Android适配器-使用哪个？

Question

I am still unclear about which adapter to use in a situation that doesn't require the basic, SimpleAdapter. There are BaseAdapters, ArrayAdapters, CustomAdapters, etc.

I would like to make a ListView with a simple layout like seen in the comment section in the Google PlayStore. A TextView on one side, and an image that pops up a context menu of some sort.

What adapter would I use for this that would work best?

In your case it is easier to use a SimpleAdapter . Just provide your custom layout and connect the data with the widgets' id. Something similar to this:

List<HashMap<String,String>> datalist = new ArrayList<HashMap<String,String>>();

HashMap<String, String> map = new HashMap<String,String>();
map.put("text", "some text");
map.put("image",Integer.toString( R.drawable.your_image_to_popup_a_menu ));
datalist.add( map );

String[] from = { "text","image" };
int[] to = { R.id.txt,R.id.img };

SimpleAdapter adapter = new SimpleAdapter( this, datalist, R.layout.your_layout, from, to);

Do not forget to identify the layout's TextView and ImageView as "@+id/txt" and "@+id/img" respectively.

(If your image is always the same, just set it in the layout and forget linking the R.id.img part)
