TextView font size color layout interface andoid exam

I created a new Android Project in Eclipse called “AndroidFonts”:

From here I modified the “main.xml” file in the layout folder.

<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"     android:orientation="vertical"     android:layout_width="fill_parent"     android:layout_height="fill_parent"     >     <TextView         android:orientation="horizontal"         android:layout_width="fill_parent"         android:layout_height="wrap_content"         android:text="MonoSpace Font:"         android:textSize="16sp"         android:paddingLeft="5sp"         />     <TextView         android:orientation="horizontal"         android:layout_width="fill_parent"         android:layout_height="wrap_content"         android:paddingLeft="5sp"         android:typeface="monospace"         android:text="Hello Red Monospace"         android:textSize="16sp"         android:textColor="#ff0000"         />     <TextView         android:orientation="horizontal"         android:layout_width="fill_parent"         android:layout_height="wrap_content"         android:text="Sans Font:"         android:textSize="16sp"         android:paddingLeft="5sp"         />     <TextView         android:orientation="horizontal"         android:layout_width="fill_parent"         android:layout_height="wrap_content"         android:paddingLeft="5sp"         android:typeface="sans"         android:text="Hello Blue Sans"         android:textSize="16sp"         android:textColor="#0000ff"         />     <TextView         android:orientation="horizontal"         android:layout_width="fill_parent"         android:layout_height="wrap_content"         android:text="Serif Font:"         android:textSize="16sp"         android:paddingLeft="5sp"         />     <TextView         android:orientation="horizontal"         android:layout_width="fill_parent"         android:layout_height="wrap_content"         android:paddingLeft="5sp"         android:paddingRight="2sp"         android:typeface="serif"         android:text="Hello Green Serif"         android:textSize="16sp"         android:textColor="#00ff00"         />     <TextView         android:orientation="horizontal"         android:layout_width="fill_parent"         android:layout_height="wrap_content"         android:paddingLeft="5sp"         android:paddingTop="15sp"         android:typeface="normal"         android:text="I'm normal font but I'm also bold and italic"         android:textSize="16sp"         android:textStyle="bold|italic"         android:textColor="#ffffff"         />     <TextView         android:orientation="horizontal"         android:layout_width="fill_parent"         android:layout_height="wrap_content"         android:paddingLeft="5sp"         android:paddingTop="15sp"         android:paddingBottom="15sp"         android:typeface="normal"         android:text="I'm normal (bold) font but I have a shadow"         android:textSize="16sp"         android:textStyle="bold"         android:shadowColor ="#0f0f0f"         android:shadowRadius="1.6"         android:shadowDx="1.5"         android:shadowDy="1.3"         android:textColor="#000000"         android:background="#ffffff"         /> </LinearLayout>

When I run the project I get this result in the emulator:

As you can see from the code I used the fonts: sans, serif, and monospace. Then I showed off how to make a string bold and italic:

android:textStyle="bold|italic"

Then a string utilizing the shadowing effect:

android:shadowColor ="#0f0f0f" android:shadowRadius="1.6" android:shadowDx="1.5" android:shadowDy="1.3"

Colors are as simple as adding:

android:textColor="#ff0000"

Pretty easy!
