Android Studio-从（常规）图库中选择多张图片

Question

I want a user to be able to select multiple images from the 'normal' gallery. It currently opens a sort of file explorer instead of the gallery. Is there anything I can do so it uses the 'normal' gallery?

I currently open the file explorer/gallery the following way:

    Intent gallery = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.INTERNAL_CONTENT_URI);
    gallery.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);
    gallery.setAction(Intent.ACTION_GET_CONTENT);
    startActivityForResult(Intent.createChooser(gallery, "Select Picture"), 5);

Answer 1

Try to filter the results for image type. Something like this:

Intent photoPickerIntent = new Intent(Intent.ACTION_PICK);
photoPickerIntent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);
photoPickerIntent.setType("image/*");
startActivityForResult(photoPickerIntent, RESULT_LOAD_IMG);

Adding this would probably be enough for your code:

gallery.setType("image/*");

There are over 20,000 Android device models. There will be dozens, if not hundreds, of pre-installed gallery apps, in addition to those that users install. There is no "normal".

There is also no requirement for any of those gallery apps to support multiple selection.

It currently opens a sort of file explorer instead of the gallery.

My guess is that you are referring to the UI brought up by ACTION_GET_CONTENT .

Is there anything I can do so it uses the 'normal' gallery?

Remove the ACTION_GET_CONTENT line, so that your Intent action is ACTION_PICK .

Bear in mind that since ACTION_PICK is not documented to support EXTRA_ALLOW_MULTIPLE — and since support for extras is always optional — very few devices are likely to return multiple images to you.

Also bear in mind that ACTION_PICK is not guaranteed to display something that you might consider to be a gallery app.
