Android联网方式判断详解

工作闲余时间学习了下其它项目中的联网方式判断，很简单的..今天有时间就放博客里面供自己记录，有需要的朋友可以同小马交流交流，希望大家多多指点。。谢谢。。

主类：

package com.xiaoma.www;

import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.database.Cursor;
import android.net.ConnectivityManager;
import android.net.NetworkInfo;
import android.net.NetworkInfo.State;
import android.net.Uri;
import android.os.Bundle;
import android.widget.TextView;

/**

*/
public class JudgeNewWayDemoActivity extends Activity {

private TextView text;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);

/**
* 下面列举几个可直接跳到联网设置的意图,供大家学习
*/
//startActivity(new Intent(android.provider.Settings.ACTION_APN_SETTINGS));
//startActivity(new Intent(android.provider.Settings.ACTION_SETTINGS));

//用下面两种方式设置网络
//startActivity(new Intent(android.provider.Settings.ACTION_WIFI_SETTINGS));
//startActivity(new Intent(android.provider.Settings.ACTION_WIRELESS_SETTINGS));
init();
}

/**
* 初始化实现
*/
private void init(){
text = (TextView)findViewById(R.id.waytext);
/**获得系统级联网管理员对象*/
ConnectivityManager manager = (ConnectivityManager)this.getSystemService(CONNECTIVITY_SERVICE);
NetworkInfo info = manager.getActiveNetworkInfo();
if(info == null){  //无网情况下
//跳转到网络设置页面
startActivity(new Intent(android.provider.Settings.ACTION_SETTINGS));
}else{   //有网情况下
if(info.isAvailable()){ //网络可用时
/**是手机自带的联网方式*/
if(info.getType() == ConnectivityManager.TYPE_MOBILE){
if(info.getState() == State.CONNECTED){
text.setText(String.valueOf("手机网络可用并已连接"+"\n"+"连接网络方式为:\n"+info.getType()+",MOBILE"));
}

/**WIFI联网方式*/
}else{
text.setText(String.valueOf("连接网络方式为:"+info.getType()+",WI-FI"));
startActivity(new Intent(android.provider.Settings.ACTION_WIFI_SETTINGS));
}
}else{
text.setText(String.valueOf("手机网络不可用"));
}

}
}

/**
* 临时写来练练的方法,大家可以跳过
*/
private void kkk(){
Uri uri = Uri.parse("content://telephony/carriers");
Cursor cr = getContentResolver().query(uri, null, null, null, null);
while(cr!=null && cr.moveToNext()){
// APN id
String id = cr.getString(cr.getColumnIndex("_id"));
// APN name
String apn = cr.getString(cr.getColumnIndex("apn"));
// do other things...
}
}

/**
* 移动或联通ctwap cmwap 判断  这个方法朋友们可根据自己的需要使用,小马
* 只是记在这个地方,供自己记录的,有需要的朋友可以交流讨论下..吼吼
*/
@SuppressWarnings("unused")
private void initWapState() {
//ConnectivityManager: Class that answers queries about the state of network connectivity.
ConnectivityManager conMan = (ConnectivityManager)
getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo netInfo = conMan.getActiveNetworkInfo();
if (netInfo != null) {
String extraInfo = netInfo.getExtraInfo();//Report the extra information about the network state
if (extraInfo != null) {
if (extraInfo.equals("cmwap")) {

}else if(extraInfo.equals("ctwap") || extraInfo.equals("#777")){

}
}
}
}

}
