本文介绍了一个结合定位功能的天气查询应用程序实现方案，包括通过百度地图API获取用户当前位置，并利用HTTP请求查询并展示不同城市的天气预报。该应用还设计了导航抽屉以方便选择不同的城市进行天气查询。

2 定位当前位置并查询天气或者查询列表以及其他城市的天气

1） HttpCallbackListener定义一个接口

package com.example.d99;

public interface HttpCallbackListener
{
	void onFinish(String response);
	void onError(Exception e);
}

2）HttpUtil 建一个子线程

package com.example.d99;

import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;

public class HttpUtil
{

	public static void sendHttpRequest(final String address, final HttpCallbackListener listener)
	{
		new Thread(new Runnable()
		{
			@Override
			public void run()
			{
				HttpURLConnection connection = null;
				try
				{
					URL url = new URL(address);
					connection = (HttpURLConnection) url.openConnection();
					connection.setRequestMethod("GET");
					connection.setConnectTimeout(8000);
					connection.setReadTimeout(8000);
					connection.setDoInput(true);
					connection.setDoOutput(true);
					InputStream in = connection.getInputStream();
					BufferedReader reader = new BufferedReader(new InputStreamReader(in));
					StringBuilder response = new StringBuilder();
					String line;
					while ((line = reader.readLine()) != null)
					{
						response.append(line);
					}
					if (listener != null)
					{
						// 回调onFinish()方法
						listener.onFinish(response.toString());
					}
				} catch (Exception e)
				{
					if (listener != null)
					{
						// 回调onError()方法
						listener.onError(e);
					}
				} finally
				{
					if (connection != null)
					{
						connection.disconnect();
					}
				}
			}
		}).start();
	}
}

3）WeatherAdapter建一个适配器

package com.example.d99;

import java.util.List;

import com.example.d99.R;

import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.TextView;



public class WeatherAdapter extends ArrayAdapter<Weather>
{
	private int resourceId;

	public WeatherAdapter(Context context, int textViewResourceId, List<Weather> objects)
	{
		super(context, textViewResourceId, objects);
		resourceId = textViewResourceId;
	}

	@Override
	public View getView(int position, View convertView, ViewGroup viewgroup)
	{
		Weather weather = getItem(position);
		ViewHolder viewHolder = null;
		if (convertView == null)
		{
			viewHolder = new ViewHolder();
			convertView = LayoutInflater.from(getContext()).inflate(resourceId, null);
			viewHolder.tvDayOfWeek = (TextView) convertView.findViewById(R.id.tvDayofWeek);
			viewHolder.tvDate = (TextView) convertView.findViewById(R.id.tvDate);
			viewHolder.tvTemperature = (TextView) convertView.findViewById(R.id.tvTemperature);
			viewHolder.tvWeather = (TextView) convertView.findViewById(R.id.tvWeather);
			convertView.setTag(viewHolder);
		} else
		{
			viewHolder = (ViewHolder) convertView.getTag();
		}
		viewHolder.tvDayOfWeek.setText(weather.getDayOfWeek());
		viewHolder.tvDate.setText(weather.getDate());
		viewHolder.tvTemperature.setText(weather.getTemperature());
		viewHolder.tvWeather.setText(weather.getWeather());
		return convertView;
	}

	private class ViewHolder
	{
		TextView tvDayOfWeek;
		TextView tvDate;
		TextView tvTemperature;
		TextView tvWeather;
	}
}

4）Weather.java

package com.example.d99;

public class Weather
{
	private String dayOfWeek;// 星期几
	private String date;// 日期
	private String temperature;// 温度
	private String weather;// 天气

	public Weather()
	{
	}
	public Weather(String dayOfWeek, String date, String temperature, String weather)
	{

		super();
		this.dayOfWeek = dayOfWeek;
		this.date = date;
		this.temperature = temperature;
		this.weather = weather;
	}

	public String getDayOfWeek()
	{
		return dayOfWeek;
	}

	public void setDayOfWeek(String dayOfWeek)
	{
		this.dayOfWeek = dayOfWeek;
	}

	public String getDate()
	{
		return date;
	}

	public void setDate(String date)
	{
		this.date = date;
	}

	public String getTemperature()
	{
		return temperature;
	}

	public void setTemperature(String temperature)
	{
		this.temperature = temperature;
	}

	public String getWeather()
	{
		return weather;
	}

	public void setWeather(String weather)
	{
		this.weather = weather;
	}

	@Override
	public String toString()
	{
		return "Weather [dayOfWeek=" + dayOfWeek + ", date=" + date + ", temperature=" + temperature + ", weather="
				+ weather + "]";
	}
}

5）MianActivity.javaa主函数：
