How to anchor buttons at the bottom of the layout?

I'd like the OK / Cancel buttons to be anchored at the bottom (even when there's more items on the list that can be shown on the screen). Here's what it currently looks like:
The buttons are on the top, not on the bottom.
The layout that contains the buttons:
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:stretchColumns="true"
android:id="#+id/buttons_layout">
<TableRow>
<Button
android:id="#+id/btnOK"
android:background="#color/pomegranate"
android:text="OK"
android:layout_gravity="fill_horizontal"
android:layout_weight="1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"/>
<Button
android:id="#+id/btnCancel"
android:background="#color/wet_asphalt"
android:text="Cancel"
android:layout_weight="1"
android:layout_gravity="fill_horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content"/>
</TableRow>
</TableLayout>
The composite layout:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ListView android:id="#+id/options_list"
android:layout_width="fill_parent"
android:layout_height="match_parent">
</ListView>
<include layout="#id/buttons_layout"
android:layout_alignParentBottom="true"
android:layout_height="match_parent"
android:layout_below="#id/options_list"/>
</RelativeLayout>
I followed the guidelines I read on http://developer.android.com/guide/topics/ui/layout/relative.html
I tried this answer - https://stackoverflow.com/a/6285438/168719 - it hasn't helped me.
I suspected that it might not work because the list view doesn't "know" how tall it is, so the button layout doesn't know where to place itself, either. But I ruled it out by setting the ListView height to an arbitrary value like 100dp. The buttons are still superimposed over it.
I fiddled with all the layout attributes, but I can't get it to work.
Apart from the solution, I would also like to know why mine doesn't work...

the layout should be something like this :
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ListView android:id="#+id/options_list"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="#+id/layout_buttons" >
</ListView>
<include android:id="#+id/layout_buttons"
layout="#id/buttons_layout"
android:layout_alignParentBottom="true"
android:layout_height="wrap_parent"
android:layout_width="wrap_content"/>
</RelativeLayout>

you can use tab to do it
you can see this tutorial
Android Tab Layout Tutorial

you could try using it this way
<relativelayout1>
<relativelayout2 specify layout below listview with id="list">
<button1>
<button2>
</relativelayout2>
<listview id="list">
</listview>
</relativelayout1>
so this will ensure no matter how long your list is you always get the buttons below your list. so you can have a scrolling list and a static buttons below the list

try this. Put the include tag inside another RelativeLayout, then be sure ListView is above the new RelativeLayout
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/parentLayout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<RelativeLayout
android:id="#+id/buttonsContent"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true" >
<include
android:id="#+id/buttons"
android:layout_width="wrap_content"
layout="#layout/buttons_layout" />
</RelativeLayout>
<ListView
android:id="#+id/options_list"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:layout_above="#id/buttonsContent" >
</ListView>
</RelativeLayout>

Try like this
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="#+id/layout_buttons"
android:orientation="vertical" >
<ListView android:id="#+id/options_list"
android:layout_width="match_parent"
android:layout_height="match_parent">
</ListView>
</LinearLayout>
<include android:id="#+id/layout_buttons"
layout="#id/buttons_layout"
android:layout_alignParentBottom="true"
android:layout_height="wrap_parent"
android:layout_width="wrap_content"/>
</RelativeLayout>

Scroll PullToRefreshScrollview automatically in android

I have a Listview, FrameLayout inside PullToRefreshScrollview. And I'm loading a fragment into framelayout. Data is loading into listview using lazy adapter. I'm able to see the fragment/framelayout while listview is loading. But Scrollview is automatically scrolling to the postion of listview after data is loaded into listview and framelayout is not visible. How can I scroll the scrollview to top? Please help me. Thanks in advance
<?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="#color/app_bg"
android:orientation="vertical" >
<com.handmark.pulltorefresh.library.PullToRefreshScrollView
xmlns:ptr="http://schemas.android.com/apk/res-auto"
android:id="#+id/ptrScrollView"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_marginBottom="5dp"
android:layout_weight="1"
android:paddingBottom="5dp"
ptr:ptrMode="pullUpFromBottom" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<FrameLayout
android:id="#+id/frame"
android:layout_width="match_parent"
android:layout_height="wrap_content">
</FrameLayout>
<com.xxxx.yyyy.CustomListView
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/listView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/app_bg"
android:focusable="false" />
<ProgressBar
android:id="#+id/spinner"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:visibility="gone" />
</LinearLayout>
</com.handmark.pulltorefresh.library.PullToRefreshScrollView>
</LinearLayout>

Here is the aproach I took
Lets say you have a reference to the PullToRefreshScrollView like so
PullToRefreshScrollView myRefreshScrollView = (PullToRefreshScrollView)findViewById(R.id. ptrScrollView);
To get the ACTUAL ScrollView object you need to call getRefreshableView() like so
ScrollView myScrollView = myRefreshScrollView.getRefreshableView();
and then scroll this object
myScrollView.scrollTo(0,0);
or
myScrollView.smoothScrollTo(0,0)

There are 2 teps to make it works:
you should set android:smoothScrollbar="true" in layout xml :
<com.handmark.pulltorefresh.library.PullToRefreshListView
android:id="#+id/news_list_listView_main"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#EEE"
android:cacheColorHint="#00000000"
android:divider="#00000000"
android:dividerHeight="5dp"
android:layout_marginTop="2dp"
android:paddingLeft="1dp"
android:paddingRight="1dp"
android:smoothScrollbar="true"/>
and Then,
myRefreshScrollView.getRefreshableView().smoothScrollToPosition(lastScollCount);

android Layouts overlapping ListView and LinearLayout

I am using FrameLayout in which I am having a search Textbox and Button and a ListView to be displayed in the next line of the TextBox
My layout is like this ,
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >

I am using this TextView to diplay List item in the ListView,
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/txtsimple_list"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="60dp"
android:gravity="center_vertical"
android:textSize="20sp"
android:textStyle="bold" />
I have given margin top attribute for the ListView, but even though it overlaps on the Button and EditText controls.
I am using a FrameLayout but of no use. Please suggest me any help!!
Any help is appreciated!!

You should use LinearLayout as parent, just set android:orientation="vertical".
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<ImageView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:scaleType="fitXY"
android:src="#drawable/pattern1" />
<LinearLayout
android:id="#+id/LinearLayout02"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:layout_gravity="top" >
...
</LinearLayout>
<ListView
android:id="#+id/list_customers"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="bottom|center_horizontal" >
...
</ListView>
</LinearLayout>

FrameLayout has no 'rules of placement' so everything just stacks on to each other.
Instead, use a LinearLayout with android:orientation="vertical"
or use a RelativeLayout and add positioning values to the childs, such as android:layout_below

+1 Neoh and remove imageview, instead put the image as background image attribute at parent view
android:background="#drawable/pattern1"

FrameLayout are used very less,beacuse they are used to display single view or views which overlaps each other.
So you should use RelativeLayout.

FrameLayout is not the best option. You can use other layouts, eg, GridLayout, RelativeLayout or ListView.

Use ListView as background of TextView

I have the below layout which contain mainly:
Relative layout, which act as header with Textview and button.
and Listview.
I would like to make the "header" which is the above relative layout to be transparent and show the listview as user scroll down the list view.
I know how to make the layout transparent, but I dont know how to show the listview as background for the "header".
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/buttonlayout2"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:background="#FFDBE2ED"
android:paddingBottom="0dp"
android:paddingTop="0dp"
>
<TextView
android:id="#+id/txtTest"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:gravity="center_vertical"
android:layout_centerVertical="true"
android:paddingLeft="0dp"
android:text="#string/list_header"
android:textColor="#000000"
android:textSize="25sp"
android:textStyle="bold">
</TextView>
<Button
android:id="#+id/btnClear"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginBottom="0px"
android:layout_marginLeft="10px"
android:layout_marginRight="3px"
android:layout_marginTop="6px"
android:height="0dp"
android:text="Clear"
android:textSize="15sp"
android:width="70dp"
android:layout_alignParentRight="true"
>
</Button>
</RelativeLayout>
<ListView
android:id="#+id/mylist1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_above="#+id/form"
android:layout_alignParentTop="true" >
</ListView>
</LinearLayout>

You are using a LinearLayout as the root container and in linear layout the views are placed one over the other so you cannot overlap one view over the other. If you want an overlapping effect you can use either the FrameLayout or the RelativeLayout as the root container.
Using RelativeLayout is a better option.
Here is sample code for this:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<ListView
android:id="#+id/list"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
</ListView>
<Button
android:id="#+id/view"
android:layout_width="fill_parent"
android:layout_height="100dp"
android:background="#00cc0000"
android:layout_alignParentTop="true" />
</RelativeLayout>
Here the button is overlapping the list view.
I hope this will help :)

Try moving the ListView inside of your RelativeLayout, as the first element (this ensures that it's in the back). This way, the other views are just on top of the ListView, and if you make them transparent you should get the desired effect!
Oh, and you should make the ListView then fill the RelativeLayout:
<ListView
android:id="#+id/mylist1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentTop="true" >
</ListView>
, and make the RelativeLayout fill the screen:
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/buttonlayout2"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
...

How to place both listview and textview in one page in android?

I am displaying a TextView and below that a ListView in one page. My code is:

Here I am displaying the ListView data dynamically....but in my emulator it is displaying a TextView at the top and then the ListView with scroll...It is not expanding the list and instead it is scrolling with the content which is generated dynamically...Please tell me how to expand the entire ListView....
Thanks in advance

<?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">
<LinearLayout android:gravity="center|center_vertical"
android:orientation="vertical" android:layout_height="fill_parent" android:layout_width="fill_parent">
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="status"
android:id="#+id/txtvw1">
</TextView>
<ListView
android:layout_width="fill_parent"
android:id="#+id/listlist"
android:layout_height="fill_parent">
</ListView>
</LinearLayout>
</LinearLayout>

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<TextView
android:id="#+id/txtvw1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="status" >
</TextView>
<ListView
android:id="#+id/listlist"
android:layout_width="fill_parent"
android:layout_height="fill_parent" android:layout_weight="1">
</ListView>
</LinearLayout>

You have an error here
<ListView
android:layout_width="fill_parent"
android:id="#+id/listlist" //error here
android:layout_height="fill_parent">
</ListView>
the ListView is filled of the LinearLayout
so that you can't get the TextView.
instand of this
you can layout your view as follows:
<ListView
android:layout_width="match_parent"
android:id="#+id/listlist" //error here
android:layout_height="0"
android:layout_weight="1.0>
android:layout_weight="1.0" //this will make the list view filled with the rest of the screem
Further more
I suggest you use "match_parent" instand of "fill_parent"
this WAS CHANGED in the SDK level 8...

OK, now you use the RelativeLayout install of the LinearLayout
So you should add the relationship with your views in your layout.
You can layout as this:
<RelativeLayout
android:id="#+id/widgetlay"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<TextView
android:id="#+id/txt1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="" >
</TextView>
<ListView
android:id="#+id/listlist"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#id/txt1" />
android:layout_below="#id/txt"----Indicate the relationship with the layout
The RelativeLayout does not have the attr "orientation" and "layout_weight". So I don't suggest you to use this layout, It can't be fixed with the screen height in that way.
The good layout is:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<TextView
android:id="#+id/txtvw1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="status" >
</TextView>
<ListView
android:id="#+id/listlist"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1.0" />
Further more, what do you want to layout your views?

This is a part of my work. List view will appear in the middle of your screen and what ever u need at the top, put it in place of header() and things that u need in bottom of the screen , put it in place of footer(). U can use relative layout instead of the linear layout
Hope this helps.

I don't know what is meaning of expanding meaning here, but listView in scroll view dont behave normally. To resolve this issue you need to implement list view outside of scrollview.

I don't quite understand what you mean, but if you want to have the textView scroll with the content of the listView, you need to add it as a header in your listView.
Moreover, it is not a good idea to put a listview in a scrollview, the listview being scrollable, it messes with the scrollview mechanism.

You can NEVER ever place a listview in the SCrollView.It wont behave properly.Instead of it try using LinearLayout TextView ListView < /Linearlayout>
