实现效果

 

 

只需引入模块，比起依赖，更方便自定义

implementation project(':imagepicker')
//图片加载
implementation 'com.github.bumptech.glide:glide:4.11.0'

初始化即可使用

private void initImagePicker() {ImagePicker imagePicker = ImagePicker.getInstance();imagePicker.setImageLoader(new GlideImageLoader());   //设置图片加载器imagePicker.setShowCamera(true);                      //显示拍照按钮imagePicker.setCrop(true);                           //允许裁剪（单选才有效）imagePicker.setSaveRectangle(true);                   //是否按矩形区域保存imagePicker.setSelectLimit(8);              //选中数量限制imagePicker.setStyle(CropImageView.Style.RECTANGLE);  //裁剪框的形状imagePicker.setFocusWidth(800);                       //裁剪框的宽度。单位像素（圆形自动取宽高最小值）imagePicker.setFocusHeight(800);                      //裁剪框的高度。单位像素（圆形自动取宽高最小值）imagePicker.setOutPutX(1000);                         //保存文件的宽度。单位像素imagePicker.setOutPutY(1000);                         //保存文件的高度。单位像素
}private void initre() {mRecyclerView.setLayoutManager(new GridLayoutManager(this, 4));evaluateAdapter = new EvaluateAdapter(this);mRecyclerView.setAdapter(evaluateAdapter);evaluateAdapter.setClickListener(new EvaluateAdapter.ClickListener() {@Overridepublic void add(int position) {Intent picture = new Intent(WxSelectPicActivity.this, ImageGridActivity.class);picture.putExtra(ImageGridActivity.EXTRAS_IMAGES, selectImage);startActivityForResult(picture, IMAGE_PICKER);}@Overridepublic void preview(int position) {Intent intentPreview = new Intent(WxSelectPicActivity.this, ImagePreviewDelActivity.class);intentPreview.putExtra(ImagePicker.EXTRA_IMAGE_ITEMS, (ArrayList<ImageItem>) evaluateAdapter.getData());intentPreview.putExtra(ImagePicker.EXTRA_SELECTED_IMAGE_POSITION, position);intentPreview.putExtra(ImagePicker.EXTRA_FROM_ITEMS, true);startActivityForResult(intentPreview, REQUEST_CODE_PREVIEW);}});
}

 

回调显示已选中图片

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {super.onActivityResult(requestCode, resultCode, data);if (resultCode == ImagePicker.RESULT_CODE_ITEMS) {if (data != null && requestCode == IMAGE_PICKER) {ArrayList<ImageItem> images = (ArrayList<ImageItem>) data.getSerializableExtra(ImagePicker.EXTRA_RESULT_ITEMS);selectImage.clear();selectImage.addAll(images);evaluateAdapter.setNewData(images);}} else if (resultCode == ImagePicker.RESULT_CODE_BACK) {if (data != null && requestCode == REQUEST_CODE_PREVIEW) {ArrayList<ImageItem> images = (ArrayList<ImageItem>) data.getSerializableExtra(ImagePicker.EXTRA_IMAGE_ITEMS);selectImage.clear();selectImage.addAll(images);evaluateAdapter.setNewData(images);}}
}
