只需引入模塊，比起依賴，更方便自定義

implementation project(':imagepicker') //圖片加載 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()); //設置圖片加載器imagePicker.setShowCamera(true); //顯示拍照按鈕imagePicker.setCrop(true); //允許裁剪（單選才有效）imagePicker.setSaveRectangle(true); //是否按矩形區域保存imagePicker.setSelectLimit(8); //選中數量限制imagePicker.setStyle(CropImageView.Style.RECTANGLE); //裁剪框的形狀imagePicker.setFocusWidth(800); //裁剪框的寬度。單位像素（圓形自動取寬高最小值）imagePicker.setFocusHeight(800); //裁剪框的高度。單位像素（圓形自動取寬高最小值）imagePicker.setOutPutX(1000); //保存文件的寬度。單位像素imagePicker.setOutPutY(1000); //保存文件的高度。單位像素 }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);}}); }

回調顯示已選中圖片

@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);}} }
