AndroidPicker的使用

参考：

https://github.com/gzu-liyujiang/AndroidPicker

效果图：

一、添加依赖：

project：build.gradle

allprojects { repositories { jcenter() maven { url "https://jitpack.io"} } }

app：build.gradle

compile 'com.alibaba:fastjson:1.1.55.android' compile('com.github.gzu-liyujiang.AndroidPicker:WheelPicker:1.5.4') { exclude group: 'com.android.support' } // compile('com.github.gzu-liyujiang.AndroidPicker:FilePicker:1.5.4') { // exclude group: 'com.android.support' // } // compile('com.github.gzu-liyujiang.AndroidPicker:ColorPicker:1.5.4') { // exclude group: 'com.android.support' // }

布局：

<?xml version="1.0" encoding="utf-8"?> <LinearLayout 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:orientation="vertical" tools:context="com.example.lenovo.mypicker.MainActivity"> <TextView android:id="@+id/tv_address" android:layout_width="match_parent" android:layout_height="wrap_content" android:gravity="center" android:text="你选择的地址" android:textColor="@color/colorPrimary" android:textSize="25sp" /> <Button android:layout_width="match_parent" android:layout_height="wrap_content" android:onClick="onAddressPicker" android:text="地址选择（包括省级、地级、县级）" /> </LinearLayout>

MainActivity

public class MainActivity extends AppCompatActivity { private TextView tvAddress; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); tvAddress = ((TextView) this.findViewById(R.id.tv_address)); } public void onAddressPicker(View view) { AddressPickTask task = new AddressPickTask(this); // task.setHideProvince(true);//隐藏省，显示市、县 // task.setHideCounty(true);//隐藏县，显示省、市 task.setCallback(new AddressPickTask.Callback() { @Override public void onAddressInitFailed() { ToastUtil.showToast(MainActivity.this, "数据初始化失败"); } @Override public void onAddressPicked(Province province, City city, County county) { String address; if (county == null) { address = province.getAreaName() + city.getAreaName(); ToastUtil.showToast(MainActivity.this, province.getAreaName() + city.getAreaName()); } else { address = province.getAreaName() + city.getAreaName() + county.getAreaName(); ToastUtil.showToast(MainActivity.this, province.getAreaName() + city.getAreaName() + county.getAreaName()); } tvAddress.setText(address); } }); //以下几种格式显示效果相同 // task.execute("广东省", "深圳市", "龙岗区");//设置默认 // task.execute("广东", "深圳", "龙岗");//设置默认 // task.execute("广东省", "深圳", "龙岗");//设置默认 // task.execute("广", "深圳", "龙岗");//设置默认 // task.execute("广", "深", "龙岗");//设置默认 task.execute("广", "深", "龙");//设置默认 } }

AddressPickTask
