public class PhoneUtils {
/**
* 使用方式:
*
* 1.獲取拍照原圖Bitmap: PhoneUtils.onInitPhoneResult(this,requestCode,resultCode,data,"init.jpg")
* 參數列表：上下文環境，請求碼，響應碼，返回的數據，圖片名稱
* 注：請求碼，響應碼，返回的數據是onActivityResult（）方法的參數
* 2.獲取必定壓縮比例的原圖
* （1）方式一：拍照保存：PhoneUtils.onInitPhoneResult(this,requestCode,resultCode,data,"init.jpg")
* 將拍照保存路徑下的照片進行處理 PhoneUtils.getBitmapOption(Environment.getExternalStorageDirectory() + "/phone/init.jpg", 20))
* 參數：拍照保存的全路徑，縮放比列（20表示縮放比爲原圖的1/20）
* （2）方式二：將現有的bitmap進行壓縮處理：
* 將bitmap保存：PhoneUtils.saveBitmapFile(bitmap,filePath);
* 參數：有效的bitmap，保存的全路徑
* 將保存路徑下的bitmap進行壓縮：PhoneUtils.getBitmapOption(filePath, 20))
* 參數：保存的全路徑，縮放比列
* 3.保存一個bitmap:PhoneUtils.saveBitmapFile(bitmap,filePath);
* 參數：有效的bitmap，保存的全路徑
* 4.縮放一個一個路徑下的bitmap：PhoneUtils.getBitmapOption(filePath, 20))
* 參數：保存的全路徑，縮放比列
* 5.獲取一個拍照縮略圖：
* 拍照：PhoneUtils.getAbbreviationsPhone(this);
* 在onActivityResult（）中PhoneUtils.onAbbreviationsPhoneResult(this,requestCode,resultCode,data)
* 參數：上下文，請求碼，響應碼，返回數據
* 6.獲取相冊選擇的單個圖片：
* （1）：獲得一個圖片的bitmap：
* 調用相冊：PhoneUtils.getAlbumPhone(上下文環境);
* 在onActivityResult（）中PhoneUtils.onmyPhoneResult(this,requestCode,resultCode,data);獲得bitmap
* （2）：獲得一個圖片的file:
* 調用相冊：PhoneUtils.getAlbumPhone(上下文環境);
* 在onActivityResult（）中PhoneUtils.onmyPhoneFileResult(this,requestCode,resultCode,data);獲得file
* 7.獲取拍照剪切圖片：
* 調用PhoneUtils.getSheraPack(this,"cut.jpg");
* 在在onActivityResult（）中監聽PHONE_CODE_SHEAR_PACK響應碼調用Uri packUri =PhoneUtils.onInitCutPhoneResult(this,requestCode,resultCode,data,"cut.jpg");得到拍照的原圖
* 在調用PhoneUtils.crop(this,packUri)進去截圖
* 在在onActivityResult（）中監聽PHONE_CODE__CUT截圖完畢響應碼 Bitmap photo=data.getParcelableExtra("data");
* 得到phone這個截圖後的bitmap
* 8.獲取相冊剪切圖片：
* 調用PhoneUtils.getSheraMyPhone(this);進入相冊請求圖片
* 在在onActivityResult（）中監聽PHONE_CODE__SHEAR_MYPHONE響應碼調用Uri myUri=PhoneUtils.onCutmyPhoneResult(this,requestCode,resultCode,data);;得到相冊圖片uri
* 在調用PhoneUtils.crop(this,myUri)進去截圖
* 在在onActivityResult（）中監聽PHONE_CODE__CUT截圖完畢響應碼 Bitmap photo=data.getParcelableExtra("data");
* 得到phone這個截圖後的bitmap
* 9.選擇相冊多張圖片：

能夠把相關數據存儲到裏面，須要的時候獲取處理啊，如何存儲，如何獲取以下：數組
存儲：安全
SharedPreferencesUtils.put(OcrPhotoActivity.this,"ID_img_font","12345");
獲取：app
String ID_img_font_path = (String) SharedPreferencesUtils.get(OcrPhotoActivity.this,"ID_img_font","");
