i want to rotate and scale the image on multi touch event, i am able to drag, scale the image but i can't understand the rotation of image. i am facing problem so please help me asap. my code is there public class Touch extends Activity implements OnTouchListener { private static final String TAG = "Touch"; // These matrices will be used to move and zoom image Matrix matrix = new Matrix(); Matrix matrix1 = new Matrix(); Matrix savedMatrix = new Matrix(); Matrix savedMatrix2 = new Matrix(); // We can be in one of these 3 states static final int NONE = 0; static final int DRAG = 1; static final int ZOOM = 2; int mode = NONE; float oldscale =0; // Remember some things for zooming PointF start = new PointF(); PointF mid = new PointF(); float oldDist = 1f; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); ImageView view = (ImageView) findViewById(R.id.imageView2); view.setOnTouchListener(this); ImageView view1 = (ImageView) findViewById(R.id.imageView2); view1.setOnTouchListener(this); // ... // Work around a Cupcake bug matrix.setTranslate(1f, 1f); matrix1.setTranslate(1f, 1f); view.setImageMatrix(matrix); view1.setImageMatrix(matrix1); } @Override public boolean onTouch(View v, MotionEvent rawEvent) { WrapMotionEvent event = WrapMotionEvent.wrap(rawEvent); // ... ImageView view = (ImageView) v; // Dump touch event to log dumpEvent(event); // Handle touch events here... double r = Math.atan2(event.getX() - 400 / 2, 400 / 2 - event.getY()); int rotation = (int) Math.toDegrees(r); float newRot = new Float(rotation); switch (event.getAction() & MotionEvent.ACTION_MASK) { case MotionEvent.ACTION_DOWN: savedMatrix.set(matrix);
