Class ZoomageView

java.lang.Object

android.view.View

android.widget.ImageView

android.support.v7.widget.AppCompatImageView

com.jsibbold.zoomage.ZoomageView

All Implemented Interfaces:

Drawable.Callback, TintableBackgroundView, AccessibilityEventSource, KeyEvent.Callback, ScaleGestureDetector.OnScaleGestureListener

public class ZoomageView
extends AppCompatImageView
implements ScaleGestureDetector.OnScaleGestureListener

ZoomageView is a pinch-to-zoom extension of ImageView, providing a smooth user experience and a very natural feel when zooming and translating. It also supports automatic resetting, and allows for exterior bounds restriction to keep the image within visible window.

                   int defStyle)

Method Detail

setScaleRange

public void setScaleRange(float minScale,
                          float maxScale)

Set the minimum and maximum allowed scale for zooming. minScale cannot be greater than maxScale and neither can be 0 or less. This will result in an IllegalStateException.

Parameters:

minScale - minimum allowed scale

maxScale - maximum allowed scale

isTranslatable

public boolean isTranslatable()

Returns whether the image is translatable.

Returns:

true if translation of image is allowed, false otherwise

setTranslatable

public void setTranslatable(boolean translatable)

Set the image's translatable state.

Parameters:

translatable - true to enable translation, false to disable it

isZoomable

public boolean isZoomable()

Returns the zoomable state of the image.

Returns:

true if pinch-zooming of the image is allowed, false otherwise.

setZoomable

public void setZoomable(boolean zoomable)

Set the zoomable state of the image.

Parameters:

zoomable - true to enable pinch-zooming of the image, false to disable it

getRestrictBounds

public boolean getRestrictBounds()

If restricted bounds are enabled, the image will not be allowed to translate farther inward than the edges of the view's bounds, unless the corresponding dimension (width or height) is smaller than those of the view's frame.

Returns:

true if image bounds are restricted to the view's edges, false otherwise

setRestrictBounds

public void setRestrictBounds(boolean restrictBounds)

Set the restrictBounds status of the image. If restricted bounds are enabled, the image will not be allowed to translate farther inward than the edges of the view's bounds, unless the corresponding dimension (width or height) is smaller than those of the view's frame.

Parameters:

restrictBounds - true if image bounds should be restricted to the view's edges, false otherwise

getAnimateOnReset

public boolean getAnimateOnReset()

Returns status of animateOnReset. This causes the image to smoothly animate back to its start position when reset. Default value is true.

Returns:

true if animateOnReset is enabled, false otherwise

Set whether or not the image should animate when resetting.

Parameters:

animateOnReset - true if image should animate when resetting, false to snap

getAutoResetMode

Get the current AutoResetMode mode of the image. Default value is AutoResetMode.UNDER.

Returns:

the current AutoResetMode mode, one of OVER, UNDER, ALWAYS, or NEVER

setAutoResetMode

public void setAutoResetMode(int autoReset)

Set the AutoResetMode mode for the image.

Parameters:

autoReset - the desired mode, one of OVER, UNDER, ALWAYS, or NEVER

getAutoCenter

public boolean getAutoCenter()

Whether or not the image should automatically center itself when it's dragged partially or fully out of view.

Returns:

true if image should center itself automatically, false if it should not

setAutoCenter

Set whether or not the image should automatically center itself when it's dragged partially or fully out of view.

Parameters:

autoCenter - true if image should center itself automatically, false if it should not

Overrides:

setScaleType in class ImageView

setEnabled

public void setEnabled(boolean enabled)

Set enabled state of the view. Note that this will reset the image's ImageView.ScaleType to its pre-zoom state.

Overrides:

setEnabled in class View

Parameters:

enabled - enabled state

onTouchEvent

public boolean onTouchEvent(MotionEvent event)

Overrides:

onTouchEvent in class View

reset

public void reset()

Reset image back to its original size. Will snap back to original size if animation on reset is disabled via setAnimateOnReset(boolean).

reset

public void reset(boolean animate)

Reset image back to its starting size. If animate is false, image will snap back to its original size.

Parameters:

animate - animate the image back to its starting size

onScale
