Android判断GPS、wifi、移动网络是否可用的探知函数

编写GPS代码的时候总是要做这个判断，干脆封装成一个函数，随用随取。

public boolean isGpsEnabled(Context context)

{

LocationManager locationManager =

((LocationManager)context.getSystemService(Context.LOCATION_SERVICE));

List<String> accessibleProviders = locationManager.getProviders(true);

return accessibleProviders != null && accessibleProviders.size() > 0;

}
判断GPS是否可用:

LocationManager lm =(LocationManager)this.getSystemService(Context.LOCATION_SERVICE);
boolean GPS_status = lm.isProviderEnabled(LocationManager.GPS_PROVIDER);
boolean NETWORK_status = lm.isProviderEnabled(LocationManager.NETWORK_PROVIDER);

类似的wifi是否打开

public boolean isWifiEnabled(Context context)

{

ConnectivityManager mgrConn = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE); 

TelephonyManager mgrTel = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE); 

return ((mgrConn.getActiveNetworkInfo()!=null && mgrConn.getActiveNetworkInfo().getState()==NetworkInfo.State.CONNECTED) 

|| mgrTel.getNetworkType() == TelephonyManager.NETWORK_TYPE_UMTS) 

}

网络连接是否好用

public static boolean isNetworkConnected(Context context){  

  ConnectivityManager cm = (ConnectivityManager)context.getSystemService(Context.CONNECTIVITY_SERVICE);  

  NetworkInfo network = cm.getActiveNetworkInfo();  

  if(network != null){  

  return network.isAvailable();  

  }  

  return false;  
} 

android中判断网络连接是否可用

一、判断网络连接是否可用

 

public static boolean isNetworkAvailable(Context context) {
ConnectivityManager cm = (ConnectivityManager) context
.getSystemService(Context.CONNECTIVITY_SERVICE);
if (cm == null) {
} else {
　　　　　　　//如果仅仅是用来判断网络连接
　　　　　　  //则可以使用 cm.getActiveNetworkInfo().isAvailable();
NetworkInfo[] info = cm.getAllNetworkInfo();
if (info != null) {
for (int i = 0; i < info.length; i++) {
if (info[i].getState() == NetworkInfo.State.CONNECTED) {
return true;
}
}
}
}
return false;
}

  

二、判断GPS是否打开

public static boolean isGpsEnabled(Context context) {
LocationManager lm = ((LocationManager) context
.getSystemService(Context.LOCATION_SERVICE));
List<String> accessibleProviders = lm.getProviders(true);
return accessibleProviders != null && accessibleProviders.size() > 0;
}

三、判断WIFI是否打开

 

public static boolean isWifiEnabled(Context context) {
ConnectivityManager mgrConn = (ConnectivityManager) context
.getSystemService(Context.CONNECTIVITY_SERVICE);
TelephonyManager mgrTel = (TelephonyManager) context
.getSystemService(Context.TELEPHONY_SERVICE);
return ((mgrConn.getActiveNetworkInfo() != null && mgrConn
.getActiveNetworkInfo().getState() == NetworkInfo.State.CONNECTED) || mgrTel
.getNetworkType() == TelephonyManager.NETWORK_TYPE_UMTS);
}

四、判断是否是3G网络

 

public static boolean is3rd(Context context) {
ConnectivityManager cm = (ConnectivityManager) context
.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo networkINfo = cm.getActiveNetworkInfo();
if (networkINfo != null
&& networkINfo.getType() == ConnectivityManager.TYPE_MOBILE) {
return true;
}
return false;
}

五、判断是wifi还是3g网络,用户的体现性在这里了，wifi就可以建议下载或者在线播放。

public static boolean isWifi(Context context) {
ConnectivityManager cm = (ConnectivityManager) context
.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo networkINfo = cm.getActiveNetworkInfo();
if (networkINfo != null
&& networkINfo.getType() == ConnectivityManager.TYPE_WIFI) {
return true;
}
return false;
}
