react-native-keyboard-aware-scroll-view-dgjoy v0.3.1

react-native-keyboard-aware-scroll-view

A ScrollView component that handles keyboard appearance and automatically scrolls to focused TextInput.

Supported versions

• v0.2.0 requires RN>=0.32.0.
• v0.1.2 requires RN>=0.27.2 but you should use 0.2.0 in order to make it work with multiple scroll views.
• v0.0.7 requires react-native>=0.25.0.
• Use v0.0.6 for older RN versions.

Installation

Installation can be done through npm:

npm i react-native-keyboard-aware-scroll-view --save

Usage

You can use the KeyboardAwareScrollView or the KeyboardAwareListView components. Both accept ScrollView and ListView default props and implements a custom KeyboardAwareMixin to handle keyboard appearance. The mixin is also available if you want to use it in any other component.

Import react-native-keyboard-aware-scroll-view and wrap your content inside it:

import { KeyboardAwareScrollView } from 'react-native-keyboard-aware-scroll-view'

<KeyboardAwareScrollView>
  <View>
    <TextInput />
  </View>
</KeyboardAwareScrollView>

Auto-scroll in TextInput fields

As of v0.1.0, the component auto scrolls to the focused TextInput 😎. For versions v0.0.7 and older you can do the following.

Programatically scroll to any TextInput

In order to scroll to any TextInput field, you can use the built-in method scrollToFocusedInput. Example:

_scrollToInput (reactNode: any) {
  // Add a 'scroll' ref to your ScrollView
  this.refs.scroll.scrollToFocusedInput(reactNode)
}

<KeyboardAwareScrollView ref='scroll'>
  <View>
    <TextInput onFocus={(event: Event) => {
      // `bind` the function if you're using ES6 classes
      this._scrollToInput(ReactNative.findNodeHandle(event.target))
    }/>
  </View>
</KeyboardAwareScrollView>

Programatically scroll to any position

There's another built-in function that lets you programatically scroll to any position of the scroll view:

this.refs.scroll.scrollToPosition(0, 0, true)

Register to keyboard events

You can register to ScrollViewResponder events onKeyboardWillShow and onKeyboardWillHide:

<KeyboardAwareScrollView
  onKeyboardWillShow={(frames: Object) => {
    console.log('Keyboard event', frames)
  }}>
  <View>
    <TextInput />
  </View>
</KeyboardAwareScrollView>

Android Support

First, Android natively has this feature, you can easily enable it by setting windowSoftInputMode in AndroidManifest.xml. Check here.

But if you want to use feature like extraHeight, you need to enable Android Support with the following steps:

• Make sure you are using react-native 0.46 or above.
• Set windowSoftInputMode to adjustPan in AndroidManifest.xml.
• Set enableOnAndroid property to true.

Android Suppor is not perfect, here is the support list:
