Reactjs 即使flex:1,React本机文本输入字段也不全宽
我正在formik上制作一个表单,并希望它具有全屏幕宽度。我试过flex:1,改变flex方向,改变填充。当文本宽度超过输入字段时,它会展开以适应它。我不想设置宽度,因为我希望它随手机屏幕的宽度而改变。这是一张它现在的样子 以下是我的样式代码:Reactjs 即使flex:1,React本机文本输入字段也不全宽,reactjs,react-native,react-native-flexbox,react-styleguidist,Reactjs,React Native,React Native Flexbox,React Styleguidist,我正在formik上制作一个表单,并希望它具有全屏幕宽度。我试过flex:1,改变flex方向,改变填充。当文本宽度超过输入字段时,它会展开以适应它。我不想设置宽度,因为我希望它随手机屏幕的宽度而改变。这是一张它现在的样子 以下是我的样式代码: const styles = StyleSheet.create({ input: { padding: 10, fontSize: 18, borderRadius: 6, flex: 1, borderBo

您需要为包装器的文本区域留出一些宽度
你将给出宽度
import { Dimensions } from 'react-native';
const windowWidth = Dimensions.get('window').width;
width: windowWidth;
只要用一个文本输入就可以了
return (
<View style={styles.container}>
<KeyboardAvoidingView
behavior={Platform.OS === "ios" ? "padding" : null}
style={{ flex: 1, width: "100%" }}
>
<ScrollView style={styles.inner}>
<TextInput
style={styles.input}
placeholder="Postal Code"
value={"fdf"}
/>
</ScrollView>
</KeyboardAvoidingView>
</View>
);
返回(
);
它肯定会工作:)需要完整的渲染组件,textinput的位置取决于父用户界面。。。编辑并粘贴您的整个组件更新,我认为它会太长,但我现在有它
