Ⅰ android怎麼獲取實時天氣
准備工作：
1.下載華為能力SDK；http://imax.vmall.com/nj-campus/universityEpDown/toDownPage
2.申請一個應用獲取appId和appkey，待會要用到。
簡單的思路就是先通過網路或者gps獲取到當前位置的經緯度，然後通過sdk查詢溫度，獲取結果。
具體步驟如下：
1.創建工程
把sdk中jar包拖到工程中的libs文件夾下面。
2.主類代碼如下
package com.empty.weatherreport;
import com.empty.weatherreport.WeatherUtil.SCell;
import com.empty.weatherreport.WeatherUtil.SItude;
import com.imax.vmall.sdk.android.common.adapter.ServiceCallback;
import com.imax.vmall.sdk.android.entry.CapabilityService;
import com.imax.vmall.sdk.android.entry.CommonService;
import com.imax.vmall.sdk.android.huawei.weather.WeatherService;
import android.location.Location;
import android.location.LocationManager;
import android.os.Bundle;
import android.os.Handler;
import android.os.Looper;
import android.os.Message;
import android.app.Activity;
import android.app.AlertDialog;
import android.app.ProgressDialog;
import android.content.Context;
import android.util.Log;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.TextView;
import android.widget.Toast;
public class WeatherActivity extends Activity {
private MyHandler myHandler;
private ProgressDialog mProgressDialog;
private Location mLocation;
private boolean sdkStatus;
//Tool to get weather
/**
* CommonService
*/
private CommonService cs;
/**

*/
private WeatherService weather;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_weather);
sdkStatus=false;
myHandler=new MyHandler();
//初始化業務介面實例
weather = CapabilityService.getWeatherServiceInstance();
//實例化CommonService
cs=CommonService.getInstance();
initSDK();
}
private void initSDK()
{
//應用ID，請去iMAX平台注冊申請
String appId="******";
//應用Key
String appKey="******";
//通過CommonService調用鑒權介面，在調用其它能力前必須保證鑒權初始化成功
cs.init(WeatherActivity.this,appId, appKey, new ServiceCallback() {
public void onError(String arg0) {
// TODO Auto-generated method stub
//設置消息
Message msg = new Message();
msg = new Message();
msg.what = 2;
msg.obj = "SDK initialize failed!";
myHandler.sendMessage(msg);
}
public void onComplete(String arg0) {
// TODO Auto-generated method stub
//設置消息
Message msg = new Message();
msg = new Message();
msg.what = 2;
msg.obj = "SDK initialize success!";
sdkStatus=true;
myHandler.sendMessage(msg);
}
});
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.activity_weather, menu);
return true;
}
@Override
public boolean onMenuItemSelected(int featureId, MenuItem item) {
// TODO Auto-generated method stub
if(item.getItemId()==R.id.menu_settings) Toast.makeText(getApplicationContext(), "Ha", Toast.LENGTH_SHORT).show();
if(item.getItemId()==R.id.menu_weather)
{
if(sdkStatus)
{
/** 彈出一個等待狀態的框 */
mProgressDialog = new ProgressDialog(this);
mProgressDialog.setMessage("Waiting...");
mProgressDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);
mProgressDialog.show();
WeatherThread m = new WeatherThread();
new Thread(m).start();
}
else
Toast.makeText(getApplicationContext(), "SDK not installed", Toast.LENGTH_SHORT).show();
}
return super.onMenuItemSelected(featureId, item);
}
/** 顯示結果 */
private void showResult(String s) {
String tmp[]=s.split("\"");
for(int i=0;i<tmp.length;i++)
Log.i("tmp"+i, tmp[i]);
new AlertDialog.Builder(this) .setTitle("Weather") .setMessage("latitude："+mLocation.getLatitude()+"\n longitude："
+mLocation.getLongitude()+"\ntmperature:"+tmp[21]) .show();
}
class MyHandler extends Handler {
public MyHandler() {
}
public MyHandler(Looper L) {
super(L);

// 子類必須重寫此方法,接管數據
@Override

/** 顯示結果 */
switch(msg.what)
{
case 1:
Log.i("Error", "case1");
mProgressDialog.dismiss();
showResult((String)msg.obj);
break;
case 2:
Toast.makeText(getApplicationContext(), (String)msg.obj, Toast.LENGTH_SHORT).show();
break;
default:;
}
super.handleMessage(msg);
// 此處可以更新UI
}
}
class WeatherThread implements Runnable {
public void run() {
final Message msg = new Message();
msg.what=1;
try {
mLocation=getLocation(WeatherActivity.this);
weather.getWeather(Double.toString(mLocation.getLongitude()),Double.toString(mLocation.getLatitude()), new ServiceCallback()
{
public void onError(String arg0)
{
//api介面調用錯誤響應
Log.i("Error", "getWeather error:"+arg0);
//設置消息
msg.obj = arg0;
/** 關閉對話框 */
myHandler.sendMessage(msg); // 向Handler發送消息,更新UI
}
public void onComplete(String arg0)
{
//api介面調用成功響應
Log.i("Complete", "getWeather complete:"+arg0);
//設置消息
msg.obj = arg0;
/** 關閉對話框 */
myHandler.sendMessage(msg); // 向Handler發送消息,更新UI
}
});
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
//Get the Location by GPS or WIFI
public Location getLocation(Context context) {
LocationManager locMan = (LocationManager) context
.getSystemService(Context.LOCATION_SERVICE);
Location location = locMan
.getLastKnownLocation(LocationManager.GPS_PROVIDER);
if (location == null) {
location = locMan
.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
}
return location;
}
}
3.載manifest文件中添加許可權
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" >
</uses-permission>
<uses-permission android:name="android.permission.INTERNET" >
</uses-permission>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" >
</uses-permission>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
