现需求，当用户开机的时候要进行用户登录与注册。没联网要进行wifi连接，坑爹的是要求引导用户进行wifi连接，所以要做一个简单的wifi连接跳到登录页面的操作。
解决方案：
1.获取wifi列表，也就是扫描wifi，很简单，网上代码一大把。
/**
* 扫描wifi
*/
public void startScan() {
mWifiManager.startScan();
// 得到扫描结果
mWifiList = mWifiManager.getScanResults();
// 得到配置好的网络连接
mWifiConfigurations = mWifiManager.getConfiguredNetworks();
}2.连接wifi。连接wifi好像就是指给wifi添加配置信息，大概的意思是，当你手动连接wifi的时候，输入密码，就相当于给这个wifi添加配置信息的意思。
/**
* 添加指定WIFI的配置信息,原列表不存在此SSID
*
* @param wifiList
* @param ssid
* @param pwd
* @return
*/
public int AddWifiConfig(List<ScanResult> wifiList, String ssid, String pwd) {
int wifiId = -1;
for (int i = 0; i < wifiList.size(); i++) {
ScanResult wifi = wifiList.get(i);
if (wifi.SSID.equals(ssid)) {
Log.i("AddWifiConfig", "equals");
WifiConfiguration wifiCong = new WifiConfiguration();
wifiCong.SSID = "\"" + wifi.SSID + "\"";// \"转义字符，代表"
wifiCong.preSharedKey = "\"" + pwd + "\"";// WPA-PSK密码
wifiCong.hiddenSSID = false;
wifiCong.status = WifiConfiguration.Status.ENABLED;
wifiId = mWifiManager.addNetwork(wifiCong);// 将配置好的特定WIFI密码信息添加,添加完成后默认是不激活状态，成功返回ID，否则为-1
if (wifiId != -1) {
return wifiId;
}
}
}
return wifiId;
}3.如何判定当前的wifi连接成功，期初想法是获得当前要连的wifi的SSID，可能会拿到密码，与我的密码做比较，但转念一想，wifi的真实密码，是不可能外部透露的。看到百度上别人写的：配置完wifi的信息，再获取一遍WifiInfo,拿到wifiinfo里的ssid与当前我要连接的wifi的ssid比较，如果一致就是连接正确，但亲测有问题。于是我就想这么来:
RxView.clicks(btn_conn).throttleFirst(1, TimeUnit.SECONDS).subscribe(new Action1<Void>() {
@Override
public void call(Void aVoid) {
pwd=et_pwd.getText().toString();
//Toast.makeText(WifiActivity.this,currentSSID,Toast.LENGTH_SHORT).show();
if (pwd!=null&& !TextUtils.isEmpty(pwd)&¤tSSID!=null&&!TextUtils.isEmpty(currentSSID)){
ProjectUtils.showDialog(WifiActivity.this);
int wifiItemId = wiFiUtils.IsConfiguration("\""
+ currentSSID + "\"");
/* if (wifiItemId != -1) {
if (wiFiUtils.ConnectWifi(wifiItemId)) {
// 连接已保存密码的WiFi
ProjectUtils.dismissDialog();
Toast.makeText(getApplicationContext(), "正在连接",
Toast.LENGTH_SHORT).show();
}
}else{*/
//链接wifi
int netId = wiFiUtils
.AddWifiConfig(wifiList,
currentSSID,
pwd);
if (netId!=-1){
wiFiUtils.getConfiguration();// 添加了配置信息，要重新得到配置信息
wiFiUtils.ConnectWifi(netId);
final int countTime = 0;
RxUtils.unsubscribe(subscription);
subscription = Observable.interval(0, 1, TimeUnit.SECONDS)
.observeOn(AndroidSchedulers.mainThread())
.map(new Func1<Long, String>() {
@Override
public String call(Long aLong) {
return new SimpleDateFormat("ss").format((countTime + aLong.intValue()) * 1000);
}
}).subscribe(new Action1<String>() {
@Override
public void call(String s) {
WifiInfo wifiInfo = wiFiUtils.getmWifiManager().getConnectionInfo();
// wifiInfo.getState().equals(NetworkInfo.State.CONNECTED)
Log.i("Wifi扫描ING::",s+"/"+wifiInfo.getSSID());
if (s.equals("05")) {
if (ProjectUtils.isNetworkAvailable(WifiActivity.this)){
ProjectUtils.dismissDialog();
// if (wifiInfo.getSSID().contains(currentSSID)) {
RxUtils.unsubscribe(subscription);
Toast.makeText(WifiActivity.this,"Wifi连接成功",Toast.LENGTH_SHORT).show();
startActivity(new Intent(WifiActivity.this,UserLoginActivity.class));
Log.i("Wifi扫描结果::", "Success");
// }
}
} else if (s.equals("10")) {
ProjectUtils.dismissDialog();
if (!ProjectUtils.isNetworkAvailable(WifiActivity.this)){
RxUtils.unsubscribe(subscription);
Log.i("Wifi扫描结果::", "ERROR");
Toast.makeText(WifiActivity.this,"密码不正确",Toast.LENGTH_SHORT).show();
et_pwd.setText("");
}else{
ProjectUtils.dismissDialog();
RxUtils.unsubscribe(subscription);
Toast.makeText(WifiActivity.this,"Wifi连接成功",Toast.LENGTH_SHORT).show();
startActivity(new Intent(WifiActivity.this,UserLoginActivity.class));
Log.i("Wifi扫描结果::", "Success");
}
}
}
});
// RxUtils.countUpTime()
/* Toast.makeText(WifiActivity.this,"连接"+currentSSID+"成功",Toast.LENGTH_SHORT).show();
if () {
// 连接成功，刷新UI
ProjectUtils.dismissDialog();
}
*/
}else {
ProjectUtils.dismissDialog();
Toast.makeText(WifiActivity.this,"密码必须是八位",Toast.LENGTH_SHORT).show();
et_pwd.setText("");
}
// }
}else{
if (TextUtils.isEmpty(pwd)){
Toast.makeText(WifiActivity.this,"请输入wifi密码",Toast.LENGTH_SHORT).show();
}
}
}
});大概的意思是,配置完wifi信息的时候，我起一个线程计时，如果10s内有网就说明wifi连接成功了，没有就密码错了，因为现在基本都是rxjava那一套，线程也相当好控制。不知道大家有没有更加好的方法。
