title: Unwanted space between two ImageView on android
body: <p>Im using this Layout to put two ImageViews one next to the other, but the two images seems to be separated by 1 transparent pixel space.<br>
  The blue background is there to make easier to observe the problem...<br><br></p>
  
  <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt;
  &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
      android:orientation="vertical"
      android:layout_width="fill_parent"
      android:layout_height="fill_parent"
      android:background="#0000FF"&gt;
      &lt;LinearLayout
          android:orientation="horizontal"
          android:layout_width="fill_parent"
          android:layout_height="wrap_content"
          android:gravity="center"
          android:layout_marginTop="5dip"&gt;
          &lt;ImageView
              android:src="@drawable/i_position_icon"
              android:layout_width="wrap_content"
              android:layout_height="wrap_content"/&gt;
          &lt;ImageView
              android:src="@drawable/i_position_seekbar"
              android:layout_width="wrap_content"
              android:layout_height="wrap_content"/&gt;
      &lt;/LinearLayout&gt;
  &lt;/LinearLayout&gt;
  </code></pre>
  
  <p>The .java is:</p>
  
  <pre><code>public class MainActivity extends Activity {
  
      /** Called when the activity is first created. */
      @Override
      public void onCreate(Bundle icicle) {
          super.onCreate(icicle);
          requestWindowFeature(Window.FEATURE_NO_TITLE);
          getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
          setContentView(R.layout.main);
  
      }
  }
  </code></pre>

  Im using a device with android 2.2.<br>
  I wasnt able to reproduce the glitch on a 2.1-update1 emulator neither on a 1.6 emulator... <br>
  Ive checked the images and they have no extra pixels arround them.<br>
  Also i tried adding a red 1px width border on the images separately and the glitch is still there, so the images dont seem to be the problem.<br><br>
  These are the problematic images (correctly shown here):<br>
