Android Gallery的最大图像选择限制 [英] maximum image selection limit from gallery Android

问题描述

我试图从我的应用程序内部的Gallery内置应用程序中获取图像的Uri.

I am trying to get image's Uri in the Gallery built-in app from inside my application.

所以，我在下面使用Intent，但是它选择了更多图像.

so, I was using the Intent below, but it selected many more image.

我想设置限制.少于3

i want to set limitation. less than 3

@Override
public void onClick(View v) {
    Intent intent = new Intent( );
    intent.setType("image/*");
    intent.setAction(Intent.ACTION_GET_CONTENT);
    intent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);
    startActivityForResult(Intent.createChooser(intent, "select images"), PICK_IMAGE_MULTIPLE);
}

我该如何解决.

您有什么建议吗?

推荐答案

不幸的是，如 http://developer.android.com/reference/android/content/Intent.html#EXTRA_ALLOW_MULTIPLE ，这是不可能的.

Unfortunately, as stated by http://developer.android.com/reference/android/content/Intent.html#EXTRA_ALLOW_MULTIPLE, this is not possible.

这是布尔值；默认为false.如果为true，则允许实现为用户提供一个UI，在其中用户可以选择全部返回给调用者的多个项目.

This is a boolean extra; the default is false. If true, an implementation is allowed to present the user with a UI where they can pick multiple items that are all returned to the caller.

您必须手动检查返回的数据以查看其是否超过3个项目，如果是，请显示

You'll have to manually check the returned data to see if it's more than 3 items, and if so, show a Toast and let them try again.
