Proposal

Please re-state the problem that we are trying to solve in this issue.

Android - Compose Box - Composer not expanded when adding emojis until reaching second line

What is the root cause of that problem?

We have set height: 0 here but currently the input height does not increase when adding emoji and reaching the second line. It is android's behavior

What changes do you think we should make in order to solve the problem?

1. Add new state in Composer component

   const [inputContentHeight, setInputContentHeight] = useState<number | undefined>();

2. Update above state in onContentSizeChange

   onContentSizeChange={(e) => {
   setInputContentHeight(e?.nativeEvent?.contentSize?.height)
   ....
   }

3. Update composerStyle to bellow

   const isAndroidNative = getPlatform() === CONST.PLATFORM.ANDROID
   const composerStyle = useMemo(() => StyleSheet.flatten([
   style, textContainsOnlyEmojis ? styles.onlyEmojisTextLineHeight : {},
   isAndroidNative ? {height: inputContentHeight} : undefined
   ]), [style, textContainsOnlyEmojis, styles, inputContentHeight]);

   What alternative solutions did you explore? (Optional)

Proposal

Please re-state the problem that we are trying to solve in this issue.

The height of live markdown input doesn't fit its content on Android if it contains emojis.

What is the root cause of that problem?

MarkdownEmojiSpan uses font size in DIP units.

AbsoluteSizeSpan(int size, boolean dip) Set the text size to size physical pixels, or to size device-independent pixels if dip is true.

However, the text height measurement treats the font size as if it’s in pixels, so the measured height doesn't match the actual height.

What changes do you think we should make in order to solve the problem?

Use pixels in MarkdownEmojiSpan, just like in MarkdownFontSizeSpan below.

@QichenZhu Your proposal doesn't work for me

[DylanDylann]

@shahinyan11 Could you please provide a test branch?

[QichenZhu]

@DylanDylann Sorry I didn’t clearly mention that both arguments in the constructor need to change. Here’s the code I tested with. Could you double check?

node_modules/@expensify/react-native-live-markdown/android/src/main/java/com/expensify/livemarkdown/spans/MarkdownEmojiSpan.java

package com.expensify.livemarkdown.spans;

import android.text.style.AbsoluteSizeSpan;

import com.facebook.react.uimanager.PixelUtil;

public class MarkdownEmojiSpan extends AbsoluteSizeSpan implements MarkdownSpan {
  public MarkdownEmojiSpan(float fontSize) {
    super((int) PixelUtil.toPixelFromDIP(fontSize), false);
  }
}
