直接上代码

IaiaiActivity.java:

package com.iaiai.activity;import android.app.ListActivity;import android.os.Bundle;import android.util.Log;import android.view.Gravity;import android.view.View;import android.view.ViewGroup;import android.widget.AbsListView;import android.widget.AbsListView.OnScrollListener;import android.widget.BaseAdapter;import android.widget.LinearLayout;import android.widget.LinearLayout.LayoutParams;import android.widget.ListView;import android.widget.ProgressBar;import android.widget.TextView;/** *  * <p> * Title: IaiaiActivity.java * </p> * <p> * E-Mail: 176291935@qq.com * </p> * <p> * QQ: 176291935 * </p> * <p> * Http: iaiai.iteye.com * </p> * <p> * Create time: 2011-6-26 * </p> *  * @author 丸子 * @version 0.0.1 */public class IaiaiActivity extends ListActivity implements OnScrollListener {private static final String TAG = "IaiaiActivity";private listViewAdapter adapter = new listViewAdapter();private int lastItem = 0;/** * 设置布局显示为目标有多大就多大 */private LayoutParams WClayoutParams = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT,LinearLayout.LayoutParams.WRAP_CONTENT);/** * 设置布局显示目标最大化 */private LayoutParams FFlayoutParams = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.FILL_PARENT,LinearLayout.LayoutParams.FILL_PARENT);private ProgressBar progressBar;protected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);Log.i(TAG, "onCreate(Bundle savedInstanceState)");// 线性布局LinearLayout layout = new LinearLayout(this);// 设置布局 水平方向layout.setOrientation(LinearLayout.HORIZONTAL);// 进度条progressBar = new ProgressBar(this);// 进度条显示位置progressBar.setPadding(0, 0, 15, 0);layout.addView(progressBar, WClayoutParams);TextView textView = new TextView(this);textView.setText("加载中...");textView.setGravity(Gravity.CENTER_VERTICAL);layout.addView(textView, FFlayoutParams);layout.setGravity(Gravity.CENTER);LinearLayout loadingLayout = new LinearLayout(this);loadingLayout.addView(layout, WClayoutParams);loadingLayout.setGravity(Gravity.CENTER);// 得到一个ListView用来显示条目ListView listView = getListView();// 添加到脚页显示listView.addFooterView(loadingLayout);//registerForContextMenu(listView);//setListAdapter(adapter);listView.setOnScrollListener(this);}public void onScroll(AbsListView v, int firstVisibleItem,int visibleItemCount, int totalItemCount) {lastItem = firstVisibleItem + visibleItemCount - 1;System.out.println("lastItem:" + lastItem);Log.i(TAG, "lastItem:" + lastItem);}public void onScrollStateChanged(AbsListView v, int state) {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 */class listViewAdapter extends BaseAdapter {int count = 10;public int getCount() {Log.i(TAG, "count:" + count);return count;}public Object getItem(int pos) {Log.i(TAG, "pos:" + pos);return pos;}public long getItemId(int pos) {return pos;}public View getView(int pos, View v, ViewGroup p) {TextView view = new TextView(IaiaiActivity.this);view.setText("丸子测试数据 " + pos);Log.i(TAG, "entry: " + pos);view.setHeight(50);return view;}}}
