use of com.lzy.imagepicker.adapter.ImagePageAdapter in project ImagePicker by jeasonlzy.

the class ImagePreviewBaseActivity method onCreate.

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    // 据说这样会导致大量图片崩溃
    mImageItems = (ArrayList<ImageItem>) getIntent().getSerializableExtra(ImagePicker.EXTRA_IMAGE_ITEMS);
    // 下面采用弱引用会导致预览崩溃
    //        mImageItems =  (ArrayList<ImageItem>) DataHolder.getInstance().retrieve(DataHolder.DH_CURRENT_IMAGE_FOLDER_ITEMS);
    imagePicker = ImagePicker.getInstance();
    selectedImages = imagePicker.getSelectedImages();
