listview作为一个常用控件，对listview的操作都应该滚瓜烂熟了。对listview 的数据管理也很熟悉。包括listview的单击，双击，多选删除，完成刷新，添加数据等等。我再次对listview的管理操作写了一个demo。里面包含我说的那些部分操作，根据这个demo可以参考实现自已多更能操作。

1、实现的效果
2、主要的代码
package com.example.listmanage;import java.util.ArrayList;import java.util.LinkedList;import android.os.Bundle;import android.app.Activity;import android.content.Context;import android.view.LayoutInflater;import android.view.View;import android.view.View.OnClickListener;import android.view.ViewGroup;import android.view.Window;import android.widget.AdapterView;import android.widget.AdapterView.OnItemClickListener;import android.widget.BaseAdapter;import android.widget.Button;import android.widget.CheckBox;import android.widget.CompoundButton;import android.widget.CompoundButton.OnCheckedChangeListener;import android.widget.ListView;import android.widget.TextView;import android.widget.Toast;public class MainActivity extends Activity implements OnClickListener ,OnCheckedChangeListener { class ItemStatus { public boolean mIsCheckBoxVisible = false; public boolean mIsCheckBoxSelected = false; } // 记录当前每个工程是否在UI上被选中 private LinkedList<ItemStatus> mItemsExtendData; //listview的数据源 private ArrayList<String> mList; private ListView mListView; //适配器 private ListAdapt mListAdapt; private TextView mtextviewShow; //编辑或者完成 private Button mbuttonEdit; //编辑，显示选择的checkbox private boolean mbStatueShow = false; // private arr @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); requestWindowFeature(Window.FEATURE_NO_TITLE); setContentView(R.layout.activity_main); initData(); initView(); } private void initView() { mListView = (ListView) findViewById(R.id.listView1); mListAdapt = new ListAdapt(this); mListView.setAdapter(mListAdapt); ToolUtil.ReCalListViewHeightBasedOnChildren(mListView); mListView.setOnItemClickListener(new ListItemonClick()); mbuttonEdit = (Button)findViewById(R.id.buttonEdit); mbuttonEdit.setOnClickListener(this); CheckBox cBox = (CheckBox)findViewById(R.id.checkBox1); cBox.setOnCheckedChangeListener(this); TextView textviewDetele = (TextView)findViewById(R.id.textviewDetele); textviewDetele.setOnClickListener(this); mtextviewShow = (TextView)findViewById(R.id.textviewShow); mtextviewShow.setText("已选" + String.valueOf(0) + "项"); findViewById(R.id.layoutBottom).setVisibility(View.GONE); findViewById(R.id.layoutBottomNew).setVisibility(View.VISIBLE); } private void initData() { mList = new ArrayList<String>(); mList.clear(); for (int i = 0; i < 25; i++) { mList.add("第 " + String.valueOf(i) + " 项"); } InitListViewExtendData(); SetShowStatus(false); } //设置每一项是选择checkbox的显示状态 private void SetShowStatus(Boolean bStatueShow) { mbStatueShow = bStatueShow; if (mbStatueShow) { // 遍历listView的数据源,设置部分控件的隐藏和显示 for (ItemStatus ItemData : GetItemsExtendData()) { ItemData.mIsCheckBoxSelected = false; ItemData.mIsCheckBoxVisible = true; } } else { // 遍历listView的数据源,设置部分控件的隐藏和显示 for (ItemStatus ItemData : GetItemsExtendData()) { ItemData.mIsCheckBoxSelected = false; ItemData.mIsCheckBoxVisible = false; } } if (mListAdapt != null) { //使用listview手动计算高度 ToolUtil.ReCalListViewHeightBasedOnChildren(mListView); mListAdapt.notifyDataSetChanged(); } } //listview的单击事件 private class ListItemonClick implements OnItemClickListener{ @Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { CheckBox isSelectedCheckBox = (CheckBox)view.findViewById(R.id.checkBox1); //处理编辑状态的单击选择 if (mbStatueShow) { if (isSelectedCheckBox != null) isSelectedCheckBox.setChecked(!isSelectedCheckBox.isChecked()); return; } Toast.makeText(MainActivity.this, "单击" + String.valueOf(position), Toast.LENGTH_LONG).show(); } } //适配器使用的内部类 class ViewHolder { TextView titleTextView; CheckBox selectCheckBox; } class ListAdapt extends BaseAdapter implements OnCheckedChangeListener { private Context mContext; private LayoutInflater mLayoutInflater; public ListAdapt(Context context) { mContext = context; mLayoutInflater = (LayoutInflater) mContext .getSystemService(Context.LAYOUT_INFLATER_SERVICE); } @Override public int getCount() { return mList.size(); } @Override public Object getItem(int position) { return position; } @Override public long getItemId(int position) { return 0; } @Override public View getView(int position, View convertView, ViewGroup parent) { ViewHolder vHolder = null; if (convertView == null) { vHolder = new ViewHolder(); convertView = mLayoutInflater.inflate( R.layout.activity_main_list_item, null); vHolder.titleTextView = (TextView) convertView .findViewById(R.id.textView1); vHolder.selectCheckBox = (CheckBox) convertView .findViewById(R.id.checkBox1); convertView.setTag(vHolder); } else { vHolder = (ViewHolder) convertView.getTag(); } vHolder.titleTextView.setText(mList.get(position)); if (GetItemsExtendData().size() != 0) { ItemStatus itemStatus = GetItemsExtendData().get(position); if (itemStatus != null && vHolder.selectCheckBox != null) { vHolder.selectCheckBox.setTag(position); vHolder.selectCheckBox.setOnCheckedChangeListener(this); vHolder.selectCheckBox .setVisibility(itemStatus.mIsCheckBoxVisible == true ? View.VISIBLE : View.INVISIBLE); vHolder.selectCheckBox .setChecked(itemStatus.mIsCheckBoxSelected); } } return convertView; } @Override public void onCheckedChanged(CompoundButton buttonView,boolean isChecked) { Integer nPosition = (Integer) (buttonView.getTag()); GetItemsExtendData().get(nPosition.intValue()).mIsCheckBoxSelected = isChecked; // 获取当前的所有选中项个数 -- 如果数据较多的话,不可以这种方式 int nSelectCount = 0; for (ItemStatus ItemData : GetItemsExtendData()) { if (ItemData.mIsCheckBoxSelected == true) nSelectCount += 1; } mtextviewShow.setText("已选" + String.valueOf(nSelectCount) + "项"); } } // 初始化列表的额外数据 private void InitListViewExtendData() { GetItemsExtendData().clear(); int nItemCount = mList.size(); for (int i = 0; i < nItemCount; i++) { ItemStatus itemData = new ItemStatus(); GetItemsExtendData().add(itemData); } } private LinkedList<ItemStatus> GetItemsExtendData() { if (mItemsExtendData == null) mItemsExtendData = new LinkedList<ItemStatus>(); return mItemsExtendData; } protected ArrayList<Integer> getRemoveCount() { // 获取需要删除的索引数组 ArrayList<Integer> needRemoveItemsIndexArray = new ArrayList<Integer>(); for (int i = 0; i < GetItemsExtendData().size(); i++) { ItemStatus itemData = GetItemsExtendData().get(i); if (itemData.mIsCheckBoxSelected == true) needRemoveItemsIndexArray.add(new Integer(i)); } return needRemoveItemsIndexArray; } @Override public void onClick(View v) { switch (v.getId()) { case R.id.buttonEdit: if (mbStatueShow) { mbuttonEdit.setText("编辑"); SetShowStatus(false); findViewById(R.id.layoutBottom).setVisibility(View.GONE); findViewById(R.id.layoutBottomNew).setVisibility(View.VISIBLE); }else { SetShowStatus(true); mbuttonEdit.setText("完成"); findViewById(R.id.layoutBottomNew).setVisibility(View.GONE); findViewById(R.id.layoutBottom).setVisibility(View.VISIBLE); } break; case R.id.textviewDetele: ArrayList<Integer> needRemoveItemsIndexArray = getRemoveCount(); // 删除指定项 for (int i = needRemoveItemsIndexArray.size() - 1; i >= 0; i--) { mList.remove(needRemoveItemsIndexArray.get(i).intValue()); } InitListViewExtendData(); SetShowStatus(true); break; default: break; } } @Override public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) { switch (buttonView.getId()) { case R.id.checkBox1: if (isChecked) { for (ItemStatus ItemData : GetItemsExtendData()) { ItemData.mIsCheckBoxSelected = true; ItemData.mIsCheckBoxVisible = true; } mtextviewShow.setText("已选" + String.valueOf(mList.size()) + "项"); }else { for (ItemStatus ItemData : GetItemsExtendData()) { ItemData.mIsCheckBoxSelected = false; ItemData.mIsCheckBoxVisible = true; } mtextviewShow.setText("已选" + String.valueOf(0) + "项"); } if (mListAdapt != null) { ToolUtil.ReCalListViewHeightBasedOnChildren(mListView); mListAdapt.notifyDataSetChanged(); } break; default: break; } }}
3、手动计算listview高度工具类
package com.example.listmanage;import android.view.View;import android.view.ViewGroup;import android.widget.ListAdapter;import android.widget.ListView;public class ToolUtil { public static void ReCalListViewHeightBasedOnChildren(ListView listView) { if (listView == null) return; ListAdapter listAdapter = listView.getAdapter(); if (listAdapter == null) return; int nTotalHeight = 0; for (int i = 0; i < listAdapter.getCount(); i++) { View listItem = listAdapter.getView(i, null, listView); listItem.measure(0, 0); nTotalHeight += listItem.getMeasuredHeight(); } ViewGroup.LayoutParams params = listView.getLayoutParams(); params.height = nTotalHeight + (listView.getDividerHeight()*(listAdapter.getCount()-1)); }}源码地址：下载
