  <pre><code>&lt;?xml version="1.0" encoding="utf-8" ?&gt;
  
  &lt;LinearLayout
      xmlns:android="http://schemas.android.com/apk/res/android"
      android:id="@+id/rotate_test_layout"
      android:layout_width="fill_parent"
      android:layout_height="fill_parent" &gt;
  
      &lt;ImageView
          android:id="@+id/android"
          android:src="@drawable/android"
          android:layout_width="fill_parent"
          android:layout_height="fill_parent"
          android:layout_gravity="center"
          android:scaleType="matrix"
          android:adjustViewBounds="true"
          android:contentDescription="@string/android_description" &gt;
      &lt;/ImageView&gt;
  
  &lt;/LinearLayout&gt;
  </code></pre>
  
  <p>Activity file:</p>
  
  <pre><code>public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.rotate_test_layout);
      ImageView imageView = (ImageView)findViewById(R.id.android);
      imageView.setScaleType(ScaleType.MATRIX);
      Matrix matrix = new Matrix();
      matrix.postRotate(90);
      imageView.setImageMatrix(matrix);
  }
  </code></pre>
