我正在尝试使用带有 behavior="padding" 的 KeyboardAvoidingView.

I am trying to use the KeyboardAvoidingView with behavior="padding".

出于某种原因，当我尝试在 TextInput 中输入任何文本时，TextInput 下方有一个空格.附件是正在发生的事情以及代码的图片.有没有人知道这里发生了什么?

For some reason, when I'm trying to enter any text in TextInput, there's a space below the TextInput. Attached is a picture of what is happening as well as the code. Any chance anyone has any idea whats happening here?

  render() {
    return (

      <KeyboardAvoidingView  style={{ flex: 1}}  behavior="padding">
      < View
          style={{
            flex: 1,
           
          backgroundColor: "#FFFFFF",
         
        }}
      >
        
        <ScrollView
          contentContainerStyle={{ justifyContent: "flex-end", flex: 1 }}>
                <ChatInfo />
              </ScrollView>

        
          <View style={styles.container}>
          <TextInput
            style={styles.input}
            underlineColorAndroid="transparent"
            autoCapitalize="none"
            onChangeText={text => this.setState({ text: text })}
            value={this.state.text}
          />

          <TouchableOpacity
            style={styles.submitButton}
            onPress={this.submitName}
          >
            <Text style={styles.submitButtonText}> SEND </Text>
          </TouchableOpacity>
        </View>
       
      </ View>
      </KeyboardAvoidingView>
    );
  }
}

export default connect()(ChatScreen);

const styles = StyleSheet.create({
  input: {
    margin: 2,
    paddingLeft: 15,
    flex: 1,
    height: 40,
    padding: 10,
    fontSize: 14,
    fontWeight: "400"
  },

      container: {
        borderTopWidth: 1,
        minWidth: "100%",
        borderColor: "#cccccc",
        height: 44,
        flexDirection: "row",
        justifyContent: "space-between",
        backgroundColor: "#fff"
        
      },

  submitButtonText: {
    color: "#0a9ffc",
    fontSize: 14,
    fontWeight: "500"
  },

  submitButton: {
    backgroundColor: "#fff",
    padding: 10,
    margin: 2,
    height: 40,
    alignItems: "center",
    justifyContent: "center"
  }
});

推荐答案

如果您使用的是 react-navigation，这会受到 react-navigation 标题的影响.标题的高度在不同的手机屏幕上有所不同.所以你必须得到header的高度并传入keyboardVerticalOffset props.

If you are using react-navigation, this is affected by the header of the react-navigation. The height of the header is vary on different mobile screen. So you have to get the height of the header and pass into the keyboardVerticalOffset props.

import { Header } from 'react-navigation-stack';

<KeyboardAvoidingView
  keyboardVerticalOffset = {Header.HEIGHT + 20} // adjust the value here if you need more padding
  style = {{ flex: 1 }}
  behavior = "padding" >

  <ScrollView>
    <TextInput/>
    <TextInput/>
    <TextInput/>
    <TextInput/>
    <TextInput/>
    <TextInput/>
  </ScrollView> 

</KeyboardAvoidingView>
