Method Detail

• getFillScaleWithBufferAspectRatio

   final static Pair<Float, Float> getFillScaleWithBufferAspectRatio(View container, View view, Size bufferSize)

  Computes the scale by which a view has to scale in x and y in order to fill its parent while maintaining the buffer's aspect ratio.

  Parameters:

  container - A parent android.view.View that wraps view.

  view - A child android.view.View of container.

  bufferSize - A android.util.Size whose aspect ratio must be maintained when scaling view inside its parent container.

• getFitScaleWithBufferAspectRatio

   final static Pair<Float, Float> getFitScaleWithBufferAspectRatio(View container, View view, Size bufferSize)

  Computes the scale by which a view has to scale in x and y in order to fit its parent while maintaining the buffer's aspect ratio.

  Parameters:

  container - A parent android.view.View that wraps view.

  view - A child android.view.View of container.

  bufferSize - A android.util.Size whose aspect ratio must be maintained when scaling view inside its parent container.

• getOriginOfCenteredView

   final static Point getOriginOfCenteredView(View container, View view)

  Computes the top left coordinates for the view to be centered inside its parent.

  Parameters:

  container - A parent android.view.View that wraps view.

  view - A child android.view.View of container.

• getRotationDegrees

   final static Integer getRotationDegrees(View view)

  Computes the rotation of a android.view.View in degrees from its natural orientation.

• isNaturalPortrait

   final static Boolean isNaturalPortrait(Context context, Integer rotationDegrees)

  Determines whether the current device is a natural portrait-oriented device

  Using the current app's window to determine whether the device is a natural portrait-oriented device doesn't work in all scenarios, one example of this is multi-window mode. Taking a natural portrait-oriented device in multi-window mode, rotating it 90 degrees (so that it's in landscape), with the app open, and its window's width being smaller than its height. Using the app's width and height would determine that the device isn't naturally portrait-oriented, where in fact it is, which is why it is important to use the size of the device instead.

  Parameters:

  context - Current context.

  rotationDegrees - The device's rotation in degrees from its natural orientation.

• rotationDegreesFromSurfaceRotation

   final static Integer rotationDegreesFromSurfaceRotation(Integer rotationConstant)

  Get the int value degree of a rotation from the Surface constants.

  Valid values for the relative rotation are Surface.ROTATION_0, Surface.ROTATION_90, Surface.ROTATION_180, Surface.ROTATION_270.
