I am trying to create a XML template such as the Google Play which implement the use of listview and scroll view as below
<custom scrollview>
<imageview>
<textview>
<static listview> //list of comment
<custom scrollview>
The page is scrollable, but when user touch the listview area, the page become unscrollable, is there a way to make the entire page scrollable with the static listview in it?

In my layout, I have two items; an ImageView and a ListView, the ImageView appears on top of the ListView in a LinearLayout. The ImageView displays a logo or a profile image while the ListView displays a list of personal / company info.
Now this is my problem, the ListView scrolls on it's own with the ImageView fixed at the top but I want the ImageView to scroll with the ListView so that it is not fixed statically on top.
How do I do this? Is this possible? And if yes can I see an example. Thanks. :)
Edit: I have considered removing the scroll from the ListView and simply just displaying the items without scroll then I can wrap both the ImageView and ListView inside a ScrollView. However I do not know if this is possible or how I can implement it.
Take NestedScrollView as you parent layout and add a LinearLayout as it's child and add your ImageView and listView as child to this linear layout .
<NestedScrollView>
<LinearLayout>
<ImageView/>
<ListView/>
</LinearLayout>
</NestedScrollView>
I have a (vertical) linear layout inside a scroll view. The linear layout houses a set of other layouts.
<ScrollView>
<LinearLayout>
<layout1></layout1>
<layout2></layout2>
<layout3></layout3>
<layout4></layout4>
<LinearLayout>
</ScrollView>
I would like to be notified when a certain child of the linear layout is in view and be able to scroll to a desired layout.
Is there any way to achieve that?
I have an Activity where there is a Linear Layout which occupies nearly half of the screen and below that I need to keep a listview which has hold any number of items. Now initially I was doing like this
<ScrollView>
<LinearLayout>
</LinearLayout>
<ListView>
</ListView>
</ScrollView>
But reading all the threads I think it is not really a good idea keeping listview inside Scrollview. Also I am facing a lot of issues like the height of the Listview is not proper.
So how do I keep the layout and listview inside the same activity without using ScrollView?
It is not recommended to include a scrolling View (ListView) inside a ScrollView. What you want to achieve can be done by adding a HeaderView which can be inflated from another XML.
LinearLayout ll = inflater.inflate(R.layout.my_layout, null);
listView.addHeaderView(ll);
I have a form with a number of EditView fields in it. The data for these fields are loaded from a database (in the onCreate() method). The last object on the screen should be a ListView that should show all related data records to the record being show. All the data is correctly loading, and the adapter for this seems to work ok. It loads the correct data, it formats the data correctly into the two-line layout specified by the .xml used by the adapter.
The problem is that the ListView on the screen is "shrunk" to show only one item, and adds a scrollbar if there's more items. I expected the ListView to expand in size to show all records, and the screen itself being scrollable (everything is wrapped inside a ScrollView).
So, the XML looks like this:
<ScrollView
android:layout_height="wrap_content"
android:id="#+id/ScrollView1">
<RelativeLayout
android:layout_height="wrap_content"
android:id="#+id/RelativeLayout1">
<EditView
android:id="#+id/EditView1>
</EditView>
<ListView
android:id="#+id/ListView1
android:layout_height="wrap_content"
android:layout_below="#id/EditView1>
android:divider="#b5b5b5"
android:dividerHeight="1dp" />
I then use a custom BaseAdapter to fill data into the ListView
listView = (ListView) findViewById(R.id.ListView1);
dbRecords = db.getAllRecordsByRecordId(recordId);
CBA_Records adapter = new CBA_Records(this, dbRecords);
listView.setAdapter(adapter);
This is all the same stuff that I've done before, except this is all wrapped inside the scrollview. The reason for this is that there might be more fields than will fit on a smaller screen (or horizontal screen), so the screen must be scrollable. And, the listview must also be there ...
Any suggestions?
A little more onto what invertigo said. ListView inside a ScrollView is not recommended.
Make your ListView the root, and set it's width and height to "match_parent". Put the other stuff that's above the ListView (the header) in a separate xml. Then inflate the new xml file for the header use the addHeaderView() method to add it as a header to the ListView (it looks like you want everything to scroll).
ListView is vertically scrolling automatically, so you now have two vertical scroll areas, which do you expect to consume the scroll event? Either set your ListView to a static height (not recommended), or design your layout so only the area you want to scroll (ie the ListView) has scrolling capabilities and remove the ScrollView. Also set your base layout, in this case the RelativeLayout, to height=match-parent, and ListView height=0dp weight=1 to prevent the ListView from being "shrunk".
Alternatively, take a look at this solution if you dont want the ListView scrolling independantly: android listview display all available items without scroll with static header
I have a quite complex View build-up, and as a part of that, I have a ListView inside a LinearLayout within a ScrollView (and quite a lot more components, but they do not matter in this issue).
Now the whole activity scrolls nicely as it should, but the ListView has a limited height, and when the Items inside it surpass the height, the disappear of my screen. I've tried to place the ListView inside it's own ScrollView, but this doesn't work. When I try to scroll on the ListView, the main ScrollView is selected and my screen scrolls instead of the ListView.
My question may sound easy, but I haven't been able to fix this... Is it possible to make the ListView scrollable aswell?
The relevant XML:
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout android:id="#+id/GlobalLayout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<ListView android:id="#+id/EndpointList"
android:choiceMode="multipleChoice"
android:layout_height="175dip"
android:layout_width="fill_parent" />
</LinearLayout>
</ScrollView>
Instead of ListView with other layouts inside ScrollView create one ListView with header and footer.
Add views that should be above ListView as a header:
addHeaderView(View v)
and that below as a footer:
addFooterView(View v)
Put everything what should be above ListView to header of ListView and the same with footer.
LayoutInflater inflater = LayoutInflater.from(this);
mTop = inflater.inflate(R.layout.view_top, null);
mBottom = inflater.inflate(R.layout.view_bottom, null);
list.addHeaderView(mTop);
list.addFooterView(mBottom);
// add header and footer before setting adapter
list.setAdapter(mAdapter);
In result you'll get one scrollable view.
Actually, the way that I have it set up is really working... Placing a ListView in a LinearLayout within a ScrollView. Just avoid that the ListView is the direct child of the ScrollView, and it will work out just fine...
Just be aware that if there aren't enough items in the ListView to fill it so it goes 'off screen', that it won't scroll (kind of logically though). Also note that when you have enough items to scroll through, you need to keep pressing on an item in the ListView to make it scroll, and half of the time, focus is given to the global scrollview in stead of the ListView... To avoid this (most of the time), keep pressing on the most top or most down item, depending on which way you want to scroll.This will optimize your chance to get focus on your ListView.
I've made a video that it is possible, am uploading it now to YouTube...
Video is http://www.youtube.com/watch?v=c53oIg_3lKY. The quality is kinda bad, but it proves my point.
Just for a global overview, I used the ScrollView to be able to scroll my entire activity, the LinearLayout for the Activity's layout, and the ListView to, well, make the list...
I would like to just note something for the video
The listview is working once every x touches not because you placed it inside a linearlayout but because you are touching the the divider...
the scrollview will then consider that the place you touched does not have children to dispatch the motionevent to... so it calls the super.dispatchTouchEvent which is in this case the View.dispatchTouchView hence the listview.onTouchEvent.
When you touch inside a row the scrollview which is really a viewgroup will send the dispatch to the children in your case the textview and never calls the one of the view so the listview do not scroll.
Hope my explanation was clear enough to point out why is it not working.
