概述
首先,通过之前用过的百度地图,实现定位功能;首先去百度开放云申请密钥,这里就不说明申请过程了,不懂得可以百度一下。
申请完密钥后,需要去声明Activity的地方添加上下面的语句:
<meta-data
android:name="com.baidu.lbsapi.API_KEY"
android:value="dGozMoOnqaOgcpaj3f3NBtxh" />
Value值 即填写申请的密钥;
声明定位:
// 定位相关
public LocationClient mLocationClient = null;
public BDLocationListener myListener = new MyLocationListener();
mLocationClient = new LocationClient(getApplicationContext()); // 声明LocationClient类
mLocationClient.registerLocationListener(myListener); // 注册监听函数
LocationClientOption option = new LocationClientOption();
option.setOpenGps(true);// 打开gps
option.setCoorType("bd09ll");// 返回的定位结果是百度经纬度,默认值gcj02
// option.setScanSpan(5000);//设置发起定位请求的间隔时间为5000ms,如果不设置,默认只定位一次
option.setIsNeedAddress(true);// 返回的定位结果包含地址信息
option.setNeedDeviceDirect(true);// 返回的定位结果包含手机机头的方向
option.setLocationMode(com.baidu.location.LocationClientOption.LocationMode.Hight_Accuracy);// 设置定位模式
option.setProdName(getPackageName());
mLocationClient.setLocOption(option);
mLocationClient.start();
定义监听器:
// 定位
public class MyLocationListener implements BDLocationListener {
@Override
public void onReceiveLocation(BDLocation location) {
if (location == null)
return;
StringBuffer sb = new StringBuffer(256);
sb.append("time : ");
sb.append(location.getTime());
sb.append("nerror code : ");
sb.append(location.getLocType());
sb.append("nlatitude : ");
sb.append(location.getLatitude());
sb.append("nlontitude : ");
sb.append(location.getLongitude());
sb.append("nradius : ");
sb.append(location.getRadius());
if (location.getLocType() == BDLocation.TypeGpsLocation) {
sb.append("nspeed : ");
sb.append(location.getSpeed());
sb.append("nsatellite : ");
sb.append(location.getSatelliteNumber());
} else if (location.getLocType() == BDLocation.TypeNetWorkLocation) {
sb.append("naddr : ");
sb.append(location.getAddrStr());
}
String place = location.getAddrStr();
//
locationplace.setText(location.getCity());
localcity.setCity(location.getCity());
Toast.makeText(getApplicationContext(), "" + place, 1).show();
}
}
下面就是如何获取天气:
获取天气的接口,网上有很多,但有的 已经不能再用了,而且调用的时候 很不稳定,数据不够准确;这里是网上找的一个网友搜集的比较全的一个天气api接口:
http://www.eoeandroid.com/thread-333874-1-1.html
这里我用的是:http://weather.51wnl.com/weatherinfo/GetMoreWeather?cityCode=101040100&weatherType=0
感觉还不错,其中cityCode是城市的代号,type 为0的时候 是最近几天的详细天气,为1的时候 是当前温度信息;首先定义一个Weather类:
package com.example.util;
public class Weather {
private String city;
private String cityId;
private String toptemp;
private String lowtemp;
private String weather;
//天气
private String wind;
//风向
private String windfl;
//风力
private String gxtime;
private String index;
//穿衣指数
private String index_d; //穿衣建议
public String getCity() {
return city;
}
public void setCity(String city) {
this.city = city;
}
public String getCityId() {
return cityId;
}
public void setCityId(String cityId) {
this.cityId = cityId;
}
public String getToptemp() {
return toptemp;
}
public void setToptemp(String toptemp) {
this.toptemp = toptemp;
}
public String getLowtemp() {
return lowtemp;
}
public void setLowtemp(String lowtemp) {
this.lowtemp = lowtemp;
}
public String getWeather() {
return weather;
}
public void setWeather(String weather) {
this.weather = weather;
}
public String getGxtime() {
return gxtime;
}
public void setGxtime(String gxtime) {
this.gxtime = gxtime;
}
public String getWind() {
return wind;
}
public void setWind(String wind) {
this.wind = wind;
}
public String getWindfl() {
return windfl;
}
public void setWindfl(String windfl) {
this.windfl = windfl;
}
public String getIndex() {
return index;
}
public void setIndex(String index) {
this.index = index;
}
public String getIndex_d() {
return index_d;
}
public void setIndex_d(String index_d) {
this.index_d = index_d;
}
}
获取天气的方法:
public void GetFirstWeather(){
URL url1, url2;
if (isInterent.hasInternet(this)) {
mLocationClient.requestLocation();
String city = localcity.getCity();
if (city.contains("市") || city.contains("省")) {
City = city.substring(0, city.length() - 1);
}
try {
url1 = new URL(
String.format(getString(R.string.weatherurl)
+ "?cityCode=%1$s&weatherType=0",
LocalCity.getCityIdByName(City)));
GetWeather nt = new GetWeather(url1, "0");
nt.start();
url2 = new URL(
String.format(getString(R.string.weatherurl)
+ "?cityCode=%1$s&weatherType=1",
LocalCity.getCityIdByName(City)));
GetWeather nt1 = new GetWeather(url2, "1");
nt1.start();
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
} else {
Toast.makeText(getApplicationContext(), "网络异常,请检查网络是否连接",
Toast.LENGTH_LONG).show();
}
}
class GetWeather extends Thread {
private URL url;
private String IsNow;
public GetWeather(URL url, String IsNow) {
this.url = url;
this.IsNow = IsNow;
}
@Override
public void run() {
HttpURLConnection conn = null; // 连接对象
String resultData = HttpUtil.getResault(conn, url);
Log.i("天气", resultData);
String resultmsg = null;
Looper.prepare();
if (IsNow.equals("0")) {
Message msg = new Message();
resultmsg = json(resultData);
msg.what = 1;
msg.obj = resultmsg;
handler.sendMessage(msg);
} else {
Message msg1 = new Message();
resultmsg = json1(resultData);
msg1.what = 2;
msg1.obj = resultmsg;
handler.sendMessage(msg1);
}
Looper.loop();
}
}
// 解析天气的json数据
public String json(String json) {
String jsonresult = null;
Weather weather = new Weather();
try {
obj = new JSONObject(json);
JSONObject contentObject = obj.getJSONObject("weatherinfo");
weather.setCity(contentObject.getString("city"));
weather.setToptemp(contentObject.getString("temp1"));
weather.setWeather(contentObject.getString("weather1"));
weather.setIndex(contentObject.getString("index"));
weather.setIndex_d(contentObject.getString("index_d"));
jsonresult = weather.getCity() + ":
" + weather.getToptemp()
+ "n天气:" + weather.getWeather() + "
"
+"n穿衣指数:" + weather.getIndex() + "n" + weather.getIndex_d();
} catch (JSONException e) {
Log.i("Tag", "解析json失败");
e.printStackTrace();
}
weather = null;
return jsonresult;
}
// 解析实时天气的json数据
public String json1(String json) {
String jsonresult = null;
Weather weather = new Weather();
try {
obj = new JSONObject(json);
JSONObject contentObject = obj.getJSONObject("weatherinfo");
weather.setToptemp(contentObject.getString("temp"));
weather.setWind(contentObject.getString("WD"));
weather.setWindfl(contentObject.getString("WS"));
weather.setGxtime(contentObject.getString("time"));
jsonresult = "当前温度:" + weather.getToptemp() + "
风向风力:
"
+ weather.getWind() + weather.getWindfl() + "
"
+ weather.getGxtime() + "发布";
} catch (JSONException e) {
Log.i("Tag", "解析json失败");
e.printStackTrace();
}
weather = null;
return jsonresult;
}
根据定位返回的城市信息,获取城市天气代号代码:
package com.example.util;
public class LocalCity {
public static String cityIds = "北京:101010100朝阳:101010300顺义:101010400" +
