android腾讯网络定位,实现android基于腾讯的定位并判断网络连接

实现android基于腾讯的定位并判断网络连接因为定位需要网络，所以如果不判断网络容易引起程序崩溃所以在定位前需要判断网络连接

本例子的源代码已上传我的资源页

主要步骤：

1.    导入腾讯定位所需jar包

2.    配置androidmanifest.xml权限 并添加腾讯定位的key

3.编写判断网络状态工具类

4.实现判断网络并定位

一，    导入腾讯定位所需jar包

jar 包在我的源代码中有

二，    配置androidmanifest.xml权限 并添加腾讯定位的key

androidmanifest.xml权限：

腾讯定位的key 需要添加在之后之前

android:name="TencentMapSDK"

android:value="DUSBZ-LL63F-FOIJI-J2GW4-TWNFT-FEFBB"/>

三，    编写判断网络状态工具类

import android.app.Activity;

import android.content.Context;

import android.net.ConnectivityManager;

import android.net.NetworkInfo;

public classPanduanNet {

/**

* 2015.5.18判断网络yang

*

*/

public static boolean detect(Activity act) {

ConnectivityManagermanager = (ConnectivityManager) act

.getApplicationContext().getSystemService(

Context.CONNECTIVITY_SERVICE);

if (manager == null) {

return false;

}

NetworkInfonetworkinfo = manager.getActiveNetworkInfo();

if (networkinfo == null ||!networkinfo.isAvailable()) {

return false;

}

return true;

}

}

四，    实现判断网络并定位

public classMainActivity extends Activity implements TencentLocationListener {

private TextView locationtext;

private TencentLocationManager locationManager;

private TencentLocationRequest request;

@Override

protectedvoidonCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

locationtext=(TextView)findViewById(R.id.location);

boolean networkState=PanduanNet.detect(MainActivity.this);

if(!networkState)//判断网络

{

Toast.makeText(this, "定位失败，请连接网络", Toast.LENGTH_SHORT).show();

}else{

locationManager =TencentLocationManager.getInstance(this);

locationManager          .setCoordinateType(TencentLocationManager.COORDINATE_TYPE_GCJ02);

request = TencentLocationRequest.create();

request.setInterval(3000);

request.setRequestLevel(TencentLocationRequest.REQUEST_LEVEL_ADMIN_AREA);

int error = locationManager.requestLocationUpdates(request, this);

if (error == 0) {

System.out.println("地址获取成功");

}

}

}

@Override

public voidonLocationChanged(TencentLocation location, int error, String reason) {

//TODOAuto-generated method stub

//定位成功，获取城市，街区地址

if (error ==TencentLocation.ERROR_OK) {

Log.d("location",""+ location);

Stringaddress = location.getCity().toString()

+location.getTown().toString();

if(location.getStreet().toString().equals("Unknown")) {

//未得到街道地址

locationtext.setText(address);

}else{

//得到街道地址

locationtext.setText(address+ location.getStreet().toString());

}

Toast.makeText(MainActivity.this, "当前位置为" + address + "！！返回可以重新定位",

Toast.LENGTH_SHORT).show();

//停止定位

stopLocation();

}else{

//停止定位

stopLocation();

//定位失败

Toast.makeText(this, "定位失败，请连接网络", Toast.LENGTH_SHORT)

.show();

}

}

@Override

public void onStatusUpdate(Stringarg0, intarg1, String arg2) {

}

public void stopLocation() {

locationManager.removeUpdates(this);

}

}
