How can I connect to a specific wifi network? - java

I have devlope project to list out all wifi connection available near to my device.Now, I want to connect any one specific network connection.
SO what can I do? I have got all networks in listview.
If any example available then post comment link.
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;
}
}
}
});
}
});
}
and also dialog
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();
}
and in onCreate but you could skip creating WifiItems and just store SSIDs
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);
}

If RecyclerView scrolls, then item id changes. How to resolve this?

This is my PDFListAdapter class method. I have downloaded file locally and save on Sqlite database. But if I scroll my RecyclerView, then I am having different item id. If not scroll RecyclerView then item id is perfect.
The problem is when I scroll down the RecyclerView the item id changes. That is, I can fit one item on the screen at once. When I scroll to the second item, it saves different file and opens different.

I have modified your onBindViewHolder function. The changes are following.
Declared the pdfList variable as final and used it everywhere. It is not necessary to get the pdfList from the pdfModelClasses, each time you use it.
The holder variable is removed, as it is not actually necessary. The holder1 is used everywhere.
There are some changes with the visibility of the buttons. Check holder1.imgDownloadNote.setOnClickListener.
I have found no other problem in your onBindViewHolder. Please let me know if the modified code works.

The link to the full code is : https://drive.google.com/open?id=1aQFcWHinIqqXHbTyssfPYTD20o9E2piA
and if you can’t find the java files here they are: https://drive.google.com/drive/folders/1VKp0CoJlJssSdKzK4ctk26KFY0_xIDzU?usp=sharing

In your onLoadFinished you assume mPictureURI is set and is not empty.
Now you have set a listener on mProductImageView for changes. No matter what you write/set down below the mProductImageView finally the in the listener it was set back to mPictureURI which was empty hence showing an empty image space.
Please have a look at the code below(also verified that it works).

Google Cloud Speech API for Android

Currently I`m working on a project where i have to use Google Cloud Speech Api and TextToSpeech. I try-ed to work around with RecognizerIntent but i would like to give a try to Cloud Speech .
Would be great some tutorial material or guide , i checked the sample app
but i`m looking for tutorial , guide anything that could explain something.

Setting up Google Speech cloud on Android is not a straightforward 1,2,3 process, but I will give you some guidance.
Download the Sample project from here, use the Speech example.
https://github.com/GoogleCloudPlatform/android-docs-samples/tree/master/speech/Speech
Setup a google cloud project, enable the Speech API, and link it to
your gmail account's billing (you get 60min of free speech recognition
every month).
Generate an authentication json, and put it into the "raw" folder of
the sample project.
Setup Google cloud on your computer and obtain an access token.
Insert that access token on your SpeechService.java class.
*Documentation on steps 3 and 4:
https://cloud.google.com/speech/docs/getting-started
*If you run into problems when trying to mimic the sample project into your own project, check this:
Cannot import com.google.cloud.speech.v1.SpeechGrpc in Android
The exact steps are too long to list, I can't even remember them all, if you run into specific trouble let me know.

I know code is a mess. But any help will be appreciated.
Thanks! :)

Make sure you have the same name as property in your service and android parameters, for example request.addProperty("name",name) in the WebService public class Login(String name)
