KwikPicker for Android

A simple Kotlin based image picker using BottomSheet In Google's Material Design, Google introduced Bottom sheets.(Components – Bottom sheets)
Bottom sheets slide up from the bottom of the screen to reveal more content.

If you want pick an image from gallery or take a picture, this library can help easily.
KwikPicker provide 3 options:

1. Take a picture by camera(using MediaStore.ACTION_IMAGE_CAPTURE intent)
2. Get image from gallery(using Intent.ACTION_PICK intent)
3. Get image from recent image(using MediaStore.Images.Media.EXTERNAL_CONTENT_URI cursor)

KwikPicker is simple image picker using bottom sheet.

How to use

1. Check Permission

You have to grant WRITE_EXTERNAL_STORAGE permission from user.
If your targetSDK version is 23+, you have to check permission and request permission to user.
Because after Marshmallow (6.0), you have to not only declare permissions in AndroidManifest.xml, but also request permissions at runtime.
There are so many permission check library in Android-Arsenal
I recommend TedPermission
TedPermission is super simple and smart permission check library.

2. Start TedBottomPicker

TedBottomPicker class extend BottomSheetDialogFragment.
TedBottomPicker.Builder make new TedBottomPicker().
After then, you can show TedBottomPicker

    val kwikPicker = KwikPicker.Builder(this@MainActivity,
        imageProvider = { imageView, uri ->
            Glide.with(activity)//Any image provider here!
                .load(uri)
                .into(imageView)
        },
        onImageSelectedListener = { uri: Uri ->
            image.visibility = View.VISIBLE
            mSelectedImagesContainer.visibility = View.GONE
            image.post {
                mGlideRequestManager
                    .load(uri)
                    .into(image)
            }
        },
        peekHeight = 1200)
        .create(activity)
    kwikPicker.show(supportFragmentManager)

If you want select multi image, you can use OnMultiImageSelectedListener

    val kwikPicker = KwikPicker.Builder(activity,
        imageProvider = { imageView, uri ->
            Glide.with(this@MainActivity)
                .load(uri)
                .into(imageView)
        },
        onMultiImageSelectedListener = { list: ArrayList<Uri> ->
            showUriList(list)
        },
        peekHeight = 1600,
        showTitle = false,
        completeButtonText = "Done",
        emptySelectionText = "No Selection")
    .create(activity)
    kwikPicker.show(supportFragmentManager)

Don't forget!!
You have to pass both an image provider, and either an 'imageSelectedListener' or multiImageSelectedListener in the Builder.
This listener will pass selected Uri/UriList.
