一、请求系统相机权限

 1 private static final int TAKE_PHOTO_REQUEST_CODE = 1;
 2 
 3     public static String takePhoto(Context context, int requestCode) 
 4         String filePath = "";
 5         if (ContextCompat.checkSelfPermission(context,
 6                 Manifest.permission.CAMERA)
 7                 != PackageManager.PERMISSION_GRANTED) 
 8             ActivityCompat.requestPermissions((Activity) context,
 9                     new String[]Manifest.permission.CAMERA,
10                     TAKE_PHOTO_REQUEST_CODE);
11          else 
12             Intent intent = new Intent(
13                     MediaStore.ACTION_IMAGE_CAPTURE, null);
14             filePath = AppApplication.getInstance().getCachePath() + File.separator + MD5.md5(String.valueOf(System.currentTimeMillis())) + "camera" + ".png";
15             intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri
16                     .fromFile(new File(filePath)));
17             ((Activity) context).startActivityForResult(intent, requestCode);
18 
19         
20         return filePath;
21     

二、获取相册照片要申请的权限

				if (ContextCompat.checkSelfPermission(mContext,
						Manifest.permission.READ_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) 
					ActivityCompat.requestPermissions((Activity) mContext,
							new String[]  Manifest.permission.READ_EXTERNAL_STORAGE ,
							SELECT_PHOTO_REQUEST_CODE);
				 else 
					// 从相册中选择图片
					Intent intent2 = new Intent(
							Intent.ACTION_PICK,
							android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
					// CHOSE_PIC设置标识
					((Activity) mContext).startActivityForResult(intent2,
							CHOSE_PIC);
