android在listview中放入从sdcard读取的bitmap

重写viewbinder

public class viewbinder_bookmark implements SimpleAdapter.ViewBinder{@Overridepublic boolean setViewValue(View view, Object data, String textRepresentation){if(view instanceof ImageView && data instanceof Bitmap){ImageView imageview=(ImageView)view;Bitmap bitmap=(Bitmap)data;imageview.setImageBitmap(bitmap);return true;}return false;}
}

再给simpleadapter设置viewbinder

List<Map<String,Object>> arraylist_bookmark=new ArrayList<Map<String,Object>>();Map<String,Object> item_bookmark=new HashMap<String,Object>();item_bookmark.put("bookmark_title","百度一下");item_bookmark.put("bookmark_favicon",bitmap);arraylist_bookmark.add(item_bookmark);SimpleAdapter simpleAdapter=new SimpleAdapter(MainActivity.this ,arraylist_bookmark,R.layout.layout_bookmark_item,new String[]{"bookmark_title","bookmark_favicon"},new int[]{R.id.bookmark_title,R.id.bookmark_favicon});simpleAdapter.setViewBinder(new viewbinder_bookmark());listview_bookmark=(ListView)findViewById(R.id.listview_bookmark);listview_bookmark.setAdapter(simpleAdapter);
