Android 地址選擇器，實現省市區三級聯動
阿新 • • 發佈：2019-01-04
最近專案裡面用到了一個地址選擇器，實現現在主流的WheelView滑動選擇，整理了下，做了個Demo.廢話不多說，直接上程式碼：
主佈局：
MainActivity:<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:paddingBottom="@dimen/activity_vertical_margin" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" tools:context="com.example.user.myapplication.MainActivity"> <TextView android:id="@+id/select_address_tv" android:layout_width="match_parent" android:layout_height="wrap_content" android:gravity="center" android:textSize="15sp" android:text="選擇地址" /> </RelativeLayout>
主要的類：package com.example.user.myapplication; import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import android.view.Gravity; import android.view.View; import android.widget.TextView; import android.widget.Toast; public class MainActivity extends AppCompatActivity { private TextView select_address_tv; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); select_address_tv= (TextView) findViewById(R.id.select_address_tv); select_address_tv .setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { ChangeAddressPopwindow mChangeAddressPopwindow = new ChangeAddressPopwindow(MainActivity.this); mChangeAddressPopwindow.setAddress("廣東", "深圳", "福田區"); mChangeAddressPopwindow.showAtLocation(select_address_tv, Gravity.BOTTOM, 0, 0); mChangeAddressPopwindow .setAddresskListener(new ChangeAddressPopwindow.OnAddressCListener() { @Override public void onClick(String province, String city, String area) { // TODO Auto-generated method stub Toast.makeText(MainActivity.this, province + "-" + city + "-" + area, Toast.LENGTH_LONG).show(); select_address_tv.setText(province + city + area); } }); } }); } }
