项目GitHub地址：https://github.com/YLY221/AddressProject
首先需要在build.gradle中添加以下三个依赖
implementation 'com.github.CymChad:BaseRecyclerViewAdapterHelper:2.9.30'
implementation 'com.google.code.gson:gson:2.8.5'
implementation 'com.android.support:design:28.0.0'第一个依赖的作用是加强版的RecyclerView，它是GitHub上的开源项目，链接：https://github.com/CymChad/BaseRecyclerViewAdapterHelper/blob/master/README-cn.md
根据使用说明，还需要在外层build.gradle添加：
allprojects {
repositories {
...
maven {
url "https://jitpack.io"
}
}
}第二个是Gson解析库，需要对json格式数据进行解析，在这里我就不联网获取地址数据了，我直接在main目录下新建assets文件夹，然后把下面json文件复制到assets文件里面：（由于csdn没有json格式数据，所以你们需要在本地新建文件region.json然后把下面的数据复制到新建的文件里面，放到assets文件夹中）

接着在main_activity.xml中写一个TextView，目的是点击这个TextView之后能够弹出地址选择器，选择地址之后把选择的地址显示在这个TextView上。关于TextView的xml我就不写了，比较简单。点击TextView之后需要弹出地址选择器，这个地址选择器取名叫做AreaPickerView，它是继承自Dialog的。具体代码如下：
import android.content.Context;
import android.content.res.AssetManager;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.TextView;
import com.google.gson.Gson;
import com.google.gson.reflect.TypeToken;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.List;
public class MainActivity extends AppCompatActivity {
private TextView textView;
//以下跟选择地址有关
private AreaPickerView areaPickerView;

private String villageId;
@Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
textView=findViewById(R.id.text_view);
Gson gson = new Gson();
addressBeans = gson.fromJson(getJsonFromAssets(MainActivity.this), new TypeToken<List<AddressBean>>() {
}.getType());
areaPickerView = new AreaPickerView(this, R.style.Dialog, addressBeans);
areaPickerView.setAreaPickerViewCallback(new AreaPickerView.AreaPickerViewCallback() {
@Override
public void callback(int... value) {
i=value;
if (value.length == 4) {
textView.setText(addressBeans.get(value[0]).getLabel() + "-" + addressBeans.get(value[0]).getChildren().get(value[1]).getLabel() + "-" + addressBeans.get(value[0]).getChildren().get(value[1]).getChildren().get(value[2]).getLabel()+"-"+ addressBeans.get(value[0]).getChildren().get(value[1]).getChildren().get(value[2]).getChildren().get(value[3]).getLabel());
villageId=addressBeans.get(value[0]).getChildren().get(value[1]).getChildren().get(value[2]).getChildren().get(value[3]).getValue();
} else{
}
}
});
textView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
showListDialogvillage();
}
});
}
private void showListDialogvillage() {
areaPickerView.setSelect(i);
areaPickerView.show();
}
public static String getJsonFromAssets(Context context) {
StringBuilder stringBuilder = new StringBuilder();
try {
AssetManager assetManager = context.getAssets();
BufferedReader bf = new BufferedReader(new InputStreamReader(
assetManager.open("region.json")));
String line;
while ((line = bf.readLine()) != null) {
stringBuilder.append(line);
}
} catch (IOException e) {
e.printStackTrace();
}
return stringBuilder.toString();
}
}
