这里写图片描述

PupupWindow的布局文件

为一个ListView 作为pupup的主体内容

<?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/register_lv_zone"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:divider="#30DDDDDD"
        android:dividerHeight="1dp"
        android:scrollbars="none"
        android:scrollingCache="false"
        />
</LinearLayout>

ListView的item布局文件

作为每一个选项

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:background="@android:color/white"
                android:id="@+id/zone_item_parent"
    >
    <TextView
        android:id="@+id/spinner_address"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_margin="20dp"
        android:textColor="#000"
        />
    <TextView
        android:id="@+id/spinner_zone"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentRight="true"
        android:layout_margin="20dp"
        android:textColor="#000"
        />
</RelativeLayout>

初始化Pupup

//        PopupWindow 的页面布局 包含一个listview
        View view = LayoutInflater.from(getApplicationContext()).inflate(R.layout.item_my_spinner, null);
        mRegister_lv_zone = (ListView) view.findViewById(R.id.register_lv_zone);
//        初始化 popupW
        mPopupWindow = new PopupWindow(RegisterActivity.this);
//        设置高度为 自适应
        mPopupWindow.setHeight(ViewGroup.LayoutParams.WRAP_CONTENT);
        mPopupWindow.setWidth(ScreenUtils.getScreenW(RegisterActivity.this) - UIUtils.getDimen(R.dimen.register_edittext_margin_left) * 2);
//       将view添加到  popup里面
        mPopupWindow.setContentView(view);
        mPopupWindow.setBackgroundDrawable(new PaintDrawable());
        mPopupWindow.setFocusable(true);

设置消失Dismiss的监听

  //        popupWindow消失的监听
        mPopupWindow.setOnDismissListener(new PopupWindow.OnDismissListener() {
            @Override
            public void onDismiss() {
              //  处理你要做的事情
            }
        });

开启popupWindow

mRegisterZone.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {     
                 //设置在那个控件下面显示 mPopupWindow
                mPopupWindow.showAsDropDown(mRegisterZone);
            }
        });

为ListView设置适配器

        MySpinnerArrayAdapter mySpinnerArrayAdapter = new MySpinnerArrayAdapter();
        mRegister_lv_zone.setAdapter(mySpinnerArrayAdapter);
// 设配器 
class MySpinnerArrayAdapter extends BaseAdapter {

        @Override
        public int getCount() {
            return mSpinnerZone.length;
        }

        @Override
        public Object getItem(int position) {
            return mSpinnerZone[position];
        }

        @Override
        public long getItemId(int position) {
            return position;
        }

        @Override
        public View getView(int position, View convertView, ViewGroup parent) {
            ViewHolder viewHolder;
            if (convertView == null) {
                LayoutInflater inflater = LayoutInflater.from(getApplicationContext());
                convertView = inflater.inflate(R.layout.item_spinner, parent, false);
                viewHolder = new ViewHolder(convertView);
                convertView.setTag(viewHolder);
            } else {
                viewHolder = (ViewHolder) convertView.getTag();
            }
            viewHolder.mSpinnerAddress.setText(mSpinnerAddress[position]);
            viewHolder.mSpinnerZone.setText(mSpinnerZone[position]);
            return convertView;
        }

        class ViewHolder {
            TextView mSpinnerAddress;
            TextView mSpinnerZone;
            private final RelativeLayout mZone_item_parent;

            ViewHolder(View view) {
                mSpinnerAddress = (TextView) view.findViewById(R.id.spinner_address);
                mSpinnerZone = (TextView) view.findViewById(R.id.spinner_zone);
                mZone_item_parent = (RelativeLayout) view.findViewById(R.id.zone_item_parent);
            }
        }
    }

可以给ListView设置item点击监听隐藏popup

mRegister_lv_zone.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                mPopupWindow.dismiss();
            }
        });
