结果:

1.如果要取本地相册的话,小米手机要注意一下,不能取网络相册。

 

操作:

1.两个 TButton (Button1 和 Button2) , 一个 TActionList(ActionList1) ,一个 TImage(Image1)。

2.Button1 的 stylelookup 选 择 cameratoolbutton , Button1 的 stylelookup 选择organizetoolbutton。

3.双击 ActionList1,在弹出的对话框中点击右键菜单中的new standard action,然后选择TakePhotoFromLibraryAction( 从图片库中选择照片)和TakePhotoFromCameraAction(通过相机拍摄照片),这样就加入了两个标准的 Action。

4.在 TakePhotoFromCameraAction1 的 onDidFinishTaking 事件中写如下代码:

Image1.Bitmap.Assign(Image);

同样,在 TakePhotoFromLibraryAction1 的 onDidFinishTaking 事件中写如下代码:

Image1.Bitmap.Assign(Image);
