sinothk / ImageSelector

弃：ImageSelector: 图片多选（选后展示），单选，大图预览。

引入

Step 1. Add the JitPack repository to your build file

Add it in your root build.gradle at the end of repositories:

  allprojects {
    repositories {
      ...
      maven { url 'https://jitpack.io' }
    }
  }

Step 2. Add the dependency

dependencies {
        // implementation 'com.github.sinothk:ImageSelector:3.0.0329'
        implementation 'com.github.sinothk:ImageSelector:5.x.1105'
}

使用

预览：

  PhotoPreviewActivity.start(Activity mActivity, int position, ArrayList<String> urlOrFilePathList,int    PhotoPreviewActivity.REQUEST_PREVIEW);

图片选择：

单图：
    PhotoPickerIntent intent = new PhotoPickerIntent(ImageSelectorDemoMainActivity.this);
    intent.setSelectModel(SelectModel.SINGLE);
    intent.setSelectedPaths(path);
    intent.setShowCamera(true, "com.sinothk.image.selector.demo"); // 是否显示拍照， 默认false

    startActivityForResult(intent, REQUEST_SINGLE_CODE);
    
多图：
    PhotoPickerIntent intent = new PhotoPickerIntent(ImageSelectorDemoMainActivity.this);
    intent.setSelectModel(SelectModel.MULTI);
    intent.setSelectedPaths(path);
    intent.setMaxTotal(9);
    intent.setShowCamera(true, "com.sinothk.image.selector.demo"); // 是否显示拍照， 默认false

    startActivityForResult(intent, REQUEST_MUTILATE_CODE);
    
返回：

onActivityResult(int requestCode, int resultCode, Intent data)
    if (resultCode == RESULT_OK) {
        //图片选择返回
        if (requestCode == REQUEST_SINGLE_CODE) {
            path = data.getStringArrayListExtra(PhotoPickerActivity.EXTRA_RESULT);
            if (path != null) {
                StringBuilder s = new StringBuilder();
                for (int i = 0; i < path.size(); i++) {
                    s.append(path.get(i));
                }
                result1.setText(s.toString());
            }
        } else if (requestCode == REQUEST_MUTILATE_CODE) {
            path = data.getStringArrayListExtra(PhotoPickerActivity.EXTRA_RESULT);

            nineGridAdapter = new AppNineGridAdapter(ImageSelectorDemoMainActivity.this, path);
            nineGridView.setNineGridAdapter(nineGridAdapter);

            nineGridAdapter.setOnItemClickListener(new AppNineGridAdapter.OnItemClickListener() {
                @Override
                public void OnItemClick(int position, ArrayList<String> urlOrFilePathList) {
                     PhotoPreviewActivity.start(ImageSelectorDemoMainActivity.this, position, urlOrFilePathList); // 不要预览删除
                
                    PhotoPreviewActivity.start(ImageSelectorDemoMainActivity.this, position, urlOrFilePathList, PhotoPreviewActivity.REQUEST_PREVIEW);

                }
            });
            
            // 图片选择结果展示
            path = data.getStringArrayListExtra(PhotoPickerActivity.EXTRA_RESULT);
            mAlbumSelectedShowAdapter.setData(path);
        }
    }

选后展示：

    mRvAlbumSelected = this.findViewById(R.id.mRvAlbumSelected);

    mAlbumSelectedShowAdapter = new ImageSelectedShowAdapter(this, path, 6);
    mRvAlbumSelected.setLayoutManager(new GridLayoutManager(this, 4));
    mRvAlbumSelected.setHasFixedSize(true);
    mRvAlbumSelected.setAdapter(mAlbumSelectedShowAdapter);

    mAlbumSelectedShowAdapter.setOnItemClickListener(new ImageSelectedShowAdapter.OnItemClickListener() {
        @Override
        public void onItemClick(View view, int position) {
            if (path.size() == position) {
                //选择相册功能
                PhotoPickerIntent intent = new PhotoPickerIntent(ImageSelectorDemoMainActivity.this);
                intent.setSelectModel(SelectModel.MULTI);
                intent.setSelectedPaths(path);
                intent.setMaxTotal(6);
                intent.setShowCamera(true, "com.sinothk.image.selector.demo"); // 是否显示拍照， 默认false

                startActivityForResult(intent, REQUEST_MUTILATE_CODE);
            } else {
                //图片展示界面  - path.size()
                PhotoPreviewActivity.start(ImageSelectorDemoMainActivity.this, position, path);
            }
        }
    });

    mAlbumSelectedShowAdapter.setItemDelClick(new ImageSelectedShowAdapter.OnItemDelClickListener() {
        @Override
        public void onItemDelClick(int position) {
            dialog(position);
        }
    });
    
    /*
     * Dialog对话框提示用户删除操作
     * position为删除图片位置
     */
    protected void dialog(final int position) {
        AlertDialog.Builder builder = new AlertDialog.Builder(this);
        builder.setMessage("确认移除已添加图片吗？");
        builder.setTitle("提示");
        builder.setPositiveButton("确认", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                dialog.dismiss();

                path.remove(position);
                mAlbumSelectedShowAdapter.notifyDataSetChanged();
            }
        });
        builder.setNegativeButton("取消", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                dialog.dismiss();
            }
        });
        builder.create().show();
    }
