开启android手机的wifi热点

来源：互联网发布：域名再长我也记得住编辑：程序博客网时间：2024/04/30 01:16

因为无线wifi不能和wufi热点同时打开,所以开启wifi热点的时候要监测是否打开了wifi,打开了就要关闭

[java] view plaincopy

wifiManager = (WifiManager) this.getSystemService(Context.WIFI_SERVICE);

[java] view plaincopy

private void startWifiAp() {
handler = new Handler();
if (wifiManager.isWifiEnabled()) {
closeWifiHandler = new Handler() {
@Override
public void handleMessage(Message msg) {
startWifiApTh();
super.handleMessage(msg);
}
};
cwt = new CloseWifiThread();
Thread thread = new Thread(cwt);
thread.start();
}else{
startWifiApTh();
}
}
class CloseWifiThread implements Runnable {
public CloseWifiThread() {
super();
}
@Override
public void run() {
int state = wifiManager.getWifiState();
if (state == WifiManager.WIFI_STATE_ENABLED) {
wifiManager.setWifiEnabled(false);
closeWifiHandler.postDelayed(cwt, 1000);
} else if (state == WifiManager.WIFI_STATE_DISABLING) {
closeWifiHandler.postDelayed(cwt, 1000);
}else if(state == WifiManager.WIFI_STATE_DISABLED){
closeWifiHandler.sendEmptyMessage(0);
}
}
}
private void startWifiApTh(){
swat = new StratWifiApThread();
Thread thread = new Thread(swat);
thread.start();
}
class StratWifiApThread implements Runnable {
public StratWifiApThread() {
super();
}
@Override
public void run() {
// TODO Auto-generated method stub
WifiUtil mWifiUtil = new WifiUtil();
int state = mWifiUtil.getWifiApState(wifiManager);
if (state == WifiUtil.WIFI_AP_STATE_DISABLED) {
mWifiUtil.stratWifiAp(wifiManager);
handler.postDelayed(swat, 1000);
} else if (state == WifiUtil.WIFI_AP_STATE_ENABLING
|| state == WifiUtil.WIFI_AP_STATE_FAILED) {
handler.postDelayed(swat, 1000);
}else if (state == WifiUtil.WIFI_AP_STATE_ENABLED){
Toast.makeText(ActivityForAndroid.this, "已开启wlan热点", 2000).show();
}
}
}

[java] view plaincopy

public void stratWifiAp(WifiManager wifiManager) {
// WifiManager wifi = (WifiManager)

// wifiManager.setWifiEnabled(false);
Method method1 = null;
try {

WifiConfiguration.class, boolean.class);
WifiConfiguration netConfig = new WifiConfiguration();
//wifi热点名字
netConfig.SSID = "\" T E S T \"";

}
public int getWifiApState(WifiManager wifiManager) {
try {
Method method = wifiManager.getClass().getMethod("getWifiApState");
int i = (Integer) method.invoke(wifiManager);
Log.i("wifi state: " + i);
return i;
} catch (Exception e) {
Log.i("Cannot get WiFi AP state" + e);
return WIFI_AP_STATE_FAILED;
}
}
}

上面的代码用到handler每隔1秒post线程来监测是否关闭了wifi 和是否打开了wifi热点..不知道还有没有其他更好的方法..

wifiutil类的打开wifi热点的代码用到java的反射类还在学习..
