Formatting errors - issues with code formation

Formatting errors - issues with code formation - java

I have experienced various minor errors with forming my code, and is having difficulty resolving them.
In particular, I have the following line underline with the following message
query.findInBackground(new FindCallback<ParseObject>() {
The method findInBackground(FindCallback<ParseUser>) in the type ParseQuery<ParseUser> is not applicable for the arguments (new FindCallback<ParseObject>(){})
As well as errors closing my statements.
and finally
Below is the complete code
Any help would be greatly appreciated. Thanks in advance

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)

How can I connect to a specific wifi network?

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() {

// 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,

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")) {

}
//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);
}

Update
I have added another picture

You didn't post enough code to show where the missing or extra bracket is. Just go through your code carefully, work your way outward, collapsing methods etc as you go.

I think you should have something like below to iterate over the list:
query.findInBackground(new FindCallback<ParseUser>() {
#Override
public void done(List<ParseObject> objects,ParseException e) {
for(int i=0;i<objects.size();i++){
// Do whatever you need to extract object from "users"
ParseQuery<ParseObject> query = ParseQuery.getQuery("User");
ParseFile image = objects.get(i).getParseFile("ProfilePicture");
ParseImageView imageView = (ParseImageView) getView().findViewById(R.id.profilePictureResult);
// The placeholder will be used before and during the fetch, to be replaced by the fetched image
// data.
imageView.setPlaceholder(getResources().getDrawable(R.drawable.profile_pict));
imageView.setParseFile(image);
imageView.loadInBackground(new GetDataCallback() {
#Override
public void done(byte[] data, ParseException e) {
Log.i("ParseImageView",
"Fetched! Data length: " + data.length + ", or exception: " + e.getMessage());
}
});
}
}//for loop
});

Retrieving files on Parse - Images

I have already managed to store image files into parse. My question lies in retrieving it. In the sense that in the registration process users are asked to upload a profile picture, and where the image is later stored into parse as an image. My issue lies in retrieving it, where along with pulling information like name, headline, age for a potential match, I also want to be able to retrieve the picture.
Below is the code, where I retrieve string information, but where I would want to retrieve files as well.
public class MatchingActivity extends Activity {
private String currentUserId;

private ArrayList<String> names;

Number maxDistance = ParseUser.getCurrentUser().getNumber("Maximum_Distance");
String userLookingGender = ParseUser.getCurrentUser().getString("Looking_Gender");

Number userage = ParseUser.getCurrentUser().getNumber("Age");

see if something like below would help:
ParseUser currentUser = ParseUser.getCurrentUser();
currentUser.fetchInBackground(new GetCallback<ParseObject>() {
public void done(ParseObject object, ParseException e) {
if (e == null) {
ParseFile file = (ParseFile)object.get("image");
if(file != null){
file.getDataInBackground(new GetDataCallback() {
public void done(byte[] data, ParseException e) {
if (e == null) {
Bitmap bitmap = BitmapFactory.decodeByteArray(data, 0, data.length);
if(bitmap != null){
imageAccount.setImageBitmap(bitmap);
}else{
Log.d(TAG, "file null?");
}
} else {
Log.d(TAG, "ParseFile ParseException: " + e.toString());
}
}
});
}else{
Log.d(TAG, "ParseFile is null");
}
} else {
Log.d(TAG, "ParseException: " + e.toString());
}
}
});

When you store a pointer to type 'file' in parse, u get a URL and a name .
Anytime you have reference to the file, you should be able to also get the URL.
Use the URL to do an async get and to generate a local bitmap for using the photo in a view.

Parse whereEqualTo

I am trying to retrieve information from parse. In particular, I have added a condition where it would only return the list of users that have selected the same activity.
I have tried the below code, but it does seem to work, as that condition returns an empty list.
ParseQuery<ParseUser> query = ParseUser.getQuery();
query.whereNotEqualTo("objectId", currentUserId);
query.whereEqualTo("ActivityName","");
It would essentially see which users have selected that particular activity name and return
Below is the entire code
public class MatchingActivity extends Activity {
private String currentUserId;
private ArrayAdapter<String> namesArrayAdapter;
private ArrayList<String> names;
private ListView usersListView;
private Button logoutButton;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.matching);
logoutButton = (Button) findViewById(R.id.logoutButton);
logoutButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
ParseUser.logOut();
Intent intent = new Intent(getApplicationContext(), LoginActivity.class);
startActivity(intent);
}
});
setConversationsList();
}
private void setConversationsList() {
currentUserId = ParseUser.getCurrentUser().getObjectId();
names = new ArrayList<String>();
ParseQuery<ParseUser> query = ParseUser.getQuery();
query.whereNotEqualTo("objectId", currentUserId);
query.whereEqualTo("ActivityName",userActivitySelectionName);
query.findInBackground(new FindCallback<ParseUser>() {
public void done(List<ParseUser> userList, ParseException e) {
if (e == null) {
for (int i=0; i<userList.size(); i++) {
names.add(userList.get(i).getUsername().toString());
}
usersListView = (ListView)findViewById(R.id.usersListView);
namesArrayAdapter =
new ArrayAdapter<String>(getApplicationContext(),
R.layout.user_list_item, names);
usersListView.setAdapter(namesArrayAdapter);
usersListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> a, View v, int i, long l) {
openConversation(names, i);
}
});
} else {
Toast.makeText(getApplicationContext(),
"Error loading user list",
Toast.LENGTH_LONG).show();
}
}
});
}
public void openConversation(ArrayList<String> names, int pos) {
ParseQuery<ParseUser> query = ParseUser.getQuery();
query.whereEqualTo("username", names.get(pos));
query.findInBackground(new FindCallback<ParseUser>() {
public void done(List<ParseUser> user, ParseException e) {
if (e == null) {
Intent intent = new Intent(getApplicationContext(), MessagingActivity.class);
intent.putExtra("RECIPIENT_ID", user.get(0).getObjectId());
startActivity(intent);
} else {
Toast.makeText(getApplicationContext(),
"Error finding that user",
Toast.LENGTH_SHORT).show();
}
}
});
}
}
Thanks in advance.

Double-check in the Data Browser, but I'm guessing that the column has "undefined" instead of an empty string.
In this case you'll need to use the following:
query.whereDoesNotExist("ActivityName");
The whereDoesNotExist() and whereExists() functions are for checking if there is any value set on a column.
