我有devlope项目列出了我设备附近所有可用的wifi连接。现在，我想连接任何一个特定的网络连接。那我该怎么办？我的所有网络都在列表视图中。如果有任何示例，请发表评论链接。
private void getWifiNetworksList() {
IntentFilter filter = new IntentFilter();
filter.addAction(WifiManager.SCAN_RESULTS_AVAILABLE_ACTION);
final WifiManager wifiManager = (WifiManager) getApplicationContext()
.getSystemService(Context.WIFI_SERVICE);
;
registerReceiver(new BroadcastReceiver() {
@SuppressLint("UseValueOf")
@Override
public void onReceive(Context context, Intent intent) {
sb = new StringBuilder();
scanList = wifiManager.getScanResults();
sb.append("\n Number Of Wifi connections :" + " "
+ scanList.size() + "\n\n");
adapter = new ArrayAdapter<String>(DraginoActivity.this,
android.R.layout.simple_list_item_1, list);
adapter.clear();
for (int i = 0; i < scanList.size(); i++) {
listWifiDevice.setAdapter(adapter);
// list.add(new Integer(i + 1).toString() + ". ");
list.add((new Integer(i + 1).toString() + ". ")
+ (scanList.get(i)).toString().substring(5,
(scanList.get(i)).toString().indexOf(",")));
// list.add("\n\n");
listWifiDevice.setAdapter(adapter);
adapter.notifyDataSetChanged();
listWifiDevice
.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> arg0,
View arg1, int arg2, long arg3) {
TextView tv = (TextView) arg1;
// TODO Auto-generated method stub
Toast.makeText(DraginoActivity.this,
"" + tv.getText().toString(), 1000)
.show();
}
});
}
// listWifiDevice.setAdapter(adapter);
}
}, filter);
wifiManager.startScan();
}
private void setNetworksList() {
networksList = (ListView) findViewById(R.id.networkList);
networksList.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, final int position,
long id) {
final int chosenPosition = position;
WiFiItem wifiItem = new WiFiItem();
wifiItem = (WiFiItem) parent.getItemAtPosition(position);
networkSSID = wifiItem.getSSID();
networkPass = "";
showPasswordDialog(ConnectActivity.this);
setPasswordListener(new PasswordTypedListener() {
@Override
public void onPasswordTyped() {
connectHelper = new ConnectHelper();
if(scanResult.get(chosenPosition).capabilities.contains("WEP")) {
connectHelper.setupConnection(networkSSID, networkPass, "WEP");
}
//jezeli siec WPA
else if(scanResult.get(chosenPosition).capabilities.contains("WPA")) {
connectHelper.setupConnection(networkSSID, networkPass, "WPA");
}
//inne przypadki (open network)
else {
connectHelper.setupConnection(networkSSID, networkPass, "ELSE");
}
wifiManager.addNetwork(connectHelper.getConfiguration());
List<WifiConfiguration> list = wifiManager.getConfiguredNetworks();
for( WifiConfiguration i : list ) {
if(i.SSID != null && i.SSID.equals("\"" + networkSSID + "\"")) {
wifiManager.disconnect();
wifiManager.enableNetwork(i.networkId, true);
if(wifiManager.reconnect()) {
for(int j=0;j<listWifi.size();j++){
listWifi.get(j).setConnected(false);
}
runnableCounter=0;
handler.postDelayed(ifConnected,1000);
}
break;
}
}
}
});
}
});
}
还有对话框
private void showPasswordDialog(Context context) {
final EditText input = new EditText(context);
input.setSingleLine();
AlertDialog.Builder alert = new AlertDialog.Builder(context);
alert.setTitle("PASSWORD");
alert.setView(input);
alert.setPositiveButton("Confirm", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
networkPass = input.getText().toString();
if(ConnectActivity.this.passwordListener != null)
ConnectActivity.this.passwordListener.onPasswordTyped();
}
});
alert.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
}
});
alert.show();
}
并在onCreate中，但是您可以跳过创建WifiItems并仅存储SSID
ArrayList<WiFiItem> listWifi = new ArrayList<WiFiItem>();
wifiManager.startScan();
scanResult = wifiManager.getScanResults();
for(ScanResult sc : scanResult) {
WiFiItem wifiItem = new WiFiItem();
wifiItem.setSSID(sc.SSID);
wifiItem.setBSSID(sc.BSSID);
listWifi.add(wifiItem);
}
