PopupWindow选择地区

首先是xml文件

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context="com.example.dell.pop.MainActivity">

    <LinearLayout
        android:orientation="horizontal"
        android:layout_width="match_parent"
        android:layout_height="50dp">
        <TextView
            android:layout_width="100dp"
            android:layout_height="50dp"
            android:layout_gravity="center"
            android:text="城市："
            />
        <TextView
            android:id="@+id/text"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:onClick="text"
            />
    </LinearLayout>
</LinearLayout>

然后就是mainactivity里面的代码

import android.content.Context;
import android.graphics.Color;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.view.inputmethod.InputMethodManager;
import android.widget.TextView;

import com.lljjcoder.citypickerview.widget.CityPicker;

/**

public class MainActivity extends AppCompatActivity {


    private TextView text;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        text = (TextView)findViewById(R.id.text);
    }
    public void text(View v){
        InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
        if (imm.isActive()) {
            imm.hideSoftInputFromWindow(v.getWindowToken(),
                    InputMethodManager.HIDE_NOT_ALWAYS);
            selectAddress();//调用CityPicker选取区域
        }
    }
    private void selectAddress() {
        CityPicker cityPicker = new CityPicker.Builder(MainActivity.this)
                .textSize(14)
                .title("地址选择")
                .titleBackgroundColor("#FFFFFF")
                // .titleTextColor("#696969")
                .confirTextColor("#696969")
                .cancelTextColor("#696969")
                .province("江苏省")
                .city("常州市")
                .district("天宁区")
                .textColor(Color.parseColor("#000000"))
                .provinceCyclic(true)
                .cityCyclic(false)
                .districtCyclic(false)
                .visibleItemsCount(7)
                .itemPadding(10)
                .onlyShowProvinceAndCity(false)
                .build();
        cityPicker.show();
        //监听方法，获取选择结果
        cityPicker.setOnCityItemClickListener(new CityPicker.OnCityItemClickListener() {
            @Override
            public void onSelected(String... citySelected) {
                //省份
                String province = citySelected[0];
                //城市
                String city = citySelected[1];
                //区县（如果设定了两级联动，那么该项返回空）
                String district = citySelected[2];
                //邮编
                String code = citySelected[3];
                //为TextView赋值
                text.setText(province.trim() + "-" + city.trim() + "-" + district.trim());
            }
        });
    }
}

最后就是一个依赖包：

compile 'liji.library.dev:citypickerview:0.7.0'
