LinearLayout with dynamic height causing layout issues on different screen sizes

android layout linear-layout scrollview xml

I've been working on this all day and I'm upgrading from an older version and I'm sure I'm missing something obvious here, but I'm experiencing layout issues when using a `LinearLayout` that contains multiple child views with dynamic heights..... The layout works perfectly on a Pixel 4 but looks completely off on a Galaxy S10. The children seem to overflow the parent and cause unexpected scrolling behavior in my app. Here’s a simplified version of my layout XML: ```xml <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="vertical"> <TextView android:id="@+id/titleTextView" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="Sample Title" android:textSize="20sp" /> <View android:id="@+id/separator" android:layout_width="match_parent" android:layout_height="1dp" android:background="#ccc" /> <ScrollView android:layout_width="match_parent" android:layout_height="wrap_content"> <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="vertical"> <!-- Dynamic content that can change height --> <TextView android:id="@+id/dynamicTextView" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Dynamic content here..." /> </LinearLayout> </ScrollView> </LinearLayout> ``` I've set `layout_height` for the main `LinearLayout` to `wrap_content`, but I still see that on larger screens, the dynamic content pushes everything out of the view. I've tried using `match_parent` for both the `ScrollView` and the main `LinearLayout`, but that leads to a completely different issue where the content doesn't scroll at all. I also verified that there's no extra padding or margins causing overflow. The issue seems to stem from how different devices render the `ScrollView` and its children. When I run the app, I get the following warning in the logcat: ``` Warning: ScrollView can only be used with one direct child ``` It seems like the nested `LinearLayout` inside the `ScrollView` might not be playing nicely. Has anyone else faced similar issues? How can I ensure consistent behavior across different devices without compromising on the layout structure? Any suggestions or fixes would be greatly appreciated! For context: I'm using Xml on Linux. What's the best practice here? Am I approaching this the right way? This issue appeared after updating to Xml 3.11.
