everyone.
Can you help me with setting footer to ListView? I've described footer in layouts, and then:
View footer = getLayoutInflater().inflate(R.layout.bottom, getListView(), false);
getListView().addFooterView(footer);
But it didn't appear... Can you give an example? Also I need to set the height of footer dynamically. Here is the code of footer:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#87ceeb"
>
<TextView android:id="#+id/loading"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:textColor="#000000"
android:textStyle="bold"
android:text="Loading..."/>
</LinearLayout>
There can be few reasons for this,
Have you added your code
getListView().addFooterView(footer); before the setAdapter of ListView ? If yes.
There might be problem in xml layout,
If your listview is wrap_content and your footerlayout has fill_parent , Footer might not appear unless some text is there in your textview of footer layout.
Change the listview layout_width="fill_parent" and footer layout's layout_width="fill_parent"
To quickly check , give a background color to your footer layout and see its placement.
Hope it helps.
The best way to do this is with RelativeLayout.
1) Create a RelativeLayout for the whole layout.
2) Create two views, perhaps ListView and LinearLayout for the footer.
3) Make the listView aligned to the parent top with a bottom margin equal to the height of the footer view or linear layout.
4) make the linear layout aligned the parent bottom
Done. Hope this helps.
EDIT:
Some quick code to try and get the point across:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="fill_parent"
android:layout_width="fill_parent" >
<ListView
android:id="#+id/list"
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:layout_marginBottom="50dp"
android:layout_alignParentTop="true" />
<TextView
android:text="Some text"
android:gravity="center"
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:layout_alignParentBottom="true" />
</RelativeLayout>

I want to create the layout to be like what in the diagram
how can I make the listView Scroll independently and make the textView and ImageView stead?
just replace your xml layout like below code:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#android:color/white"
android:padding="5dp"
android:weightSum="2"
android:orientation="vertical" >
<LinearLayout android:layout_width="fill_parent" android:layout_height="0dp" android:layout_weight="1" android:orientation="vertical">
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Small Text"
android:layout_gravity="right"
android:textColor="#android:color/black"
android:textAppearance="?android:attr/textAppearanceSmall" />
<ListView
android:id="#+id/listView1"
android:layout_width="match_parent"
android:layout_height="match_parent">
</ListView>
</LinearLayout>
<ImageView
android:id="#+id/imageView1"
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:src="#drawable/yourimg" />
</LinearLayout>
above xml given output below screenshot:
For the Lower Steady Image View you can use : Create a footer view
layout consisting of text that you want to set as footer and then try
View footerView = ((LayoutInflater) ActivityContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE)).inflate(R.layout.footer_layout, null, false);
ListView.addFooterView(footerView);
For Header: The solution that works for me is to create a TableLayout
that has a row with the heading and a row with the list like this:
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<include layout="#layout/header" />
<ListView
android:id="#android:id/list"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>
</TableLayout>
Please make sure that the ListView has #android:id/list as the ID.
OR
Rather google adding header and footer to listview in android that
will help u much better
Sorry for the pseudo code, I can try a better attempt later on, but you need:
RelativeLayout
TextView - align top
ImageView - align bottom
ScrollView - align above ImageView, align below TextView
Create a linear layout with orientation as vertical. Add textview listview and imageview with the weight as you want. Remember to give layout_height as 0dp for all the three components.
Add Header And Footer To the Listview,Like
ListView mList=getListView();
mList.addHeaderView(View v);//Your textView
and
mList.addFooterView(v);//your imageview
I'm having issues with a Fragment consisting of a ScrollView containing a LinearLayout. I'm trying to create an effect where the LinearLayout has a white background and looks like a piece of paper scrolling on a coloured background. The way that I'm trying to achieve this is by having the ScrollView occupy the full space of the fragment and then the LinearLayout inside has android:layout_margin="16dp" to create the space around the "paper".
This way, the scroll bar of the ScrollView appears in the coloured background area, the margin at the top scrolls away along with the content and the margin at the bottom only scrolls in when one reaches the end.
Unfortunately in this configuration the ScrollView won't scroll all the way to the end and in fact cuts off a very small amount of the text at the bottom. I suspect that the ScrollView isn't taking into account its child's margins in its vertical scrolling distance. To solve this I've wrapped the LinearLayout in a FrameLayout which solves the issue, but seems superfluous. Any pointers on how to eliminate this unneeded container would be appreciated.
Note: setting android:padding="16dp" on the ScrollView and scrapping the margins doesn't have the desired effect, as then the padding appears on all four edges continuously, regardless of scroll position.
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
tools:context=".ArticleFragment" >
<!-- This FrameLayout exists purely to force the outer ScrollView to respect
the margins of the LinearLayout -->
<FrameLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:padding="10dp"
android:layout_margin="16dp"
android:background="#color/page_background" >
<TextView
android:id="#+id/article_title"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceLarge"
android:textIsSelectable="true" />
<TextView
android:id="#+id/article_content"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textIsSelectable="true" />
</LinearLayout>
</FrameLayout>
</ScrollView>
I remember having trouble with the ScrollView somehow not making it to the end of it's contents when the content layout had a top margin. I solved the problem with a little hack, adding an empty view to the end of the LinearLayout:
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
tools:context=".ArticleFragment" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:padding="10dp"
android:layout_margin="16dp" >
<TextView
android:id="#+id/article_title"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceLarge"
android:textIsSelectable="true"
android:background="#color/page_background" />
<TextView
android:id="#+id/article_content"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textIsSelectable="true"
android:background="#color/page_background" />
<!-- Add a little space to the end -->
<View
android:layout_width="fill_parent"
android:layout_height="30dp" />
</LinearLayout>
</ScrollView>
I used a similar empty view also in the beginning of the LinearLayout to avoid top/bottom margins completely.
EDIT: I just realised that you also wanted the end of the "paper" to show up when reaching the end of the view. In that case you might want to set the background color to the TextViews instead of the layout itself. Then make sure there's no margin between the title and the article (use padding as separation).
EDIT2: I should learn to check when the questions were asked... Well, maybe this still helps someone. :)
The question is old, but I've had issues with ScrollView being ill-behaved when wrapping FrameLayout. It also doesn't seem to consider the margins of contained layouts. You could replace the FrameLayout with another single-child LinearLayout, which should measure correctly. I would've removed the FrameLayout completely and simply added summed margin with padding on the inner layout:
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:padding="26dp"
android:background="#color/page_background" >
<!--...-->
I'd get rid of the FrameLayout and make the LinearLayout the child of the ScrollView with match_parent set as the layout height. If that still doesn't work, consider replacing the bottom margin with another arbitrary View with the desired height and background as the last item in the LinearLayout.
I searched already but unfortunately found no real solution to this. I have added a footer to a listview with:
View footer = getLayoutInflater().inflate(R.layout.listfooter, null);
listview.addFooterView(footer);
The xml for the footer looks like this:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/footer"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:textColor="#FFFFFFFF"
android:orientation="vertical"
android:layout_alignParentBottom="true"
android:background="#ee222222"
>
<TextView
android:id="#+id/info"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:text="Test Test Test"
android:layout_alignParentBottom="true"
android:layout_gravity="center_vertical"
/>
</LinearLayout>
It does display a footer only as a single line
I change the number of rows in the list dynamically but I want the footer to always fill the rest of the listview if there are not enough items in it.
How can I do this?
Edit: I added an image, the left is how it is right now and the 2 on the right is what I want.
I can say the best solution can be for this problem is.
1) Create a XMl layout which must have hierarchy like this.
<Liniear Layout>
<ScrollView>
<LinearLayout>
<ListView>// add your list data here.
<\ListView>
<TextView><TextView>// for footer text
<\LinearLayout>
<ScrollView>
<LinearLayout>
Please let me kno if anything, I hope this approach will work as I tried it myself.
I want the footer to be anchored at the bottom of the screen if and only if it can be anchored there without overlapping any other views.
The problem is that I don't know how many views are going to be added to the header or the footer.
If putting the footer at the bottom of the window would make it overlap, I want to put the footer at the bottom of the scrollview. (Maybe by adding it to the RelativeLayout with the rule that it needs to be below the top component?)
Here is a pic of what I'm trying to get:
desired result
Where:
1)The RelativeLayout contains both the TableLayout at the top, and the LinearLayout at the bottom.
2)The TableLayout expands downwards as TableRows get added to it.
3)The LinearLayout expands up from the bottom as views get added to it.
~~~
I'd like for the scrollview to grow in size only enough to fit the components without overlapping.
Thanks in advance for such awesome community support
I think you can solve it in linear layout. You set three blocks in linear layout: header, body, footer. Set body to fill_parent and layout_weight=1, this way body will expand to fill what left after header and footer taken its part from parent. Whole structure place into ScrollView.
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:fillViewport="true">
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TableLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<TableRow><TextView android:text="Text1"/></TableRow>
<TableRow><TextView android:text="Text2"/></TableRow>
</TableLayout>
<RelativeLayout
android:layout_weight="1"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView
android:text="#string/lorem_ipsum"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
</RelativeLayout>
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<TextView
android:text="Text3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
<TextView
android:text="Text4"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
</LinearLayout>
</LinearLayout>
</ScrollView>
I tested this in Emulator of Android 2.1 and it looks it works.
I've a ScrollView / RelativeLayout / FrameLayout and I inside put programmaticaly some widgets.
Here is the gui xml :
<?xml version="1.0" encoding="utf-8"?>
<ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:fillViewport="true"
android:background="#drawable/fond_app">
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
>
<TextView
android:id="#+id/titreAppli"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="My Big Application"
android:textStyle="bold"
android:textColor="#9b9b71"
android:textSize="15dp"
/>
<FrameLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="#+id/out"
android:layout_below="#id/titreAppli"
/>
</RelativeLayout>
</ScrollView>
In the FrameLayout, I put programaticaly another RelativeLayout, and other widgets inside.
With some widgets (text, image, buttons), I can't scroll. With other (a linearlist with text), I can scroll.
Why ? Is there a solution ?
Thanks.
First remove frame layout. You should use some other layout like relative instead of framelayout. Becasue Framelayout is not expanding and there fore scroll view is not working. If you use linear or relative then they will expand and you will be able to scroll.
Have you tried without the android:fillViewport="true" ?
