如何在ListView中添加CheckBox

[yxmsw2007]

我自定义了一个ListView布局，想在里面添加一个CheckBox按钮，我遇到了下面的第二个问题，虽然有解决方法但不知道具体怎么做，最好能给个完整的例子，谢谢大家了！
1、ListView item中加入checkbox后onListItemClick 事件无法触发。
原因：checkbox的优先级高于ListItem于是屏蔽了ListItem的单击事件。
解决方案：设置checkbox的android:focusable="false"
2、选择其中的checkbox，当滚动ListView的时候，会出现一些Checkbox选择错位的现象，
原因：为记住Checkbox的选择状态
解决方案：当选择Checkbox的时候，记下其状态，然后在getView方法中进行设置

个人认为可以通过重写一个类继承BaseAdapter来实现你的功能

帮助文档很详细，可以去参考一下，我也没有记住。。。

1.你都给出结果了，还问啥
2.在getview中加入checkbox 的事件，在把checkbox的状态存到数据库中最好的方法

这是我自己实现的一个自定义ListView 点击选择一会弹出一个dialog

public class checkBtnView extends ListActivity {
private List<Map<String,Object>> hashMap;
//CheckBox box1 = (CheckBox)findViewById(R.id.checkBox1);
//CheckBox box2 = (CheckBox)findViewById(R.id.checkBox2);
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
hashMap = getData();
Log.i("debug", "start debuging");
MyAdapter adapter = new MyAdapter(this);
Log.i("debug", "MyAdapter successed");
setListAdapter(adapter);
Log.i("debug", "setListAdapter successed");
}

private List<Map<String, Object>> getData()
{
List<Map<String, Object>> list = new ArrayList<Map<String,Object>>();
Map<String, Object> map = new HashMap<String, Object>();
map.put("title", "NO.1");
//map.put("text", "No.2");
list.add(map);
// TODO Auto-generated method stub
return list;
}

public void showInfo(){
new AlertDialog.Builder(this)
.setTitle("nice")
.setMessage("good day")
.setPositiveButton("ok", new DialogInterface.OnClickListener() {

@Override
public void onClick(DialogInterface dialog, int which)
{
// TODO Auto-generated method stub

}
}).show();


}

public final class ViewHolder{
public TextView title;
public CheckBox box1;
public CheckBox box2;
}

public class MyAdapter extends BaseAdapter{
private LayoutInflater mInflater;
public MyAdapter(Context context) {
// TODO Auto-generated constructor stub
this.mInflater = LayoutInflater.from(context);
}

@Override
public int getCount()
{
// TODO Auto-generated method stub
// this is some debug;
return hashMap.size();
}

@Override
public Object getItem(int position)
{
// TODO Auto-generated method stub
return null;
}

@Override
public long getItemId(int position)
{
// TODO Auto-generated method stub
return 0;
}




@Override
public View getView(int position, View convertView, ViewGroup parent)
{
// TODO Auto-generated method stub
ViewHolder holder = null;
if (holder == null)
{
Log.i("MyAdapter debug", "start");
holder = new ViewHolder();
Log.i("MyAdapter", "set convertView");
convertView = mInflater.inflate(R.layout.main, null);
holder.title = (TextView)convertView.findViewById(R.id.textView1);
holder.box1 = (CheckBox)convertView.findViewById(R.id.checkBox1);
holder.box2 = (CheckBox)convertView.findViewById(R.id.checkBox2);

}
else

Log.i("MyAdapter", "run wrong");
}


Log.i("MyAdapter", "setClick");

holder.box1.setOnClickListener(new OnClickListener() {

@Override

自定义adapter试一试

[kkkk11kk]

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView

android:id="@+id/textView1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"></TextView>
<CheckBox
android:text="选择一"
android:id="@+id/checkBox1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"></CheckBox>
<CheckBox
android:text="选择二"
android:id="@+id/checkBox2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"></CheckBox>

</LinearLayout>

这是xml文件 希望对楼主有用

checkbox Click事件 放到 adapter中响应

[foley_liao]

我遇到过这个问题
问题1很好解决：设置 checkbox 为：android:focusable="false 就行
<CheckBox android:id="@+id/list_size"
android:layout_alignParentRight="true" android:layout_width="wrap_content"
android:layout_height="wrap_content" android:focusable="false" android:clickable="false" />

问题2 就不太好说，你可以用一个对象保存每一个listitem的信息，其中就可以保存一项 ischecked
在你的adapter的getview中每次读取的时候设置保存的ischecked 。在listitem的单击事件中也要保存ischecked（如果是通过单击改变checkbox的状态的话） 不知道说明白了没有。

4L没明白我的意思，我遇到的问题是这样的，比如我要群发一条短信，群发对象都从电话本中选择，这就需要用一个List将联系人都显示，当我们选择对象的时候就需要用Checkbox，但是我做出来后出现这样一个问题，假如我有30个联系人，我手机一次只能显示10条记录，当我选中第一个联系人的时候，会连带将第11、21这两个人也选上；下面是我在网上找的解决方法，但我没看明白，请大家帮忙看下。
选择其中的checkbox，当滚动ListView的时候，会出现一些Checkbox选择错位的现象，
原因：为记住Checkbox的选择状态
ListView中的getChildCount()并不总是等于ListAdapter中的数据行数。当手机一屏显示不了所有数据时（需要翻页），getChildCount()就等于手机一屏幕所显示的行数，小于ListAdapter中的数据行数。而ListView的getCount()是与ListAdapter中的数据行数相同。
当光标下移到屏幕最底部，新显示出来的View，最初的3个（不知道为什么是3个），在Adapter中调用getView(int position, View convertView, ViewGroup parent)方法中，会判断convertView为null，而再有新的View就会发现convertView不为空，所以新显示的View其实使用了之前某个View的对象。这就造成了状态可能混乱。比如第一行的checkbox点选时，第11行的也同时会被点选。
解决方案：当选择Checkbox的时候，记下其状态，然后在getView方法中进行设置
代码如下：
Java代码
Object b = (Object ) getItem(position);
if (b != null) {
if(selectedSet.contains(b)){
viewHolder.checkBox.setChecked(true);
}else{
viewHolder.checkBox.setChecked(false);
}
}
