You can set a shape as the background of a layout. ex shape
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<stroke android:width="4dp" android:color="#FF00FF00" />
<padding android:left="7dp" android:top="7dp"

You can use the base color from Android
<TextView android:id="@+id/textViewId"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@android:color/white"
android:text="@string/hello"
/>
But again you have only limited colors. You can check them out by doing
android.R.color.
Then eclipse will prompt what is out there. the set is very small. This could be useful to quickly try somethign. Otherwise you will need your own color set
satya - Monday, January 31, 2011 6:53:26 PM
Here is a way to control the text size
<TextView android:id="@+id/textViewId"
....
android:textSize="@dimen/medium_size"
...
/>
satya - Monday, January 31, 2011 6:53:59 PM
Defining the dimension above
<resources>
<string name="hello">Hello World</string>
<dimen name="forty_pixels">40px</dimen>
<dimen name="medium_size">100sp</dimen>
</resources>

Note on layoutparams
The dimension can be one of
?FILL_PARENT (renamed MATCH_PARENT in API Level 8 and higher), which means that the view wants to be as big as its parent (minus padding)
?WRAP_CONTENT, which means that the view wants to be just big enough to enclose its content (plus padding)
?an exact number

layout weight and gravity are properties of LinearLayout
gravity indicates alignment
weight Indicates how much of the extra space in the LinearLayout will be allocated to the view associated with these LayoutParams.
satya - Friday, February 11, 2011 1:05:46 PM
More on layout_weight
Indicates how much of the extra space in the LinearLayout will be allocated to the view associated with these LayoutParams. Specify 0 if the view should not be stretched. Otherwise the extra pixels will be pro-rated among all views whose weight is greater than 0.

B2 above needs to aligned to right and it is sufficient...
to say B1 is just left of B2. You dont need to say B1 is also aligned to the parent right. If you say it B1 and B2 will be overlapped.

I suppose you could do this for varying the textsize for contrast
android:textSize="@android:style/TextAppearance.Small"
satya - 3/17/2013 9:22:53 AM
That would be wrong: textSize can be only a dimension

sp and dp
when you specify size in "dp" or "dip" (density independent pixels), Android will adjust the scaling to keep the size relatively the same. This means in a high density device it will take more pixels.
On the same device an "sp" (scalable pixels) will adjust to the level of magnification that the user wants.
Typically scalable graphics like "Text" uses "sp" as it won't loose clarity when scaled up or down.

You may want to lead your layout files like this
<?xml version="1.0" encoding="utf-8"?>
<!--
*********************************************
* create_word_meaning.xml
* prefix: cwm_
* Create a word meaning
* Input controls:
* word
* details: created by, on
* meaning text area
* submit button
*********************************************
-->
The prefix will let you prefix your ids so that they don't conflict in the R.id namespace!!
satya - 4/10/2013 9:49:48 AM
Correspondingly in your activity top do this
/*
* Given a word create a meaning for it.
* uses layout: create_word_meaning (cwm_)
*/
