How can we stop KeyboardAvoidingView in React Native from overlapping content?

I'm working on implementing a KeyboardAvoidingView section for a signup form. I've managed to adjust the keyboard properly on both iOS and Android, but instead of increasing the view's height and scrolling up, the KeyboardAvoidingView is reducing the height.

Here's how it looks on Android:

Before keyboard adjustment:

After keyboard adjustment:

This is the component code:

<KeyboardAvoidingView keyboardVerticalOffset={20} behavior={Platform.OS === 'ios' ? 'padding' : null} style={mainWithFooter.container}>
  <View style={mainWithFooter.main}>
    <Text style={material.display1}>Create Your Account</Text>
  </View>
  <View style={mainWithFooter.footer}>
    <Input
      placeholder='First name'
      onChangeText={t => updateSignupForm('firstName', t)}
    />
    <Input
      placeholder='Last name'
      onChangeText={t => updateSignupForm('lastName', t)}
    />
    <Input
      placeholder='Email'
      keyboardType='email-address'
      autoCapitalize='none'
      onChangeText={t => updateSignupForm('email', t)}
    />
    <Input
      placeholder='Password'
      secureTextEntry
      onChangeText={t => updateSignupForm('password', t)}
    />
    <Button
      text='Create Account'
      onPress={signup}
      primary
      disabled={!signupFormIsValid}
      block
    />
  </View>
</KeyboardAvoidingView>

And here are the styles:

export default StyleSheet.create({
  container: {
    display: 'flex',
    flex: 1,
    backgroundColor: '#fff',
    alignItems: 'center',
    justifyContent: 'center',
    padding: 30,
    minHeight: '100%',
  },
  main: {
    flex: 1,
    display: 'flex',
    alignItems: 'center',
    justifyContent: 'center',
    marginBottom: 20,
  },
  footer: {
    width: '100%',
    flex: 0,
  },
})

Any suggestions on how to prevent content overlap?

Answer №1

Encountering the same issue led me to come up with a solution. I enclosed the children of KeyboardAvoidingView within a View element and then specified the minHeight of that element using Dimensions.get('window').height. Check out the revised example below:

<KeyboardAvoidingView keyboardVerticalOffset={20} behavior={Platform.OS === 'ios' ? 'padding' : null} style={mainWithFooter.container}>
    <View style={mainWithFooter.wrapper}> ** <-- wrapper here. **
      <View style={mainWithFooter.main}>
        <Text style={material.display1}>Create Your Account</Text>
      </View>
      <View style={mainWithFooter.footer}>
        <Input
          placeholder='First name'
          onChangeText={t => updateSignupForm('firstName', t)}
        />
       ...
      </View>
    </View>
  </KeyboardAvoidingView>

Next, define the style settings as follows:

const windowHeight: Dimensions.get('window').height;

export default StyleSheet.create({
  wrapper: {
    minHeight: windowHeight,
  },
    ...
});

You may also need to include any essential styles like flex to the wrapper.

One possible solution is to modify flex:1 to flexGrow:1.
