package arui319.blog.csdn.net;  

import android.graphics.Bitmap;  

public class ImagePiece {  

    public int index = 0;  

    public Bitmap bitmap = null;  
}  

一個是ImageSplitter類，有一個靜態(tài)方法split，傳入的參數(shù)是要切割的Bitmap對象，和橫向和豎向的切割片數(shù)。比如傳入的是3、3，則橫豎向都切割成3片，最終會將整個圖片切割成3X3=9片。

復(fù)制代碼代碼如下:

package arui319.blog.csdn.net;  

import java.util.ArrayList;  
import java.util.List;  

import android.graphics.Bitmap;  

public class ImageSplitter {  

    public static List<ImagePiece> split(Bitmap bitmap, int xPiece, int yPiece) {  

        List<ImagePiece> pieces = new ArrayList<ImagePiece>(xPiece * yPiece);  
        int width = bitmap.getWidth();  
        int height = bitmap.getHeight();  
        int pieceWidth = width / 3;  
        int pieceHeight = height / 3;  
        for (int i = 0; i < yPiece; i++) {  
            for (int j = 0; j < xPiece; j++) {  
                ImagePiece piece = new ImagePiece();  
                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;  
    }  

}
