反应本机 AwesomeAlert customView 抛出错误

Question

我正在使用 react-native-awesome-alerts 插件在我的屏幕上显示警报。我为警报创建了一个自定义视图，但它抛出了这个错误

Cannot add a child that doesn't have a YogaNode to a parent without a measure function! (Trying to add a 'RCTRawText [text: }]' to a 'RCTView')

我的代码是这样的：

_displayNotifyAlert(){
  if(this.state.notifyAlert == true){
    return (
      <AwesomeAlert
        show={true}
        title="Service Cancellation"
        message="Tell the shop why are you cancelling their services."
        messageStyle={{ textAlign: 'center' }}
        customView={this.renderCustomAlertView()}
        showCancelButton={true}
        showConfirmButton={true}
        cancelText="Cancel"
        confirmText="Cancel Service"
        confirmButtonColor={Colors.default}
        onCancelPressed={() => this._closeNotifyAlert()}
        onConfirmPressed={() => this._cancelServices()}
      />
    )
  }
}

renderCustomAlertView = () => (
  <View style={[ AppStyles.input ]}>
    <TextInput
      placeholder="Write your reason briefly."
      underlineColorAndroid="transparent"
      style={{ textAlignVertical: 'top', height: 100 }}
      numberOfLines={5}
      multiline={true}
      maxLength={200}
      onChangeText={(cancel_reason) => this.setState({cancel_reason})} />
    }
  </View>
)

如果我删除这一行 customView={this.renderCustomAlertView()}，错误就会消失。我没有看到我在 renderCustomAlertView 函数中输入的任何错误代码。所以我无法追查错误的原因。有没有人遇到过同样的问题？

Answer 1

我无法在您的 post 中发表评论，因为声誉不佳，所以我将其作为答案。根据我对本机反应的了解并根据您的代码，您在 renderCustomAlertView 中缺少 return。

所以你的代码必须类似于

   renderCustomAlertView = () => {
             return(
              <View style={[ AppStyles.input ]}>
                  <TextInput
                     placeholder="Write your reason briefly."
                     underlineColorAndroid="transparent"
                     style={{ textAlignVertical: 'top', height: 100 }}
                     numberOfLines={5}
                     multiline={true}
                     maxLength={200}
                     onChangeText={(cancel_reason) => this.setState({cancel_reason})} />
           </View>
     )
   }

Answer 2

您的 renderCustomAlertView 函数末尾多了一个“}”。将此函数更改为以下内容，它应该可以工作：

renderCustomAlertView = () => (
  <View style={[ AppStyles.input ]}>
    <TextInput
      placeholder="Write your reason briefly."
      underlineColorAndroid="transparent"
      style={{ textAlignVertical: 'top', height: 100 }}
      numberOfLines={5}
      multiline={true}
      maxLength={200}
      onChangeText={(cancel_reason) => this.setState({cancel_reason})} />
  </View>
)
