I have a listView which takes data from a rest API server and displays it. I need to add a textView on the side of it describing the type of data.
The right half of the screen has the listView and the left half has the textView.
The problem arises when the textView moves to accommodate the different screen sizes. I need the textView to be fixed and to be shown in conjunction with listView, and be in a straight line with the listView, regardless of the screen size. Cheers.
Edit: Image added of the sketch
It sounds like a ListView is not what you want to use. You cannot align Views with the children of a ListView. You would need to either put the TextViews within the ListView's children or not use a ListView.
The simplest way to do this would be a vertical LinearLayout containing many horizontal LinearLayouts.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<TextView
android:layout_width="100dp"
android:layout_height="match_parent"/>
<Item that was in the ListView />
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<TextView
android:layout_width="100dp"
android:layout_height="match_parent"/>
<Item that was in the ListView />
</LinearLayout>
...
</LinearLayout>
The ListView is really for scrolling and when you don't know how many items there will be.
Perhaps you already have an adapter in which you are handling the creation of the items and that's why you are using a ListView. You can still create the LinearLayout's children programmatically by inflating each item individually and adding it to the container view.
Original Answer:
You probably want the TextViews to scroll with the ListView as well. So I would think you should use one ListView, then add the TextView to the left side of the ListView item.
You should use weightSum,
Here is an example.
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:weightSum="2"
android:orientation="horizontal">
<ListView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"/>
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="Hello World"/>
</LinearLayout>
I have a layout which is divided in other two layouts: a LinearLayout for the "Header" and a RelativeLayout for the "Content".
In the content layout I have a ListView that needs to grown when the user scrolls, and hide this same ListView behind the header layout.
Basically, I need something like this:
What would be the best aproach to do something like this? This is my layout.xml right now:
<LinearLayout
android:id="#+id/layout_full"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#drawable/background_base"
android:fitsSystemWindows="true"
android:orientation="vertical"
android:weightSum="1"
tools:context=".app.Main">
<!-- Header -->
<LinearLayout
android:id="#+id/header"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight=".55"
android:background="#drawable/background_header_small"
android:gravity="center_horizontal">
</LinearLayout>
<!-- Content -->
<RelativeLayout
android:id="#+id/content"
android:layout_width="match_parent"
android:layout_height="fill_parent"
android:layout_weight=".45">
<ListView
android:id="#+id/listview_full"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_above="#+id/text_add"
android:layout_alignEnd="#+id/text_add"
android:layout_alignStart="#+id/text_add"
android:divider="#null"
android:dividerHeight="0dp"
android:showDividers="none"
android:layout_marginBottom="10dp"
android:footerDividersEnabled="false"
android:layout_alignParentTop="true"
android:layout_marginTop="20dp" />
</RelativeLayout>
</LinearLayout>
Can I somehow remove the elevator component of the ListView, and scroll the ListView instead of the Items inside the ListView?
Apologies, I can't comment yet. But you probably want to use the CoordinatorLayout as your parent, instead of the LinearLayout you're using now. From there you have two options: the hackier way is to use a transparent CollapsingToolbar that is placed underneath the header, the other way is to create your own Behavior that will increase the high/top of the List.
This is under the assumption that the ListView will continue to scroll as normal when the the top of it reaches the top of the screen?
I can throw something together when I get home if this seems like it's on the right track.
I have a ListView over a LinearLayout. There are clickable elements in the LinearLayout and since the ListView is transparent I can see those elements, and would like to be able to click on them, but even though the ListView looks transparent, it behaves as a barrier and doesn't let me click on the elements.
Is there a way I can click through the ListView?
If I change the ListView layout_height to wrap_content, it behaves as I want, but I need it to start with a certain height, so the items will stack at the bottom with android:stackFromBottom="true".
This is an example of how the code looks like:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
(Clickable elements)
</LinearLayout>
<ListView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#android:color/transparent"
android:transcriptMode="normal"
android:layout_marginTop="100dp"
android:layout_marginBottom="361dp"
android:stackFromBottom="true"
android:listSelector="#android:color/transparent"/>
</RelativeLayout>
Extend listview and override the onTouch() method and pass it down to the underlying views
I have a ListView that is being populated with a custom adapter. I have a pretty basic layout for each row of the the ListView (not even sure if this is applicable to my question):
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
style="#style/BaseStyle"
android:orientation="vertical"
android:paddingLeft="5dip"
android:paddingRight="5dip"
android:paddingTop="8dip"
android:paddingBottom="8dip"
>
<TextView
android:id="#+id/text"
style="#style/BaseStyle.Title"
/>
</RelativeLayout>
I'd like to overlay a single TextView at the bottom of the ListView, but not entirely sure how as working with Android layouts can be an exercise in futility. :)
Wrap your main layout with a FrameLayout and put the view that you want to be in overlay as last child.
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/home_container"
android:layout_height="match_parent"
android:layout_width="match_parent">
...
your ListView
...
your text view (it is gonna be on top of your layout)
</FrameLayout>
From your description I am not sure that this is what you are looking for, you should give some more info in your question, let me know.
If instead you are just talking about the TextView inside each list item then you just need to specifiy the alignment in your text view:
android:layout_alignParentBottom="true"
I tried to use marginBottom on the listView to make space between listView Item, but still the items are attached together.
Is it even possible? If yes, is there a specific way to do it?
My code is below
<LinearLayout
android:id="#+id/alarm_occurences"
android:layout_width="fill_parent"
android:orientation="vertical"
android:layout_height="fill_parent"
android:background="#EEEEFF"
xmlns:android="http://schemas.android.com/apk/res/android">
<ListView
android:id="#+id/occurences"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>
</LinearLayout>
My custom List item:
<com.android.alarm.listItems.AlarmListItem
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#drawable/alarm_item_background"
android:layout_marginBottom="10dp"
>
<CheckedTextView
android:id="#android:id/text1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center_vertical"
android:checkMark="?android:attr/listChoiceIndicatorMultiple"
android:textSize="20sp"
android:textStyle="bold"
android:typeface="serif"
android:padding="10dp"
/>
</com.android.alarm.listItems.AlarmListItem>
How can I make spacing between list items in this case?
#Asahi pretty much hit the nail on the head, but I just wanted to add a bit of XML for anyone maybe floating in here later via google:
<ListView android:id="#+id/MyListView"
android:layout_height="match_parent"
android:layout_width="match_parent"
android:divider="#android:color/transparent"
android:dividerHeight="10.0sp"/>
For some reason, values such as "10", "10.0", and "10sp" all are rejected by Android for the dividerHeight value. It wants a floating point number and a unit, such as "10.0sp". As #Goofyahead notes, you can also use display-independent pixels for this value (ie, "10dp").
Perhaps divider or dividerHeight property of the ListView can solve your problem.
Although the solution by Nik Reiman DOES work, I found it not to be an optimal solution for what I wanted to do. Using the divider to set the margins had the problem that the divider will no longer be visible so you can not use it to show a clear boundary between your items. Also, it does not add more "clickable area" to each item thus if you want to make your items clickable and your items are thin, it will be very hard for anyone to click on an item as the height added by the divider is not part of an item.
Fortunately I found a better solution that allows you to both show dividers and allows you to adjust the height of each item using not margins but padding. Here is an example:
ListView
<ListView
android:id="#+id/listView"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>
ListItem
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="10dp"
android:paddingTop="10dp" >
<TextView
android:id="#+id/textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:text="Item"
android:textAppearance="?android:attr/textAppearanceSmall" />
</RelativeLayout>
You should wrap your ListView item (say your_listview_item) in some other layout e.g LinearLayout and add margin to your_listview_item:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<your_listview_item
android:id="#+id/list_item"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="5dp"
android:layout_marginBottom="5dp"
android:layout_marginLeft="5dp"
android:layout_marginRight="5dp"
...
...
/>
</LinearLayout>
This way you can also add space, if needed, on the right and left of the ListView item.
My solution to add more space but keep the horizontal line was to add divider.xml in the res/drawable folder and define line shape inside:
divider.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="line" >
<stroke
android:width="1px"
android:color="#color/nice_blue" />
</shape>
then in my list I reference my divider as follows:
<ListView
android:id="#+id/listViewScheduledReminders"
android:layout_width="match_parent"
android:layout_height="0dip"
android:layout_marginBottom="#dimen/mediumMargin"
android:layout_weight="1"
android:divider="#drawable/divider"
android:dividerHeight="16.0dp"
android:padding="#dimen/smallMargin" >
</ListView>
notice the android:dividerHeight="16.0dp" by increasing and decreasing this height I am basically adding more padding on top and bottom of the divider line.
I used this page for reference: http://developer.android.com/guide/topics/resources/drawable-resource.html#stroke-element
For my application, i have done this way
<ListView
android:id="#+id/staff_jobassigned_listview"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:divider="#null"
android:dividerHeight="10dp">
</ListView>
just set the divider to null and providing height to the divider did for me.
Example :
android:divider="#null"
or
android:divider="#android:color/transparent"
and this is result
If you want to show a divider with margins and without stretching it - use InsetDrawable (size must be in a format, about which said #Nik Reiman):
ListView:
<ListView
android:id="#+id/listView"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:cacheColorHint="#00000000"
android:divider="#drawable/separator_line"
android:dividerHeight="10.0px"/>
#drawable/separator_line:
<?xml version="1.0" encoding="utf-8"?>
<inset xmlns:android="http://schemas.android.com/apk/res/android"
android:insetLeft="5.0px"
android:insetRight="5.0px"
android:insetTop="8.0px"
android:insetBottom="8.0px">
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<gradient
android:startColor="#color/colorStart"
android:centerColor="#color/colorCenter"
android:endColor="#color/colorEnd"
android:type="linear"
android:angle="0">
</gradient>
</shape>
</inset>
You can use:
android:divider="#null"
android:dividerHeight="3dp"
example:
<ListView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="#+id/listView" android:layout_gravity="center_horizontal"
android:dividerHeight="3dp"
android:divider="#null" android:clickable="false"/>
I realize that an answer was already been selected, but I just wanted to share what ended up working for me when I ran into this issue.
I had a listView where each entry in the listView was defined by its own layout, similar to what Sammy posted in his question. I tried the suggested approach of changing the divider height, but that did not end up looking all too pretty, even with an invisible divider. After some experimentation, I simply added an android:paddingBottom="5dip" to the last TextView layout element in the XML file that defines individual listView entries.
This ended up giving me exactly what I was trying to achieve via the use of android:layout_marginBottom. I found this solution to produce a more aesthetically pleasing result than trying to increase the divider height.
Instead of giving margin, you should give padding:
<ListView
android:id="#+id/listView1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:divider="#android:color/green"
android:dividerHeight="4dp"
android:layout_alignParentTop="true"
android:padding="5dp" >
</ListView>
OR
<ListView
android:id="#+id/listView1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:paddingTop="2dp"
android:divider="#android:color/green"
android:dividerHeight="4dp"
android:paddingLeft="1dp"
android:paddingRight="1dp"
android:paddingBottom="2dp"
android:paddingStart="0dp"
android:paddingEnd="0dp" >
</ListView>
Simplest solution with OP's existing code (list items already have got padding) is to add following code:
listView.setDivider(new ColorDrawable(Color.TRANSPARENT)); //hide the divider
listView.setClipToPadding(false); // list items won't clip, so padding stays
This SO answer helped me.
Note: You may face a bug of the list item recycling too soon on older platforms, as has been asked here.
you just need to make background transparent of list divider and make height according to your needed gap.
<ListView
android:id="#+id/custom_list"
android:layout_height="match_parent"
android:layout_width="match_parent"
android:divider="#00ffffff"
android:dividerHeight="20dp"/>
<ListView
android:clipToPadding="false"
android:paddingTop="10dp"
android:paddingBottom="10dp"
android:dividerHeight="10dp"
android:divider="#null"
android:layout_width="match_parent"
android:layout_height="match_parent">
</ListView>
and set paddingTop, paddingBottom and dividerHeight to the same value to get equal spacing between all elements and space at the top and bottom of the list.
I set clipToPadding to false to let the views be drawn in this padded area.
I set divider to #null to remove the lines between list elements.
Also one more way to increase the spacing between the list items is that you add an empty view to your adapter code by providing the layout_height attribute with the spacing you require. For e.g. in order to increase the bottom spacing between your list items add this dummy view(empty view) to the end of your list items.
<View
android:layout_width="match_parent"
android:layout_height="15dp"/>
So this will provide a bottom spacing of 15 dp between list view items. You can directly add this if the parent layout is LinearLayout and orientation is vertical or take appropriate steps for other layout. Hope this helps :-)
This will help you add the divider height.
getListView().setDividerHeight(10)
If you want to add a custom view, you can add a small view in the listView item layout itself.
I found a not-so-good solution for this in case you are using a HorizontalListView, since dividers don't seem to work with it, but I think it'll work either way for the more common ListView.
Just adding:
<View
android:layout_marginBottom="xx dp/sp"/>
in the bottomest View of the Layout you inflate in the adapter class will create spacing between items
In order to give spacing between views inside a listView please use padding on your inflate views.
You can use android:paddingBottom="(number)dp" && android:paddingTop="(number)dp" on your view or views you're inflate inside your listview.
The divider solution is just a fix, because some day, when you'll want to use a divider color (right now it's transparent) you will see that the divider line is been stretched.
A lot of these solutions work. However, if all you want is to be able to set the margin between items the simplest method I have come up with is to wrap your item - in your case the CheckedTextView - in a LinearLayout and put your margin formatting for the item in that, not the root-layout. Be sure to give this wrapping layout an id and create it along with your CheckedTextView in your adapter.
That's it. In effect, you are instantiating the margin at the item level for the ListView. Because the ListView does not know about any item layout - only your adapter does. This basically inflates the part of the item layout that was being ignored before.
Maybe you can try to add android:layout_marginTop = "15dp" and android:layout_marginBottom = "15dp" in the outermost Layout
