在uni-app中提供的封装好的api中没有提供获取手机相册的能力，只能打开相册后由用户选择其中的照片，而插件库中提供的获取相册的插件都是收费的，这里为大家分享一个可以自己获取android相册的代码段：

	        getImageList() {
                let imageList = []
				let MediaStore = plus.android.importClass('android.provider.MediaStore');
				let photoColumns= [
						MediaStore.Images.Media._ID,
						MediaStore.Images.Media.DATA,
						MediaStore.Images.Media.DATE_ADDED
					]
				let main = plus.android.runtimeMainActivity();
				let resolver = main.getContentResolver();
				plus.android.importClass(resolver);
				let cursor=resolver.query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, photoColumns, null, null, null)
				plus.android.importClass(cursor);
				while (cursor.moveToNext()) {
					let _id = cursor.getString(cursor.getColumnIndexOrThrow(MediaStore.Images.Media._ID))
					let filePath = cursor.getString(cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA))
					let dateAdded = cursor.getLong(cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATE_ADDED))
					imageList.push({
						filePath: filePath,
						dateAdded: dateAdded
					})
				}
				cursor.close()
				return imageList
			}
