注：我是在上一篇部落格：“手機拍照及簡單的圖片壓縮”的基礎上改的，所以，許可權等，參考上一篇，這裡只對核心程式碼做說明
圖片被裁剪後，清晰度不夠，這個問題我沒解決
1、效果圖：

2、程式碼：
2.1：全域性變數：

/**
 * 用於儲存全域性變數值
 */
public class CHEN {

    /**
     * 裁剪後圖片儲存的地址
     */
    public static String crop_img_path = Environment.getExternalStorageDirectory() + "/chen/crop";

    /**
     * 拍照的返回請求碼
     */
 

    public static int TakePhotoRequestCode = 123;

    /**
     * 裁剪的返回請求碼
     */
    public static int CropImgRequestCode = 234;

}
