android 调用相册-照相机封装

把这两个功能封装起来，经常使用到。

private static Uri photoUri;
	public static final int NONE = 0;
	public static final int PHOTOHRAPH = 1;// 拍照
	public static final int PHOTOZOOM = 2; // 缩放
	public static final int PHOTORESULT = 3;// 结果
	public static final String IMAGE_UNSPECIFIED = "image/*";
	/**
	 * 进入照相机
	 * @param activity
	 */
	public static void startCamera(Activity activity) {
		  Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);//"android.media.action.IMAGE_CAPTURE"
          ContentValues values = new ContentValues();
          photoUri = activity.getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
          intent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, photoUri);
          /**-----------------*/
          activity.startActivityForResult(intent, PHOTOHRAPH);
	}

	/**
	 * 进入相册
	 * @param activity
	 */
	public static  void startPhotoAlbum(Activity activity) {
		Intent intent = new Intent(Intent.ACTION_PICK, null);
        intent.setDataAndType(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, IMAGE_UNSPECIFIED);
        activity.startActivityForResult(intent, PHOTOZOOM);
	}

	/**
	 * 裁剪照片 跳系统的activity
	 * @param activity
	 * @param uri
	 */
	public static void startPhotoZoom(Activity activity, Uri uri) {
		Intent intent = new Intent("com.android.camera.action.CROP");
		intent.setDataAndType(uri, IMAGE_UNSPECIFIED);
		intent.putExtra("crop", "true");
		// aspectX aspectY 是宽高的比例
		intent.putExtra("aspectX", 1);
		intent.putExtra("aspectY", 1);
		// outputX outputY 是裁剪图片宽高
		intent.putExtra("outputX", 300); // 决定图片的像素
		intent.putExtra("outputY", 300); // 决定图片的像素
		intent.putExtra("return-data", true);
		activity.startActivityForResult(intent, PHOTORESULT);
	}
