怎样编程机器人寻找一个特定的网络？ （问题下面这个简单的教程） [英] How do I program android to look for a particular network? (Issues Following Simple Tutorial)
问题描述
我在尝试使用下面的例子：
<一个href=\"http://stackoverflow.com/questions/11060414/how-do-i-program-android-to-look-for-a-particular-network\">How我做Android的程序来寻找特定的网络？
但我无法执行它由于从线所产生的问题：
WifiManager wifiManager =（WifiManager）context.getSystemService（Context.WIFI_SERVICE）;
在那之后我得到其他几个错误 - 但[我觉得]我跟着教程/例如precisely。

您似乎混淆一些变量名：
WifiManager wifiManager =（WifiManager）context.getSystemService（Context.WIFI_SERVICE）;
wifiManager.add（CONF）;清单＆LT; WifiConfiguration＆GT;清单= wifiManager.getConfiguredNetworks（）;
对于（WifiConfiguration我：名单）{
如果（i.SSID = NULL＆放大器;！＆安培; i.SSID.equals（\\+ networkSSID +\\））{
wm.disconnect（）;
wm.enableNetwork（i.networkId，真）;
wm.reconnect（）;
打破;
}
}
wifiManager 应 WM ，反之亦然。此外背景应这个或只是抛弃了，因为 getSystemService（）是你的类的方法。
我不知道有关与）的问题，添加（ ...
修改
好添加（）为 WifiManager ，但 addNetwork（）呢，所以我想你需要的方法，而不是添加（）
EDIT2
你根本不知道你在做什么，对不对？你甚至不明白一个类名和变量名之间的差别！
WifiManager wifiManager ＆LT; - 首先是类型，也被称为类。第二个是变量名。在你的为循环使用类型/类而不是变量，所以只写 wifiManager 而不是 WifiManager 。
你应该明确地通过了解编程，面向对象和Java基础做起。认真...学习语言，你得试着写一个前...
I'm attempting to use the following example:
How do I program android to look for a particular network?
But I'm unable to execute it due to issues stemming from the line:
WifiManager wifiManager = (WifiManager)context.getSystemService(Context.WIFI_SERVICE);
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;
}
}
}}
ISSUES IN ECLIPSE PROBLEM LOG:

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 should be wm or vice versa. Also context should be this or just left out as getSystemService() is a method of your class.
I am not sure about the issue with add()...
Edit:
Well add() does not exist for WifiManager but addNetwork() does, so I guess you need that method instead of add()
Edit2:
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 <- 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.
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...
