Android_全国省市区-三级联动 时间选择器

转载请标明出处：http://blog.csdn.net/sh_12345/article/details/52838582

1 在项目中添加依赖：compile 'com.bigkoo:pickerview:2.1.0'

2从网上下载 WheelView   https://github.com/
这里我所用到的有:

ArrayWheelAdapter

OnWheelChangedListener

OnWheelScrollListener

OptionsPopupWindow

ScreenInfo

TimePopupWindow

WheelAdapter

WheelOptions

WheelTime

WheelView

NumericWheelAdapter

3.1 自己写json数据这里是我写的

// 城区数组
ArrayList<String> ProvinceList = new ArrayList<String>();
ArrayList<ArrayList<String>> CityList = new ArrayList<ArrayList<String>>();
ArrayList<ArrayList<ArrayList<String>>> CountyList = new ArrayList<ArrayList<ArrayList<String>>>();

private void getWheelList() {
try {
// 获取json文件输入流
InputStream is = getResources().getAssets().open("china_address.json");

// 将json文件读入为一个字符串
byte[] bytearray = new byte[is.available()];
is.read(bytearray);
String address_json = new
4000
String(bytearray, "UTF-8");

// 将json转化为JSONArray对象,这是所有省的JSONArray
JSONArray jsonArraySheng = new JSONArray(address_json);

// 遍历这个JSONArray对象
for (int i = 0; i < jsonArraySheng.length(); i++) {
// 取出第i个省对象，并将其转化为JSONObject对象
JSONObject jsonObjectSheng = jsonArraySheng.getJSONObject(i);
// 将省的名字存入一维数组
StringBuffer provincename = new StringBuffer(jsonObjectSheng.getString("areaName"));
ProvinceList.add(provincename.toString());
// 存储第i个省的城市名的数组
ArrayList<String> tempj = new ArrayList<String>();
// 存储第i个省的所有城市的城区名的二维数组
ArrayList<ArrayList<String>> tempk = new ArrayList<ArrayList<String>>();
// 取出第i个省对象中的城市数组，并将其转化为JSONArray对象
JSONArray jsonArrayShi = jsonObjectSheng.getJSONArray("cities");
// 遍历第i个省的城市JSONArray
for (int j = 0; j < jsonArrayShi.length(); j++) {
// 取出第i个省的第j个市，并将其转化为JSONObject对象
JSONObject jsonObjectShi = jsonArrayShi.getJSONObject(j);
// 将市的名字存入第i个省的城市名数组
StringBuffer cityname = new StringBuffer(jsonObjectShi.getString("areaName"));
tempj.add(cityname.toString());
// 存储第i个省第j个市的城区名的数组
ArrayList<String> tempkk = new ArrayList<String>();
// 取出第i个省第j个市中的城区数组，并将其转化为JSONArray对象
JSONArray jsonArrayQu = jsonObjectShi.getJSONArray("counties");
// 遍历第i个省第j个市的城区JSONArray
for (int k = 0; k < jsonArrayQu.length(); k++) {
// 第i个省第j个市第k个区
JSONObject jsonObjectQu = jsonArrayQu.getJSONObject(k);
// 名字存入数组
StringBuffer countyname = new StringBuffer(jsonObjectQu.getString("areaName"));
tempkk.add(countyname.toString());
}
// 第i个省第j个市的城区名的数组添加到第i个省的所有城市的城区名的二维数组
tempk.add(tempkk);
}
CityList.add(tempj);
CountyList.add(tempk);
}
} catch (IOException e) {
e.printStackTrace();
} catch (JSONException e) {
e.printStackTrace();
}
}

3.2 对 OptionsPopupWindow 进行初始化

getWheelList();
OptionsPopupWindow popupWindow = new OptionsPopupWindow(ProvincialCityActivity.this);
popupWindow.showAtLocation(textView, Gravity.BOTTOM, 0, 0);//textView
popupWindow.setPicker(ProvinceList, CityList, CountyList, true);
popupWindow.setOnoptionsSelectListener(this);
popupWindow.setCyclic(false);

其中 textView 为你布局文件中的控件，在我的布局文件中为TextView

3.3 重写OptionsPopupWindow中的方法

@Override
public void onOptionsSelect(int options1, int option2, int options3) {
textView.setText(ProvinceList.get(options1) + CityList.get(options1).get(option2) + CountyList.get(options1).get(option2).get(options3));
Toast.makeText(ProvincialCityActivity.this, "" + textView.getText().toString(), Toast.LENGTH_SHORT).show();
}
这样就实现了全国省市区的三级联动

时间的

TYPE四种选择模式，年月日时分，年月日，时分，月日时分(可改变模式)

4.1 OptionsPopupWindow 进行初始化

type = TimePopupWindow.Type.ALL;
TimePopupWindow popupWindow = new TimePopupWindow(TimeActivity.this, type);
popupWindow.showAtLocation(editText, Gravity.BOTTOM, 0, 0);
popupWindow.setOnTimeSelectListener(this);
popupWindow.setCyclic(true);//是否循环

4.2重写 TimePopupWindow 中的onTimeSelect()方法
因为时间的格式为"Wed Oct 19 17:21:00 GMT+08:00 2016"时区格式，所有需要转换

http://www.chengxuyuans.com/Android/83452.html

@Override
public void onTimeSelect(Date date) {
//String str = "Wed Oct 19 17:21:00 GMT+08:00 2016";
SimpleDateFormat sdf = new Simpl
ce31
eDateFormat("EEE MMM ddHH:mm:ss 'GMT' yyyy", Locale.US);
try {
String date1 = sdf.format(date);
Date da = sdf.parse(date1);
if (type == TimePopupWindow.Type.ALL) {//年月日时分
sdf = new SimpleDateFormat("yyyy年MM月dd日HH:mm:ss");
Log.i("TAG", "date1 = " + date);
Log.i("TAG", "sdf.format(date1)-- " + sdf.format(da));
editText.setText(sdf.format(da));
} else if (type == TimePopupWindow.Type.YEAR_MONTH_DAY) {//年月日
sdf = new SimpleDateFormat("yyyy年MM月dd日");
Log.i("TAG", "date1 = " + date);
Log.i("TAG", "sdf.format(date1)-- " + sdf.format(da));
editText.setText(sdf.format(da));
} else if (type == TimePopupWindow.Type.MONTH_DAY_HOUR_MIN) {//月日时分
sdf = new SimpleDateFormat("MM月dd日 HH:mm");
Log.i("TAG", "date1 = " + date);
Log.i("TAG", "sdf.format(date1)-- " + sdf.format(da));
editText.setText(sdf.format(da));
} else if (type == TimePopupWindow.Type.HOURS_MINS) {//时分
sdf = new SimpleDateFormat("HH:mm");
Log.i("TAG", "date1 = " + date);
Log.i("TAG", "sdf.format(date1)-- " + sdf.format(da));
editText.setText(sdf.format(da));
}
} catch (ParseException e) {
e.printStackTrace();
}
}

此外还有一些动画、布局、style等

5 CalendarView 使用

在布局中

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 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"
android:orientation="vertical">

<CalendarView
android:id="@+id/calendar"
android:layout_width="match_parent"
android:layout_height="340dp"
android:layout_marginLeft="10dp"
android:layout_marginRight="10dp"
android:layout_marginTop="40dp" />

</LinearLayout>

private CalendarView calendar;

//年/月/日
private int year;
private int month;
private int day;

calendar = (CalendarView) findViewById(R.id.calendar);

Long nowTime = calendar.getDate();
SimpleDateFormat f = new SimpleDateFormat("yyyy年MM月dd日hh:mm:ss");
String time = f.format(nowTime);
System.out.println("-------------" + time);
calendar.setOnDateChangeListener(new CalendarView.OnDateChangeListener() {

@Override
public void onSelectedDayChange(CalendarView arg0, int arg1,
int arg2, int arg3) {
arg2 = arg2 + 1;
year = arg1;
month = arg2;
day = arg3;
System.out.println("-------------" + arg1 + "-" + arg2 + "-"
+ arg3);
}
});
