2、中下一行；（4） 先點擊列表選中一行，然后修改上面的信息，再點擊“修改”，則將修改后的信息更新到列表中；（5） 在上面的控件中輸入要查詢的姓名，然后點擊“查詢”，則在下面的列表中選中對應的行。參考界面如下圖：調(diào)試過程及實驗結(jié)果1.添加2.查詢3.修改4. 刪除總結(jié)1. 使用listView顯示數(shù)據(jù)，填充數(shù)據(jù)類型為ArrayList<HashMap<String,String>>,適配器類型選的BaseAdapter。2. 在刪除某一行，讓其選中下一行時，用listView.getChildAt(position).setBackgroundColor(Color.RED

3、);得到下一行的view對象并設置背景顏色3. 用一個全局變量location記錄當前選中行所在的位置。4. 在改變data中得值后要使用 adapter.notifyDataSetChanged();刷新一下數(shù)據(jù)。附錄public class MainActivity extends FragmentActivity InjectView(R.id.ed_name) EditText edName; InjectView(R.id.rb_sex_boy) RadioButton rbSexBoy; InjectView(R.id.rb_sex_gril) RadioButton rbSexG
