自己写的定位的小DEMO

废话不说先上图

这是一个简单的定位自己当前的位置的demo，所得的位置是通过调用百度的sdk得到的，代码如下：

首先是布局文件activity_main.xml：

MainActivity.java

package com.author_jsc.libtestDemo;

import com.baidu.location.LocationClient;
import com.baidu.location.LocationClientOption;
import com.baidu.location.LocationClientOption.LocationMode;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.TextView;


public class MainActivity extends Activity {
	
	private Button LocationBtn;
	private TextView LocationText;

	
	private LocationClient mLocationClient;
	private LocationMode tempMode = LocationMode.Hight_Accuracy;
	private String tempcoor="gcj02";
	
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        LocationBtn =(Button) findViewById(R.id.location_btn);
        LocationText = (TextView) findViewById(R.id.location_text);

        ((LocationApplication)getApplication()).mLocationResult = LocationText;
        mLocationClient = ((LocationApplication)getApplication()).mLocationClient;
        
        LocationBtn.setOnClickListener(new OnClickListener() {
			
			@Override
			public void onClick(View v) {
				InitLocation();
				if(LocationBtn.getText().equals(getString(R.string.startlocation))){
					mLocationClient.start();
					LocationBtn.setText(getString(R.string.stoplocation));
				}else{
					mLocationClient.stop();
					LocationBtn.setText(getString(R.string.startlocation));
				}
			}
		});
    }

	@Override
	protected void onStop() {
		mLocationClient.stop();
		super.onStop();
	}

	private void InitLocation(){
		LocationClientOption option = new LocationClientOption();
		option.setLocationMode(tempMode);//设置定位模式
		option.setCoorType(tempcoor);//返回的定位结果是百度经纬度，默认值gcj02
		int span=1000;
		option.setScanSpan(span);//设置发起定位请求的间隔时间为5000ms
		option.setIsNeedAddress(true);
		mLocationClient.setLocOption(option);
	}
}

LocationApplication.java：

package com.author_jsc.libtestDemo;

import android.app.Application;

import com.baidu.location.BDLocation;
import com.baidu.location.BDLocationListener;
import com.baidu.location.GeofenceClient;
import com.baidu.location.LocationClient;

import android.app.Service;
import android.os.Vibrator;
import android.util.Log;
import android.widget.TextView;

public class LocationApplication extends Application {
	public LocationClient mLocationClient;
	public GeofenceClient mGeofenceClient;
	public MyLocationListener mMyLocationListener;
	
	public TextView mLocationResult,logMsg;
	public TextView trigger,exit;
	public Vibrator mVibrator;
	
	@Override
	public void onCreate() {
		super.onCreate();
		mLocationClient = new LocationClient(this.getApplicationContext());
		mMyLocationListener = new MyLocationListener();
		mLocationClient.registerLocationListener(mMyLocationListener);
		mGeofenceClient = new GeofenceClient(getApplicationContext());
		
		
		mVibrator =(Vibrator)getApplicationContext().getSystemService(Service.VIBRATOR_SERVICE);
	}

	
	/**
	 * 实现实位回调监听
	 */
	public class MyLocationListener implements BDLocationListener {

		@Override
		public void onReceiveLocation(BDLocation location) {
			//Receive Location 
			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());
				sb.append("\ndirection : ");
				sb.append("\naddr : ");
				sb.append(location.getAddrStr());
				sb.append(location.getDirection());
			} else if (location.getLocType() == BDLocation.TypeNetWorkLocation){
				sb.append("\naddr : ");
				sb.append(location.getAddrStr());
				//运营商信息
				sb.append("\noperationers : ");
				sb.append(location.getOperators());
			}
			logMsg(sb.toString());
			Log.i("BaiduLocationApiDem", sb.toString());
		}


	}
	
	
	/**
	 * 显示请求字符串
	 * @param str
	 */
	public void logMsg(String str) {
		try {
			if (mLocationResult != null)
				mLocationResult.setText(str);
		} catch (Exception e) {
			e.printStackTrace();
		}
	}
