android android-layout linear-layout Java

I've searched everywhere and can't find a clear answer. Could someone explain I'm reviewing some code and I'm working on a project and hit a roadblock. I can't seem to get I'm working with an scenario where a nested `LinearLayout` is not properly adjusting its height when the content inside it is dynamically updated. I'm using Android API 31 and the layout is structured as follows: ```xml <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="vertical"> <TextView android:id="@+id/titleText" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="Initial Title" /> <LinearLayout android:id="@+id/dynamicContentLayout" android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="vertical" /> </LinearLayout> ``` In my activity, I am adding views to the `dynamicContentLayout` programmatically: ```java LinearLayout dynamicContentLayout = findViewById(R.id.dynamicContentLayout); for (int i = 0; i < 5; i++) { TextView textView = new TextView(this); textView.setText("Dynamic Text " + (i + 1)); dynamicContentLayout.addView(textView); } ``` However, even after adding the `TextView` elements, the height of the `dynamicContentLayout` does not change, and it remains at 0dp. I've tried calling `requestLayout()` and `invalidate()` after adding the views, but it doesn't help. The height of the outer `LinearLayout` also doesn't adjust accordingly, leading to the TextViews being cut off. I also ensured that the parent layout has a vertical orientation, and `match_parent` is used appropriately. I've tested this on physical devices and the emulator, both showing the same question. Any insights on how to resolve this scenario would be greatly appreciated! My team is using Java for this REST API. I've been using Java for about a year now. I'm working with Java in a Docker container on Windows 10. Could someone point me to the right documentation? For reference, this is a production REST API. Is there a simpler solution I'm overlooking?
