現附上一段代碼，這段代碼參考了很多人的并且進行了自己的補充和注釋 ~~~ public class MainActivity extends Activity { private TextView netWork; private TextView wifi; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); netWork=(TextView)this.findViewById(R.id.netWorkAvaliable); wifi=(TextView)this.findViewById(R.id.wifiAvaliable); testConnectivityManager(); } public void testConnectivityManager() { Context context = this.getApplicationContext();//獲取應用上下文 // ConnectivityManager connectivityManager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);//獲取系統的連接服務 //NetworkInfo activeNetInfo = connectivityManager.getActiveNetworkInfo();//獲取網絡的連接情況 WifiManager wifiManager = (WifiManager) this.getSystemService(Context.WIFI_SERVICE); if (wifiManager.isWifiEnabled()==true) { wifi.setText("wifi closing"); toggleWiFi(false); } stratWifiAp(wifiManager); //if(activeNetInfo.getType()==ConnectivityManager.TYPE_WIFI){ //判斷WIFI網 // wifi.setText("wifi setting"); // toggleWiFi(false); // } } public void toggleWiFi(boolean status) { WifiManager wifiManager = (WifiManager) this .getSystemService(Context.WIFI_SERVICE); if (status == true && !wifiManager.isWifiEnabled()) { wifiManager.setWifiEnabled(true); } else if (status == false && wifiManager.isWifiEnabled()) { wifiManager.setWifiEnabled(false); } } public void stratWifiAp(WifiManager wifiManager) { Method method1 = null; try { method1 = wifiManager.getClass().getMethod("setWifiApEnabled", WifiConfiguration.class, boolean.class); WifiConfiguration netConfig = new WifiConfiguration(); //wifi熱點名字 netConfig.SSID = "Hehyu"; netConfig.allowedAuthAlgorithms .set(WifiConfiguration.AuthAlgorithm.OPEN); netConfig.allowedProtocols.set(WifiConfiguration.Protocol.RSN); netConfig.allowedProtocols.set(WifiConfiguration.Protocol.WPA); netConfig.allowedKeyManagement .set(WifiConfiguration.KeyMgmt.WPA_PSK); netConfig.allowedPairwiseCiphers .set(WifiConfiguration.PairwiseCipher.CCMP); netConfig.allowedPairwiseCiphers .set(WifiConfiguration.PairwiseCipher.TKIP); netConfig.allowedGroupCiphers .set(WifiConfiguration.GroupCipher.CCMP); netConfig.allowedGroupCiphers .set(WifiConfiguration.GroupCipher.TKIP); //密碼 netConfig.preSharedKey = "19921214"; method1.invoke(wifiManager, netConfig, true); } catch (IllegalArgumentException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IllegalAccessException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (InvocationTargetException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (SecurityException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (NoSuchMethodException e) { // TODO Auto-generated catch block e.printStackTrace(); } } } ~~~ 因為時間比較晚了，明天再進行代碼的補充和注釋吧
