Wi-Fi扫描后，在android上显示当前Wi-Fi列表logcat
提问于 2017-04-28 12:07:10
我想要
首先，当前的Wi-Fi扫描。第二，如果Wi-Fi扫描完成，检查当前Wi-Fi列表。第三，在logcat上显示当前Wi-Fi列表。
我的来源
WifiManager wifi;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE);
registerReceiver(WifiReceiver, new IntentFilter(WifiManager.SCAN_RESULTS_AVAILABLE));
wifi.startScan();
}
private final BroadcastReceiver WifiReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals(WifiManager.SCAN_RESULTS_AVAILABLE_ACTION)) {
List<ScanResult> mScanResults = mWifiManager.getScanResults();
for (int i = 0; i < mScanResults.size(); i++) {
Log.d(TAG, "get current wifi lists ->" + mScanResults.get(i).toString());
}
}
}
}我想得到当前的wifi列表。
但mScanResults.get(i).toString());为空。
为什么value为空？如何获取当前wifi列表？

试试这个：
WifiManager wifi;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE);
if (wifi.isWifiEnabled() == false)
{
Toast.makeText(getApplicationContext(), "wifi is disabled..making it enabled", Toast.LENGTH_LONG).show();
wifi.setWifiEnabled(true);
}
wifi.startScan();
registerReceiver(WifiReceiver, new IntentFilter(WifiManager.SCAN_RESULTS_AVAILABLE_ACTION));
}
private final BroadcastReceiver WifiReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals(WifiManager.SCAN_RESULTS_AVAILABLE_ACTION)) {
List<ScanResult> mScanResults = mWifiManager.getScanResults();
for (int i = 0; i < mScanResults.size(); i++) {
Log.d(TAG, "get current wifi lists ->" + mScanResults.get(i).toString());
}
}
}
