I want to build an expandable/collapsible TableRow. I have two rows and I want an expandable or collapsible button (like a small 'v') on the second row. Upon clicking the button, I want to expand the 2nd row with some other views. I am very new to android development, and I am not sure how to achieve this. This is what I currently have.

So here's how my grid view looks like:
a http://imageshack.com/a/img41/7857/roir.png
I use some online JSON parsing and get the image thumbnail links and then pass it on as an array to the custom adapter and it sets images for which I again use some 3rd party library etc. But the 3rd party library is just used to set the image to the imageview. That's it.
So I have a main FragmentActivity. It has 2 fragments inside of it. The textbox u see there is inside one fragment(search fragment) and on top of it, the gridview is held by the second fragment. (results fragment)
Code for the results fragment:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#f0f0f0"
tools:context="com.example.wikipicsearch.MainActivity" >
<GridView
android:id="#+id/gridView"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_margin="5dp"
android:columnWidth="100dp"
android:gravity="center"
android:numColumns="auto_fit"
android:verticalSpacing="5dp"
android:drawSelectorOnTop="true"
android:stretchMode="columnWidth" >
</GridView>
</RelativeLayout>
Code for the layout that I pass onto the custom Adapter:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
android:padding="5dp"
android:clickable="true"
android:background="#drawable/grid_color_selector"
android:focusable="true">
<ImageView
android:id="#+id/image"
android:layout_width="100dp"
android:layout_height="100dp"
android:layout_margin="0dp"
android:layout_gravity="center" >
</ImageView>
</LinearLayout>
Now, I have no clue why on earth is there no horizontal spacing between each of that linear layout. I tried using android:layout_marginLeft etc etc... nothing works at all! I made the fragment holding the gridview look grey so that the each element in the grid will leave some spacing and it should look good. Please help me out with this. TIA!
Android:horizontalSpacing="20dp" this doesn't work, if you have a fixed size in the root element (ex- card) of the item layout that you are setting for the grid
Set the width like this - android:layout_width="match_parent"
Activiy layout
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

I am making an app for my university's SafeWalk program and I am trying to make an activity that will display a map fragment with a button bar below it with emergency call buttons. The problem I am running in to is that when I load the following layout file, only the map fragment is displayed, and not the buttons along the bottom.
Note: I am also using a navigation drawer in this layout so I have included that code in case it is conflicting.
I have tried changing the layout_width and layout_height values of the two parent FrameLayouts
and I only can obtain one of two results, a full page of map, or a full page of my buttons (stretched to the top). I can attach the layout for the CallButtonFragment if necessary, but it is a horizontal linear layout with the button bar style containing two buttons.
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentTop="true"
android:orientation="vertical" >
<!-- The main content view -->
<FrameLayout
android:id="#+id/content_frame"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true" >
<fragment
android:id="#+id/map"
android:name="com.google.android.gms.maps.MapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</FrameLayout>
<FrameLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_below="#+id/content_frame" >
<fragment
android:id="#+id/titles"
android:name="edu.purdue.SafeWalk.CallButtonFragment"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</FrameLayout>
</RelativeLayout>
<!-- The navigation drawer -->
<ListView
android:id="#+id/left_drawer"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="#111"
android:choiceMode="singleChoice"
android:divider="#android:color/transparent"
android:dividerHeight="0dp" />
Following the suggestion of Android-er-naut below, I have this result:
(It is an improvement, but the buttons need to be a bit larger and fit the width of the screen.)
How about this -
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<!-- The main content view -->
<FrameLayout
android:id="#+id/content_frame"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1" >
<fragment
android:id="#+id/map"
android:name="com.google.android.gms.maps.MapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</FrameLayout>
<FrameLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1" >
<fragment
android:id="#+id/titles"
android:name="edu.purdue.SafeWalk.CallButtonFragment"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</FrameLayout>
</LinearLayout>
I wanna do such a layout in android, i can't figure it out.
one button on top, one button at bottom, and a listview take the rest center area, how to make the listview take the rest area? is this possible if parent container is vertical LinearLayout?
thanks
What i have done in my project is
<?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:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:text="#string/tasks" />
<ListView
android:id="#id/android:list"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_below="#id/task_title"
android:layout_above="#+id/add_button">
<!-- Preview: listitem=#layout/task_list_item -->

With relative layout you can simply do it, the key layout properties are android:layout_alignParentBottom="true" , android:layout_alignParentTop="true"
I have an app that I am putting together and I have a background on it. There is a header on top and a ListView in the middle. When I have a list in the middle that isn't at least as big as the screen it just shows gray not the background of the parent layout. The weird thing is that this doesn't happen on my older phone, the background fills the whole screen even if the list doesn't. Here is the xml:
<?xml version="1.0" encoding="utf-8"?>
<!-- This is the xml for HomeActivity, more information in HomeActivity.java -->
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/common_aboutLayout"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#drawable/bg">
<!-- This is the header on the top of the home screen -->
<LinearLayout android:id="#+id/dynamicBanner"
android:layout_height="wrap_content"
android:gravity="center"
android:background="#drawable/header"
android:layout_width="fill_parent">
<!-- This is the temp pop-up on start -->
<TextView android:text="#+id/TextView01"
android:id="#+id/titleText"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical|center_horizontal"
android:textColor="#FFFFFF"
android:visibility="invisible"
android:textStyle="bold"
android:typeface="sans"
android:ellipsize="end"
android:textSize="18sp"
android:gravity="center_vertical|center_horizontal">
</TextView>
</LinearLayout>
<!-- This is the layout of the list of ringtones. -->
<ListView android:id="#+id/homeListView"
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_weight="1">
</ListView>
<LinearLayout android:id="#+id/adLayout"
android:layout_width="fill_parent"
android:layout_height="0dp">
<com.admob.android.ads.AdView android:id="#+id/ad"
admob:textColor="#FFFFFF"
admob:keywords="Android application"
android:layout_width="fill_parent"
android:layout_gravity="bottom|center"
admob:backgroundColor="#666666"
admob:refreshInterval="30"
android:layout_height="0dp" />
</LinearLayout>
</LinearLayout>
The TextView is just a temp thing when the window first opens.
Just looking for some help, Thanks.
put All views in RelativeLayout.then put this admob layout and add a tag to plcae this to bottom of layout
like
android:layout_alignParentBottom="true"
<LinearLayout android:id="#+id/adLayout"
android:layout_width="fill_parent"
android:layout_height="0dp">
<com.admob.android.ads.AdView android:id="#+id/ad"
admob:textColor="#FFFFFF"
admob:keywords="Android application"
android:layout_width="fill_parent"
android:layout_gravity="bottom|center"
admob:backgroundColor="#666666"
admob:refreshInterval="30"
android:layout_height="0dp" />
</LinearLayout>
and then Header part inside the relative layout
android:layout_alignParentTop="true"
and the put the ListView and
android:layout_above="#+id/adLayout"
android:layout_below=HEADERVIEW
i want to display two buttons at the bottom of my activity screen, but each time i populate the screen with views that makes me scroll, the two buttons at the bottom of my screen disappears. when there is no need to scroll the buttons display fine.
please help
thanks.

Wrap the buttons along with the scrollable content(e.g:-Listview) in a scrollview and then display the content.
