RelativeLayout>3.实体类ItemBean：
public class ItemBean {
private String msg;
private boolean isShow; // 是否显示CheckBox
private boolean isChecked; // 是否选中CheckBox
public String getMsg() {
return msg;
}
public void setMsg(String msg) {
this.msg = msg;
}

}

}

}
}
4.自定义Adapter：

public Adapter(List list, Context context) {
this.list = list;
inflater = LayoutInflater.from(context);
}
@Override
public int getCount() {

}
@Override
public Object getItem(int position) {
return null;
}
@Override
public long getItemId(int position) {
return 0;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
holder = new ViewHolder();
convertView = inflater.inflate(R.layout.item, null);
holder.msg = (TextView) convertView.findViewById(R.id.listview_tv);
holder.cb = (CheckBox) convertView.findViewById(R.id.listview_select_cb);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
final ItemBean bean = list.get(position);
// 是否是多选状态
if (bean.isShow()) {
holder.cb.setVisibility(View.VISIBLE);
} else {
holder.cb.setVisibility(View.GONE);
}
holder.msg.setText(bean.getMsg());
holder.cb.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
if (isChecked) {
bean.setChecked(true);
} else {
bean.setChecked(false);
}
// 回调方法，将Item加入已选
onShowItemClickListener.onShowItemClick(bean);
}
});
// 必须放在监听后面
holder.cb.setChecked(bean.isChecked());
return convertView;
}
static class ViewHolder {
TextView msg;
CheckBox cb;
}
public interface OnShowItemClickListener {
public void onShowItemClick(ItemBean bean);
}
public void setOnShowItemClickListener(OnShowItemClickListener onShowItemClickListener) {
this.onShowItemClickListener = onShowItemClickListener;
}
} 5.MainActivity：

} 6.在res下新建文件夹anim
（1）新建动画operate_in.xml:
<translate
xmlns:android="http://schemas.android.com/apk/res/android"
android:fromYDelta="100%"
android:toYDelta="0"
android:duration="500">
translate>（2）新建动画operate_out.xml:
<translate
xmlns:android="http://schemas.android.com/apk/res/android"
android:fromYDelta="0"
android:toYDelta="100%"
android:duration="500">
