TextInput onContentSizeChange returns incorrect layout size instead of content size on Android

[Traviskn]

Description

The onContentSizeChange prop of the TextInput component does not work on Android as it does on iOS. On Android it seems to be returning the layout height and width of the TextInput view, rather than the height and width of the text.

This same issue has been reported before in #25487 and #19696, but does not seem to have been fixed

Steps To Reproduce

Run the following code on both iOS and Android platforms, note the inconsistency in the logged values from `contentSize:

import React from 'react';

import { View, TextInput } from 'react-native';

export default class App extends React.Component {
  render() {
    return (
      <View style={{ flex: 1, marginTop: 40 }}>
        <TextInput
          defaultValue="test"
          onLayout={ e=> {
            console.warn("single line layout", e.nativeEvent.layout)
          }}
          style={{ width: 200, lineHeight: 30, backgroundColor: '#CCC' }}
          onContentSizeChange={ e=> {
            console.warn(e.nativeEvent.contentSize)
          }}
        />
        <TextInput
          defaultValue="test"
          onLayout={ e=> {
            console.warn(e.nativeEvent.layout)
          }}
          multiline
          style={{ width: 200, lineHeight: 30, backgroundColor: '#CCC' }}
          onContentSizeChange={ e=> {
            console.warn(e.nativeEvent.contentSize)
          }}
        />
      </View>
    )
  }
}

Expected Results

On iOS as you edit text on single or multiline TextInput you get the actual width of the characters entered. I would expect the same behavior on Android. Effectively this functionality is not actually implemented on Android at the moment.

I changing value not from onChangeText
My conthent height now: 59.5
But onContentSizeChange fires once with previous height: 43

it's wrong. onContentSizeChange should trigger with 59.5 😔

This is still still an issue! onContentSize returns the size of the textinput, not the text inside it on Android.

Guys, I found the solution. It's incredible unintuitive but try adding a backgroundColor to the input...

@FontSanguinetti could you give me a little more detail into how this is related to onContentSizeChange?

This issue is driving me nut. Trying to calculate it using StaticLayout I can't get the correct value..

[eeshankeni]

This is absolutely messing up my logic to increase the size of the text input as the user types. Wtf man why is react native on android such a pain
