如何编程android来寻找特定的网络？ （问题简单的教程）

本文介绍了如何编程android来寻找特定的网络？ （问题简单的教程）的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 我试图使用以下示例： 如何编程android来寻找特定的网络？ 但是由于以下问题，我无法执行：But I'm unable to execute it due to issues stemming from the line: WifiManager wifiManager =（WifiManager）context.getSystemService（Context.WIFI_SERVICE）; WifiManager wifiManager = (WifiManager)context.getSystemService(Context.WIFI_SERVICE);之后，我收到了其他几个错误 - 但是我认为我正好遵循了这个教程/例子。 After that I'm getting several other errors - but [I think] I've followed the tutorial/example precisely. import java.util.List;import android.app.Activity; import android.net.wifi.WifiConfiguration;import android.net.wifi.WifiManager;import android.os.Bundle;import android.util.Log;import android.content.Context; public class Connect extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.connect); String networkSSID = "ANDRE-PC_NETWORK"; String networkPass = "superman"; WifiConfiguration conf = new WifiConfiguration(); conf.SSID = "\"" + networkSSID + "\""; //ssid must be in quotes conf.wepKeys[0] = "\"" + networkPass + "\""; conf.wepTxKeyIndex = 0; conf.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE); conf.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.WEP40); conf.preSharedKey = "\""+ networkPass +"\""; conf.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE); WifiManager wifiManager = (WifiManager)getSystemService(WIFI_SERVICE); wifiManager.addNetwork(conf); List<WifiConfiguration> list = wifiManager.getConfiguredNetworks(); for( WifiConfiguration i : list ) { if(i.SSID != null && i.SSID.equals("\"" + networkSSID + "\"")) { WifiManager.disconnect(); WifiManager.enableNetwork(i.networkId, true); WifiManager.reconnect(); break; } } }} IN ECLIPSE问题日志：ISSUES IN ECLIPSE PROBLEM LOG:Description Resource Path Location TypeCannot make a static reference to the non-static method reconnect() from the type WifiManager Connect.java line 41 Java ProblemCannot make a static reference to the non-static method disconnect() from the type WifiManager Connect.java line 39 Java ProblemCannot make a static reference to the non-static method enableNetwork(int, boolean) from the type WifiManager Connect.java line 40 Java Problem 推荐答案你似乎混淆了一些变量名：You seem to confuse some variable names:WifiManager wifiManager = (WifiManager)context.getSystemService(Context.WIFI_SERVICE); wifiManager.add(conf);List<WifiConfiguration> list = wifiManager.getConfiguredNetworks();for( WifiConfiguration i : list ) { if(i.SSID != null && i.SSID.equals("\"" + networkSSID + "\"")) { wm.disconnect(); wm.enableNetwork(i.networkId, true); wm.reconnect(); break; } } wifiManager 应该是 wm ，反之亦然。另外上下文应该是这个或者只是作为 getSystemService（）是你的课程的一种方法。wifiManager should be wm or vice versa. Also context should be this or just left out as getSystemService() is a method of your class.我不确定 add（）的问题。 修改：嗯 add（） 不存在 WifiManager 但 addNetwork（），所以我想你需要方法而不是 add（） Well add() does not exist for WifiManager but addNetwork() does, so I guess you need that method instead of add() Edit2 ：你不知道你在做什么，对吧？您甚至不了解类名和变量名之间的区别！You have no idea what you are doing, right? You don't even understand the difference between a class name and a variable name! WifiManager wifiManager 循环中，您使用类型/类而不是变量，因此只需写入 wifiManager 而不是 WifiManager 。WifiManager wifiManager <- First is the Type, also known as class. The second one is the variable name. In your for loop you use the type/class instead of the variable, so just write wifiManager instead of WifiManager.您应该从理解OOP和Java的基础知识开始。认真地...在尝试写它之前学习语言... And you should definitively start by understanding the very basics of programming, OOP and Java. Seriously... Learn the language before you try to write it... 这篇关于如何编程android来寻找特定的网络？ （问题简单的教程）的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
