百度定位VS高德定位

高德  下载

添加 AMap_Location  jar包，在AndroidManifest 添加权限，并在 application下 添加申请到的 key

这里还可以添加service，不过我发现不添加也没有影响

<service android:name="com.amap.api.location.APSService"></service>

之后就可以使用定位了，定位得到的 AMapLocation 对象 直接tostring就能得到所有的定位信息。

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.TextView;

import com.amap.api.location.AMapLocation;
import com.amap.api.location.AMapLocationClient;
import com.amap.api.location.AMapLocationListener;

public class LocationActivity extends AppCompatActivity {

    private TextView tv;
    public AMapLocationClient LocationClient = null;
    public AMapLocationListener LocationListener = new AMapLocationListener() {
        @Override
        public void onLocationChanged(AMapLocation aMapLocation) {
            if (aMapLocation != null) {
                if (aMapLocation.getErrorCode() == 0) {
                    tv.setText(aMapLocation.toString());
                }
            }
        }
    };

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_location);
        tv = (TextView) findViewById(R.id.tv);
        LocationClient = new AMapLocationClient(getApplicationContext());
        LocationClient.setLocationListener(LocationListener);
    }

    public void btn(View view) {
        switch (view.getId()) {
            case R.id.btn1:
                LocationClient.startLocation();
                break;

            case R.id.btn2:
                LocationClient.stopLocation();
                break;
        }
    }
}

百度  下载

百度定位的sdk 除了jar包还有so库，所以添加的东西要比高德多。

在AndroidManifest 添加权限，并在 application下 添加申请到的 key，而百度这里必须添加service

<service android:name="com.baidu.location.f" android:enabled="true" android:process=":remote"> </service>

之后就可以定位了

这里比高德稍微麻烦一点，还要配置定位SDK参数 LocationClientOption，不然最多只能拿到经纬度，而获取不到具体信息

而且获取到的 BDLocation 对象，不能tostring，只能按需求取数据

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.TextView;

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

public class BaiduActivity extends AppCompatActivity {

    private TextView tv;
    private LocationClient locationClient = null;
    private BDLocationListener bdLocationListener = new BDLocationListener() {
        @Override
        public void onReceiveLocation(BDLocation bdLocation) {
            if (null != bdLocation && bdLocation.getLocType() != BDLocation.TypeServerError) {
                tv.setText(bdLocation.getLocType() + bdLocation.getAddrStr() + " " + bdLocation.getBuildingName()
                        + " " + bdLocation.getDistrict() + " " + bdLocation.getFloor() + " " + bdLocation.getStreet()
                        + " " + bdLocation.getTime()
                );
            }
        }
    };

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_baidu);

        tv = (TextView) findViewById(R.id.tv);

        locationClient = new LocationClient(getApplicationContext());
        locationClient.registerLocationListener(bdLocationListener);

        LocationClientOption clientOption = new LocationClientOption();
        clientOption.setLocationMode(LocationClientOption.LocationMode.Hight_Accuracy);
        clientOption.setCoorType("bd09ll");
        clientOption.setIsNeedAddress(true);
        clientOption.setIsNeedLocationDescribe(true);
        clientOption.setIsNeedLocationPoiList(true);

        locationClient.setLocOption(clientOption);
    }

    public void btn(View view) {
        switch (view.getId()) {
            case R.id.btn1:
                locationClient.start();
                break;

            case R.id.btn2:
                locationClient.stop();
                break;
        }
    }
}

简单对比

值得一提的是 高德在直接LocationClient.stopLocation() 时，会明显卡顿，说明阻塞了主线程，还是开新线程关闭好

获取key的方法

打开cmd，定位到.android文件夹下，输入cd .android

keytool -list -v -keystore C:\AndroidProject\demonkey.jks

然后输入密码  复制sha1就行了
