Android: TouchImageView Created by: Mike Ortiz Contributions by: * Patrick Lackemacher * Babay88 * @ipsilondev Date: 2/17/2012 ---------------------- Adds panning, pinch zoom, double tap zoom, and fling to Android ImageView. Usage: ---------------------- Place TouchImageView.java in your project. It can then be used the same as ImageView. Example: TouchImageView img = (TouchImageView) findViewById(R.id.img); If you are using TouchImageView in xml, then you must provide the full package name, because it is a custom view. Example: <com.example.touch.TouchImageView android:id="@+id/img” android:layout_width="match_parent" android:layout_height="match_parent" /> API: ---------------------- // Get the current zoom. This is the zoom relative to the initial // scale, not the original resource. float getCurrentZoom(); // For a given point on the view (ie, a touch event), returns the // point relative to the original drawable's coordinate system. PointF getDrawablePointFromTouchPoint(float x, float y); // For a given point on the view (ie, a touch event), returns the // point relative to the original drawable's coordinate system. PointF getDrawablePointFromTouchPoint(PointF p); // Get the max zoom multiplier. float getMaxZoom(); // Get the min zoom multiplier. float getMinZoom(); // After setting image, a value of true means the new image should maintain // the zoom of the previous image. False means the image should be resized // within the view. Default value is true. void maintainZoomAfterSetImage(boolean maintainZoom); // Set the max zoom multiplier. Default value: 3. void setMaxZoom(float max); // Set the min zoom multiplier. Default value: 1. void setMinZoom(float min);
