Android 省，市，区选择权

需要WheelView基础控件自行扩展实现逻辑，可直接添加基础控件库，Gradle 依赖：

 compile 'com.contrarywind:wheelview:4.0.9'

布局：

 <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:orientation="vertical">      <include         layout="@layout/include_pickerview_topbar"         android:layout_width="match_parent"         android:layout_height="@dimen/pickerview_topbar_height" />      <LinearLayout         android:id="@+id/optionspicker"         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:background="@android:color/white"         android:orientation="horizontal">          <com.contrarywind.view.WheelView             android:id="@+id/options1"             android:layout_width="0dp"             android:layout_height="wrap_content"             android:layout_weight="1" />          <com.contrarywind.view.WheelView             android:id="@+id/options2"             android:layout_width="0dp"             android:layout_height="wrap_content"             android:layout_weight="1" />          <com.contrarywind.view.WheelView             android:id="@+id/options3"             android:layout_width="0dp"             android:layout_height="wrap_content"             android:layout_weight="1" />     </LinearLayout>   </LinearLayout>

初始化PopWindow:

   private void initPopwindow() {          popupWindow = new PopupWindow(this);         LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);         View mMenuView = inflater.inflate(R.layout.my_pickerview_options, null);          Button btnCancel, btnSubmit;          options1 = mMenuView.findViewById(R.id.options1);         options2 = mMenuView.findViewById(R.id.options2);         options3 = mMenuView.findViewById(R.id.options3);         btnCancel = mMenuView.findViewById(R.id.btnCancel);         btnSubmit = mMenuView.findViewById(R.id.btnSubmit);         btnCancel.setTextColor(ContextCompat.getColor(RegisterShopActivity.this, R.color.colorCancel));         btnSubmit.setTextColor(ContextCompat.getColor(RegisterShopActivity.this, R.color.colorSub));         btnSubmit.setOnClickListener(new View.OnClickListener() {             @Override             public void onClick(View v) {                  String opt1tx = mOptionsItems1.size() > 0 ?                         mOptionsItems1.get(options1.getCurrentItem()) : "";                 String opt2tx = mOptionsItems2.size() > 0 ?                         mOptionsItems2.get(options2.getCurrentItem()) : "";                 String opt3tx = mOptionsItems3.size() > 0 ?                         mOptionsItems3.get(options3.getCurrentItem()) : "";                 String tx = opt1tx + opt2tx + opt3tx;                 tvShopAddress.setText(tx);                 tvShopAddress.setTextColor(ContextCompat.getColor(RegisterShopActivity.this, R.color.colorText));                 isSelectAdress = true;                 popupWindow.dismiss();             }         });         btnCancel.setOnClickListener(new View.OnClickListener() {             @Override             public void onClick(View v) {                 popupWindow.dismiss();             }         });          options1.setCyclic(false);         options2.setCyclic(false);         options3.setCyclic(false);         options1.setDividerColor(Color.BLACK);         options2.setDividerColor(Color.BLACK);         options3.setDividerColor(Color.BLACK); //        options1.setIsOptions(true); //        options2.setIsOptions(true); //        options3.setIsOptions(true);          options1.setAdapter(new ArrayWheelAdapter(mOptionsItems1));         options2.setAdapter(new ArrayWheelAdapter(mOptionsItems2));         options3.setAdapter(new ArrayWheelAdapter(mOptionsItems3));          options1.setTextSize(20);         options2.setTextSize(20);         options3.setTextSize(20);          options1.setOnItemSelectedListener(new OnItemSelectedListener() {             @Override             public void onItemSelected(int index) { //                Toast.makeText(RegisterShopActivity.this, "" + mOptionsItems1.get(index), Toast.LENGTH_SHORT).show();                 int province_id = province.get(index).getProvince_id();                 getCity(province_id + "");             }         });         options2.setOnItemSelectedListener(new OnItemSelectedListener() {             @Override             public void onItemSelected(int index) { //                Toast.makeText(RegisterShopActivity.this, "" + mOptionsItems2.get(index), Toast.LENGTH_SHORT).show();                 long city_id = city.get(index).getCity_id();                 getCounty(city_id + "");             }         });           popupWindow.setContentView(mMenuView);         popupWindow.setWidth(LinearLayout.LayoutParams.MATCH_PARENT);         popupWindow.setHeight(LinearLayout.LayoutParams.WRAP_CONTENT);         ColorDrawable dw = new ColorDrawable(0x000000);         popupWindow.setBackgroundDrawable(dw);         popupWindow.setFocusable(true);         popupWindow.setOutsideTouchable(true);         popupWindow.setAnimationStyle(R.style.picker_view_slide_anim);          // 设置popupWindow取消的点击事件，即popupWindow消失后，屏幕的透明度，全透明，就回复原状态         popupWindow.setOnDismissListener(new PopupWindow.OnDismissListener() {             @Override             public void onDismiss() {                 WindowUtil.backgroundAlpha(RegisterShopActivity.this, 1f);             }         });     }

   private void showPopwindow() {          popupWindow.showAtLocation(rlBankInfo,                 Gravity.BOTTOM | Gravity.CENTER_HORIZONTAL, 0, 0);         WindowUtil.backgroundAlpha(this, 0.4f);         llDetailAddress.setVisibility(View.VISIBLE);     }

设置数据：

                                 activity.options1.setAdapter(new ArrayWheelAdapter(activity.mOptionsItems1));                                 activity.options1.setCurrentItem(0);

这里我的省，市，区的数据都是服务器请求获取的。获取省数据时，需要获取市的数据。获取市的数据后，需要获取区的数据。每次滑动省，市时，需要获取数据。
