Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.

Returns the top left coordinates of the magnifier, relative to the main application window. They will be determined by the coordinates of the last show(float, float) or show(float, float, float, float) call, adjusted to take into account any potential clamping behavior. The method can be used immediately after a #show call to find out where the magnifier will be positioned. However, the position of the magnifier will not be updated visually in the same frame, due to the async nature of the content copying and of the magnifier rendering. The method will return null if #show has not yet been called, or if the last operation performed was a #dismiss.

Mac magnifier

Returns whether the magnifier position will be adjusted such that the magnifier will be fully within the bounds of the main application window, by also avoiding any overlap with system insets (such as the one corresponding to the status bar) i.e. whether the area where the magnifier can be positioned will be clipped to the main application window and the system insets.

Shows the magnifier on the screen at a position that is independent from its content position. The first two arguments represent the coordinates of the center of the content source going to be magnified and copied to the magnifier. The last two arguments represent the coordinates of the center of the magnifier itself. All four coordinates are relative to the top left corner of the magnified view. If you consider using this method such that the offset between the source center and the magnifier center coordinates remains constant, you should consider using method show(float, float) instead.

A source bound that will extend as much as possible, while remaining within the visible region of the magnified view, as determined by View#getGlobalVisibleRect(Rect).

Returns the horizontal offset, in pixels, to be applied to the source center position to obtain the magnifier center position when show(float, float) is called. The value is ignored when show(float, float, float, float) is used instead. The units of this value are pixels.

Returns the vertical offset, in pixels, to be applied to the source center position to obtain the magnifier center position when show(float, float) is called. The value is ignored when show(float, float, float, float) is used instead. The units of this value are pixels.

A source bound that will extend as much as possible, while remaining within the visible region of the magnified view, as determined by View#getGlobalVisibleRect(Rect).

Returns the zoom to be applied to the magnified view region copied to the magnifier. If the zoom is x and the magnifier window size is (width, height), the original size of the content being magnified will be (width / x, height / x).

Windows Magnifier

Asks the magnifier to update its content. It uses the previous coordinates passed to show(float, float) or show(float, float, float, float). The method only has effect if the magnifier is currently showing.

Returns the top left coordinates of the magnifier source (i.e. the view region going to be magnified and copied to the magnifier), relative to the window or surface the content is copied from. The content will be copied: - if the magnified view is a SurfaceView, from the surface backing it - otherwise, from the surface backing the main application window, and the coordinates returned will be relative to the main application window The method will return null if #show has not yet been called, or if the last operation performed was a #dismiss.

Magnifier app

Returns the horizontal offset, in pixels, to be applied to the source center position to obtain the magnifier center position when show(float, float) is called.

Returns the vertical offset, in pixels, to be applied to the source center position to obtain the magnifier center position when show(float, float) is called.

Returns whether the magnifier position will be adjusted such that the magnifier will be fully within the bounds of the main application window, by also avoiding any overlap with system insets (such as the one corresponding to the status bar) i.e.

Shows the magnifier on the screen. The method takes the coordinates of the center of the content source going to be magnified and copied to the magnifier. The coordinates are relative to the top left corner of the magnified view. The magnifier will be positioned such that its center will be at the default offset from the center of the source. The default offset can be specified using the method Builder#setDefaultSourceToMagnifierOffset(int, int). If the offset should be different across calls to this method, you should consider to use method show(float, float, float, float) instead.

Sets the zoom to be applied to the chosen content before being copied to the magnifier popup. The change will become effective at the next #show or #update call.
