android 动态切割图片吗,Android 切割图片

public class ImagePiece {

public int index = 0;

public Bitmap bitmap = null;

}

/**

* 切割图片

* @param bitmap  原图片

* @param xPiece  图片横向x轴 被  xPiece等分

* @param yPiece  图片纵向y轴 被  yPiece等分

* @param size          图片宽高被等分后 计算子图片 宽 高

* @return 字图片集合  list

*/

public static Listsplit(Bitmap bitmap, int xPiece, int yPiece,int size) {

Listpieces = new ArrayList(xPiece * yPiece);

int width = bitmap.getWidth();

int height = bitmap.getHeight();

int pieceWidth = width / size;

int pieceHeight = height / size;

for (int i = 0; i < yPiece; i++) {

for (int j = 0; j < xPiece; j++) {

ImagePie piece = new ImagePie();

piece.index = j + i * xPiece;

int xValue = j * pieceWidth;

int yValue = i * pieceHeight;

piece.bitmap = Bitmap.createBitmap(bitmap, xValue, yValue,

pieceWidth, pieceHeight);

pieces.add(piece);

}

}

return pieces;
