KeyboardAvoidingView not Working Properly

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

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"
  }
});

WARNING

This appears to be only a partial solution, although it works initially, if the android phone is locked on the screen with the keyboard avoiding layout, when you unlock you end up with the extra padding above the keyboard again.

tl;dr

Remove android:windowSoftInputMode="adjustResize" from the AndroidManifest.xml

Before

...
<activity
  android:name=".MainActivity"
  android:label="@string/app_name"  
  android:configChanges="keyboard|keyboardHidden|orientation|screenSize"
  android:windowSoftInputMode="adjustResize"
  >
...

After

...
<activity
  android:name=".MainActivity"
  android:label="@string/app_name"  
  android:configChanges="keyboard|keyboardHidden|orientation|screenSize"
  >
...

Why

If I understand the issue correctly, I have been dealing with the same thing. By having android:windowSoftInputMode="adjustResize" in the manifest, the android system will try to do the same job as the KeyboardAvoidingView. This results in extra spacing being added above the keyboard on Android only.

If working on both platforms you are going to have to deal with this on iOS every time you are working with keyboard input, so best to remove the android specific behaviour by android:windowSoftInputMode="adjustResize" from the manifest and using the KeyboardAvoidingView every time.

Answer 2

<KeyboardAvoidingView styles={styles.container} behavior = 'padding'  enabled>
   <ScrollView>

        <View>
          ....
        </View>

   </ScrollView>
</KeyboardAvoidingView>

Answer 3

This is a known issue with KeyboardAvoidingView and Android. There are multiple ways to address this issue.

React Native documentation says:

Android may behave better when given no behavior prop at all, whereas iOS is the opposite.

So, if you are working only with Android you may remove behavior prop and it should work straight away. For best results add android:windowSoftInputMode="adjustResize" to your Manifest.

Alternatively you can give an offset value that works for you something like this: KeyboardAvoidingView keyboardVerticalOffset={-500} behavior="padding"

For ios do the same thing conditionally:

behavior= {(Platform.OS === 'ios')? "padding" : null}

keyboardVerticalOffset={Platform.select({ios: 0, android: 500})}

Answer 4

 <KeyboardAvoidingView style={styles.keyboardcontainer} behavior="padding"
       keyboardVerticalOffset={Platform.select({ios :120, android : 500})}
       enabled>

    <View  style={{flex: 1 }}>
        // Your Code 
    </View>

</KeyboardAvoidingView>

Answer 5

I think this is because the behavior props value, so I think adding this line in the keyboardavoidview will help

<KeyboardAvoidingView
    style = {{ flex: 1 }}
    behavior={Platform.OS === "ios" ? "padding" : null}>
</KeyboardAvoidingView>

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>
