android - android从应用程序中选择多张照片，但不是图库图像

Question

从之前的许多帖子中，我现在可以让我的应用程序启动 Intent，这将允许用户选择多个图像。
但是当我只想要照片时，意图会同时显示图库图像和照片。
图库图像没有用，只会让用户感到困惑。

所以我的问题是如何将呈现给用户的图像限制为只有照片而不是画廊。

我目前使用的代码如下：

 @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.galleryimagepicker);
    lnrImages = (LinearLayout)findViewById(R.id.lnrImages);

    btnAddPhotos = (Button)findViewById(R.id.btnAddPhotos);
    btnAddPhotos.setOnClickListener(this);

    btnSaveImages = (Button)findViewById(R.id.btnSaveImages);
    btnSaveImages.setOnClickListener(this);
}

@Override
public void onClick(View view) {
    switch (view.getId()) {
        case R.id.btnAddPhotos:
            /*Intent intent = new Intent(GalleryImagePicker.this,CustomPhotoGalleryActivity.class);
            startActivityForResult(intent,PICK_IMAGE_MULTIPLE);*/
            Intent intent = new Intent(GalleryImagePicker.this,CustomPhotoGalleryActivity.class);
            intent.setType("image/*");
            intent.setAction(Intent.ACTION_GET_CONTENT);
            startActivityForResult(intent,PICK_IMAGE_MULTIPLE);
            break;

        case R.id.btnSaveImages:
            if(imagesPathList != null)
            {
                if(imagesPathList.size() >= 1) {
                    //Toast.makeText(GalleryImagePicker.this, imagesPathList.size() + " no of images are selected", Toast.LENGTH_SHORT).show();
                    String[] stringArray = imagesPathList.toArray(new String[0]);
                    for (int i = 0; i < stringArray.length; i++){
                        String ThisImgPath = stringArray[i];
                        String PicName = ThisImgPath;
                        if (SystemIOFile.exists(PicName)) {
                            BitmapFactory.Options bmOptions = new BitmapFactory.Options();
                            bmOptions.inSampleSize = 4;
                            Bitmap bm = BitmapFactory.decodeFile(ThisImgPath, bmOptions);
                            Uri ThisUri = getImageUri(cntxt, bm);
                            bm = decodeBitmap(cntxt, ThisUri, bmOptions.inSampleSize);

                            Boolean HOLD = true;
                        }

                        Boolean HOLD = true;
                    }
                }else{
                    Toast.makeText(GalleryImagePicker.this, imagesPathList.size() + " no of image are selected", Toast.LENGTH_SHORT).show();
                }
            }
            else
            {
                Toast.makeText(GalleryImagePicker.this," no images are selected", Toast.LENGTH_SHORT).show();
            }
            break;
    }
}  

编辑： CustomPhotoGalleryActivity 代码：

    int image_column_index = imagecursor.getColumnIndex(MediaStore.Images.Media._ID);
    this.count = imagecursor.getCount();
    this.arrPath = new String[this.count];
    ids = new int[count];
    this.thumbnailsselection = new boolean[this.count];
    for (int i = 0; i < this.count; i++) {
        imagecursor.moveToPosition(i);
        ids[i] = imagecursor.getInt(image_column_index);

    }

            int cnt = 0;
            String selectImages = "";
            for (int i = 0; i < len; i++) {
                if (thumbnailsselection[i]) {
                    cnt++;
