Android以编程方式打开/关闭WiFi HotSpot

请使用以下课程更改/检查“ 0”设置：

import android.content.*;
import android.net.wifi.*;
import java.lang.reflect.*;

public class ApManager {

//check whether wifi hotspot on or off
public static boolean isApOn(Context context) {
    WifiManager wifimanager = (WifiManager) context.getSystemService(context.WIFI_SERVICE);     
    try {
        Method method = wifimanager.getClass().getDeclaredMethod(\"isWifiApEnabled\");
        method.setAccessible(true);
        return (Boolean) method.invoke(wifimanager);
    }
    catch (Throwable ignored) {}
    return false;
}

// toggle wifi hotspot on or off
public static boolean configApState(Context context) {
    WifiManager wifimanager = (WifiManager) context.getSystemService(context.WIFI_SERVICE);
    WifiConfiguration wificonfiguration = null;
    try {  
        // if WiFi is on, turn it off
        if(isApOn(context)) {               
            wifimanager.setWifiEnabled(false);
        }               
        Method method = wifimanager.getClass().getMethod(\"setWifiApEnabled\", WifiConfiguration.class, boolean.class);                   
        method.invoke(wifimanager, wificonfiguration, !isApOn(context));
        return true;
    } 
    catch (Exception e) {
        e.printStackTrace();
    }       
    return false;
}
} // end of class

您需要将以下权限添加到您的AndroidMainfest中：

<uses-permission android:name=\"android.permission.CHANGE_NETWORK_STATE\" />
<uses-permission android:name=\"android.permission.CHANGE_WIFI_STATE\" />
<uses-permission android:name=\"android.permission.ACCESS_WIFI_STATE\" />

可以在任何地方使用此独立的ApManager类，如下所示：

ApManager.isApOn(YourActivity.this); // check Ap state :boolean
ApManager.configApState(YourActivity.this); // change Ap state :boolean

希望这会帮助某人

Android SDK中没有与WiFi热点功能相关的方法-抱歉！

对于Android 8.0，有一个新的API处理热点。据我所知，使用反射的旧方法不再起作用。请参阅： Android开发人员 https://developer.android.com/reference/android/net/wifi/WifiManager.html#startLocalOnlyHotspot(android.net.wifi.WifiManager.LocalOnlyHotspotCallback,%20android.os.Handler）

void startLocalOnlyHotspot (WifiManager.LocalOnlyHotspotCallback callback, 
                Handler handler)

请求应用程序可以用来在与创建的WiFi热点相连的同位设备之间进行通信的仅本地热点。通过此方法创建的网络将无法访问Internet。堆栈溢出如何在Android 8.0（Oreo）中以编程方式打开/关闭wifi热点如果启用了热点，则将调用onStarted（WifiManager.LocalOnlyHotspotReservation保留）方法。使用WifiManager.LocalOnlyHotspotReservation参考，您可以调用close（）方法来关闭热点。

这对我来说很好：

WifiConfiguration apConfig = null;
Method method = wifimanager.getClass().getMethod(\"setWifiApEnabled\", WifiConfiguration.class, Boolean.TYPE);
method.invoke(wifimanager, apConfig, true);

骨乏唯瓜

仅适用于Oreo + ... 我在GitHub上使用代码创建了一个应用，该应用使用反射和DexMaker来“获取” Oreo的网络共享功能，该功能现在是in7ѭ，而不是WifiManager。 ѭ8中的内容仅对封闭的wifi网络有用（这解释了类名中的Closed位！）。更多说明https://stackoverflow.com/a/49356255/772333。

田损比报

最好的选择是看WifiManager类。特别是“ 10”功能。请参阅以下文档： http://developer.android.com/reference/android/net/wifi/WifiManager.html#setWifiEnabled(boolean）有关如何使用它（包括所需的权限）的教程，可以在这里找到： http://www.tutorialforandroid.com/2009/10/turn-off-turn-on-wifi-in-android-using.html

我已经发布了非官方的api，它不仅包含热点，还包含turn11ѭ。链接对于API的DOC-链接。

我们可以以编程方式打开和关闭

setWifiApDisable.invoke(connectivityManager, TETHERING_WIFI);//Have to disable to enable
setwifiApEnabled.invoke(connectivityManager, TETHERING_WIFI, false, mSystemCallback,null);

使用回调类，以编程方式打开pie（9.0）中的热点，您需要以编程方式关闭然后打开。

长拳

您可以为该选项使用控制台和服务。我认为您可以解决这个问题。我直接在控制台中进行了测试并启用了热点我在这篇文章中找到了是否可以通过终端使用adb USB绑定Android设备？读取接口后，我们可以使用相同的24个，但需要更多参数服务呼叫连通性24 i32 0 i32 1 i32 0 s16随机

捅瓶啡

如果您想在Android应用中以编程方式实现wifi热点功能，则这里是完整的解决方案。 API <26的解决方案：对于

  <uses-permission  
  android:name=\"android.permission.WRITE_SETTINGS\"  
  tools:ignore=\"ProtectedPermissions\"/>

  <uses-permission android:name=\"android.permission.ACCESS_NETWORK_STATE\"/>
  <uses-permission android:name=\"android.permission.CHANGE_WIFI_STATE\"/>
  <uses-permission android:name=\"android.permission.ACCESS_WIFI_STATE\"/>

您可以在运行时提出以下要求：

 private boolean showWritePermissionSettings() {    
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M  
    && Build.VERSION.SDK_INT < Build.VERSION_CODES.O) { 
  if (!Settings.System.canWrite(this)) {    
    Log.v(\"DANG\", \" \" + !Settings.System.canWrite(this));   
    Intent intent = new Intent(android.provider.Settings.ACTION_MANAGE_WRITE_SETTINGS); 
    intent.setData(Uri.parse(\"package:\" + this.getPackageName()));  
    intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 
    this.startActivity(intent); 
    return false;   
  } 
}   
return true; //Permission already given 
}

然后，您可以通过反射访问setWifiEnabled方法。如果您要执行的操作已正确处理（即启用/禁用热点），则返回true。

     public boolean setWifiEnabled(WifiConfiguration wifiConfig, boolean enabled) { 
 WifiManager wifiManager;
try {   
  if (enabled) { //disables wifi hotspot if it\'s already enabled    
    wifiManager.setWifiEnabled(false);  
  } 

   Method method = wifiManager.getClass()   
      .getMethod(\"setWifiApEnabled\", WifiConfiguration.class, boolean.class);   
  return (Boolean) method.invoke(wifiManager, wifiConfig, enabled); 
} catch (Exception e) { 
  Log.e(this.getClass().toString(), \"\", e); 
  return false; 
}   
}

您还可以通过反射获取热点的wifi配置。我已经在StackOverflow上针对该问题回答了该方法。附注：如果您不想以编程方式打开热点，则可以启动此意图并打开wifi设置屏幕，以便用户手动将其打开。 API> = 26的解决方案：最终，android发布了版本> = Oreo的官方API。您可以通过android使用公开的公开API，例如startLocalOnlyHotspot 它打开了没有互联网访问的本地热点。因此可以用来托管服务器或传输文件。它需要“ 19”和“ 20”权限。这是一个简单的示例，说明如何使用此API打开热点。

private WifiManager wifiManager;
WifiConfiguration currentConfig;
WifiManager.LocalOnlyHotspotReservation hotspotReservation;

开启热点的方法：

@RequiresApi(api = Build.VERSION_CODES.O)
public void turnOnHotspot() {

      wifiManager.startLocalOnlyHotspot(new WifiManager.LocalOnlyHotspotCallback() {

        @Override
        public void onStarted(WifiManager.LocalOnlyHotspotReservation reservation) {
          super.onStarted(reservation);
          hotspotReservation = reservation;
          currentConfig = hotspotReservation.getWifiConfiguration();

          Log.v(\"DANG\", \"THE PASSWORD IS: \"
              + currentConfig.preSharedKey
              + \" \\n SSID is : \"
              + currentConfig.SSID);

          hotspotDetailsDialog();

        }

        @Override
        public void onStopped() {
          super.onStopped();
          Log.v(\"DANG\", \"Local Hotspot Stopped\");
        }

        @Override
        public void onFailed(int reason) {
          super.onFailed(reason);
          Log.v(\"DANG\", \"Local Hotspot failed to start\");
        }
      }, new Handler());
    }
`

这是如何获取本地创建的热点的详细信息

private void hotspotDetaisDialog()
{

    Log.v(TAG, context.getString(R.string.hotspot_details_message) + \"\\n\" + context.getString(
              R.string.hotspot_ssid_label) + \" \" + currentConfig.SSID + \"\\n\" + context.getString(
              R.string.hotspot_pass_label) + \" \" + currentConfig.preSharedKey);

}

如果抛出该异常，即使在授予必需的权限后也会出现安全异常，那么您应该尝试使用GPS启用位置。这是解决方案。最近，我开发了一个名为Spotserve的演示应用程序。这会为所有API> = 15的设备打开wifi热点，并在该热点上托管一个演示服务器。您可以检查更多细节。希望这可以帮助！
