第一种:滚动式分页【估计是你想要的那种】

packagecom.yangguangfu.listview;

importandroid.app.ListActivity;

importandroid.os.Bundle;

importandroid.util.Log;

importandroid.view.Gravity;

importandroid.view.View;

importandroid.view.ViewGroup;

importandroid.widget.AbsListView;

importandroid.widget.BaseAdapter;

importandroid.widget.LinearLayout;

importandroid.widget.ListView;

importandroid.widget.ProgressBar;

importandroid.widget.TextView;

importandroid.widget.AbsListView.OnScrollListener;

importandroid.widget.LinearLayout.LayoutParams;

/**

*

*@author阿福

*

*/

publicclassMainActivityextendsListActivityimplementsOnScrollListener{

privatestaticfinalStringTAG="MainActivity";

privatelistViewAdapteradapter=newlistViewAdapter();

privateintlastItem=0;

/**

*设置布局显示为目标有多大就多大

*/

privateLayoutParamsWClayoutParams=newLinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT,LinearLayout.LayoutParams.WRAP_CONTENT);

/**

*设置布局显示目标最大化

*/

privateLayoutParamsFFlayoutParams=newLinearLayout.LayoutParams(LinearLayout.LayoutParams.FILL_PARENT,LinearLayout.LayoutParams.FILL_PARENT);

privateProgressBarprogressBar;

protectedvoidonCreate(BundlesavedInstanceState){

super.onCreate(savedInstanceState);

Log.i(TAG,"onCreate(BundlesavedInstanceState)");

//线性布局

LinearLayoutlayout=newLinearLayout(this);

//设置布局水平方向

layout.setOrientation(LinearLayout.HORIZONTAL);

//进度条

progressBar=newProgressBar(this);

//进度条显示位置

progressBar.setPadding(0,0,15,0);

layout.addView(progressBar,WClayoutParams);

TextViewtextView=newTextView(this);

textView.setText("加载中...");

textView.setGravity(Gravity.CENTER_VERTICAL);

layout.addView(textView,FFlayoutParams);

layout.setGravity(Gravity.CENTER);

LinearLayoutloadingLayout=newLinearLayout(this);

loadingLayout.addView(layout,WClayoutParams);

loadingLayout.setGravity(Gravity.CENTER);

//得到一个ListView用来显示条目

ListViewlistView=getListView();

//添加到脚页显示

listView.addFooterView(loadingLayout);

//

registerForContextMenu(listView);

//

setListAdapter(adapter);

listView.setOnScrollListener(this);

}

publicvoidonScroll(AbsListViewv,intfirstVisibleItem,

intvisibleItemCount,inttotalItemCount){

lastItem=firstVisibleItem+visibleItemCount-1;

System.out.println("lastItem:"+lastItem);

Log.i(TAG,"lastItem:"+lastItem);

}

publicvoidonScrollStateChanged(AbsListViewv,intstate){

if(lastItem==adapter.count

&&state==OnScrollListener.SCROLL_STATE_IDLE){

adapter.count+=10;

adapter.notifyDataSetChanged();

Log.i(TAG,"lastItem:"+lastItem);

}

}

/**

*要用用于生成显示数据

*@author阿福

*

*/

classlistViewAdapterextendsBaseAdapter{

intcount=10;

publicintgetCount(){

Log.i(TAG,"count:"+count);

returncount;

}

publicObjectgetItem(intpos){

Log.i(TAG,"pos:"+pos);

returnpos;

}

publiclonggetItemId(intpos){

returnpos;

}

publicViewgetView(intpos,Viewv,ViewGroupp){

TextViewview=newTextView(MainActivity.this);

view.setText("阿福播放器"+pos);

Log.i(TAG,"entry:"+pos);

view.setTextSize(20f);

view.setHeight(80);

returnview;

}

}

}

按钮式分页:

packagecom.yangguangfu.listview;

importandroid.app.ListActivity;

importandroid.os.Bundle;

importandroid.util.Log;

importandroid.view.Gravity;

importandroid.view.View;

importandroid.view.ViewGroup;

importandroid.widget.AbsListView;

importandroid.widget.BaseAdapter;

importandroid.widget.Button;

importandroid.widget.LinearLayout;

importandroid.widget.ListView;

importandroid.widget.TextView;

importandroid.widget.LinearLayout.LayoutParams;

/**

*

*@author阿福

*

*/

publicclassButtonLoadingActivityextendsListActivity{

privatestaticfinalStringTAG="ButtonLoadingActivity";

privatelistViewAdapteradapter=newlistViewAdapter();

/**

*设置布局显示为目标有多大就多大

*/

privateLayoutParamsWClayoutParams=newLinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT,LinearLayout.LayoutParams.WRAP_CONTENT);

/**

*设置布局显示目标最大化

*/

privateLayoutParamsFFlayoutParams=newLinearLayout.LayoutParams(LinearLayout.LayoutParams.FILL_PARENT,LinearLayout.LayoutParams.FILL_PARENT);

protectedvoidonCreate(BundlesavedInstanceState){

super.onCreate(savedInstanceState);

Log.i(TAG,"onCreate(BundlesavedInstanceState):");

LinearLayoutlayout=newLinearLayout(this);

layout.setOrientation(LinearLayout.HORIZONTAL);

Buttonbutton=newButton(this);

button.setText("点击加载下五条...");

button.setGravity(Gravity.CENTER_VERTICAL);

layout.addView(button,FFlayoutParams);

layout.setGravity(Gravity.CENTER);

LinearLayoutloadingLayout=newLinearLayout(this);

loadingLayout.addView(layout,WClayoutParams);

loadingLayout.setGravity(Gravity.CENTER);

ListViewlistView=getListView();

listView.addFooterView(loadingLayout);

button.setOnClickListener(newButton.OnClickListener()

{@Override

publicvoidonClick(Viewv)

{

adapter.count+=5;

Log.i(TAG,"setOnClickListener:"+adapter.count);

adapter.notifyDataSetChanged();

}

});

setListAdapter(adapter);

}

publicvoidonScrollStateChanged(AbsListViewv,ints){

Log.i(TAG,"onScrollStateChanged(AbsListViewv,ints)");

}

classlistViewAdapterextendsBaseAdapter{

intcount=10;/*startingamount*/

publicintgetCount(){returncount;}

publicObjectgetItem(intpos){returnpos;}

publiclonggetItemId(intpos){returnpos;}

publicViewgetView(intpos,Viewv,ViewGroupp){

TextViewtextView=newTextView(ButtonLoadingActivity.this);

textView.setHeight(80);

textView.setTextSize(20);

textView.setText("阿福播放器"+pos);

Log.i(TAG,"getView:pos:"+pos);

returntextView;

}

}

}
