任何會檢查Android手機中是否有互聯網連接的功能？

我想做一個功能，將檢查互聯網是在Android手機上。請幫助..任何會檢查Android手機中是否有互聯網連接的功能？

也看看這個，看看你是通過WiFi /移動連接：http://stackoverflow.com/a/6357668/198348 - 雖然這保證了網絡連接已經結束，而不是互聯網本身已經啓動。 – 2012-08-17 15:42:07

這將返回圖像的位圖

private Bitmap download_Image(String url) { 
     Bitmap bm = null; 
     try { 
      URL aURL = new URL(url); 
      URLConnection conn = aURL.openConnection(); 
      conn.connect(); 
      InputStream is = conn.getInputStream(); 
      BufferedInputStream bis = new BufferedInputStream(is); 
      bm = BitmapFactory.decodeStream(bis); 
      bis.close(); 
      is.close(); 
     } catch (IOException e) { 

     } 
     return bm; 
    }

集位圖來ImageView的

imageView.setImageBitmap(result);

private boolean haveInternet() { 
     NetworkInfo info = ((ConnectivityManager) getSystemService(Activity.CONNECTIVITY_SERVICE)) 
       .getActiveNetworkInfo(); 
     if (info == null || !info.isConnected()) { 
      return false; 
     } 
     return true; 
    }

希望這有助於！

這將幫助你..

private boolean netCheckin() { 

    try { 

     ConnectivityManager nInfo = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE); 
     nInfo.getActiveNetworkInfo().isConnectedOrConnecting(); 

     Log.d(tag, "Net avail:" 
       + nInfo.getActiveNetworkInfo().isConnectedOrConnecting()); 

     ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE); 
     NetworkInfo netInfo = cm.getActiveNetworkInfo(); 
     if (netInfo != null && netInfo.isConnectedOrConnecting()) { 
      Log.d(tag, "Network available:true"); 
      return true; 
     } else { 
      Log.d(tag, "Network available:false"); 
      return false; 
     } 

    } catch (Exception e) { 
     return false; 
    } 
}

使用此：

public boolean IsNetConnected() 
{ 
    boolean NetConnected = false; 
    try 
    { 
     ConnectivityManager connectivity = (ConnectivityManager)ClassContext.getSystemService(Context.CONNECTIVITY_SERVICE); 
      if (connectivity == null) 
      { 
       Log.w("tag", "couldn't get connectivity manager"); 
       NetConnected = false; 
      } 
      else 
      { 
      NetworkInfo[] info = connectivity.getAllNetworkInfo(); 
      if (info != null) 
      { 
       for (int i = 0; i < info.length; i++) 
       { 
        if (info[i].getState() == NetworkInfo.State.CONNECTED) 
        { 
         NetConnected = true; 
        } 
       } 
      } 
     } 
    } 
    catch (Exception e) { 
     // TODO: handle exception 
     NetConnected = false; 
    } 
    return NetConnected;   
}

請結算功能...

public boolean checkNetworkRechability() { 
     Boolean bNetwork = false; 
     ConnectivityManager connectivityManager = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE); 

     for (NetworkInfo networkInfo : connectivityManager.getAllNetworkInfo()) { 
      int netType = networkInfo.getType(); 
      int netSubType = networkInfo.getSubtype(); 

      if (netType == ConnectivityManager.TYPE_WIFI) { 
       bNetwork = networkInfo.isConnected(); 
       if (bNetwork == true) 
        break; 
      } else if (netType == ConnectivityManager.TYPE_MOBILE 
        && netSubType != TelephonyManager.NETWORK_TYPE_UNKNOWN) { 
       bNetwork = networkInfo.isConnected(); 
       if (bNetwork == true) 
        break; 
      } else { 
       bNetwork = false; 
      } 
     } 
     if (!bNetwork) { 
      Toast.makeText(getApplicationContext(),"You are not in network",Toast.LENGTH_SHORT).show(); 
     } 
     return bNetwork; 
    }
