Method Detail

getScaledEdge

public SquareImageView.Edge getScaledEdge()

Returns the edge of the image view, which is scaled in order to ensure, that width and height are equal. E.g., if the scaled edge is SquareImageView.Edge.VERTICAL, the height of the image view is adapted to fit its width.

Returns:

The edge of the image view, which is scaled in order to ensure, that width and height are equal, as a value of the enum SquareImageView.Edge. The edge may either be SquareImageView.Edge.HORIZONTAL or SquareImageView.Edge.VERTICAL

setScaledEdge

public final void setScaledEdge(SquareImageView.Edge edge)

Sets the edge of the image view, which should be scaled in order to ensure, that width and height are equal. E.g., if the scaled edge is SquareImageView.Edge.VERTICAL, the height of the image view is adapted to fit its width.

Parameters:

edge - The edge, which should be set, as a value of the enum SquareImageView.Edge. The edge may either be SquareImageView.Edge.HORIZONTAL or SquareImageView.Edge.VERTICAL

onMeasure

protected final void onMeasure(int widthMeasureSpec,
                               int heightMeasureSpec)
