我正在编写一个教堂应用程序，其中我使用存储在 SD 卡中的图像填充列表，但现在我想计算列表项的总数。

for(int position = 0; position < lstView.getAdapter().getCount(); position++)

flags.put(position, true);
}
((BaseAdapter) lstView.getAdapter()).notifyDataSetChanged();
}
});
/*** Get Images from SDCard ***/
listSDCardImages = fetchSDCardImages();
// ListView and imageAdapter
lstView = (ListView) findViewById(R.id.listSDCardImages);
lstView.setAdapter(new ListSDCardImagesAdapter(this));
