我为TextInput创建了通用类，并多次使用了它，但是它的事件句柄具有相同的方法。我想在将数据填充到textInput中之后处理数组数据。

              placeholder = 'Please enter emailID.'
              placeholderTextColor = 'black'
              autoCapitalize = "none"
              keyboardType = "email-address"
              onSubmitEditing ={Keyboard.dismiss}

我创建ScrollView了三个视图.而且我想绑定里面的拖动视图ScrollView,其余的没有拖放视图应该保持在外面ScrollView.怎么可能呢？

  Text,
  PanResponder,
  Animated,

  Dimensions,
  Platform,
  TouchableOpacity,
  ScrollView,
} from 'react-native';
import Carousel from 'react-native-snap-carousel';

  ios: 'Press Cmd+R to reload,\n' +
    'Cmd+D or shake for dev menu',
  android: 'Double tap R on your keyboard to reload,\n' +
    'Shake or press menu button for dev menu',
});
