最近在做地址管理的功能，新建地址的时候，需要根据后台提供的省市区的数据，让用户进行地址的选择，最近项目比较赶，本来想网上找一个的，可是找了很久都没找到我想要的效果，所以就根据后台提供的数据，弄了一个。
1.先看实现的效果图
QQ截图20190512221706.png
本来数据是根据请求后台接口返回的数据，我这里就不请求后台数据了，直接把请求成功后的数据写死，可是把全国省市区的数据太多，导致报错：字符串数据太长，所以我这里只获取了北京的数据。
2.自定义收货地址选择器
public class AddressSelector extends LinearLayout implements View.OnClickListener{
private int TextSelectedColor = Color.parseColor("#D5A872");
private int TextEmptyColor = Color.parseColor("#333333");
//顶部的tab集合
private ArrayList<Tab> tabs;
//列表的适配器
private AddressAdapter addressAdapter;
private ArrayList<CityInterface> cities;
private OnItemClickListener onItemClickListener;
private OnTabSelectedListener onTabSelectedListener;
private RecyclerView list;
//tabs的外层layout
private LinearLayout tabs_layout;
//会移动的横线布局
private Line line;
private Context mContext;
//总共tab的数量
private int tabAmount = 3;
//当前tab的位置
private int tabIndex = 0;
//分隔线
private View grayLine;
//列表文字大小
private int listTextSize = -1;
//列表文字颜色
private int listTextNormalColor = Color.parseColor("#333333");
//列表文字选中的颜色

//列表icon资源

3.Demo中设置点击按钮打开PopWindow进行地址选择
/**
* 设置弹出PopWindow
* @param v
*/
private void setAddressSelectorPopup(View v) {
int screenHeigh = getResources().getDisplayMetrics().heightPixels;
CommonPopWindow.newBuilder()
.setView(R.layout.pop_address_selector_bottom)
.setAnimationStyle(R.style.AnimUp)
.setBackgroundDrawable(new BitmapDrawable())
.setSize(ViewGroup.LayoutParams.MATCH_PARENT, Math.round(screenHeigh * 0.6f))
.setViewOnClickListener(this)
.setBackgroundDarkEnable(true)
.setBackgroundAlpha(0.7f)
.setBackgroundDrawable(new ColorDrawable(999999))
.build(this)
.showAsBottom(v);
}
@Override
public void getChildView(final PopupWindow mPopupWindow, View view, int mLayoutResId) {
switch (mLayoutResId) {
case R.layout.pop_address_selector_bottom:
ImageView imageBtn = view.findViewById(R.id.img_guanbi);
AddressSelector addressSelector = view.findViewById(R.id.address);
//数据解析
AddressSelectorReq addressSelectorReq = new Gson().fromJson(String.valueOf(response), AddressSelectorReq.class);
//设置默认选择数据
dealWithAddressSelector(addressSelector, addressSelectorReq.getDatas(), mPopupWindow);
imageBtn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
mPopupWindow.dismiss();
}
});
break;
}
}
4.设置选择器默认数据
private void dealWithAddressSelector(AddressSelector addressSelector, final List<AddressSelectorReq.DatasBean>
addressSelectorList, final PopupWindow mPopupWindow) {
final String[] sheng = new String[3];
final ArrayList<ItemAddressReq> itemAddressReqs = getItemAddressSheng(addressSelectorList);
addressSelector.setTabAmount(3);
//设置数据
addressSelector.setCities(itemAddressReqs);
//设置Tab横线的颜色
addressSelector.setLineColor(Color.parseColor("#D5A872"));
//设置Tab文字默认颜色
addressSelector.setTextEmptyColor(Color.parseColor("#000000"));
//设置列表选中文字颜色
addressSelector.setListTextSelectedColor(Color.parseColor("#D5A872"));
//设置Tab文字选中的颜色
addressSelector.setTextSelectedColor(Color.parseColor("#D5A872"));
//设置列表的点击事件回调接口
addressSelector.setOnItemClickListener(new OnItemClickListener() {
@Override
public void itemClick(AddressSelector addressSelector, CityInterface city, int tabPosition, int selecePos) {
switch (tabPosition) {
case 0:
//设置省列表数据
sheng[0] = city.getCityName();
saveId[0] = addressSelectorList.get(selecePos).getDb_id();
childrenBeanXList = addressSelectorList.get(selecePos).getDb_children();
addressSelector.setCities(getItemAddressShi(childrenBeanXList));
break;
case 1:
//设置市列表数据
sheng[1] = city.getCityName();
saveId[1] = childrenBeanXList.get(selecePos).getCb_id();
childrenBeans = childrenBeanXList.get(selecePos).getCb_children();
addressSelector.setCities(getItemAddressQu(childrenBeans));
break;
case 2:
//设置区列表数据
sheng[2] = city.getCityName();
saveId[2] = childrenBeans.get(selecePos).getId();
text_suozaidiqu.setText(sheng[0] + sheng[1] + sheng[2]);
mPopupWindow.dismiss();
break;
}
}
});
//设置顶部tab的点击事件回调
addressSelector.setOnTabSelectedListener(new AddressSelector.OnTabSelectedListener() {
@Override
public void onTabSelected(AddressSelector addressSelector, AddressSelector.Tab tab) {
switch (tab.getIndex()) {
case 0:
addressSelector.setCities(itemAddressReqs);
break;
case 1:
addressSelector.setCities(getItemAddressShi(childrenBeanXList));
break;
case 2:
addressSelector.setCities(getItemAddressQu(childrenBeans));
break;
}
}
@Override
public void onTabReselected(AddressSelector addressSelector, AddressSelector.Tab tab) {
}
});
}
5.将获取的省市区的数据进行分类
/**
* 获取省的数据
*
* @param addressSelectorList
* @return
*/
@NonNull
private ArrayList<ItemAddressReq> getItemAddressSheng(List<AddressSelectorReq.DatasBean> addressSelectorList) {
final ArrayList<ItemAddressReq> itemAddressReqs = new ArrayList<>();
for (int i = 0; i < addressSelectorList.size(); i++) {
ItemAddressReq itemAddressReq = new ItemAddressReq();
itemAddressReq.setAreaAbbName(addressSelectorList.get(i).getDb_areaAbbName());
itemAddressReq.setAreaCode(addressSelectorList.get(i).getDb_areaCode());
itemAddressReq.setAreaEnName(addressSelectorList.get(i).getDb_areaEnName());
itemAddressReq.setAreaType(addressSelectorList.get(i).getDb_areaType());
itemAddressReq.setAreaZip(addressSelectorList.get(i).getDb_areaZip());
itemAddressReq.setAreaName(addressSelectorList.get(i).getDb_areaName());
itemAddressReq.setId(addressSelectorList.get(i).getDb_id());
itemAddressReq.setParentId(addressSelectorList.get(i).getDb_parentId());
itemAddressReqs.add(itemAddressReq);
}
return itemAddressReqs;
}
/**
* 获取市的数据
*
* @return
*/
@NonNull
private ArrayList<ItemAddressReq> getItemAddressShi(List<AddressSelectorReq.DatasBean.ChildrenBeanX> datas) {
final ArrayList<ItemAddressReq> itemAddressReqs = new ArrayList<>();
for (int i = 0; i < datas.size(); i++) {
ItemAddressReq itemAddressReq = new ItemAddressReq();
itemAddressReq.setAreaAbbName(datas.get(i).getCb_areaAbbName());
itemAddressReq.setAreaCode(datas.get(i).getCb_areaCode());
itemAddressReq.setAreaEnName(datas.get(i).getCb_areaEnName());
itemAddressReq.setAreaType(datas.get(i).getCb_areaType());
itemAddressReq.setAreaZip(datas.get(i).getCb_areaZip());
itemAddressReq.setAreaName(datas.get(i).getCb_areaName());
itemAddressReq.setId(datas.get(i).getCb_id());
itemAddressReq.setParentId(datas.get(i).getCb_parentId());
itemAddressReqs.add(itemAddressReq);
}
return itemAddressReqs;
}
/**
* 获取区的数据
*
* @param addressSelectorList
* @return
*/
@NonNull
private ArrayList<ItemAddressReq> getItemAddressQu(List<AddressSelectorReq.DatasBean.ChildrenBeanX.ChildrenBean> addressSelectorList) {
final ArrayList<ItemAddressReq> itemAddressReqs = new ArrayList<>();
for (int i = 0; i < addressSelectorList.size(); i++) {
ItemAddressReq itemAddressReq = new ItemAddressReq();
itemAddressReq.setAreaAbbName(addressSelectorList.get(i).getAreaAbbName());
itemAddressReq.setAreaCode(addressSelectorList.get(i).getAreaCode());
itemAddressReq.setAreaEnName(addressSelectorList.get(i).getAreaEnName());
itemAddressReq.setAreaType(addressSelectorList.get(i).getAreaType());
itemAddressReq.setAreaZip(addressSelectorList.get(i).getAreaZip());
itemAddressReq.setAreaName(addressSelectorList.get(i).getAreaName());
itemAddressReq.setId(addressSelectorList.get(i).getId());
itemAddressReq.setParentId(addressSelectorList.get(i).getParentId());
itemAddressReqs.add(itemAddressReq);
}
return itemAddressReqs;
}
6.设置地址选择器的布局文件
<?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:layout_alignParentBottom="true"
android:background="#fff"
android:orientation="vertical"
android:padding="1dp">
<ImageView
android:id="@+id/img_guanbi"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_marginTop="15dp"
android:layout_marginRight="15dp"
android:src="@drawable/guanbi" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_marginTop="30dp"
android:text="所在区域"
android:textColor="#777777"
android:textSize="16sp" />
<com.showly.ylin.addressselectdemo.addressselector.AddressSelector
android:id="@+id/address"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="70dp" />
</RelativeLayout>
6.总结
到这里就实现了地址选择器的功能，因为后台提供的地址数据可能不一样，所以这里就不把全部数据拿出来了，需要完整数据的也可以Q我。
需要Demo的童鞋可以在公众号回复 “地址选择器”
