem, Text, Icon } from 'native-base';
import { AppRegistry
} from 'react-native';
import Headerc from './headerc';
import ExerciseList from './exerciseList';
import Button from './Button';
const ExerciseDetail = ({ exercise }) => {
const { menu_name, menu_icon, parent_id, id } = exercise;
function NumberDescriber() {
let description;
if (menu_icon === 'noimg.jpg') {
description = `http://www.xxxxxx.com/uploads/icons/${menu_icon}`;
} else if (menu_icon === 'noimg.jpg') {
description = menu_icon;
} else {
description = `http://www.xxxxx.com/uploads/icons/${menu_icon}`;
}
return description;
}
function btnPress(parent_id, id) {
const App = () => (
<Container>
<Headerc headerText={'Fitness sdaf'} />
<ExerciseList pId={parent_id} mId={id} />
</Container>
);
console.log('-------------------------------');
console.log(id);
console.log('+++++++++++++++++++++++++++');
AppRegistry.registerComponent('weightTraining', () => App);
}
return (
<ListItem>
<Thumbnail square size={80} source={{ uri: NumberDescriber() }} />
<Body>
<Text>{menu_name}</Text>
<Text note> {menu_name} exercise lists</Text>
</Body>
<Right>
<Button onPress={() => btnPress(parent_id, id)}>
<Icon name="arrow-forward" />
</Button>
</Right>
</ListItem>
);
};
export default ExerciseDetail;
如果您需要更多信息,請告訴我。
我不建議這樣做,它看起來完全是反模式的,而不是。 最好嘗試導航或創建這樣的模式
在index.js或index.android.js或index.ios.js中
import App from './App' //your app level file
AppRegistry.registerComponent('weightTraining', () => App);
現在在您的應用js文件中
export default App class extends React.Component{
constructor(props){
super(props);
this.state ={
component1:false,
component2:true,
}
}
btnPressed =()=>{
//handle state update logic here
}
render(){
if(this.state.component1) return <Component1/>
return <Component2/>
}
}
****不是最好的解決方案,隨便玩吧,您會得到最好的
