在根目录下build中加入
maven { url "https://jitpack.io" }
如：allprojects {
    repositories {
        jcenter()
        maven { url "https://jitpack.io" }
    }
}

需要导包：
compile 'com.github.yekh:CityPicker:v1.0.1'

布局文件：
<?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"    tools:context="com.example.andy.chengshiliebiao.MainActivity">    <Button        android:id="@+id/but"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:text="Hello World!" /></RelativeLayout>

MainActivity方法里的代码：
public class MainActivity extends AppCompatActivity {
private Button but;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        but=(Button)findViewById(R.id.but);
        but.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                CityListActivity.startCityActivityForResult(MainActivity.this);
            }
        });
    }
    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if(requestCode== CityListActivity.REQUEST_CODE&&resultCode==CityListActivity.RESULT_CODE){
            String city = data.getStringExtra(CityListActivity.RESULT_KEY);
            but.setText(city);
        }
    }
}
