title: Android : Find Angle, and draw Bitmap at that angle?
body: <p>I am porting a game I have made, from Windows (Visual Studio c# XNA4) to Android.</p>
  
  <p>In the game, I need to find the location of the users "touch" (Which I have done), and then "point" the player to this touch location (draw the player bitmap at this angle). </p>
  
  <p>In c# and XNA4, I used the following: </p>
  
  <pre><code>Matrix rotationMatrix = Matrix.CreateRotationZ(playerAngle);
  PlayerDirection = Vector2.Transform(up, rotationMatrix); 
  </code></pre>
  
  <p>If the players position was</p>
  
  <pre><code>x = 200;
  y = 200; 
  </code></pre>
  
  <p>And the touch co-ordinates were</p>
  
  <pre><code>x = 300;
  y = 300;
  </code></pre>
  
  <p>How would I make the player "point" at where the user touched?</p>
