android分页查询功能工具类的实现

在一个项目中，常常需要频繁的分页，所以有必要实现一个封装的类来统一管理实现。

首先看下效果图：

 

 

 从上图我们可以看出，这里是将listview中的数据通过底下的分页工具实现分页显示。那我们接下来先贴出代码：

[html]
1、实现布局,这里有两个布局文件，第一个主布局文件main.xml 
 
<RelativeLayout  xmlns:android="http://schemas.android.com/apk/res/android" 
                android:id="@+id/whole_region" 
                android:layout_width="fill_parent" 
                android:layout_height="fill_parent" 
                android:orientation="vertical" > 
 
                <HorizontalScrollView 
                    android:id="@+id/HorizontalScrollView01" 
                    android:layout_width="fill_parent" 
                    android:layout_height="wrap_content" 
                    android:layout_above="@+id/pagebtn" 
                    android:layout_alignParentTop="true" > 
 
                    <LinearLayout 
                        android:layout_width="wrap_content" 
                        android:layout_height="fill_parent" 
                        android:orientation="vertical" > 
 
                        <LinearLayout 
                            android:id="@+id/list_view_title" 
                            android:layout_width="wrap_content" 
                            android:layout_height="wrap_content" 
                            android:orientation="horizontal">                         
                        </LinearLayout> 
 
                        <ListView 
                            android:id="@+id/list" 
                            android:layout_width="wrap_content" 
                            android:layout_height="wrap_content" 
                            android:fadeScrollbars="false" > 
                        </ListView> 
                    </LinearLayout> 
                </HorizontalScrollView> 
 
                <LinearLayout 
                    android:id="@id/pagebtn" 
                    android:layout_width="fill_parent" 
                    android:layout_height="wrap_content" 
                    android:layout_alignParentBottom="true" 
                    android:orientation="vertical" > 
 
                    <include layout="@layout/pagebutton" /> 
                </LinearLayout> 
            </RelativeLayout> 
 
第二个布局文件pagebutton.xml.这个文件嵌套在第一个主文件中。

第二步：新建一个activity,用来显示界面

[java]
public class BuilderList1 extends QueryContextActivity {

        setContentView(R.layout.mynotifylist); 
        setOnClickListener(); 
         
 
        columnWidths = new ArrayList<Integer>(); 
        int weight = this.getWindowManager().getDefaultDisplay().getWidth(); 
        columnWidths.add(weight); 
 
        pagedQueryResultHelper = new PagedQueryResultHelper(this); 
        pagedQueryResultHelper.setTitleCellWidth(columnWidths); 
public class BuilderList1 extends QueryContextActivity {

  columnWidths.add(weight);

  pagedQueryResultHelper = new PagedQueryResultHelper(this);
  pagedQueryResultHelper.setTitleCellWidth(columnWidths);[java]
//这个方法是用来查询数据并显示在LISTVIEW中的，我们这次的重点不在这里，我只列出不详讲，有兴趣的朋友可以自己研究下listview               query();

    }
