ImagePicker

图片选择器满足你的一切需求，单选、多选、裁剪、拍照、九图、图片预览、单击放大、一应俱全，适配到Android8.0。如果UI色调不符合你的项目需求，可继承AbstractXXXActivity，重写相关布局，并在ImagePicker.getInstance().startXXX()方法中传入自定义的Activity。

扫码安装，效果更好

代码示例

在使用ImagePicker前，必须在Activity中重写onActivityResult方法

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        ImagePicker.getInstance().onActivityResult(requestCode, resultCode, data);
    }

其次实现ImageLoader，并设置到ImagePicker.getInstance().imageLoader(new GlideImageLoader())

public class GlideImageLoader implements ImageLoader {
    @Override
    public void displayFileImage(ImageView imageView, String path) {
         GlideApp.with(imageView.getContext())
                .load(Uri.fromFile(new File(path)))
                .into(imageView);
    }

    @Override
    public void displayUserImage(ImageView imageView, String path) {
         GlideApp.with(imageView.getContext()).load(path).into(imageView);
    }


    @Override
    public void displayFileVideo(String path) {

    }

    @Override
    public Class<?> displayFullImageClass() {
        return null;
    }
}

功能

拍照

        ImagePicker.getInstance()
                .crop(false)//是否裁剪
                .selectedListener(new ImagePicker.OnSelectedListener() {
                    @Override
                    public void onImageSelected(List<ImageItem> items) {
                        toast(items.toString());
                    }
                })
                .startPhotoPicker(this);

拍照并裁剪

        ImagePicker.getInstance()
                .crop(true)//是否裁剪
                .outPutY(800)//裁剪大小
                .outPutX(800)
                .selectedListener(new ImagePicker.OnSelectedListener() {
                    @Override
                    public void onImageSelected(List<ImageItem> items) {
                        toast(items.toString());
                    }
                })
                .startPhotoPicker(this);

选择单张图片并裁剪

        ImagePicker.getInstance()
                .multiMode(false)//是否多选
                .showCamera(true)//是否显示拍照Item
                .crop(false)//是否裁剪
                .outPutY(800)
                .outPutX(800)
                .selectedListener(new ImagePicker.OnSelectedListener() {
                    @Override
                    public void onImageSelected(List<ImageItem> items) {
                        toast(items.toString());
                    }
                })
                .startImagePicker(this);

选择多图

        ImagePicker.getInstance()
                .multiMode(true)//是否多选
                .selectLimit(8)//图片限制
                .showCamera(true)
                .selectedListener(new ImagePicker.OnSelectedListener() {
                    @Override
                    public void onImageSelected(List<ImageItem> items) {
                        toast(items.toString());
                    }
                })
                .startImagePicker(this, null);//第二个参数为已经选择的图片路径集合

九图显示

@BindLayout(R.layout.activity_sample_nine)
public class SampleNineActivity extends AppCompatActivity {
    RecyclerView rc_view;
    ImageAdapter imageAdapter;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_sample_nine);
        rc_view = findViewbyId(R.id.rc_view);
        imageAdapter = new ImageAdapter(this);
        imageAdapter.setRecyclerView(rc_view);
        imageAdapter.setImageSize(20, 0, 0);//九图间隔；距离左边；距离右边
        List<String> list = new ArrayList<>();
        list.add("http://dpic.tiankong.com/8n/a0/QJ6177688033.jpg");
        list.add("http://dpic.tiankong.com/6j/s5/QJ6146491299.jpg");
        list.add("http://dpic.tiankong.com/zt/pz/QJ6519443181.jpg");
        list.add("http://dpic.tiankong.com/br/ja/QJ6223394486.jpg");
        list.add("http://dpic.tiankong.com/i6/ke/QJ6322734186.jpg");
        list.add("http://dpic.tiankong.com/cl/at/QJ6769314375.jpg");
        list.add("http://dpic.tiankong.com/xp/3t/QJ6230352510.jpg");
        list.add("http://dpic.tiankong.com/37/ha/QJ6534800776.jpg");
        list.add("http://dpic.tiankong.com/5p/33/QJ6215180920.jpg");
        imageAdapter.bindData(list);
    }


    @Override
    public void onActivityReenter(int resultCode, Intent data) {
        super.onActivityReenter(resultCode, data);
        imageAdapter.onActivityReenter(resultCode, data);
    }
}

图片预览(放大缩小)

        List<String> list = new ArrayList<>();
        list.add("http://dpic.tiankong.com/8n/a0/QJ6177688033.jpg");
        list.add("http://dpic.tiankong.com/6j/s5/QJ6146491299.jpg");
        list.add("http://dpic.tiankong.com/zt/pz/QJ6519443181.jpg");
        list.add("http://dpic.tiankong.com/br/ja/QJ6223394486.jpg");
        list.add("http://dpic.tiankong.com/i6/ke/QJ6322734186.jpg");
        list.add("http://dpic.tiankong.com/cl/at/QJ6769314375.jpg");
        list.add("http://dpic.tiankong.com/xp/3t/QJ6230352510.jpg");
        list.add("http://dpic.tiankong.com/37/ha/QJ6534800776.jpg");
        list.add("http://dpic.tiankong.com/5p/33/QJ6215180920.jpg");
        ImagePicker.getInstance().startImageViewer(this, list);

视频选择

        ImagePicker.getInstance()
                .selectedListener(new ImagePicker.OnSelectedListener() {
                    @Override
                    public void onImageSelected(List<ImageItem> items) {
                        toast(items.toString());
                    }
                })
                .startVideoPicker(this);
