KeyboardAvoidingView在从虚拟键盘选择表情符号时覆盖TextInput UI。
这是一个示例代码，KeyboardAvoidingView在这种情况下可以很好地从虚拟键盘输入文本。但是，在切换到虚拟键盘中的表情符号选择器时，自动调整的padding | height没有效果，TextInput被虚拟键盘覆盖。

import React from 'react';
import { View, KeyboardAvoidingView, TextInput, StyleSheet, Text,,TouchableWithoutFeedback, Keyboard } from 'react-native';

const KeyboardAvoidingComponent = () => {
  return (
    <KeyboardAvoidingView
      behavior={Platform.OS === "ios" ? "padding" : "height"}
      style={styles.container}
    >
      <TouchableWithoutFeedback onPress={Keyboard.dismiss}>
        <View style={styles.inner}>
          <Text style={styles.header}>Keyboard Avoiding View</Text>
          ...
          <FlatList 
          ...
          <TextInput placeholder="Username" style={styles.textInput} />
        </View>
      </TouchableWithoutFeedback>
    </KeyboardAvoidingView>
  );
};

const styles = StyleSheet.create({
  container: {
    flex: 1
  },
  inner: {
    padding: 24,
    flex: 1,
    justifyContent: "space-around"
  },
  header: {
    fontSize: 36,
    marginBottom: 50
  },
  textInput: {
    height: 40,
    borderColor: "#000000",
    borderBottomWidth: 1,
    marginBottom: 36
  },
});

export default KeyboardAvoidingComponent;
