Fix calculating keyboard height #5851

maciekstosio · 2024-03-29T10:43:07Z

Summary

Should fix: #5811

Keyboard height seems to be improperly calculated. Based on my investigation it seems that WindowInsetsCompat.Type.ime() includes height of the keyboard + bottom navigation. What Reanimated does currently is checking if navigation bar is visible (KeyCharacterMap.deviceHasKey(KeyEvent.KEYCODE_HOME);) and then subtracts the bottom inset int keyboardHeight = DiphasNavigationBar ? contentBottomInset - systemBarBottomInset : contentBottomInset;. But to my understanding hasNavigationBar is always true, thus when keyboard is hidden keyboard height becomes -contentBottomInset. So I changed the navigation height to be Math.max(0, keyboardHeightDip)

Additionally in WindowInsetsManager.java I applied default paddings and added padding bottom which should help correctly position element from the bottom.

Remarks

on older androids < 11, hidden status bar rolls back to adjustPan keyboard behavior
flag isStatusBarTranslucentAndroid doesn't seems to do anything when screen has native header (headerShown: true)

Examples before vs after

Adding useAnimatedKeyboard breaks the layout

Before	After
adding.useAnimatedKeyboard.Before.mov	adding.useAnimatedKeyboard.After.mov

After closing the keyboard there is unexpected gap (negative height)

Before	After
topSpace.Before.mov	topSpace.After.mov

When StatusBar is hidden keyboard nor working properly on Android 10 - not fixed but not a regression

Before	After
statusBar.Before.mov	statusBar.after.mov

Test plan

Example showing the problem

import React, { useEffect, useState } from 'react';
import Animated, {
  useAnimatedKeyboard,
  useAnimatedReaction,
  useAnimatedStyle,
} from 'react-native-reanimated';
import {
  Platform,
  StatusBar,
  StyleSheet,
  TextInput,
  View,
  Text,
  Button,
} from 'react-native';

export default function EmptyExample() {
  const [statusBarHidden, setStatusBarHidden] = useState(false);
  const keyboard = useAnimatedKeyboard();

  const animatedStyles = useAnimatedStyle(() => ({
    transform: [{ translateY: -keyboard.height.value }],
  }));

  useAnimatedReaction(
    () => {
      return keyboard.height.value;
    },
    (currentValue) => console.log(currentValue)
  );

  useEffect(() => {
    StatusBar.setHidden(statusBarHidden);
  }, [statusBarHidden]);

  return (
    <Animated.View
      style={[
        styles.container,
        animatedStyles,
        { justifyContent: 'flex-end', borderWidth: 5, borderColor: '#ff0' },
      ]}>
      <Button
        title="Toggle StatusBar"
        onPress={() => setStatusBarHidden((hidden) => !hidden)}
      />
      <Button
        title="Show Warning"
        onPress={() => console.warn('WARNING!!!!')}
      />
      <View
        style={[
          styles.center,
          {
            height: 200,
            backgroundColor: '#f0f',
            borderWidth: 5,
            borderColor: '#0ff',
          },
        ]}>
        <Text>{`Android ${Platform.constants['Release']}`}</Text>
        <TextInput placeholder="Test" />
      </View>
    </Animated.View>
  );
}

const styles = StyleSheet.create({
  container: { flex: 1 },
  center: { justifyContent: 'center', alignItems: 'center' },
});

We need this fix 🙏

Temp fix:

res/values/styles.xml:

    <style name="AppFullScreenTheme" parent="Theme.AppCompat.DayNight.NoActionBar">
        <item name="android:windowNoTitle">true</item>
        <item name="android:windowActionBar">true</item>
        <item name="android:windowFullscreen">false</item>
        <item name="android:windowContentOverlay">@null</item>
        <item name="android:windowIsTranslucent">true</item>
        <item name="android:windowTranslucentNavigation">true</item>
    </style>

AndroidManifest.xml:

<application
    android:theme="@style/AppFullScreenTheme"

Wrap app's content in SafeAreaView
Height for chat's container:

const containerStyle = useAnimatedStyle(() => ({
    height: contentHeightAnim.value - keyboard.height.value + safeAreaInsets.bottom + (keyboard.height.value > 0 ? safeAreaInsets.bottom : 0),
  }))

@maciekstosio

is your keyboard animations on ios looks smooth ? cause on ios they're verry choppy in our app with same code
(it's not related to your PR)

TomCorvus · 2024-04-09T13:07:20Z

It doesn't work on my repro.
In my case, the warning message shows now in safe area view but the status bar is not includes in the print zone.
https://github.com/TomCorvus/RNSAV
these captures are done from a Google Pixel 7 with Android 14.

@TomCorvus Hi, have you tried using isStatusBarTranslucentAndroid option set to true? I tried to describe better what it does in new docs #5866.

TomCorvus · 2024-04-09T13:28:50Z

This option fix the shift. Thanks @maciekstosio
Why do we need to set this option? It doesn't take the item in styles.xml or backgroundColor="transparent" prop from StatusBar react-native component?

@maciekstosio

Hi, I focused on android implementation. It would be great if you could create separate issue if you're having problems on iOS.

maciekstosio · 2024-04-09T13:39:50Z

@TomCorvus On Android, to listen to keyboard changes we use immersive mode. It expands root view to full screen and gives away the control over insets management, so we need to apply them ourselves:

When isStatusBarTranslucentAndroid is false we apply the top and bottom margins according to the insets.
When isStatusBarTranslucentAndroid is true we apply bottom padding according to the navigation inset and sets top margin to 0.

maciekstosio · 2024-04-11T09:30:50Z

@TomCorvus I don't think I fully answered your question, it looks that we can do it automatically, you can see it in #5889.

It was related to bad optimization of chat lib. Made PR there: FaridSafi/react-native-gifted-chat#2493
