问题
I have a complex xml file and I really need a ScrollView. Please Don't mind the Ids as I have changed them. The ScrollView here doesn't work.

It can be done, although you should not put a listview inside a scrollview but sometimes this is the easier way: https://stackoverflow.com/a/3495908/1117338

Answer from a Google employee that works in Android:
Do not use ListView inside ScrollView

Use Like this: THIS WORKED LIKE CHARM
Remove Linear layout. use relative layout and inside that place your two list view like this.
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/scrollojt"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:fillViewport="true">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<ListView
android:id="@+id/listView1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#f00"></ListView>
<ListView
android:id="@+id/listView2"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="@+id/listView1"
android:background="#0f0"></ListView>
</RelativeLayout>
</ScrollView>
add Utility.java
public class Utility {
public static void setListViewHeightBasedOnChildren(ListView listView) {
ListAdapter listAdapter = listView.getAdapter();
if (listAdapter == null) {
// pre-condition
return;
}
int totalHeight = 0;
int desiredWidth = MeasureSpec.makeMeasureSpec(listView.getWidth(), MeasureSpec.AT_MOST);
for (int i = 0; i < listAdapter.getCount(); i++) {
View listItem = listAdapter.getView(i, null, listView);
listItem.measure(desiredWidth, MeasureSpec.UNSPECIFIED);
totalHeight += listItem.getMeasuredHeight();
}
ViewGroup.LayoutParams params = listView.getLayoutParams();
params.height = totalHeight + (listView.getDividerHeight() * (listAdapter.getCount() - 1));
listView.setLayoutParams(params);
listView.requestLayout();
}
}
In your Activity:
lv1.setAdapter(adapter);
lv2.setAdapter(adapter);
Utility.setListViewHeightBasedOnChildren(lv1);
Utility.setListViewHeightBasedOnChildren(lv2);

ScrollView and ListView both use scrolling. So in my opinion they shouldn't be used together. Try using RelativeLayout or some other layout instead of ScrollView
回答5:
You can set it by engulfing ListView in a parent layout like an example below -
<?xml version="1.0" encoding="utf-8"?>
<androidx.core.widget.NestedScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<androidx.cardview.widget.CardView
android:id="@+id/cardBrand"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding="@dimen/fab_margin"
android:layout_below="@+id/cardRange"
app:cardElevation="3dp">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<TextView
android:id="@+id/brandTitle"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Brands"
android:layout_marginTop="@dimen/fab_margin"
android:layout_marginLeft="@dimen/fab_margin"
android:layout_marginRight="@dimen/fab_margin"
android:textAppearance="@style/TextAppearance.AppCompat.Small"
android:textColor="@color/md_black_1000"/>
<ListView
android:id="@+id/brandList"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="8dp"
android:layout_marginLeft="8dp"
android:layout_marginRight="8dp"
android:layout_marginBottom="@dimen/fab_margin" />
</LinearLayout>
</androidx.cardview.widget.CardView>
<Space
android:layout_width="match_parent"
android:layout_height="6dp" />
<androidx.cardview.widget.CardView
android:id="@+id/cardRating"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding="@dimen/fab_margin"
android:layout_below="@+id/cardBrand"
app:cardElevation="3dp">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Ratings"
android:layout_marginTop="@dimen/fab_margin"
android:layout_marginLeft="@dimen/fab_margin"
android:layout_marginRight="@dimen/fab_margin"
android:textAppearance="@style/TextAppearance.AppCompat.Small"
android:textColor="@color/md_black_1000"/>
<ListView
android:id="@+id/ratingList"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="8dp"
android:layout_marginLeft="8dp"
android:layout_marginRight="8dp"
android:layout_marginBottom="@dimen/fab_margin" />
</LinearLayout>
</androidx.cardview.widget.CardView>
<Space
android:layout_width="match_parent"
android:layout_height="6dp" />
</LinearLayout>
</androidx.core.widget.NestedScrollView>
And, after the listview is populated -
eachitemSize = 180;
cardBrand.setLayoutParams(new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, eachitemSize * brandsAdapter.getCount()));
cardRating.setLayoutParams(new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, eachitemSize * ratingAdapter.getCount()));
What we did above is, we set the ScrollView height to match_parent. And after the ListView is populated we defined each parent layout of ListView to its ListView item count. And, remember to change the value of eachitemSize according to your each cell size.
Another thing to care about is after the LayoutParams is assigned its margin becomes invalid due to the new LayoutParams. So, use <Space/> instead of margin like the example above.
Hope it helps!!
