Activity seems to be transparent but it is not - android

I have created an activity following some tutorials on SO.Activity is transparent with respect to the background color of another activity but it is not showing transparency with the text contained by the background activity.
XML:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:background="#color/ApplicationForeground"
android:gravity="center_vertical"
android:orientation="vertical" >
ApplicationForeground is blue which I set purposefully.
layoutrater is also not showing any text contained by background activity.
<LinearLayout
android:id="#+id/layoutRater"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:alpha="1"
android:background="#color/opakkblackeighty"
android:gravity="center"
android:orientation="horizontal"
>
opakkblackeighty is set #40000000.
This textview should show its context and the text contained by background activity.
<TextView
android:id="#+id/downVote"
android:layout_width="100sp"
android:layout_height="100sp"
android:layout_marginLeft="5sp"
android:layout_marginRight="5dp"
android:layout_marginTop="5sp"
android:background="#color/opakkblackeighty"
android:gravity="center"
android:src="#drawable/downvote"
android:text="-"
android:textColor="#color/ApplicationForeground"
android:textSize="50sp" />
</LinearLayout>
<TextView
android:id="#+id/totalVoting"
android:layout_width="fill_parent"
android:layout_height="30dp"
android:background="#color/opakkblackeighty"
android:gravity="center"
android:text="0"
android:textColor="#android:color/holo_green_light"
android:textSize="20sp" />
</LinearLayout>

The linearlayout is filling parent, so you dont see the activity background.

How to set textView as right as possible and set textView show only a part of text?

I have the xml code shown below. Everything is working as it should except the final textView( id locationTextView) which won't stay right. I want it to stay as right as possible, but I can't do that(it still appears straight after the linear Layout).Should I set a left margin?. And for the textView1 how can I make it to show only a certain part of the whole text, because I have texts of different lengths and they ruin the layout.

Try android:layout_weight="1" or some other value for your locationTextView. You can also try out android:weightSum="3" (or that is appropriate instead of 3) on your root LinearLayout. Assign proper weights to your different child views. You can get help here
For showing text in a presentable way, you could use android:ellipsize="marquee" or other options available.

RelativeLayout doesn't match parent's height

The relativelayout inside main layout won't fill the parent height when it's displayed on device. In fact i want the left-side layout with the yellow color to fill the row vertically.
here is the xml code:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/verses_relativeLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<com.ad.holyquran.extra.TextViewEx
android:id="#+id/textView_Verse"
android:layout_width="wrap_content"

android:layout_alignParentRight="true"
android:layout_toRightOf="#+id/versesRelativeLayout"
android:gravity="right"
android:layout_marginTop="-15dp"
android:paddingBottom="5dp"

Thanks for reading.
If you remove the line
android:layout_toRightOf="#+id/versesRelativeLayout"
It will stop being on the right. If you need the yellow as background, then in the main layout (which is the first relativeLayout) set it as the background using
android:background="#drawable\image"
You may need to put all the other elements inside the main RelativeLayout.
Hope this helps.
I couldn't see the end tag of the main RelativeLayout.
Just add the tag in layout versesRelativeLayout:
android:layout_alignBottom="#+id/textView_VerseTranslation"
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:id="#+id/versesRelativeLayout"
android:layout_alignParentLeft="true"
android:background="#fff3f27f"
android:layout_alignParentTop="false"
android:layout_alignParentBottom="false"
android:layout_alignBottom="#+id/textView_VerseTranslation"

Android text will not align to center

I have a TextView and 3 Buttons centered in a RelativeLayout, and the text in all three of them is left-justified with the parent center as the leftmost line.
I've tried changing the gravity of the TextView, Buttons, and layout but nothing is working and I'm baffled because I've never seen Android align text like this before.
I want the Button text to be centered within each Button and the top text to be center-justified.
An image of what it looks like is here: http://i.stack.imgur.com/9lHEd.png
Here's 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" >
<TextView
android:id="#+id/textView1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_margin="20dp"
android:gravity="center_horizontal"
android:text="#string/greeting"
android:textAppearance="?android:attr/textAppearanceLarge" />
<Button
android:id="#+id/startQuizButton"
android:layout_width="280dp"
android:layout_height="wrap_content"
android:layout_below="#+id/textView1"
android:layout_centerHorizontal="true"
android:onClick="#string/startQuiz"
android:text="#string/start_quiz" />
<Button
android:id="#+id/lessonsButton"
android:layout_width="280dp"
android:layout_height="wrap_content"
android:layout_below="#+id/startQuizButton"
android:layout_centerHorizontal="true"
android:onClick="#string/startLesson"
android:text="#string/lessonsString" />
<Button
android:id="#+id/viewAllButton"
android:layout_width="280dp"
android:layout_height="wrap_content"
android:layout_below="#+id/lessonsButton"
android:layout_centerHorizontal="true"
android:onClick="#string/showAll"
android:text="#string/view_all" />
I included a RelativeLayout because you have it as your parent layout. However, i am not sure that it is needed. See if the following code is what you are looking for.
<?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:orientation="vertical" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:text="Greetings" />
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Start Quiz" />
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Lessons" />
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="View all questions" />
</LinearLayout>
</RelativeLayout>
add in button tab android:gravity="center"...see if it works..
u need to set layout width and height to fill_parent and everything will work fine
<TextView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="center"
android:text="your text" />
if you want to centre some text, then you could also do it this way:
<TextView
android:text="Quantity"
android:textSize="34sp"
android:textColor="#ffffff"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:fontFamily="sans-serif-light"
android:layout_centerHorizontal="true"
android:paddingTop="10dp"/>
here i have changed made it horozontal by using android:layout_centerHorizontal="true"which takes a boolean value of true or false, by making it true, it will automatically be centred on all devices
hope that helps

i think that scroll will be set on above xml means on "listplacehold.xml" but how?,when i am doing it is set to for half screen,means it is not displaying in whole view... Thanks for help in advance.
don't use the ScrollView with the combination of the ListView. Instead make your layout like this.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#1A77BD" >
<Button
android:id="#+id/lodmore"
android:text="Load More..."
android:textColor="#color/white"
android:id="#+id/keywordsearchbutton"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true""
android:drawableLeft="#drawable/load_more_off"
android:gravity="left|center_vertical"
android:background="#1A77BD"/>
<View
android:id="#+id/horizontolline"
android:layout_width="fill_parent"
android:layout_height="1dip"
android:layout_above="#id/loadmore"
android:background="#000000"/>
<ListView
android:id="#+id/android:list"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:layout_alignParentTop="true"
android:layout_above="#id/horizontolline/>
</RelativeLayout>
put scrollview over your root layout and remember only one layout node is allowed under scrollview.....
