Android: Center two elements in a Linear Layout

I want that both elements are centered and without that stretching.
Also, it would be great if the weight was not that wide.
This is how it looks like:
Heres the code:
android:layout_width="match_parent"
android:layout_height="fill_parent"
android:background="#color/listColor"
android:layout_weight="1"
android:orientation="vertical"
>
<TextView
android:layout_width="match_parent"
android:layout_height="fill_parent"
android:layout_weight="1"
android:background="#drawable/layout_item_value"
android:text="163,00"
android:textSize="18.2dp"
android:gravity="center_vertical|center_horizontal"
android:id="#+id/txtListValue"
android:textColor="#color/back"
/>
<ImageView
android:id="#+id/image_order"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_weight="1"
android:scaleX="0.4"
android:scaleY="0.4"
android:gravity="center_vertical|center_horizontal"
/>
Thank You in advance!

Its very simple, you can maintain it with the parent layout itself
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#ffffff"
android:orientation="vertical"
android:gravity="center">
<TextView
android:id="#+id/txtListValue"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#FF1493"
android:text="163,00"
android:textColor="#000000"
android:textSize="30sp" />
<ImageView
android:id="#+id/image_order"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:src="#mipmap/ic_launcher" />
</LinearLayout>

try this layout:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#ffffff"
android:orientation="vertical"
android:weightSum="2">
<TextView
android:id="#+id/txtListValue"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:background="#FF1493"
android:gravity="center_vertical|center_horizontal"
android:text="163,00"
android:textColor="#000000"
android:textSize="30sp" />
<ImageView
android:id="#+id/image_order"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:gravity="center_vertical|center_horizontal"
android:scaleX="0.4"
android:scaleY="0.4"
android:src="#mipmap/ic_launcher" />
</LinearLayout>
Output:

You can use below API without weightsum...
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"

Android, layout_above not working

I want to display some text in the middle of the screen, below header and above footer. Since this text is very long I nested it in ScrollView. I have tried a number of solutions: this, this, this, this, and a bunch more...
At first I had a problem of the two relative_layouts overlapping and text being cut of. The most accepted answer is to use layout_above and layout_below, but when I use layout_above, the text is never displayed.
This is what my xml looks like:
<?xml version="1.0" encoding="utf-8"?>

In you layout using two properties that why it doesn't work. So you can remove one properties here is your working code
<RelativeLayout
android:id="#+id/scrollViewAndStuff"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_below="#+id/linear_layout_header">
<ScrollView
android:id="#+id/scrollView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginLeft="20dp"
android:layout_marginRight="20dp"
android:layout_marginTop="10dp">
<TextView
android:textColor="#000"
android:id="#+id/meetupDescription"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginLeft="5dp"
android:text="#string/text" />-
</ScrollView>
</RelativeLayout>
you can use this android:layout_below="#+id/linear_layout_header or this android:layout_above="#+id/ln_layout_footer, one property at a time. or simply copy and past

I have using recycle view inside nested Scroll view but Recycle view not scroll down in nested scroll view.recycle view scroll down when keyboard open and new item add in recycle view.here is above my code.

First of all this is bad layout technique you have implement
According to android standard there are no more than two Scrolling views inside one layout
Make a proper layout for same

You should disable scrolling of recyclerview :
recycler.setNestedScrollingEnabled(false);
You should also set height of recyclerview to wrap_content
android:layout_height="wrap_content"
How to put RecyclerView inside NestedScrollView?

trying to position my checkbox above the keyboard in XML

My activity looks like this:
I use this XML :
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
tools:context=".MainActivity">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
>
<SearchView
android:layout_width="0px"
android:layout_height="wrap_content"
android:background="#5b74a8"
android:padding="4dp"
android:id="#+id/searchView"
android:singleLine="true"
android:layout_gravity="right"
android:layout_weight="7">
</SearchView>
<ImageButton
android:layout_height="match_parent"
android:layout_width="wrap_content"
android:id="#+id/settingsButton"
android:src="#drawable/settingsicon"
android:background="#drawable/ambuttonstatessettings"
android:layout_gravity="center_horizontal"
android:layout_weight="1"
android:onClick="settingsPopUp"
/>
</LinearLayout>
<ListView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/contacts_list"></ListView>
</LinearLayout>
But I want it to look like this, with a checkbox above the keyboard. Or if the keyboard is not there, the checkbox should be at the bottom :
Any idea how I can do this ? I tried this code, which is the closest I've come (basically, making a new linear layout at the bottom) but I can't get it right. And can't figure out why.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
tools:context=".MainActivity">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
>
<SearchView
android:layout_width="0px"
android:layout_height="wrap_content"
android:background="#5b74a8"
android:padding="4dp"
android:id="#+id/searchView"
android:singleLine="true"
android:layout_gravity="right"
android:layout_weight="7">
</SearchView>
<!--android:drawableLeft="#android:drawable/ic_menu_search"-->
<!--android:queryHint="howdy"-->
<ImageButton
android:layout_height="match_parent"
android:layout_width="wrap_content"
android:id="#+id/settingsButton"
android:src="#drawable/settingsicon"
android:background="#drawable/ambuttonstatessettings"
android:layout_gravity="center_horizontal"
android:layout_weight="1"
android:onClick="settingsPopUp"
/>
</LinearLayout>
<ListView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/contacts_list"></ListView>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="60dp"
android:orientation="horizontal" >
<CheckBox
android:layout_height="match_parent"
android:layout_width="0dp"
android:background="#ffa500"
android:text="New CheckBox"
android:id="#+id/checkBox"
android:layout_weight="1"
/>
</LinearLayout>
</LinearLayout>

try this:
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
tools:context=".MainActivity">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<SearchView
android:layout_width="0px"
android:layout_height="wrap_content"
android:background="#5b74a8"
android:padding="4dp"
android:id="#+id/searchView"
android:singleLine="true"
android:layout_gravity="right"
android:layout_weight="7"/>
<!--android:drawableLeft="#android:drawable/ic_menu_search"-->
<!--android:queryHint="howdy"-->
<ImageButton
android:layout_height="match_parent"
android:layout_width="wrap_content"
android:id="#+id/settingsButton"
android:background="#787878"
android:layout_gravity="center_horizontal"
android:layout_weight="1"
android:onClick="settingsPopUp"/>
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:weightSum="100">
<ListView
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="80"
android:id="#+id/contacts_list"/>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="60dp"
android:layout_weight="20"
android:orientation="horizontal" >
<CheckBox
android:layout_height="match_parent"
android:layout_width="0dp"
android:background="#ffa500"
android:text="New CheckBox"
android:id="#+id/checkBox"
android:layout_weight="1" />
</LinearLayout>
</LinearLayout>
</LinearLayout>
this is the solution.
