Android仿JD選擇地區

注：您正在查看一篇停止維護的博客，只供借鑑參考，後期會提供kotlin版本的demo

整個對話框是建立在一個DialogFragment上面的，DialogFragment在android 3.0時被引入。是一種特殊的Fragment，用於在Activity的內容之上展示一個模態的對話框。

組成結構：DialogFragment+PagerSlidingTabStrip +ViewPager，使用ViewPager來切換省市區的選擇，PagerSlidingTabStrip 作爲頭部tap展示已選擇的信息，點擊已選中的信息tap可以返回重新選擇。

主結構代碼：

}

在selectDistrict()方法中當用戶選擇完區後會自動關閉對話框並調用回調接口的finish()方法進行回顯

這個回調接口定義在主Activity中

package sad.zzq.com.selectaddressdemo;

import android.os.Bundle;

import android.view.View;

import sad.zzq.com.selectaddressdemo.manager.AddressManager;

public class MainActivity extends AppCompatActivity implements View.OnClickListener{

    //收貨人

    private EditText phoneNum;
    //區縣地址
    @ViewInject(R.id.edit_adress)
    private EditText adress;
    //詳細地址
    @ViewInject(R.id.edit_detail_address)
    private EditText detailAddress;


    private String provinceCode ;
    private String cityCode;
    private String areaCode;
    private View rootView;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        rootView = LayoutInflater.from(this).inflate(R.layout.activity_main, null);
        setContentView(rootView);
        x.view().inject(this);
        adress.setOnClickListener(this);
    }

    @Override
    public void onClick(View view) {
        if (view.getId() == R.id.edit_adress) {
            SelectAddressPop pop = new SelectAddressPop();
            pop.setSelectAddresFinish(new SelectAddresFinish(){

                @Override
                public void finish(String pCode, String cCode, String aCode) {
                    //選中地址完成
                    provinceCode = pCode;
                    cityCode = cCode;
                    areaCode = aCode;
                    String addr = AddressManager.newInstance().getAddress(pCode, cCode, aCode);
                    adress.setText(addr);
                }
            });
            pop.setAddress(provinceCode,cityCode,areaCode);
            pop.show(getFragmentManager(),"address");
        }
    }

    public interface SelectAddresFinish{
        void finish(String provinceCode, String cityCode, String areaCode);
    }

}

爲了方便項目引入了xutils3.0的框架
