you are using orentation verticle and weight property so u have give
android:layout_height="0dp"
insted
android:layout_height="wrap_content"
for ue child linear laouts only which are considered in verticle
hope it works for u..

use scrollView for the parent layout
Why are you using "sp" sp is more suitable for text, try using dp

Set a LinearLayout to scroll

I have been reading many posts here in stackoverflow about making a linear layout scroll and have applied all the specific advices to make it work but it still does not show on the left hand side. I am new to android and not sure what i am doing wrong.

use this :

and set hieght to
android:layout_height="wrap_content"

similarly for 3rd,4rth,5th sub layouts and so on........

Make the child of the ScrollView have android:layout_height="wrap_content" (currently yours has match_parent)

add
android:layout_width="match_parent"
android:layout_height="match_parent"
to your root ScrollView

I hope this code may be help you.
android:layout_width="match_parent"
android:layout_height="match_parent">

Setting width ratio in relative layout

Im pretty new to Android Layouts.
Im trying to set Age:EditText:Year in ratio 1:3:1 and same size on Height.
Should I use TableLayout? If yes how can i prevent TableRow1 from changing width etc when I do some stuff in other rows?

I think this is what you want. see image below.
<?xml version="1.0" encoding="utf-8"?>

I think you should use linear layout.you can set android:weightSum="10" properties.
Its total layout. now you have to set for chilled object using android:layout_weight="2".
So that will control your object in layout.
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:layout_marginLeft="5dp"
android:layout_weight="2"
android:text="Age" />
<EditText
android:id="#+id/editText1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="6" >
</EditText>
<TextView
android:id="#+id/textView1"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:layout_marginRight="5dp"
android:layout_weight="2"
android:text="Years" />

Have something like this.. Pseudo code untested..
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/relative_layout"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<LinearLayout
android:gravity = "center_horizontal"
android:id="#+id/firstLinearLayout"
android:orientation = "horizontal"

android:gravity="bottom"
add this line to both your vertical as well as horizontal linear layout
I guess this was the answer you were looking for

Replace with following code
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<LinearLayout
android:id="#+id/btnLayout"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_above="#+id/progressbar_Horizontal"
>
<Button
android:id="#+id/play"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
<Button
android:id="#+id/pause"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<Button
android:id="#+id/back"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<Button
android:id="#+id/fwd"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
<ProgressBar
android:layout_width="fill_parent"
android:layout_height="wrap_content"
style="?android:attr/progressBarStyleHorizontal"
android:id="#+id/progressbar_Horizontal"
android:layout_alignParentBottom="true"
/>

Basic Scolling Question

Hey guys, im pretty new to android platform and have a really simple question. Im putting buttons as layouts with text boxes, but im running out of room. How would i make it possible for the user to scroll down to view more buttons and stuff. For example, if i have 6 buttons, and 3 are in the field of view, i wanna be able to scroll with my finger and be able to see those buttons as I scroll.
Thanks for the help guys

You can put your controls(widgets: buttons, labels etc) inside a ScrollView. Check the documentation of the class for details : http://developer.android.com/reference/android/widget/ScrollView.html
Something like:
<ScrollView ..>
<TextView .../>
<Button .../>
</ScrollView>

Try this:
<?xml version="1.0" encoding="utf-8"?>
