How Do I Use ?

Gradle:

repositories {
    jcenter()
}

dependencies {
    compile 'com.prim.lib:prim-picker:1.0.4'
}

Permission:

android.permission.READ_EXTERNAL_STORAGE
android.permission.WRITE_EXTERNAL_STORAGE
android.permission.CAMERA

如果运行Android 6.0+ 需要动态申请权限

首先需要设置图片加载器,此处自己实现 ImageEngine 接口,好处:本库不用再导入图片加载库了,防止项目中图片加载库冲突或多个图片加载库

需要注意的是:
加载缩略图设置图片类型为centerCrop();
加载预览图设置图片类型为fitCenter();

class ImageLoader : ImageEngine {
        override fun loadImageThumbnail(context: Context?, resize: Int, placeholder: Drawable?, view: ImageView?, uri: Uri?) {
            Glide.with(context).load(uri).asBitmap().placeholder(placeholder).override(resize, resize).centerCrop().into(view)
        }

        override fun loadImage(context: Context?, resizeX: Int, resizeY: Int, placeholder: Drawable?, view: ImageView?, uri: Uri?) {
            Glide.with(context).load(uri).asBitmap().placeholder(placeholder).override(resizeX, resizeY).fitCenter().into(view)
        }

        override fun loadGifThumbnail(context: Context?, resize: Int, placeholder: Drawable?, view: ImageView?, uri: Uri?) {
            Glide.with(context).load(uri).asGif().placeholder(placeholder).override(resize, resize).centerCrop().into(view)
        }

        override fun loadGifImage(context: Context?, resizeX: Int, resizeY: Int, placeholder: Drawable?, view: ImageView?, uri: Uri?) {
            Glide.with(context).load(uri).asGif().placeholder(placeholder).override(resizeX, resizeY).into(view)
        }

    }

     */
    public PreviewBuilder setImageLoader(ImageEngine imageLoader) {
        this.selectSpec.imageLoader = imageLoader;
        return this;
    }

select file(选择文件)

          PrimPicker
                .with(this)
                .choose(MimeType.ofImage())
                .setSpanCount(3)
                .setMaxSelected(9)
                .setImageLoader(ImageLoader())
                .setShowSingleMediaType(true)
                .setCapture(true)
                .setDefaultItems(list)
                .lastGo(1001)

get select file date(获取选择文件的数据)

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
        super.onActivityResult(requestCode, resultCode, data)
        if (requestCode == 1001 && resultCode == Activity.RESULT_OK) {
            list = PrimPicker.obtainItemsResult(data)
            pathlist = PrimPicker.obtainPathResult(data)
        }
    }

Get Uri or Path or MediaItem

 /** 获取返回值 uri */
    public static ArrayList<Uri> obtainUriResult(Intent data) {
        return data.getParcelableArrayListExtra(EXTRA_RESULT_SELECTION);
    }

    /** 获取返回值 string path */
    public static ArrayList<String> obtainPathResult(Intent data) {
        return data.getStringArrayListExtra(EXTRA_RESULT_SELECTION_PATH);
    }

    /** 获取返回值 boolean 是否压缩 如压缩需自己处理,本库没有实现该功能 */
    public static boolean obtainCompressResult(Intent data) {
        return data.getBooleanExtra(EXTRA_RESULT_COMPRESS, false);
    }

    /** 获取返回值 MediaItem 追加文件或预览文件时使用 */
    public static ArrayList<MediaItem> obtainItemsResult(Intent data) {
        return data.getParcelableArrayListExtra(EXTRA_RESULT_ITEMS);
    }

Add File(追加文件)

setDefaultItems(list) 选择文件得到的返回数据List list 你可以对文件删除部分,想追加新的文件,将对list操作后的数据传入

         PrimPicker
                .with(this)
                .choose(MimeType.ofImage())
                .setSpanCount(3)
                .setMaxSelected(9)
                .setImageLoader(ImageLoader())
                .setShowSingleMediaType(true)
                .setCapture(true)
                .setDefaultItems(list)
                .lastGo(1001)

PerView File(对选择返回后的文件预览)

            PrimPicker
                    .with(this)
                    .preview(MimeType.ofImage())
                    .setImageLoader(ImageLoader())
                    .setPreviewItems(list)
                    .lastGo(1001)
