two textviews in two layouts

I want to have two relative layouts side-by-side vertically and put one text view in each layout. I want each layout to take up half of the screen (hence I used android:layout_weight="50". Here is the xml code for the main activity:
<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:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context="helloworld3.myapplication.MainActivity">
<RelativeLayout
android:id="#+id/view1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="50"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context="helloworld3.myapplication.MainActivity">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Hello World 1!" />
</RelativeLayout>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="50"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
android:layout_below="#id/view1"
tools:context="helloworld3.myapplication.MainActivity">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Hello World 2!" />
</RelativeLayout>
</RelativeLayout>
But the result displays only the first text view "Hello world 1!" and it does not display the second one, Hello world 2! Can anyone help?

Just add weight sum in parent layout and change its from Relative to Linear
layout . Also In Child layout like two relative one add layout height to
0dp below is updated code
<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="match_parent"
android:orientation="vertical"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
android:weightSum="100">
<RelativeLayout
android:id="#+id/view1"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="50"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Hello World 1!" />
</RelativeLayout>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_below="#id/view1"
android:layout_weight="50"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Hello World 2!" />
</RelativeLayout>
</LinearLayout>

If you want 2 TextViews one of top of another, taking 1/2 the screen each, just use a LinearLayout with vertical orientation:
<?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:orientation="vertical">
<TextView
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:text="Text 1"/>
<TextView
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:text="Text 2"/>
</LinearLayout>
If you do not want the TextViews to be 1/2 the height, you can wrap them in a FrameLayout:
<?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:orientation="vertical">
<FrameLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Text 1" />
</FrameLayout>
<FrameLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Text 2" />
</FrameLayout>
</LinearLayout>

Why don't you just use a horizontal linearlayout and adjust the weight to .5 for each textview and set the gravity of the textview to where you want it

Your RelativeLayout's are both set to match_parent for layout_width and layout_height
You need to set one of these to 0dp for layout_weight to have any effect. The parent should probably be changed to a LinearLayout as well. By the way layout_weight value shouldn't matter as long as they are both equal: see below
<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="match_parent"
android:orientation="horizontal"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context="helloworld3.myapplication.MainActivity">
<RelativeLayout
android:id="#+id/view1"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context="helloworld3.myapplication.MainActivity">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Hello World 1!" />
</RelativeLayout>
<RelativeLayout
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
android:layout_below="#id/view1"
tools:context="helloworld3.myapplication.MainActivity">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Hello World 2!" />
</RelativeLayout>

if you want to divide the screen half-half. you dont have to set layout_weight to 50. just set layout_height(as you want to vertically divide the screen) to 0dp, then android will do what you want without considering the RelativeLayout's height. so it could be like this:
<?xml version="1.0" encoding="utf-8"?>
<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="match_parent"
android:orientation="vertical"
tools:context="demo.drawable.propertyanimationdemo.HalfLayoutActivity">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:background="#android:color/holo_orange_light"></RelativeLayout>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:background="#android:color/holo_blue_dark"></RelativeLayout>
</LinearLayout>

use linear layout (Horizontal)
<LinearLayout
android:layout_width="match_parent"
android:weightSum="2"
android:layout_height="match_parent"
android:orientation="vertical">
<TextView
android:layout_width="match_parent"
android:layout_height="0sp"
android:layout_weight="1"
android:text="Demo 1"/>
<TextView
android:layout_width="match_parent"
android:layout_height="0sp"
android:layout_weight="1"
android:text="Demo 2"/></LinearLayout>

First off all i would suggest you to use Linear Layout for this purpose. the linear layout can easily divide the screen based on the weights given to it.
Below is a sample that will suit your problem.
<?xml version="1.0" encoding="utf-8"?>
<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="match_parent"
android:orientation="horizontal"
tools:context="helloworld3.myapplication.MainActivity">
<RelativeLayout
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1">
<TextView
android:id="#+id/textView11"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentStart="true"
android:layout_alignParentTop="true"
android:text="view 1"
android:textAppearance="?android:attr/textAppearanceMedium" />
</RelativeLayout>
<RelativeLayout
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1">
<TextView
android:id="#+id/textView12"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentStart="true"
android:layout_alignParentTop="true"
android:text="view 2"
android:textAppearance="?android:attr/textAppearanceMedium" />
</RelativeLayout>
</LinearLayout>
Apply this to your own layout and you will get what you want. do tell if it worked for you. Do accept the answer as correct answer.

LinearLayout Beneath LinearLayout full width?

I have an ImageView and a TextView that are the only items in my Android UI. Currently the TextView is in the same LinearLayout as the ImageView, so the text sometimes runs to 2 lines. I want to get the text on its own line, with the full width of the parent element so it will be the whole width of the screen. So far everything I've tried moves the ImageView outside the window or makes it very small.
<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="match_parent"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
android:weightSum="4"
android:gravity="center"
tools:context=".MainActivity"
android:baselineAligned="false">
<LinearLayout
android:layout_width="0dp"
android:orientation="vertical"
android:layout_weight="2"
android:gravity="center_vertical"
android:layout_height="wrap_content">
<ImageView
android:id="#+id/activity_main_imageview_gototags"
android:src="#drawable/img_main_gototags"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:scaleType="centerCrop"
android:onClick="imageViewGoToTagsOnClickOnClick"
android:adjustViewBounds="true"/>
<TextView
android:id="#+id/activity_main_textview_tagline"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/activity_main_textview_tagline"
android:textColor="#color/dark_blue"
android:gravity="center"
android:textSize="30sp"
android:layout_gravity="center_horizontal" />
</LinearLayout>
</LinearLayout>

May be this is what you want
<?xml version="1.0" encoding="utf-8"?>
<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="match_parent"
android:orientation="vertical"
android:gravity="center"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context=".MainActivity" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<View
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="0.5" />
<LinearLayout
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1" >
<ImageView
android:id="#+id/activity_main_imageview_gototags"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:adjustViewBounds="true"
android:onClick="imageViewGoToTagsOnClickOnClick"
android:scaleType="centerCrop"
android:src="#drawable/ic_launcher" />
</LinearLayout>
<View
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="0.5" />
</LinearLayout>
<TextView
android:id="#+id/activity_main_textview_tagline"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:maxLines="1"
android:singleLine="true"
android:gravity="center"
android:text="lfhjdhkjfhkjdhkjfhkdhkjfhdkshfkhskahdfkjdhkhkjfhdk"
android:textColor="#android:color/holo_blue_bright"
android:textSize="30sp" />
</LinearLayout>
I hope it helps.let me know if it did not.

Don't give the parent(LinearLayout) of your ImageView a width of 0dp make it match_parent instead and the same for your TextView also there's a property on text views android:maxLines that corresponds to how many lines at max can it go to, set it to 1 and if you need truncation you can also use android:ellipsize on the text view.

full width button in android layout using xml

i want to create full width button in android using xml.
here is my code
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:background="#drawable/menu"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context=".MainActivity" >
<ImageView
android:id="#+id/imageView2"
android:layout_width="180dp"
android:layout_height="180dp"
android:layout_centerHorizontal="true"
android:layout_marginTop="30dp"
android:src="#drawable/manulogo" />
<Button
android:id="#+id/button1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:drawableLeft="#android:drawable/btn_star_big_on"
android:layout_centerHorizontal="true"
android:layout_marginTop="220dp"
android:text="Drawable left"
/>
</RelativeLayout>

If you want to get rid of 16 dp margin on left and right, you will need to remove the padding properties from main relative layout.
Also, you can't use property orientation with relative layout. That's for Linear layout.
And you should use match_parent instead of fill_parent for better practice:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#drawable/menu"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context=".MainActivity" >
<ImageView
android:id="#+id/imageView2"
android:layout_width="180dp"
android:layout_height="180dp"
android:layout_centerHorizontal="true"
android:layout_marginTop="30dp"
android:src="#drawable/ic_launcher" />
<Button
android:id="#+id/button1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="220dp"
android:drawableLeft="#android:drawable/btn_star_big_on"
android:text="Drawable left" />
</RelativeLayout>
This modified code works fine.
Output:

you have do like this
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
parent layout have left and right padding so remove it and Button will be full screen
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#drawable/menu"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context=".MainActivity" >
<ImageView
android:id="#+id/imageView2"
android:layout_width="180dp"
android:layout_height="180dp"
android:layout_centerHorizontal="true"
android:layout_marginTop="30dp"
android:src="#drawable/manulogo" />
<Button
android:id="#+id/button1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:drawableLeft="#android:drawable/btn_star_big_on"
android:layout_centerHorizontal="true"
android:layout_marginTop="220dp"
android:text="Drawable left"
/>
</RelativeLayout>

TextView does not fit the screen

I have an activity with a TextView. I would like to align it on the bottom of the screen, in the center and I would like that the TextView fits the screen's width.
This is my XML:
<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:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
android:background="#ffffff"
tools:context=".ShowCard" >
<TextView
android:id="#+id/textView"
android:layout_alignParentBottom="true"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:background="#33000000"
android:textColor="#000000"
android:text="#string/lorem_ipsum" />
The result is not what I have expected to see. The TextView is not full-screen in the width, but leaves a small free space right and left (like padding/border, but I've not set padding/border!).
Do you know why? Suggestions?

try 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" >
<TextView
android:id="#+id/textView"
android:layout_alignParentBottom="true"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:background="#33000000"
android:textColor="#000000"
android:text="#string/lorem_ipsum" />
</RelativeLayout>

Excuse me, I'm a stupid guy!
I've not see that in the container XML code were included four padding rows:
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
I've deleted these rows and now everything is working correctly!
Sorry.

<TextView
android:id="#+id/textView"
android:layout_alignParentBottom="true"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:background="#33000000"
android:textColor="#000000"
android:text="#string/lorem_ipsum" />
Use the 'fill_parent' attribute, it should fill the entire width of the screen.

remove
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
from the parent relative layout.

<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"

<TextView
android:id="#+id/textView"
android:layout_alignParentBottom="true"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:background="#33000000"
android:textColor="#000000"
android:text="#string/lorem_ipsum" />
use this

stick LinearLayour ( horizontal ) to the buttom without any space

Sorry, i've completed my question very much, so I reasked that and deleted prev post...
I'm using LinearLayout ( with 4 ImageButtons in a raw ) in a RelativeLayout in my project and I have used android:layout_alignParentBottom="true" for it ( linear ) to stick to the buttom of RelativeLayout, but my problem is the space between LinearLayout's ImageButtons and the corners of the screen. I want to remove them to make my ImageButtons be like a menu bar on the bottom of the screen. Is it possible for anyone to help me please ? THANK YOU ! :)

Remove the padding on your RelativeLAyout
From:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"
android:layout_height="match_parent"
