CheckBox本为复选框,仍然可以当单选框用

自定义ListView item中包含一个textview 和checkbox,checkbox选中级别高于item,故在xml中进行屏蔽

单选方法:(该方法同样适用于radiobutton)

main.xml

GroupAdapter.java

public class GroupAdapter extends BaseAdapter {  

private Activity activity;//上下文  private ArrayListlist;

private LayoutInflater inflater=null;//导入布局

private int temp=-1;

this.activity = context;

this.list = list;

inflater=LayoutInflater.from(context);

}

@Override

public int getCount() {

return list.size();

}

@Override

public Object getItem(int position) {

return list.get(position);

}

@Override

public long getItemId(int position) {

// TODO Auto-generated method stub

return position;

}

//listview每显示一行数据,该函数就执行一次

@Override

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

ViewHolder holder=null;

if (convertView==null) {//当第一次加载ListView控件时  convertView为空

convertView=inflater.inflate(R.layout.group_item_view, null);//所以当ListView控件没有滑动时都会执行这条语句

holder=new ViewHolder();

holder.tv=(TextView)convertView.findViewById(R.id.item_tv);

holder.cb=(CheckBox)convertView.findViewById(R.id.item_cb);

convertView.setTag(holder);//为view设置标签

}

else{//取出holder

holder=(ViewHolder) convertView.getTag();//the Object stored in this view as a tag

}

//设置list的textview显示

holder.tv.setTextColor(Color.WHITE);

holder.tv.setText(list.get(position));

// 根据isSelected来设置checkbox的选中状况

holder.cb.setId(position);//对checkbox的id进行重新设置为当前的position

holder.cb.setOnCheckedChangeListener(new OnCheckedChangeListener() {

//把上次被选中的checkbox设为false

@Override

public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {

if(isChecked){//实现checkbox的单选功能,同样适用于radiobutton

if(temp!=-1){

//找到上次点击的checkbox,并把它设置为false,对重新选择时可以将以前的关掉

CheckBox tempCheckBox=(CheckBox)activity.findViewById(temp);

if(tempCheckBox!=null)

tempCheckBox.setChecked(false);

}

temp=buttonView.getId();//保存当前选中的checkbox的id值

}

}

});

//System.out.println("temp:"+temp);

//System.out.println("position:"+position);

if(position==temp)//比对position和当前的temp是否一致

holder.cb.setChecked(true);

else

holder.cb.setChecked(false);

return convertView;

}

static class ViewHolder {

TextView tv;

CheckBox cb;

}

}

listview checkbox实现多选框

MainAcitvity.java

GroupAdapter.java

public class GroupAdapter extends BaseAdapter {  

private Context context;//上下文  

private ArrayListlist;  //控制CheckBox选中情况  

private static HashMapisSelected;  

private LayoutInflater inflater=null;//导入布局      

public GroupAdapter(Context context, ArrayListlist) {    

this.context = context;    this.list = list;    

inflater=LayoutInflater.from(context);    

isSelected=new HashMap();    

initData();  } 

 private void initData(){//初始化isSelected的数据    

for(int i=0;igetIsSelected(){    return isSelected;  }  

public static void setIsSelected(HashMapisSelected){

GroupAdapter.isSelected=isSelected;

}

}
