                    String PRIMARY_SERVICE_CATEGORY = c.getString(TAG_PRIMARY);
                    String SECONDARY_SERVICE_CATEGORY = c.getString(TAG_SECONDARY);
                    
                    HashMap<String, String> list = new HashMap<String, String>();
                    
                    list.put(TAG_NAME, SUPPLIER_NAME);     
                    list.put(TAG_PRIMARY, PRIMARY_SERVICE_CATEGORY);
                    list.put(TAG_SECONDARY, SECONDARY_SERVICE_CATEGORY);
                    detailList.add(list);
                    lv=(ListView) findViewById(R.id.listView1);
                    ListAdapter adapter = new SimpleAdapter(SupplierDetails.this, detailList,R.layout.list_view, new String[] 
                    		{ TAG_NAME, TAG_PRIMARY,TAG_SECONDARY }, new int[] { R.id.name,R.id.primary, R.id.secondary });
                   // Toast.makeText(getApplicationContext(), SUPPLIER_NAME, Toast.LENGTH_SHORT).show();
         
                    lv.setAdapter(adapter);
				}
					
				}
			}
		}catch(JSONException e){
			e.printStackTrace();
		}

推荐答案

您是否告知列表视图数据已更改？

Do you inform the listview the data has changed ?

lv.notifyDataSetChanged();

如果没有尝试在填充循环结束

If not try adding doing that at the end of the populate loop
