Constructors Summary
public LinearGradient(float x0, float y0, float x1, float y1, int[] colors, float[] positions, TileMode tile) Create a shader that draws a linear gradient along a line. param x0 The x-coordinate for the start of the gradient line param y0 The y-coordinate for the start of the gradient line param x1 The x-coordinate for the end of the gradient line param y1 The y-coordinate for the end of the gradient line param colors The colors to be distributed along the gradient line param positions May be null. The relative positions [0..1] of each corresponding color in the colors array. If this is null, the the colors are distributed evenly along the gradient line. param tile The Shader tiling mode if (colors.length < 2) { throw new IllegalArgumentException("needs >= 2 number of colors"); } if (positions != null && colors.length != positions.length) { throw new IllegalArgumentException("color and position arrays must be of equal length"); } mType = TYPE_COLORS_AND_POSITIONS; mX0 = x0; mY0 = y0; mX1 = x1; mY1 = y1; mColors = colors; mPositions = positions; mTileMode = tile; init(nativeCreate1(x0, y0, x1, y1, colors, positions, tile.nativeInt));
