- 获取当前网络类型
- 检测网络是否可用
- 通过广播监听网络状态
1. 获取当前网络类型
/**
* 获取当前网络类型
*
* @return 0：没有网络 1：WIFI网络 2：WAP网络 3：NET网络
*/
public static int getNetworkType(Context context) {
int netType = 0;
ConnectivityManager connectivityManager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo networkInfo = connectivityManager.getActiveNetworkInfo();
if (networkInfo == null) {
return netType;
}
int nType = networkInfo.getType();
if (nType == ConnectivityManager.TYPE_MOBILE) {
String extraInfo = networkInfo.getExtraInfo();
if (!TextUtils.isEmpty(extraInfo)) {
if (extraInfo.toLowerCase(Locale.getDefault()).equals("cmnet")) {
netType = NETTYPE_CMNET;
} else {
netType = NETTYPE_CMWAP;
}
}
} else if (nType == ConnectivityManager.TYPE_WIFI) {
netType = NETTYPE_WIFI;
}
return netType;
}
2. 检测网络是否可用
/**
* 检测网络是否可用
*
* @return
*/
public static boolean isNetworkConnected(Context context) {
ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo ni = cm.getActiveNetworkInfo();
return ni != null && ni.isConnectedOrConnecting();
}
3. 通过广播监听网络状态
静态注册
<!--监听网络状态变化的广播-->
<receiver android:name=".controller.service.NetBroadcastReceiver">
<intent-filter>
<action android:name="android.net.conn.CONNECTIVITY_CHANGE" />
<action android:name="android.net.wifi.WIFI_STATE_CHANGED" />
<action android:name="android.net.wifi.STATE_CHANGE" />
</intent-filter>
</receiver>
/**
* 自定义检查手机网络状态是否切换的广播接受器
*/
public class NetBroadcastReceiver extends BroadcastReceiver {
public NetEvevt evevt = BaseActivity.evevt;
@Override
public void onReceive(Context context, Intent intent) {
// 如果相等的话就说明网络状态发生了变化
if (intent.getAction().equals(ConnectivityManager.CONNECTIVITY_ACTION)) {
int netWorkState = NetUtils.getNetWorkState(context);
// 接口回调传过去状态的类型
evevt.onNetChange(netWorkState);
}
}
// 自定义接口
public interface NetEvevt {
void onNetChange(int netMobile);
}
}
/**
* 网络类型
*/
private int netMobile;
public static NetBroadcastReceiver.NetEvevt evevt;
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//监听网络变化
evevt = this;
inspectNet();
}
/**
* 网络变化之后的类型
*/
@Override
public void onNetChange(int netMobile) {
this.netMobile = netMobile;
if (isNetConnect()) {
tv_netstates.setVisibility(View.GONE);
} else {
tv_netstates.setVisibility(View.VISIBLE);
}
}
/**
* 判断有无网络 。
*
* @return true 有网, false 没有网络.
*/
public boolean isNetConnect() {
// public static final int NETTYPE_WIFI = 0;
// public static final int NETTYPE_NONE = 1;
// public static final int NETTYPE_2G = 2;
// public static final int NETTYPE_3G = 3;
// public static final int NETTYPE_4G = 4;

return false;
} else {
return true;
