title: How come the Android soft keyboard is not responding to EditText?
body: <p>I have a SherlockFragmentActivity and a SherlockFragment that is within a TabManager.  In this Fragment I have RadioButtons, CheckBoxes, a Button and an EditText in a LinearLayout.  The keyboard sometimes does not respond when pressing on the EditText.  </p>
  
  <p>In a 2.1 AVD the keyboard responds inconsistently, in a 4.0 AVD the keyboard does not respond at all, and on a device the keyboard responds inconsistently.  Sometimes pressing the other objects then activates the ability to show the keyboard.</p>
  
  <p>Here is the XML for the EditText:</p>
  
  <pre><code>    &lt;EditText       android:id="@+id/EditText1"
                      android:layout_width="100dp"
                      android:layout_height="wrap_content"
                      android:inputType="number"
                      android:text="20" &gt;
  </code></pre>
  
  <p>I'm confused of the inconsistent activity more so than the fact that it doesn't work on the 4.0 AVD.  Any suggestions to why this is happening or a way to show the keyboard would be great.</p>
