Try this Layout. I have applied some changes to your Layout. I have remove child Linear Layout because it is useless or android:layout_alignParentRight="true" will not get affected. Also added Relative Layout as your Root Layout.

Linear Layout has no such attribute to set Right:
So you have to add the view with weight which will coverup the middle blank space.

android:padding="5dp">

Between the two RelativeLayout, insert a third View:
<View
android:layout_width="0dp"
android:layout_height="0dp"
android:layout_weight="1" />
Because of it's layout weight, this will "push" your second RelativeLayout to the right side.

In order to use android:layout_alignParentRight="true", the parent should be RelativeLayout. The parent of your RelativeLayout is LinearLayout and if I'm not mistaken, you want that RelativeLayout to be at the right of parent. Either make the parent RelativeLayout, or give weight_sum to LinearLayout and weight to the children.

Try it in second RelativeLayout
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="right"
android:layout_marginRight="0dp"
android:background="#android:color/holo_red_light">
android:layout_alignParentRight attribute only work in children of RelativeLayout. Now, you are using it in a child of a LinearLayout so it will not work.

You have few ways to do what you require. Ill give you 2.
First you can change the "Parent Layout" to Relative and add alignParentRight="true" and alignParentLeft="true" for the two LinearLayout.
Second, with the way you did it, you can change to width of the two LinearLayout to 0dp and then, add them layout_weight="1".

Try this code ::

Android : How do I put my text at the bottom?

I want my text to stay at bottom for each screen size. I've tried using margintop and added a blank in the middle to push the TextView to the bottom but it does not work on other screens. This is my code and screen.

use weight = 0 for the textview, or use a RelativeLayout parent and make your textview alightParentBottom="true"

Try this..

No resource identifier found for attribute 'layout_alignParentCenter' in package 'android'

I'm getting two errors when attempting to add a scrollable navigation bar to the bottom of my screen. I've never seen this error before and the answers I've found thus far do not seem to resolve the issue I'm having.
ERRORS:
error: No resource identifier found for attribute 'layout_alignParentCenter' in package 'android' home.xml /idg/res/layout line 298 Android AAPT Problem
error: No resource identifier found for attribute 'layout_alignParentCenter' in package 'android' home.xml /idg/res/layout line 361 Android AAPT Problem
Any input is greatly appreciated.

There is no such layout attribute in LinearLayout nor RelativeLayout.
For LinearLayout, you need to use android:gravity="center".
For RelativeLayout, you need to set android:layout_centerInParent to true.
For the linear layout, you need to make sure your view is assigned enough room (via its layout_width/height and/or via layout_gravity) so that it makes sense to render its contents centered. For RelativeLayout, the container must be large enough so that it makes sense to center the view inside it.

How to implement this type of layout

In my application, i want the layout like in the image below.
I have been trying this for hours but could not get the desired results.
Here is my layout xml:
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingTop="#dimen/activity_vertical_margin" >
<View
android:id="#+id/middleSeperator"
android:layout_width="1dp"
android:layout_height="fill_parent"
android:layout_alignParentTop="true"
android:background="#90909090" />
<LinearLayout
android:id="#+id/leftLayout"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_toLeftOf="#id/middleSeperator"
android:gravity="right"
android:orientation="vertical" >
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"

With this, left side textviews are not visible. Please Help.

You can do this in many ways, one can be using plain LinearLayout as container, then set your both TextViews width to fill_parent AND set android:layout_weight="1" on both TextViews so they take 50% of the available width. And then you need to put the vertical line in between with fixed size like 1dp (you can put ImageView or even empty FrameLayout with background color).

try this .
1-You can create the parent layout Horizontal
which will arrange all item horizontally .
2- Inner layout make it vertically
3- Add View
4-Inner layout make it vertically.
This is simple and change it according to your need ,i just created for demo.
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical" >
<TextView
android:id="#+id/textViewStatus"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="abc" />
<TextView
android:id="#+id/textViewStatus"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
