要实现Android热点的Mac地址过滤功能,可以使用以下步骤:
public class HotspotReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
if (action.equals(WifiManager.WIFI_AP_STATE_CHANGED_ACTION)) {
int state = intent.getIntExtra(WifiManager.EXTRA_WIFI_AP_STATE, -1);
if (state == WifiManager.WIFI_AP_STATE_ENABLED) {
// 热点已启动,可以进行Mac地址过滤
enableMacAddressFilter(context);
} else if (state == WifiManager.WIFI_AP_STATE_DISABLED) {
// 热点已关闭,可以移除Mac地址过滤
disableMacAddressFilter(context);
}
}
}
private void enableMacAddressFilter(Context context) {
// 在这里添加Mac地址过滤的代码
}
private void disableMacAddressFilter(Context context) {
// 在这里移除Mac地址过滤的代码
}
}
private void enableMacAddressFilter(Context context) {
WifiManager wifiManager = (WifiManager) context.getApplicationContext().getSystemService(Context.WIFI_SERVICE);
wifiManager.setWifiApConfiguration(wifiManager.getWifiApConfiguration()); // 获取热点配置
wifiManager.setWifiApEnabled(null, true); // 重新启动热点
}
private void disableMacAddressFilter(Context context) {
WifiManager wifiManager = (WifiManager) context.getApplicationContext().getSystemService(Context.WIFI_SERVICE);
wifiManager.setWifiApConfiguration(wifiManager.getWifiApConfiguration()); // 获取热点配置
wifiManager.setWifiApEnabled(null, true); // 重新启动热点
}
这样,当Android热点启动时,会调用enableMacAddressFilter()方法来设置Mac地址过滤;当Android热点关闭时,会调用disableMacAddressFilter()方法来移除Mac地址过滤。
