<RelativeLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="0.7"
android:padding="10dp">
<ScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<Button
android:layout_width="match_parent"
android:layout_height="40dp"
android:id="@+id/client_detail"
android:text="CLIENT INFORMATION"
android:textColor="@color/colorPrimaryDark"
android:background="@drawable/login_selector"/>
<RelativeLayout
android:id="@+id/rl1"
android:layout_width="match_parent"

android:layout_marginTop="10dp" />
</RelativeLayout>
</ScrollView>
</RelativeLayout>

You need to use ExpandableHeightListView.您需要使用 ExpandableHeightListView。
https://github.com/paolorotolo/ExpandableHeightListView https://github.com/paolorotolo/ExpandableHeightListView
when you use ListView
with ScrollView
, only one row of the ListView
will be visible, so you have to set the height of ListView pro-grammatically depending on the elements inside ListView
.You can make a function like this-当您将
ListView
与ScrollView
一起使用时,只有一行ListView
可见,因此您必须根据ListView
的元素以编程方式设置 ListView 的高度。您可以制作这样的功能 -
public static void setListViewHeightBasedOnChildren(ListView listView) {
ListAdapter listAdapter = listView.getAdapter();
if (listAdapter == null) {
return;
}
int desiredWidth = View.MeasureSpec.makeMeasureSpec(listView.getWidth(), View.MeasureSpec.AT_MOST);
int totalHeight = 0;
View view = null;
for (int i = 0; i < listAdapter.getCount(); i++) {
view = listAdapter.getView(i, view, listView);
if (i == 0) {
view.setLayoutParams(new ViewGroup.LayoutParams(desiredWidth, ViewGroup.LayoutParams.WRAP_CONTENT));
}
view.measure(desiredWidth, View.MeasureSpec.UNSPECIFIED);
totalHeight += view.getMeasuredHeight();
}
ViewGroup.LayoutParams params = listView.getLayoutParams();
params.height = totalHeight + (listView.getDividerHeight() * (listAdapter.getCount() - 1));
listView.setLayoutParams(params);
listView.requestLayout();
}
Then you use this method on the listview created-然后你在创建的列表视图上使用这个方法 -
HourAdapter adapter1=new HourAdapter(getActivity(),day,start,end,x);
listview.setAdapter(adapter1);
setListViewHeightBasedOnChildren(listview);
It works even if the rows of the ListView
have variable height即使
ListView
的行具有可变高度,它也能工作
