title: auto adjust the size and position of edittext and button
body: <p>In emulator, size of edittext and button looks nice but in motorola milestones, both of them are so small. I think there are different types of screen layout. Is it possible to adjust the size automatically? My xml is below :</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;&lt;RelativeLayout
  android:layout_width="fill_parent"
  android:layout_height="fill_parent"
  xmlns:android="http://schemas.android.com/apk/res/android"&gt;
  &lt;EditText android:id="@+id/txtToText_e" 
   android:layout_width="270px" 
   android:layout_height="wrap_content" 
   android:textSize="18sp" 
   android:hint="Type To Compose" 
   android:layout_alignParentBottom = "true"
   android:layout_alignParentLeft="true"/&gt;   &lt;Button android:text="Send" 
   android:id="@+id/btnDone_e" 
   android:layout_width="85px" 
   android:layout_height="wrap_content"      
   android:layout_alignParentBottom = "true"
   android:layout_alignParentRight="true"/&gt;                                 
  </code></pre>
  
  <p></p>
  
  <p>To get the auto re-sized edittext while turning the phone from portrait to landscape, i add these xml code in AndroidManifest.xml</p>
  
  <pre><code>    &lt;supports-screens android:smallScreens="true"
                android:normalScreens="true"
                android:largeScreens="true"
                android:anyDensity="true" /&gt;
  </code></pre>
  
  <p>But nothing change =[. how to fix it?</p>
  
  <p>Thank you.</p>
