React Native TextInput 不在 ScrollView 中滚动

React Native TextInput not scroll in ScrollView

我写了这样的代码:

<View style={{flex:1}}>
    <ScrollView style={{flex:1, backgroundColor='#ffffff'}}>
        <TextInput style={styles.inputText} 
                   value={this.state.mail}
                   placeholder="Email"
                   onChangeText={(text)=>this.setState.(mail:text)}/>
        <TextInput style={styles.inputText} 
                   value={this.state.fName}
                   placeholder="First name"
                   onChangeText={(text)=>this.setState.(fName:text)}/>
        <TextInput style={styles.inputText} 
                   value={this.state.sName}
                   placeholder="Second name"
                   onChangeText={(text)=>this.setState.(sName:text)}/>
    </ScrollView>
</View>

但是当我在 TextInput 中拖动开始时不滚动! 我像这样拖动: enter image description here 但不滚动...

问题已解决。我只是将这个道具添加到 TextInput 组件:

multiline={true}
numberOfLines={1}
