android studio开发的app设置热点代码

在Android Studio中开发App设置热点的代码如下：

1. 添加权限到AndroidManifest.xml文件：

<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.WRITE_SETTINGS" />
<uses-permission android:name="android.permission.WRITE_SECURE_SETTINGS" />

2. 创建一个类来设置热点：

public class WifiApManager {
    private final WifiManager mWifiManager;

    public WifiApManager(Context context) {
        mWifiManager = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
    }

    public boolean setWifiApEnabled(WifiConfiguration config, boolean enabled) {
        try {
            if (enabled) {
                mWifiManager.setWifiEnabled(false);
            }

            Method method = mWifiManager.getClass().getMethod("setWifiApEnabled", WifiConfiguration.class, boolean.class);
            return (Boolean) method.invoke(mWifiManager, config, enabled);
        } catch (Exception e) {
            e.printStackTrace();
        }

        return false;
    }
}

3. 在MainActivity中调用该类来设置热点：

WifiApManager wifiApManager = new WifiApManager(MainActivity.this);
WifiConfiguration config = new WifiConfiguration();
config.SSID = "My Hotspot";
config.preSharedKey = "password";
wifiApManager.setWifiApEnabled(config, true);

注意：需要在AndroidManifest.xml文件中添加相关权限，并且设备必须支持热点功能。
