查询条件样式的PopWindow

popwind在Android项目中用到的非常多今天就写一下我在项目中使用的情况，以后方便使用,下面直接上代码。

当点击城市模块的布局时候响应

ll_city.setOnClickListener(this);

执行以下操作

//城市case R.id.ll_city:    View view = LayoutInflater.from(this).inflate(R.layout.popup_area, null);    lv_city = (ListView) view.findViewById(R.id.lv_area);    initPopwind(view,ll_city);    CityAdapter cityAdapter = new CityAdapter(this, cityList);    lv_city.setAdapter(cityAdapter);    //城市点击事件    lv_city.setOnItemClickListener(new AdapterView.OnItemClickListener() {        @Override        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {            popupWindow.dismiss();            CityAdapter adapter = (CityAdapter) (parent.getAdapter());            //根据左侧一级分类选中情况，更新背景色            adapter.setSelectedPosition(position);            adapter.notifyDataSetChanged();            tv_city.setText(cityList.get(position).getCity_name());            //请求最新数据            city_id = cityList.get(position).getCity_id();            requestData(province_id, city_id, 0);        }    });    break;

初始化popwind，设置popwind的高度为屏幕的百分之60

private void initPopwind(View view, final View ll_view) {    LinearLayout layout = new LinearLayout(PartyActivity.this);    WindowManager wm = (WindowManager)            getSystemService(Context.WINDOW_SERVICE);    LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(            LinearLayout.LayoutParams.MATCH_PARENT, (int) (screenHeight * 0.6));    view.setLayoutParams(params);    layout.addView(view);    layout.setBackgroundColor(Color.argb(60, 0, 0, 0));//设置整个popwind的底色有透明覆盖效果    popupWindow = new PopupWindow(layout, screenWidth, screenHeight);    popupWindow.setFocusable(true);    popupWindow.setBackgroundDrawable(new BitmapDrawable());    popupWindow.setOutsideTouchable(true);    layout.setOnClickListener(new View.OnClickListener() {        @Override        public void onClick(View v) {            popupWindow.dismiss();        }    });    popupWindow.showAsDropDown(ll_view);}

popwind所加载的布局文件，你可以根据自己的需求更改，我需要展示的是城市列表所以写成了listview

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:orientation="vertical" android:layout_width="match_parent"    android:layout_height="match_parent">    <ListView        android:id="@+id/lv_area"        android:layout_width="match_parent"        android:layout_height="match_parent"        android:gravity="center"        android:divider="@color/liner_color_grag"        android:dividerHeight="1dp"        android:background="#fff"/></LinearLayout>

城市listview的adapter适配器

/** * 城市的adapter * Created by wss. */public class CityAdapter extends BaseAdapter{    private Context context;    private List<CityBean> list;    public CityAdapter(Context context, List<CityBean> list){        this.context = context;        this.list = list;    }    @Override    public int getCount() {        return list==null?0:list.size();    }    @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 = LayoutInflater.from(context).inflate(R.layout.right_listview_item, null);            holder.nameTV = (TextView) convertView.findViewById(R.id.right_item_name);            convertView.setTag(holder);        }else{            holder = (ViewHolder) convertView.getTag();        }        holder.nameTV.setText(list.get(position).getCity_name());        return convertView;    }    private int selectedPosition = 0;    public void setSelectedPosition(int selectedPosition) {        this.selectedPosition = selectedPosition;    }    public int getSelectedPosition() {        return selectedPosition;    }    private class ViewHolder{        TextView nameTV;    }}

listview条目的布局文件，我这个写的布局很简单，自己可以根据需要写，如果是布局已经定好，条目固定而且数量有限就可以不用使用listview了，也就不需要adapter和条目的布局文件了。

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:orientation="vertical"    android:layout_width="match_parent"    android:layout_height="45dp"    >    <TextView        android:id="@+id/right_item_name"        android:layout_width="match_parent"        android:layout_height="45dp"        android:textSize="14sp"        android:textColor="@color/province"        android:text="安钢"        android:maxLength="10"        android:ellipsize="end"        android:gravity="center_vertical"        android:background="@color/lv_bg"        android:paddingLeft="10dp"        /></LinearLayout>

popwind代码写完了效果如下：

这个效果需要加上siderbar，下一篇博客会介绍这个功能

popwind效果如上图，希望能帮到大家。
