描述

Description

When wrapping View children in a Text component, the views are displayed inline with the text on web platforms. However, on Android and iOS platforms, adjusting the line height of the parent Text component causes the View children to no longer be inline with the text.

Steps to reproduce
  1. Create a parent Text component.
  2. Wrap View children within the Text component.
  3. Note how the views are inline with the text on web platforms.
  4. Adjust the line height of the parent Text component.
  5. Observe that the views are no longer inline with the text on Android and iOS platforms.

export default function App() {
  return (
    <SafeAreaView style={styles.container}>
      <Text style={styles.text} >

      <View
        style={{
          borderRadius: 40,
          height: 50,
          paddingHorizontal: 32,
          backgroundColor: 'yellow'
        }}
      >
        <Text>Button Text</Text>
      </View>
    </Text>
    </SafeAreaView>
  );
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: 'center',
    backgroundColor: '#ecf0f1',
    padding: 8,
  },
 text: {
    fontSize: 17,
    lineHeight: 29
  },
});

调研方向

从链接的 Expo Snack 复现示例开始,在 Android、iOS 和 web 上比较指定 lineHeight 时 Text 和 View 的布局。在更改行为之前,确认平台特定的对齐差异,并确定相关的原生文本布局入口点;完成的标准是,换行后的 View 在受影响的平台上都能一致地保持 inline。
