解决 listview 人工设置选择值 setSelection(position) 无效

貌似 人工设置 Listview中某一项为 选中， 使用

setSelection(position)无效。

查了一下， 需要在 适配器里解决

package zms.zte2014.mydrawlayout1.myadapter;

import java.util.List;

import zms.zte2014.mydrawlayout1.R;

import zms.zte2014.mydrawlayout1.bean.MenuInfo;

import android.content.Context;

import android.view.LayoutInflater;

import android.view.View;

import android.view.ViewGroup;

import android.widget.BaseAdapter;

import android.widget.ImageView;

import android.widget.LinearLayout;

import android.widget.TextView;

public class Myadapter5 extends BaseAdapter {

private List<MenuInfo> userlist;

private Context context;

private LayoutInflater inflater;

//当前所在行， 如果nowpos不设初始值的话 ，默认第0个会选中

private static int nowpos=10000;

public final class ListItemView { // 自定义控件集合

public TextView menuname;

public ImageView menuimg;

public LinearLayout menulay;

}

public Myadapter5(Context context, List<MenuInfo> users) {

super();

this.context = context;

userlist = users;

}

@Override

public int getCount() {

return userlist.size();

}

@Override

public Object getItem(int position) {

// TODO Auto-generated method stub

return userlist.get(position);

}

@Override

public long getItemId(int position) {

return position;

}

public void setSelected(int setpos) {

nowpos = setpos;

notifyDataSetChanged();

}

@Override

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

// 自定义视图

ListItemView listItemView = null;

if (convertView == null) {

listItemView = new ListItemView();

// 获取list_item布局文件的视图

inflater = LayoutInflater.from(parent.getContext());

convertView = inflater.inflate(R.layout.list_items, null);

// 获取控件对象

// listItemView.image =

// (ImageView)convertView.findViewById(R.id.imageItem);

listItemView.menuimg = (ImageView) convertView

.findViewById(R.id.menu_img);

listItemView.menuname = (TextView) convertView

.findViewById(R.id.menu_name);

MenuInfo MenuInfo = userlist.get(position);

listItemView.menuname.setText(MenuInfo.getName());

listItemView.menuimg.setImageDrawable(context.getResources().getDrawable(R.drawable.ic_drawer));

convertView.setTag(listItemView);

} else {

listItemView = (ListItemView) convertView.getTag();

}

listItemView.menulay=(LinearLayout)convertView.findViewById(R.id.menu_lay);

listItemView.menulay.setBackgroundResource(R.drawable.actionbar_item_pressed);

if(position==nowpos)

{

listItemView.menulay.setBackgroundResource(R.drawable.actionbar_item_normal);

}

return convertView;

}

}

在 listvew itemonclick里

menuListView.setOnItemClickListener(new OnItemClickListener() {

@Override

public void onItemClick(AdapterView<?> parent, View view,

int position, long id) {

listViewAdapter.setSelected(nowItem);

}

});
