类似各种app内的城市选择

github 地址：http://www.jianshu.com/p/b469c6f02754

依赖：

compile 'com.zaaach:citypicker:1.1'

這个是效果图，最近在github 上看到的实现他很简单，添加依赖和权限几行代码就可以实现這个功能

private static final int REQUEST_CODE_PICK_CITY = 233;
private TextView resultTV;

resultTV = (TextView) findViewById(R.id.tv_result);
findViewById(R.id.btn_select).setOnClickListener(new View.OnClickListener() {@Override
    public void onClick(View v) {startActivityForResult(new Intent(MainActivity.this, CityPickerActivity.class),REQUEST_CODE_PICK_CITY);}
});

通过onActivityResult 返回选择的那个城市

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {if (requestCode == REQUEST_CODE_PICK_CITY && resultCode == RESULT_OK){if (data != null){String city = data.getStringExtra(CityPickerActivity.KEY_PICKED_CITY);resultTV.setText("当前选择：" + city);}}
}

要实现定位效果需要去开发平台申请相应的key

<activity
    android:name="com.zaaach.citypicker.CityPickerActivity"
    android:screenOrientation="portrait"
    android:theme="@style/CityPicker.NoActionBar"
    android:windowSoftInputMode="stateHidden|adjustPan" /><meta-data
    android:name="com.amap.api.v2.apikey"
    android:value="fc827e681a54cc949554a989b55b1e93" />
