AndroidListView自定义CheckBox实现列表项多选功能详解

Android ListView没行加入CheckBox&＃xff0c;实现选择列表&＃xff0c;既可点击复选框进行选中&＃xff0c;也可以点击list一行进行选中&＃xff0c;效果图如下&＃xff1a;

下面贴下主要代码的实现&＃xff1a;

对于列表中复选框&＃xff0c;我们需要在复选框的状态发生变化时&＃xff0c;保存复选框的状态&＃xff0c;不然在拖动列表过程中&＃xff0c;会丢失复选框的状态。

在这里我们采用下面方式保存&＃xff1a;

public class Person implements Serializable{

/**

*

*/

private static final long serialVersionUID &＃61; 1L;

private String userCode;

private String userName;

private boolean checked;//保存复选框的状态

此对象保存的数据对象列表中的每一列。

实现ListView的Adapter类代码如下&＃xff1a;

/**

*

*

*

*

*

*

*

public class DispatchSelectUserAdapter extends BaseAdapter {

private Context mContext;

private List mPersonList;

private int mResource;

private LayoutInflater mInflater;

public DispatchSelectUserAdapter(Context context, List personList,

int resource) {

mContext &＃61; context;

mPersonList &＃61; personList;

mResource &＃61; resource;

mInflater &＃61; LayoutInflater.from(mContext);

}

&＃64;Override

public int getCount() {

return mPersonList.size();

}

&＃64;Override

public Object getItem(int position) {

return mPersonList.get(position);

}

&＃64;Override

public long getItemId(int position) {

return position;

}

&＃64;Override

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

if (convertView &＃61;&＃61; null) {

convertView &＃61; mInflater.inflate(mResource, parent, false);

}

TextView tvUserName &＃61; (TextView) convertView.findViewById(

R.id.dispatch_item_select_user_name);

final CheckBox ckbItem &＃61; (CheckBox) convertView.findViewById(

R.id.dispatch_item_select_user_ckb);

Person person &＃61; mPersonList.get(position);

tvUserName.setText(person.getUserName());

System.out.println(person.getUserName());

ckbItem.setChecked(person.isChecked());

ckbItem.setOnClickListener(new View.OnClickListener() {

&＃64;Override

public void onClick(View v) {

mPersonList.get(position).setChecked(ckbItem.isChecked());//保存checkbox状态至位置对应的列表对象Person中

}

});

person &＃61; null;

return convertView;

}

}在主界面初始化数据&＃xff1a;

/**

*

* Desc:初始化列表数据

* &＃64;param personList

*/

private void initListData(List personList) {

DispatchSelectUserAdapter adapter &＃61; new DispatchSelectUserAdapter(

DispatchSelectUserActivity.this, personList,

R.layout.dispatch_select_user_item);

getListView().setAdapter(adapter);

}ListView中列表点击事件&＃xff1a;

/**

* 列表点击

*/

&＃64;Override

protected void onListItemClick(ListView l, View v, int position, long id) {

super.onListItemClick(l, v, position, id);

CheckBox checkbox &＃61; (CheckBox) v.findViewById(R.id.dispatch_item_select_user_ckb);

checkbox.setChecked(!checkbox.isChecked());

mPersonList.get(position).setChecked(checkbox.isChecked());

}

下面贴下界面设计的XML代码&＃xff1a;

android:focusable&＃61;"false"

这样就可以实现上图中的选择列表效果了&＃xff0c;也可以在title区域添加全选复选框&＃xff0c;点击后&＃xff0c;实现全选效果。
