含有CheckBOX 的listview控件实现全选全不选的功能

自己手机是华为的，里面有一个安全卫士的安装包管理的功能用的就是含有CheckBOX 的listview控件实现全选全不选的功能，不过自己手机中的可以实现部分选中在界面响应，自己只实现了全选、全不选的功能，部分选中还有待研究。

一下是代码：贴出来方便自己记忆

package com.example.listviewcheckboxdemo;

import java.util.ArrayList;
import java.util.List;

import com.example.listviewcheckboxdemo.R.layout;

import android.os.Bundle;
import android.app.Activity;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.CheckBox;
import android.widget.CompoundButton;
import android.widget.CompoundButton.OnCheckedChangeListener;
import android.widget.ListView;

public class MainActivity extends Activity {
 private ListView lv;
 private ListViewAda adapter;
 private List<Person> lists = new ArrayList<Person>();
 private View v;
 private String title="清除列表";
private   Button cleanBtn;
private CheckBox checked;
 @Override
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);
  initView();

 }

 private void initView() {
  lv = (ListView) findViewById(R.id.listView1);
  fillDataforListView();
  adapter=new ListViewAda(lists,this);   
  v = getLayoutInflater().inflate(R.layout.footer_content, null);
  cleanBtn = (Button) v.findViewById(R.id.button1);
  cleanBtn.setEnabled(false);
  cleanContent(cleanBtn, title);
  checked = (CheckBox) v.findViewById(R.id.checkBox1);
 locationCheckedstate();

  checked.setOnCheckedChangeListener(new OnCheckedChangeListener() {
   
   @Override
   public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
   if(isChecked){
    adapter.isAllChecked(true);
    Log.e("result", "地步checkbox被选中");
    adapter.notifyDataSetChanged();
    cleanBtn.setText(title+lists.size());
    cleanBtn.setEnabled(true);
   }else{
   adapter.isAllChecked(false);
   adapter.notifyDataSetChanged();
   cleanBtn.setText(title);
   cleanBtn.setEnabled(false);
   }
   }
  });

  Log.e("result","========================="+ lists.size());
  if(lists.size()>0){
   addFooterView();
  }
  lv.setAdapter(adapter);
  adapter.notifyDataSetChanged();
 
 }

 private void cleanContent(Button btn, String title) {
  btn.setText(title);
  btn.setOnClickListener(new MyListener());
 }

 class MyListener implements OnClickListener {

  @Override
  public void onClick(View v) {
   lists.clear();
   adapter.notifyDataSetChanged();
   Log.e("result", "数据被清楚===="+lists.size());
  }

 }

 private void addFooterView() {
  lv.addFooterView(v);
 }

 private void fillDataforListView() {
  for (int i = 0; i < 5; i++) {
   String name = "per" + i;
   Person p = new Person(name, 23 + i);
   lists.add(p);
  }
 }

 @Override
 public boolean onCreateOptionsMenu(Menu menu) {
  // Inflate the menu; this adds items to the action bar if it is present.
  getMenuInflater().inflate(R.menu.main, menu);
  return true;
 }
private void locationCheckedstate(){
 Log.e("re", "------------adapter.isContentChecked()-------------"+adapter.isContentChecked());
 if(adapter.isContentChecked()>0&&adapter.isContentChecked()<lists.size()){
  cleanBtn.setEnabled(true);
  checked.setChecked(false);
 }else if(adapter.isContentChecked()==lists.size()){
  cleanBtn.setEnabled(true);
  checked.setChecked(true);
 }
 cleanBtn.setText(title+"("+adapter.isContentChecked()+")");
 adapter.notifyDataSetChanged();
}
}

 

适配器中的代码：

package com.example.listviewcheckboxdemo;

import java.util.ArrayList;
import java.util.List;

import android.content.Context;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.CheckBox;
import android.widget.CompoundButton;
import android.widget.CompoundButton.OnCheckedChangeListener;
import android.widget.TextView;

public class ListViewAda extends BaseAdapter {
private List<Person>lists=new ArrayList<Person>();
private LayoutInflater inflater;
boolean  isCheckedItem=false;
private Context context;
 private List<Person>CheckedItems=new ArrayList<Person>();

 public ListViewAda(List<Person> lists,Context context) {
 super();
 this.lists = lists;
 this.context=context;
 this.inflater = inflater.from(context);
}

 @Override
 public int getCount() {
  if(lists.size()>0) return lists.size();
  return 0;
 }

 @Override
 public Object getItem(int position) {
  return lists.get(position);
 }

 @Override
 public long getItemId(int position) {
  return position;
 }

 @Override
 public View getView(final int position, View convertView, ViewGroup parent) {
  ViewHolder vh=null;
  if(convertView==null){
   vh=new ViewHolder();
   convertView=inflater.inflate(R.layout.ada_layput, null);
   vh.tv_name=(TextView) convertView.findViewById(R.id.textView1);
   vh.tv_age=(TextView) convertView.findViewById(R.id.textView2);
   vh.cb=(CheckBox) convertView.findViewById(R.id.checkBox1);
  convertView.setTag(vh);
  }
  vh=(ViewHolder) convertView.getTag();
  vh.tv_name.setText(lists.get(position).getName());
  vh.tv_age.setText(Integer.toString(lists.get(position).getAge()).toString());
  vh.cb.setChecked(isCheckedItem);
  vh.cb.setOnCheckedChangeListener(new OnCheckedChangeListener() {
   
   @Override
   public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
    if(isChecked)  {
     CheckedItems.add(lists.get(position));
    }else if(!isChecked){
     CheckedItems.remove(lists.get(position));
    }
    }
     
   

  });
  return convertView;
 }
class ViewHolder{
 TextView tv_name,tv_age;
 CheckBox cb;
}
//是否全选
public void isAllChecked(boolean isChecked){
 isCheckedItem=isChecked;
 notifyDataSetChanged();
}
int isContentChecked(){
 Log.e("result", "被选中的个个数="+CheckedItems.size());
 if(CheckedItems.size()>0)return CheckedItems.size();
 return 0;
}
}

 

布局：

布局都很简单，主布局就一个listview控件，尾部布局就一个按钮和一个checkbox控件，就不贴了，
