VisibilityPropagation

• java.lang.Object
  • TransitionPropagation

Fields Summary
private static final String	PROPNAME_VISIBILITY The property key used for {@link android.view.View#getVisibility()}.
private static final String	PROPNAME_VIEW_CENTER The property key used for the center of the View in screen coordinates. This is an int[2] with the index 0 taking the x coordinate and index 1 taking the y coordinate.
private static final String[]	VISIBILITY_PROPAGATION_VALUES

Methods Summary
public void	captureValues(TransitionValues values) View view = values.view; Integer visibility = (Integer) values.values.get(Visibility.PROPNAME_VISIBILITY); if (visibility == null) { visibility = view.getVisibility(); } values.values.put(PROPNAME_VISIBILITY, visibility); int[] loc = new int[2]; view.getLocationOnScreen(loc); loc[0] += Math.round(view.getTranslationX()); loc[0] += view.getWidth() / 2; loc[1] += Math.round(view.getTranslationY()); loc[1] += view.getHeight() / 2; values.values.put(PROPNAME_VIEW_CENTER, loc);
public java.lang.String[]	getPropagationProperties() return VISIBILITY_PROPAGATION_VALUES;
private static int	getViewCoordinate(TransitionValues values, int coordinateIndex) if (values == null) { return -1; } int[] coordinates = (int[]) values.values.get(PROPNAME_VIEW_CENTER); if (coordinates == null) { return -1; } return coordinates[coordinateIndex];
public int	getViewVisibility(TransitionValues values) Returns {@link android.view.View#getVisibility()} for the View at the time the values were captured. param values The TransitionValues captured at the start or end of the Transition. return {@link android.view.View#getVisibility()} for the View at the time the values were captured. if (values == null) { return View.GONE; } Integer visibility = (Integer) values.values.get(PROPNAME_VISIBILITY); if (visibility == null) { return View.GONE; } return visibility;
public int	getViewX(TransitionValues values) Returns the View's center x coordinate, relative to the screen, at the time the values were captured. param values The TransitionValues captured at the start or end of the Transition. return the View's center x coordinate, relative to the screen, at the time the values were captured. return getViewCoordinate(values, 0);
public int	getViewY(TransitionValues values) Returns the View's center y coordinate, relative to the screen, at the time the values were captured. param values The TransitionValues captured at the start or end of the Transition. return the View's center y coordinate, relative to the screen, at the time the values were captured. return getViewCoordinate(values, 1);
