1.下载华为能力SDK；

2.申请一个应用获取appId和appkey，待会要用到。

简单的思路就是先通过网络或者gps获取到当前位置的经纬度，然后通过sdk查询温度，获取结果。

具体步骤如下：

1.创建工程

把sdk中jar包拖到工程中的libs文件夹下面。

2.主类代码如下

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;

/**

* WeatherService

private WeatherService weather;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_weather);

sdkStatus=false;

myHandler=new MyHandler();

//初始化业务接口实例

weather = CapabilityService.getWeatherServiceInstance();

//实例化CommonService

cs=CommonService.getInstance();

initSDK();

}

private void initSDK()

{

//应用ID，请去iMAX平台注册申请

String appId="******";

//应用Key

String appKey="******";

//通过CommonService调用鉴权接口，在调用其它能力前必须保证鉴权初始化成功

cs.init(WeatherActivity.this,appId, appKey, new ServiceCallback() {

public void onError(String arg0) {

// TODO Auto-generated method stub

//设置消息

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

//设置消息

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)

{

/** 弹出一个等待状态的框 */

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);

}

/** 显示结果 */

private void showResult(String s) {

String tmp[]=s.split("\"");

for(int i=0;itmp.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);

}

// 子类必须重写此方法,接管数据

@Override

public void handleMessage(Message msg) {

// TODO Auto-generated method stub

Log.d("MyHandler", "handleMessage......");

/** 显示结果 */

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);

// 此处可以更新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接口调用错误响应

Log.i("Error", "getWeather error:"+arg0);

//设置消息

msg.obj = arg0;

/** 关闭对话框 */

myHandler.sendMessage(msg); // 向Handler发送消息,更新UI

}

public void onComplete(String arg0)

{

//api接口调用成功响应

Log.i("Complete", "getWeather complete:"+arg0);

//设置消息

msg.obj = arg0;

/** 关闭对话框 */

myHandler.sendMessage(msg); // 向Handler发送消息,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.载manifest文件中添加权限

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" /

android开发怎么显示天气

本经验将介绍Android如何获取天气预报主要使用了中国天气网的接口，使用webView显示。

工具/原料

Android Studio

方法/步骤

首先我们打开下载安装好的Android Studio然后新建一个项目，我这里为了方便就直接添加一个Activity了

然后我们添加界面布局代码，布局如下：

?xml version="1.0" encoding="utf-8"?

LinearLayout xmlns:android=""

android:orientation="vertical"

android:gravity="center_horizontal"

android:layout_width="fill_parent"

android:layout_height="fill_parent"

LinearLayout

android:orientation="horizontal"
