是否有任何內置文本區域組件可用於react-native?我試圖實現這些:
https://github.com/buildo/react-autosize-textarea
https://github.com/andreypopp/react-textarea-autosize
但是出現錯誤“期望組件類得到對像對象”。 
就在這裡。它稱為TextInput,普通的TextInput組件支持多行。
只需將以下屬性分配給您的TextInput組件
多行= {true}
numberOfLines = {4}
最後,您應該具有以下內容:
 this.setState({text})}
值= {this.state.text} />
來源https://facebook.github.io/react-native/docs/textinput
|
我通過以下方式將TextInput組件包裝到View中來構建本機文本區域:



...
const styles = StyleSheet.create({
textAreaContainer:{
borderColor:COLORS.grey20,
borderWidth:1
內邊距:5
},
textArea:{
高度:150,
justifyContent:“靈活啟動”
}
})
|
如果要像文本區域一樣查看TextInput組件,則需要添加此內容

|
我正在使用此組件:
https://www.npmjs.com/package/react-native-autogrow-textinput
它會自動擴展文本增長。我使用autogrow-textinput作為其一部分創建了自己的可重用組件,該組件內部的外觀如下所示:

|
如果只使用本機組件,則選擇TextInput
正如“ funkysoul”所解釋的:
只需將以下屬性分配給您的TextInput組件
多行= {true} numberOfLines = {4}
如果您希望將此組件視為經典的textarea(大於嵌入式文本輸入),則通常需要添加height樣式屬性。請參見以下示例:

我添加了backgroundColor以便更好地了解高度角色。請不要在您的項目中使用它;)
