推荐一个安卓图片/视频/文件选择器。简单好用。
不多废话。直接上代码：

首先，添加依赖：

	//图片选择器api 'io.github.lucksiege:pictureselector:v3.11.1'//图片压缩api 'io.github.lucksiege:compress:v3.11.1'//图片裁剪api 'io.github.lucksiege:ucrop:v3.11.1'//自定义相机api 'io.github.lucksiege:camerax:v3.11.1'api 'com.github.bumptech.glide:glide:4.12.0'

这些依赖是必须的。其次是封装一下，方便后续使用
首先，创建 VideoThumbListener.java：

public class VideoThumbListener implements OnVideoThumbnailEventListener {private Context context;public VideoThumbListener(Context context) {this.context = context;}@Overridepublic void onVideoThumbnail(Context context, String videoPath, OnKeyValueResultCallbackListener call) {Glide.with(context).asBitmap().sizeMultiplier(0.6F).load(videoPath).into(new CustomTarget<Bitmap>() {@Overridepublic void onResourceReady(@NonNull Bitmap resource, @Nullable Transition<? super Bitmap> transition) {ByteArrayOutputStream stream = new ByteArrayOutputStream();resource.compress(Bitmap.CompressFormat.JPEG, 60, stream);FileOutputStream fos = null;String result = null;try {File targetFile = new File(getVideoThumbnailDir(), "thumbnails_" + System.currentTimeMillis() + ".jpg");fos = new FileOutputStream(targetFile);fos.write(stream.toByteArray());fos.flush();result = targetFile.getAbsolutePath();} catch (IOException e) {e.printStackTrace();} finally {PictureFileUtils.close(fos);PictureFileUtils.close(stream);}if (call != null) {call.onCallback(videoPath, result);}}@Overridepublic void onLoadCleared(@Nullable Drawable placeholder) {if (call != null) {call.onCallback(videoPath, "");}}});}private String getVideoThumbnailDir() {File externalFilesDir = context.getExternalFilesDir("");File customFile = new File(externalFilesDir.getAbsolutePath(), "Thumbnail");if (!customFile.exists()) {customFile.mkdirs();}return customFile.getAbsolutePath() + File.separator;}
}

再次就是图片加载器的封装：GlideUtils：

public class GlideUtils implements ImageEngine {/*** 加载图片** @param context   上下文* @param url       资源url* @param imageView 图片承载控件*/@Overridepublic void loadImage(Context context, String url, ImageView imageView) {if (!ActivityCompatHelper.assertValidRequest(context)) {return;}Glide.with(context).load(url)// .error(R.mipmap.icon_photo_error).into(imageView);}/*** 加载图片** @param context    上下文* @param url        资源url* @param imageView  图片承载控件* @param errorImage 图片加载失败资源文件*/public void loadImage(Context context, String url, ImageView imageView, int errorImage) {if (!ActivityCompatHelper.assertValidRequest(context)) {return;}Glide.with(context).load(url).error(errorImage).into(imageView);}@Overridepublic void loadImage(Context context, ImageView imageView, String url, int maxWidth, int maxHeight) {if (!ActivityCompatHelper.assertValidRequest(context)) {return;}Glide.with(context).load(url)
//                .error(R.mipmap.ic_launcher).override(maxWidth, maxHeight).into(imageView);}/*** 加载相册目录封面** @param context   上下文* @param url       图片路径* @param imageView 承载图片ImageView*/@Overridepublic void loadAlbumCover(Context context, String url, ImageView imageView) {if (!ActivityCompatHelper.assertValidRequest(context)) {return;}Glide.with(context).asBitmap().load(url)
//                .error(R.mipmap.ic_launcher).override(180, 180).sizeMultiplier(0.5f).transform(new CenterCrop(), new RoundedCorners(8))
//                .placeholder(R.mipmap.ic_launcher).into(imageView);}/*** 默认图片** @param context* @param url* @param imageView*/public void loadVideoThumb(Context context, String url, ImageView imageView) {loadVideoThumb(context, url, 0, imageView);}public void loadVideoThumb(Context context, String url, int errorImage, ImageView imageView) {Glide.with(context).setDefaultRequestOptions(new RequestOptions().frame(1000000).centerCrop().error(errorImage).placeholder(errorImage)).load(url).into(imageView);}/*** 获取视频第一证* @param path 文件路径* @return*/public Bitmap loadVideoThumb(String path) {MediaMetadataRetriever media = new MediaMetadataRetriever();media.setDataSource(path);return media.getFrameAtTime();}/*** 加载图片列表图片** @param context   上下文* @param url       图片路径* @param imageView 承载图片ImageView*/@Overridepublic void loadGridImage(Context context, String url, ImageView imageView) {if (!ActivityCompatHelper.assertValidRequest(context)) {return;}Glide.with(context).load(url).override(200, 200).centerCrop()
//                .error(R.mipmap.ic_launcher)
//                .placeholder(R.mipmap.ic_launcher).into(imageView);}@Overridepublic void pauseRequests(Context context) {Glide.with(context).pauseRequests();}@Overridepublic void resumeRequests(Context context) {Glide.with(context).resumeRequests();}private GlideUtils() {}private static final class InstanceHolder {static final GlideUtils instance = new GlideUtils();}public static GlideUtils createGlideEngine() {return InstanceHolder.instance;}
}

最后。就是正题了，PictureUtils.java：

}

至于封装，到此就结束了。最后看一下用法，举例：：

打开相机：

PictureUtils.openCamera(this,false){val localMedia = it[0]
}

选择X张照片：

PictureUtils.createImageMax(this, 9, arrayListOf<LocalMedia>()){it.forEach { section ->// section.realPath：获取图片路径}
}

就简单列举两个。剩下的都差不多。
使用的时候别忘记添加权限哟。
