React Native Make View "Hug" the Top of the Keyboard
Custom hook:
import { useRef, useEffect } from 'react';
import { Animated, Keyboard, KeyboardEvent } from 'react-native';
export const useKeyboardHeight = () => {
const keyboardHeight = useRef(new Animated.Value(0)).current;
useEffect(() => {
const keyboardWillShow = (e: KeyboardEvent) => {
Animated.timing(keyboardHeight, {
duration: e.duration,
toValue: e.endCoordinates.height,
useNativeDriver: true,
}).start();
};
const keyboardWillHide = (e: KeyboardEvent) => {
Animated.timing(keyboardHeight, {
duration: e.duration,
toValue: 0,
useNativeDriver: true,
}).start();
};
const keyboardWillShowSub = Keyboard.addListener(
'keyboardWillShow',
keyboardWillShow
);
const keyboardWillHideSub = Keyboard.addListener(
'keyboardWillHide',
keyboardWillHide
);
return () => {
keyboardWillHideSub.remove();
keyboardWillShowSub.remove();
};
}, [keyboardHeight]);
return keyboardHeight;
};
Using Functional Component. This works for both iOS and Android
useEffect(() => {
const keyboardVisibleListener = Keyboard.addListener(
Platform.OS === "ios" ? "keyboardWillShow" : "keyboardDidShow",
handleKeyboardVisible
);
const keyboardHiddenListener = Keyboard.addListener(
Platform.OS === "ios" ? "keyboardWillHide" : "keyboardDidHide",
handleKeyboardHidden
);
return () => {
keyboardHiddenListener.remove();
keyboardVisibleListener.remove();
};}, []);
const handleKeyboardVisible = (event) => {
Animated.timing(paddingInput, {
duration: event.duration,
toValue: 60,
useNativeDriver: false,
});};
const handleKeyboardHidden = (event: any) => {
Animated.timing(paddingInput, {
duration: event.duration,
toValue: 0,
useNativeDriver: false,
});};
Few days ago I have the same problem (although I have a complex view with TextInput as a child) and wanted not only the TextInput to be focused but the whole view to be "attached" to the keyboard. What's finally is working for me is the following code:
constructor(props) {
super(props);
this.paddingInput = new Animated.Value(0);
}
componentWillMount() {
this.keyboardWillShowSub = Keyboard.addListener('keyboardWillShow', this.keyboardWillShow);
this.keyboardWillHideSub = Keyboard.addListener('keyboardWillHide', this.keyboardWillHide);
}
componentWillUnmount() {
this.keyboardWillShowSub.remove();
this.keyboardWillHideSub.remove();
}
keyboardWillShow = (event) => {
Animated.timing(this.paddingInput, {
duration: event.duration,
toValue: 60,
}).start();
};
keyboardWillHide = (event) => {
Animated.timing(this.paddingInput, {
duration: event.duration,
toValue: 0,
}).start();
};
render() {
return (
<KeyboardAvoidingView behavior='padding' style={{ flex: 1 }}>
[...]
<Animated.View style={{ marginBottom: this.paddingInput }}>
<TextTranslateInput />
</Animated.View>
</KeyboardAvoidingView>
);
}
where [..] you have other views.
@jazzdle example works great! Thank you for that!
Just one addition - in keyboardWillShow
method, one can add event.endCoordinates.height
so paddingBottom is exact height as keyboard.
keyboardWillShow = (event) => {
Animated.timing(this.paddingInput, {
duration: event.duration,
toValue: event.endCoordinates.height,
}).start();
}
