getDISABLED_ACTIONMODE_CALLBACK

@NotNull
public android.view.ActionMode.Callback getDISABLED_ACTIONMODE_CALLBACK()

Use this ActionMode.Callback if action mode should be disabled

setDISABLED_ACTIONMODE_CALLBACK

public void setDISABLED_ACTIONMODE_CALLBACK(@NotNull

saveViewTransformation

public void saveViewTransformation(@NotNull
                                   android.view.View view)

Saves View transformation parameters (translation, imageScale, rotation, alpha), so they can later be restored with .restoreViewTransformation. Note, that this implementation uses View.setTag method to save parameters, so any existing tags will be overwritten.

See Also:

.restoreViewTransformation

restoreViewTransformation

public void restoreViewTransformation(@NotNull
                                      android.view.View view)

Restores transformation values.

Throws:

IllegalStateException - if values were corrupted (by direct invocation of View.setTag)

postOnPreDraw

public void postOnPreDraw(@NotNull
                          android.view.View view,
                          @NotNull
                          java.lang.Runnable runnable)

Executes Runnable right before global draw event, which is convenient if you want to be sure that provided View correctly calculated it's size.

Parameters:

view -

runnable -

getViewBounds

@NotNull
public android.graphics.Rect getViewBounds(@NotNull
                                                    android.view.View view)

Returns:

                             float rotation)

Convenient alternative for .fitRectToView which creates rectangle from Bitmap
