Android使用TableLayout动态布局实例

有图有易做图,请先看效果截图:

实现主要功能:
* 1.使用TableLayout动态布局展示,可动态添加和删除.
* 2.初始化时显示动态展示,初始化的数据改造后可来自数据库.
* 3.重置时到初始化状态.
* 4.保存时去重检查,参见代码中去重算法.
首先,建立实体类:
[java]
package tgb.lk.tablelayout;

public class Dict {

 private int id;
 private String name;
 private int orders;
 private String desc;
 private int types;

 //get,set方法.

 @Override
 public String toString() {
 return "Dict [id=" + id + ", name=" + name + ", orders=" + orders
 + ", types=" + types + "]";
 }

}

其次,建立数据层方法接口:
[java]
package tgb.lk.tablelayout;

import java.util.ArrayList;
import java.util.List;

import android.content.Context;

public class DictDaoImpl {

 public DictDaoImpl(Context context) {

 }

 public boolean isExist() {
 return false;
 }

 public List<Dict> getDictItem(String dictId) {
 String[] dicts = new String[] { "华东", "华南", "华北", "华中", "西南", "东北" };
 List<Dict> retList = new ArrayList<Dict>();
 for (int j = 0; j < dicts.length; j++) {
 Dict dict = new Dict();
 dict.setName(dicts[j]);
 dict.setId(j);
 dict.setOrders(j);
 dict.setTypes(1000);
 retList.add(dict);
 }
 return retList;
 }

 public long insert(Dict entity) {
 return 1L;
 }

 public void delete(int id) {
 }

 public void update(Dict entity) {
 }

 public Dict get(Object id) {
 Dict dict = new Dict();
 dict.setId(1);
 dict.setName("华东");
 dict.setOrders(1);
 dict.setTypes(1000);
 return dict;
 }

 public void delete(Integer... ids) {
 }
}

然后,建立layout布局dict_item.xml:
[html]
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
 android:layout_width="fill_parent"
 android:layout_height="wrap_content"
 android:scrollbars="none" >

 <LinearLayout
 android:id="@+id/dictLayout"
 android:layout_width="fill_parent"
 android:layout_height="fill_parent"
 android:orientation="vertical"
 android:scrollbars="" >

 <TextView
 android:id="@+id/title"
 android:layout_width="fill_parent"
 android:layout_height="wrap_content"
 android:text="业务字典管理" />

 <LinearLayout
 android:layout_width="fill_parent"
 android:layout_height="wrap_content"
 android:orientation="horizontal" >

 <TextView
 android:layout_width="80dp"
 android:layout_height="wrap_content"
 android:text="名称:" />

 <EditText
 android:id="@+id/name"
 android:layout_width="200dp"
 android:layout_height="wrap_content"
 android:hint="请输入业务字典名称"
 android:maxLength="20"
 android:singleLine="true" />
 </Linear
