Proposal

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

Android - Switch to Expesify classic - Next button has extra padding on 2nd screen of survey

What is the root cause of that problem?

The StyleUtils.getMaximumHeight(formMaxHeight) makes the form's height is shorter than normal, so the button is moved to top as well:

App/src/pages/settings/ExitSurvey/ExitSurveyResponsePage.tsx

Line 107 in 3b0f99e

style={[styles.flex1, styles.mh5, formTopMarginsStyle, StyleUtils.getMaximumHeight(formMaxHeight)]}

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

We should remove that style.

Proposal

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

Next button of 2nd screen of survey on Android has extra spacing below it compares to other platform.

What is the root cause of that problem?

On the 2nd screen of the survey page, we have a max height style to limit the form height.

App/src/pages/settings/ExitSurvey/ExitSurveyResponsePage.tsx

Line 107 in 420c2a1

style={[styles.flex1, styles.mh5, formTopMarginsStyle, StyleUtils.getMaximumHeight(formMaxHeight)]}

The max height value in Android has a wrong calculation that leads to the form not taking all available space. The form height is used to let the form input to expand based on the form height.

App/src/pages/settings/ExitSurvey/ExitSurveyResponsePage.tsx

Lines 73 to 81 in 420c2a1

	const formMaxHeight = Math.floor(
	windowHeight -
	keyboardHeight -
	safeAreaInsetsTop -
	// Minus the height of HeaderWithBackButton
	variables.contentHeaderHeight -
	// Minus the top margins on the form
	formTopMarginsStyle.marginTop,
	);

The form height gets the window height and then subtracts it from the inset top. However, the window height on Android doesn't take the inset top height into account, so subtracting it from the inset top will make it smaller. We face this similar issue in #14563 too.

Another issue I noticed is that on iOS, the input can overlap with the button.

This is because recently, we have a PR that adds another bottom space for the button, but we didn't include the calculation yet to the max input height calculation.

App/src/pages/settings/ExitSurvey/ExitSurveyResponsePage.tsx

Lines 82 to 93 in 420c2a1

	const responseInputMaxHeight = NumberUtils.roundDownToLargestMultiple(
	formMaxHeight -
	// Minus the height of the text component
	textStyle.lineHeight -
	// Minus the response input margins (multiplied by 2 to create the effect of margins on top and bottom).
	// marginBottom does not work in this case because the TextInput is in a ScrollView and will push the button beneath it out of view,
	// so it's maxHeight is what dictates space between it and the button.
	baseResponseInputContainerStyle.marginTop * 2 -
	// Minus the approximate size of a default button
	variables.componentSizeLarge -
	// Minus the vertical margins around the form button
	40,

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

Add StatusBar.currentHeight to window height. StatusBar.currentHeight doesn't exist on other platforms.

const formMaxHeight = Math.floor(
        windowHeight + (StatusBar.currentHeight ?? 0) -

OR

We can remove the formMaxHeight and the max height style and get the form height from the form onLayout.

const [formHeight, setFormHeight] = useState(0);
const responseInputMaxHeight = NumberUtils.roundDownToLargestMultiple(
    formHeight - ...
);

<FormProvider
    onLayout={e => setFormHeight(e.nativeEvent.layout.height)}

The onLayout will be used in FormWrapper > FormElement.

App/src/components/Form/FormWrapper.tsx

Lines 107 to 111 in 420c2a1

	<FormElement
	key={formID}
	ref={formContentRef}
	style={[style, safeAreaPaddingBottomStyle.paddingBottom ? safeAreaPaddingBottomStyle : styles.pb5]}
	>

But the initial value of formHeight is 0, so there could be some "blinking".

---

To fix the iOS issue, we need to include the bottom padding to responseInputMaxHeight.

const {top: safeAreaInsetsTop, bottom: safeAreaInsetsBottom} = useSafeAreaInsets();
const safePaddingBottomStyle = useSafePaddingBottomStyle();

const responseInputMaxHeight = NumberUtils.roundDownToLargestMultiple(
        formMaxHeight - safeAreaInsetsBottom - (safePaddingBottomStyle.paddingBottom ?? 0) - ...

@JmillsExpensify 6 days overdue. This is scarier than being forced to listen to Vogon poetry!
