I have a view which contains a top view (it's a mapview but it's not implemented yet) and a listview below it.
What I'm trying to do is to make the top of listview to be overlay the bottom of the top view a little bit. Here is something similar to what I'm trying to achieve :
(without the tab headers and the image will be the mapview)
I'm not sure how I can achieve that, here is what I have so far:
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<View
android:id="#+id/map"
android:layout_width="match_parent"
android:layout_height="250dp"
android:background="#android:color/holo_red_dark">
</View>
<com.hmm.widgets.CustomListView
android:id="#+id/runners_list"
android:background="#android:color/darker_gray"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:dividerHeight="10dp"
android:divider="#android:color/darker_gray">
</com.hmm.widgets.CustomListView>
</RelativeLayout>
I've tried negative margin which didn't work. I'm not sure how can I achieve something similar. Should I be using FrameLayout?
You can use LinearLayout in your case and design the layout like this. This is a trick of setting a negative layout_marginTop to your custom ListView
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:orientation="vertical"
android:layout_height="match_parent">
<View
android:id="#+id/map"
android:layout_width="match_parent"
android:layout_height="250dp"
android:background="#android:color/holo_red_dark">
</View>
<com.hmm.widgets.CustomListView
android:id="#+id/runners_list"
android:background="#android:color/darker_gray"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginLeft="#dimen/activity_vertical_margin"
android:layout_marginRight="#dimen/activity_vertical_margin"
android:dividerHeight="10dp"
android:layout_marginTop="-40dp"
android:divider="#android:color/darker_gray">
</com.hmm.widgets.CustomListView>
</LinearLayout>
Complementing Reaz's answer, you can do it with RelativeLayout too without using negative margins (which are a bit controversial).
Note the last four attributes in the CustomListView: you constraint the height with alignParent*, set a dummy height which will be discarded, and offset the view from the top with a margin. The "negative offset" will be 250dp - 200dp = 50 dp.
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<View
android:id="#+id/map"
android:layout_width="match_parent"
android:layout_height="250dp"
android:background="#android:color/holo_red_dark">
</View>
<com.hmm.widgets.CustomListView
android:id="#+id/runners_list"
android:background="#android:color/darker_gray"
android:layout_width="match_parent"
android:dividerHeight="10dp"
android:divider="#android:color/darker_gray"
android:layout_height="0dp"
android:layout_marginTop="200dp"
android:layout_alignParentTop="true"
android:layout_alignParentBottom="true">
</com.hmm.widgets.CustomListView>

How to set the background to white (view layout) below my search component? Here is my code
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal">
<include
layout="#layout/component_search"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="8dp"
android:layout_marginTop="8dp"/>
<View
android:layout_width="match_parent"
android:layout_height="30dp"
android:background="#color/white"
android:elevation="1dp"/>
</RelativeLayout>
If by below you mean in the y axe, such as in a row after another, what you already have is probably fine. Having the items one after the other inside your relative layout. You can even force this position by using android:layout_toBottomOf="#+id/your_view_above"
Now if by below you mean on the z axe, the one coming down the screen in your direction, (behind) you may want to do as #amit suggested and use elevation instead.
Just Change the order of include tag and View tag like this:
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<View
android:layout_width="match_parent"
android:layout_height="30dp"
android:background="#color/white"/>
<include
layout="#layout/component_search"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="8dp"
android:layout_marginTop="8dp"/>
</RelativeLayout>
Update: android:orientation="horizontal" was there by mistake as I edited LinearLayout to make it RelativeLayout. You don't need to add that in your RelativeLayout.
Give an id to the include view like search,
set its layout_alignParentTop attribute to true and
set the View's layout_below attribute to "#id/search":
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<include
android:id="#+id/search"
layout="#layout/component_search"
android:layout_alignParentTop="true"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="8dp"
android:layout_marginTop="8dp"/>
<View
android:layout_below="#id/search"
android:layout_width="match_parent"
android:layout_height="30dp"
android:background="#color/white"
android:elevation="1dp"/>
</RelativeLayout>
You don't need this attribute android:orientation="horizontal", since it does not apply to a RelativeLayout.
I trying to create a relative layout that look like toolbar but I keep on having such height problem as shown below:
What I want is:
Here's my code:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.Toolbar
android:id="#+id/Searchtoolbar"
android:layout_height="?attr/actionBarSize"
android:layout_width="match_parent"
android:background="#color/Toolbar_default_color"
android:minHeight="?attr/actionBarSize">
</android.support.v7.widget.Toolbar>
<RelativeLayout
android:layout_below="#+id/Searchtoolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<RelativeLayout
android:id="#+id/FilterLayout"
android:layout_width="match_parent"
android:layout_height="40dp">
<ImageButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/search_filter_icon"
android:background="#drawable/search_filter_bgn_btn"
android:layout_marginRight="10dp"
android:layout_marginBottom="10dp"
android:layout_alignParentRight="true"
android:layout_alignParentBottom="true"/>
</RelativeLayout>
<ListView
android:id="#+id/feed_listview"
android:layout_below="#+id/FilterLayout"
android:layout_marginTop="?attr/actionBarSize"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:divider="#null" />
</RelativeLayout>
</RelativeLayout>
In your ImageButton use: android:layout_height="match_parent"
instead of android:layout_height="wrap_content"
Or resize your Image using photoshop or any other free tool to fit 40dp exactly.
WRAP_CONTENT: which means that the view wants to be just big enough to enclose its content (plus padding)
What you need:
MATCH_PARENT: which means that the view wants to be as big as its parent (minus padding)
Documentation.
I found my bad and silly mistake. It was the "android:layout_marginTop="?attr/actionBarSize" under the listview that causes the white layout to be extended. After I removed that line, I got what I wanted. =)
So I'm having some trouble with a RecyclerView in a layout file
Here it is:
<android.support.v7.widget.RecyclerView
android:id="#+id/chat_listview"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingRight="#dimen/abc_action_bar_default_padding_material"
android:paddingLeft="#dimen/abc_action_bar_default_padding_material"
/>
<LinearLayout
android:layout_below="#id/chat_listview"
android:layout_width="match_parent"
android:layout_height="#dimen/bottom_bar_height"
android:orientation="horizontal"
>
<EditText
android:id="#+id/chat_input_edittext"
android:layout_weight="7"
android:layout_width="0dp"
android:layout_height="match_parent"
android:inputType="textAutoCorrect"
/>
<Button
android:id="#+id/chat_send_button"
android:layout_weight="1"
android:layout_width="0dp"
android:layout_height="match_parent"
android:background="#drawable/ic_action_send_now"
/>
</LinearLayout>
The RecyclerView is visible and scrollable but the LinearLayout and the Views inside are not visible... I tried quite a few things but nothing has worked so far.
Can any of you please point me into the right direction?
Many thanks in advance!
When RecyclerView is drawn, it calculates all the remaining size on screen to itself before drawing the next elements and don't recalculate after the other elements are drawn, leaving them outside the screen.
The trick is to draw all other elements first, and leave RecyclerView for last. FrameLayout does not work anymore so use a relative layout and put the RecyclerView last on the XML layout file.
Example to add a bar with buttons below the RecyclerView:
<?xml version="1.0" encoding="utf-8"?>
<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:padding="16dp"
tools:context=".MainActivity"
>
<LinearLayout
android:id="#+id/pagination_btns"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:layout_alignParentBottom="true"> //HERE YOU ALIGN THIS ELEMENT TO THE BOTTOM OF THE PARENT
<Button
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:text="#string/previous_btn_label"/>
<Space
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"/>
<Button
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:text="#string/next_btn_label"/>
</LinearLayout>
<android.support.v7.widget.RecyclerView
android:id="#+id/items_recycler_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:scrollbars="vertical"
android:layout_above="#id/pagination_btns"/> //HERE YOU ALIGN THE RECYCLERVIEW ABOVE THE PAGINATION BAR
</RelativeLayout>
Change the root view to a FrameLayout. Set the gravity of the LinearLayout to bottom
<FrameLayout 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.support.v7.widget.RecyclerView
android:id="#+id/chat_listview"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingRight="#dimen/abc_action_bar_default_padding_material"
android:paddingLeft="#dimen/abc_action_bar_default_padding_material"
/>
<LinearLayout
android:layout_below="#id/chat_listview"
android:layout_width="match_parent"
android:layout_height="#dimen/bottom_bar_height"
android:layout_gravity="bottom"
android:orientation="horizontal">
<EditText
android:id="#+id/chat_input_edittext"
android:layout_weight="7"
android:layout_width="0dp"
android:layout_height="match_parent"
android:inputType="textAutoCorrect"/>
<Button
android:id="#+id/chat_send_button"
android:layout_weight="1"
android:layout_width="0dp"
android:layout_height="match_parent"
android:background="#drawable/ic_action_send_now"/>
</LinearLayout>
</FrameLayout>
Alternatively, you can wrap the linear layout in a FrameLayout
and set it to align_parentBottom = true if it is a relative layout or a linear layout at your root and you have other things in your view.
I am building an app that uses this library:https://github.com/umano/AndroidSlidingUpPanel to create a panel that slides on from the bottom of the screen when a user clicks an item in a listview.
However i dont want the slide up panel to take up the entire screen. I need there to be a gap at the top, between the panel and the action bar, of exactly 80dp.
I have tried everything i can think of (putting a spacer there with a transparant background, using layoutParams (gives error), etc). But nothing seems to work.
If someone could give me some suggestions as to what i could try next, i would much appreciate it.
The xml layouts are below.
Thanks for your time.

What about wrapping your SlidingUpPanelLayout in another layout, say FrameLayout and adding some good old paddingTop to the latter?
I have found a workaround. Draw the background of the pane transparent and put a padding top, but first the library must be modified like it's written here:
https://github.com/umano/AndroidSlidingUpPanel/issues/4
Hope this helps somebody in the future :)
I know this is a common question , but I am completely messed with those different examples and tutorials available on the web.
I have a horizontalScrollView where I add some view dynamically , and I want to set a guestureListener for swiping through the Views . Each view's with is equal to the width of the screen.
You can use the View Pager instead of the horizontalScrollView. http://developer.android.com/reference/android/support/v4/view/ViewPager.html
To keep the View pager at half the screen use something like this:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/White"
android:orientation="vertical">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1.5">
<android.support.v4.view.ViewPager
android:id="#+id/pagerPromo"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
<com.viewpagerindicator.CirclePageIndicator
android:id="#+id/indicatorPromo"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:padding="5dp"
android:layout_alignParentBottom="true"/>
</RelativeLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1.0"
android:orientation="vertical">
This View Pager has a circle indicator at the bottom but you can remove that if you like. Just play around with the weights and see what works best for you.
