分页加载在程序开发中是必备的，但是我们实现这个功能并不仅仅为了美观，用户体验也是很重要的，爱站技术频道下面就带大家了解Android开发中实现分页效果的简单步骤，感兴趣的小伙伴们参考看看吧！

具体内容如下

1.实现分页最主要的就是封装分页代码，然后在按钮里实现相关的操作

/**

* 分页工具

*

* @Project App_Page

* @Package com.android.dividepage

* @author chenlin

* @version 1.0

* @Date 2012年6月2日

* @Note TODO

* @param */

public class PageHelper{

private ListallData; // 所有数据

private int perPage = 10; // 每页条目

private int currentPage = 1;// 当前页

private int pageNum = 1; // 页码

private ListchildData;// 子数据

private int allNum;// 总共条目

public PageHelper(Listdatas, int perPage) {

this.allData = datas;

if (perPage > 0)

this.perPage = perPage;

// 如果数据大于10条

if (allData != null && allData.size() > perPage) {

childData = allData.subList(0, perPage - 1);

}

allNum = allData.size();

// 如果总数能除断perPage，页数就是余数，否则+1

pageNum = allNum % perPage == 0 ? (allNum / perPage) : (allNum / perPage + 1);

}

public int getCount() {

return this.allNum;

}

public int getCurrentPage() {

return this.currentPage;

}

public int getPageNum() {

return this.pageNum;

}

public int getPerPage() {

return this.perPage;

}

public void gotoPage(int n) { // 页面跳转

currentPage = n > pageNum ? pageNum : (n 1;

}

public void headPage() {// 第一页

currentPage = 1;

}

public void lastPage() {// 最后一页

currentPage = pageNum;

}

public void nextPage() {// 下一页

currentPage = hasNextPage() ? currentPage + 1 : pageNum;

}

public void prePage() {// 前一页

currentPage = hasPrePage() ? currentPage - 1 : 1;

}

public void setPerPage(int perPage) {// 设置上一页面

this.perPage = perPage;

}

/**

* 获得当前数据

* @return

*/

public ListcurrentList() {

if (currentPage == 1) {

childData = allData.subList(0, perPage);

} else if (currentPage == pageNum) {

childData = allData.subList(perPage * (pageNum - 1), allNum);

} else {

childData = allData.subList(perPage * (currentPage - 1), perPage * currentPage);

}

return childData;

}

public void setCurrentPage(int currentPage) {

this.currentPage = currentPage;

}

}

2、主页里我根据tab标签把按钮设置进去，然后在click里方法读取，最后根据tag标签就可判断是哪个按钮点击了

/**

* 分页主页

* @Project App_Page

* @Package com.android.dividepage

* @author chenlin

* @version 1.0

* @Date 2012年6月2日

* @Note TODO

*/

public class MainActivity extends Activity implements OnClickListener {

private ListView mListView;

//分页按钮

private Button mBtnPrePage, mBtnNextPage, mBtnPreItem, mBtnNextItem;

//显示分页信息

private TextView mTvPageNo;

//数据实现

private PageHelpermPageDaoImpl;

private DataAdapter mAdapter;

private ListmDatas;

//被选着的索引

private int selectIndex = 0;

private static final int PREPAGE = 0;

private static final int NEXTPAGE = 1;

private static final int PREITEM = 2;

private static final int NEXTITEM = 3;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

initViews();

initDatas();

}

private void initDatas() {

//从资源文件里读数据

mDatas = Arrays.asList(getResources().getStringArray(R.array.channellist));

//每次读8条数据

mPageDaoImpl = new PageHelper(mDatas, 8);

mAdapter = new DataAdapter(this, mPageDaoImpl.currentList());

mListView.setAdapter(mAdapter);

//设置当前页码与总页码

mTvPageNo.setText(mPageDaoImpl.getCurrentPage() + " / " + mPageDaoImpl.getPageNum());

}

private void initViews() {

mListView = (ListView) findViewById(R.id.page_list);

mBtnPrePage = (Button) findViewById(R.id.pre_page);

mBtnPrePage.setTag(PREPAGE);

mBtnPrePage.setOnClickListener(this);

mBtnNextPage = (Button) findViewById(R.id.next_page);

mBtnNextPage.setTag(NEXTPAGE);

mBtnNextPage.setOnClickListener(this);

mBtnPreItem = (Button) findViewById(R.id.pre_item);

mBtnPreItem.setTag(PREITEM);

mBtnPreItem.setOnClickListener(this);

mBtnNextItem = (Button) findViewById(R.id.next_item);

mBtnNextItem.setTag(NEXTITEM);

mBtnNextItem.setOnClickListener(this);

mTvPageNo = (TextView) findViewById(R.id.pagenum);

}

@Override

public void onClick(View v) {

final int flag = (Integer) v.getTag();

switch (flag) {

case PREPAGE:// 首页

headPage();

break;

case NEXTPAGE:// 尾页

lastPage();

break;

case PREITEM:// 上一条

prePage();

break;

case NEXTITEM:// 下一条

nextPage();

break;

}

}

private void prePage() {

if (selectIndex == 0) {

if (mPageDaoImpl.getCurrentPage() >= 1) {

mPageDaoImpl.prePage();

}

mAdapter.setData(mPageDaoImpl.currentList());

mListView.setSelection(mAdapter.getCount() - 1);

mTvPageNo.setText(mPageDaoImpl.getCurrentPage() + " / " + mPageDaoImpl.getPageNum());

} else {

return;

}

}

private void nextPage() {

if (mPageDaoImpl.getCurrentPage()

3、适配器代码，太简单了，我就不说了

public class DataAdapter extends BaseAdapter {

private Context mContext;

private ListmDatas;

public DataAdapter(Context context, Listdatas) {

this.mContext = context;

this.mDatas = datas;

}

@Override

public int getCount() {

return mDatas == null ? 0 : mDatas.size();

}

@Override

public Object getItem(int position) {

return mDatas == null ? null : mDatas.get(position);

}

@Override

public long getItemId(int position) {

return position;

}

@Override

public View getView(int position, View convertView, ViewGroup parent) {

ViewHolder mHolder;

if (convertView == null) {

convertView = LayoutInflater.from(mContext).inflate(R.layout.channel_item, parent, false);

mHolder = new ViewHolder();

mHolder.nameView = (TextView) convertView.findViewById(R.id.channel_name);

convertView.setTag(mHolder);

}

mHolder = (ViewHolder) convertView.getTag();

mHolder.nameView.setText(mDatas.get(position));

return convertView;

}

static class ViewHolder {

public TextView nameView;

}

public void setData(Listdatas) {

mDatas = datas;

notifyDataSetChanged();

}

}

以上就是爱站技术频道小编介绍的Android开发中实现分页效果的简单步骤，接下来还是要在项目中操作，不管是什么功能的开发也是值得程序员重视的。
