Trying to implement scrolling activity. ExpandableListView elements scroll, but the header that I connected, does not want to separately. Markup code: activity_main

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" android:id="@+id/activity_expandable_scroll_view" android:layout_width="match_parent" android:layout_height="match_parent" android:fillViewport="true"> <LinearLayout android:id="@+id/LinearLayout1" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical"> <RelativeLayout android:layout_width="match_parent" android:layout_height="wrap_content"> <TextView android:id="@+id/textView2" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignTop="@+id/textView" android:layout_marginStart="72dp" android:layout_toEndOf="@+id/textView" android:text="Инициативное поручение" /> <TextView android:id="@+id/textView3" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignStart="@+id/textView" android:layout_below="@+id/textView" android:layout_marginStart="20dp" android:layout_marginTop="22dp" android:text="Срок:22.12.2017" /> <ImageView android:id="@+id/imageView" android:layout_width="25dp" android:layout_height="25dp" android:layout_alignBottom="@+id/textView5" android:layout_alignStart="@+id/textView2" android:layout_marginStart="25dp" android:paddingRight="5dp" app:srcCompat="@mipmap/ic_launcher" /> <TextView android:id="@+id/textView4" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignStart="@+id/textView3" android:layout_below="@+id/textView3" android:layout_marginTop="15dp" android:text="Прошу принять Прошу принять Прошу принять Прошу принять" /> <TextView android:id="@+id/textView5" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignTop="@+id/textView3" android:layout_marginTop="10dp" android:layout_toEndOf="@+id/imageView" android:text="3" /> <TextView android:id="@+id/textView" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentStart="true" android:layout_alignParentTop="true" android:layout_marginStart="17dp" android:layout_marginTop="33dp" android:text="тест" /> </RelativeLayout> <ExpandableListView android:id="@+id/expListView" android:layout_width="wrap_content" android:layout_height="match_parent" android:layout_marginLeft="20dp" android:divider="@null" android:dividerHeight="-16dp" android:groupIndicator="@null" /> </LinearLayout>

    Found a solution:

      listView.setOnGroupClickListener(new ExpandableListView.OnGroupClickListener() { @Override public boolean onGroupClick(ExpandableListView parent, View v, int groupPosition, long id) { setListViewHeight(parent, groupPosition); return false; } }); } private void setListViewHeight(ExpandableListView listView, int group) { ExpandableListAdapter listAdapter = (ExpandableListAdapter) listView.getExpandableListAdapter(); int totalHeight = 0; int desiredWidth = View.MeasureSpec.makeMeasureSpec(listView.getWidth(), View.MeasureSpec.EXACTLY); for (int i = 0; i < listAdapter.getGroupCount(); i++) { View groupItem = listAdapter.getGroupView(i, false, null, listView); groupItem.measure(desiredWidth, View.MeasureSpec.UNSPECIFIED); totalHeight += groupItem.getMeasuredHeight(); if (((listView.isGroupExpanded(i)) && (i != group)) || ((!listView.isGroupExpanded(i)) && (i == group))) { for (int j = 0; j < listAdapter.getChildrenCount(i); j++) { View listItem = listAdapter.getChildView(i, j, false, null, listView); listItem.measure(desiredWidth, View.MeasureSpec.UNSPECIFIED); totalHeight += listItem.getMeasuredHeight(); } } } ViewGroup.LayoutParams params = listView.getLayoutParams(); int height = totalHeight + (listView.getDividerHeight() * (listAdapter.getGroupCount() - 1)); if (height < 10) height = 200; params.height = height; listView.setLayoutParams(params); listView.requestLayout(); }
