I've implemented one code to scan the wifi networks and display them in the list. After selecting one of the wifi networks from the list, I have added selected network in another activity in another ListView.
Now when I restart the app and again scan the wifi networks, I'm getting that network also which I have selected before and added in the list.
(In one activity I'm searching available wifi networks and in other activity I have added list of that selected networks)
So my question is that, how to hide that network which I have already added in list view?
This is my first activity, here i have displayed the added device in listview
#Override

{
listView = (ListView)findViewById(R.id.device_list);
devicesNameEspNum = new ArrayList<>();
devices = new Devices();
devicesList = alldeviceList();
for(int i=0; i<devicesList.size(); i++)
{
devices = devicesList.get(i);
devicesNameEspNum.add(devices);
}
devicesAdapter = new DevicesAdapter(MainActivity.this,devicesNameEspNum);
listView.setAdapter(devicesAdapter);
devicesAdapter.notifyDataSetChanged();
}
catch (NullPointerException ex)

ex.printStackTrace();
}
listView.setOnItemClickListener(new AdapterView.OnItemClickListener()
{
#Override
public void onItemClick(AdapterView<?> adapter, View view, int position, long id)
{
Intent intent = new Intent(MainActivity.this,Fourth.class);
String selected = ((TextView) view.findViewById(R.id.deviceNamList)).getText().toString();
intent.putExtra("DEVICE_ID",selected);
startActivity(intent);
finish();
}
});
final LocationManager manager = (LocationManager) getSystemService( Context.LOCATION_SERVICE );

{
Toast.makeText(this, "****", Toast.LENGTH_SHORT).show();
}
}
public static List<Devices> alldeviceList()
{
return new Select().from(Devices.class).execute();
}
This is my second activity to scan nearby wifi networks
#Override

// listening to single list item on click
list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
// selected item
String ssid = ((TextView) view).getText().toString();
connectToWifi(ssid);
Toast.makeText(Second.this,"Wifi SSID : "+ssid,Toast.LENGTH_SHORT).show();
}
});
}
This is the class:
class WifiScanReceiver extends BroadcastReceiver
{
#SuppressLint("UseValueOf")
public void onReceive(Context c, Intent intent)
{
List<ScanResult> wifiScanList = mainWifiObj.getScanResults();
System.out.println("Wifi Scan Result: "+wifiScanList);
wifis = new String[wifiScanList.size()];
for(int i = 0; i < wifiScanList.size(); i++)
{
wifis[i] = ((wifiScanList.get(i)).toString());
}
String filtered[] = new String[wifiScanList.size()];
int counter = 0;
for (String eachWifi : wifis) {
String[] temp = eachWifi.split(",");
filtered[counter] = temp[0].substring(5).trim();//+"\n" + temp[2].substring(12).trim()+"\n" +temp[3].substring(6).trim();//0->SSID, 2->Key Management 3-> Strength
counter++;
}
System.out.println("Filtered :"+filtered);
list.setAdapter(new ArrayAdapter<String>(getApplicationContext(),R.layout.list_item,R.id.label, filtered));
}
}
What's about this ?
displayed.addAll(allItems.filter { !it.equals("abc") })

I have a working app using threads in fragments, the thing is I need to change the layout. It's not gonna be a Fragment anymore but a standard Activity.
My big problem is that I don't know exactly where to place what's in "onViewCreated" and "onCreateView" so it's crashing when I call "connect to device" which's placed on "onCreateView". Probably because it's too early or something.

Regarding you error

Maybe add that code in the Activity onResume() lifecykle method instead of onCreate if it need to run more then one time
Move the scanningThread, BluetoothAdapter and LocalBroadcastManager LibCore everything to the 'onCreate()' . The 'onCreateView()' should only have the view = inflater.inflate(R.layout.fragment_home_2, container, false);
The onCreate() only initiate stuff hook up local variables views and set clicklisteners. Like all the one-time-stuff. Going from Fragment to Activity is basically almost the same since they have the same lifecykle methods
Check this nice explanation about the-android-lifecycle-cheat-sheet
I created an application which gets values from previous activity as extras and uses that values in that activity. And the values are then sent to another activity. But when I returned back from the moving activity to previous activity the extra values are becoming null.
For example, I get Values from Activity A to Activity B (some id and image id etc) Now, I sent that values to Activity C as Intent extras. Here in Activity C, I get the values (Initial Case)! Now when I press back to Activity B and Again moved to Activity C, I am not getting the values(some id and image id etc) in Activity C. This Happens in Marshmallow only. In Activity C name is getting from Server in Activity B and is Moved accordingly! This is working perfectly till lollipop! But this happens in Marshmallow!

Yeah!! That was a silly mistake! In developer option, there was an option to remove activity data when moving to activities! It was ON somehow! Keep it OFF!

You should setAdapter such as;
mListOfProfiles.setAdapter(
new CustomProfileAdapter(this,mArrayListOfRegistrations));
Without setting adapter you cannot inflate you list.
If your data set on the ListView properly then please use the switch case in the Onitemclick function of the ListView. Like below code:-
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int position, long id) {
switch (adapterView.getId())
{
case R.id.listOFSerachProfiles:
Intent intent = new Intent(ActivityListOfSearchIDProfiles.this, ActivityShowProfileDetails.class);
intent.putExtra("fname", mRegistration.getFname());
intent.putExtra("lname", mRegistration.getLname());
intent.putExtra("hjID", mRegistration.getData());
intent.putExtra("gender", mRegistration.getGender());
intent.putExtra("dob", mRegistration.getDob());
intent.putExtra("tob", mRegistration.getTob());
intent.putExtra("age", mRegistration.getAge());
intent.putExtra("height", mRegistration.getHeight());
intent.putExtra("complexion", mRegistration.getComplexion());
intent.putExtra("blood_group", mRegistration.getBlood_group());
intent.putExtra("spect", mRegistration.getSpect());
intent.putExtra("ph_dis", mRegistration.getPh_dis());
intent.putExtra("nri", mRegistration.getNri());
intent.putExtra("caste", mRegistration.getCast());
intent.putExtra("rashi", mRegistration.getRashi());
intent.putExtra("hob", mRegistration.getHob());
intent.putExtra("city", mRegistration.getCity());
intent.putExtra("state", mRegistration.getState());
intent.putExtra("edu", mRegistration.getEdu());
intent.putExtra("occupation", mRegistration.getOcc());
intent.putExtra("place_occupation", mRegistration.getPlace_occ());
intent.putExtra("income", mRegistration.getIncome());
intent.putExtra("cat", mRegistration.getCat());
intent.putExtra("father", mRegistration.getFather());
intent.putExtra("mother", mRegistration.getMother());
intent.putExtra("father_name", mRegistration.getFather_name());
intent.putExtra("mother_name", mRegistration.getMother_name());
intent.putExtra("mama_name", mRegistration.getMama_name());
intent.putExtra("mama_place", mRegistration.getMama_place());
intent.putExtra("rel_name", mRegistration.getRel_name());
intent.putExtra("native_place", mRegistration.getNative_place());
intent.putExtra("no_brothers", mRegistration.getNo_brothers());
intent.putExtra("no_mar_bro", mRegistration.getNo_sisters());
intent.putExtra("no_sisters", mRegistration.getNo_mar_bro());
intent.putExtra("no_mar_sis", mRegistration.getNo_mar_sis());
intent.putExtra("parent_occ", mRegistration.getParent_occ());
intent.putExtra("family_property", mRegistration.getFamily_prop());
intent.putExtra("expect", mRegistration.getExpectations());
intent.putExtra("photo", mRegistration.getPhoto());

Hope this code help you :-)
Its better to extends ListActivity to ActivityListOfSearchIDProfiles. Then create ArrayAdapter or your custom listAdapter and add your data list to adapter. Then set Adapter to your listview.
I'm building an App that receives all wifi networks arround my house.
All wifi networks are being listed inside a Listview.
Now I would like to open a new activity when some listview item is clicked. But before that I would like to get the SSID from the selected Item.
I'm using onItemClick to get the position from the item and is working fine. The problem that I'm getting is that when I click at some item, I get a different SSID from the current selected item, the values are being desplayed like that:
WIFI 1 - When I click here I get the SSID from WIFI 3
WIFI 2 - When I click here I get the SSID from WIFI 2
WIFI 3 - When I click here I get the SSID from WIFI 1
Instead of getting the SSID from the wifi 1 when I click at wifi one and etc.
Can you guys check what am I doing wrong?

LinkedHashMap<String, String> item = new LinkedHashMap<String, String>();
String BSSID = results.get(size).BSSID;
int frequency = results.get(size).frequency;
if(!results.get(size).SSID.equals("FET")) {
item.put(ITEM_KEY, results.get(size).SSID.concat(""));
arraylist.add(item);

Reverse the order in which you add your list items to arraylist
try
{
size = 0;
...
while (size < results.size())
{
...
arraylist.add(item);
...
size++;
...
}
}
I am new to android programming.I am developing an app in which when user clicks on any ListView item it should go to Google maps app and display pin for that address on the map. But when I click on any item nothing happens.
Following is my display Activity.
public class DisplayActivity extends Activity implements OnItemClickListener{
ListView listView;
private String tag_name;
public List<NameAddress> nameAddressList;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_display);
listView = (ListView) findViewById(R.id.list);
Intent intent = getIntent();
if(intent!= null)
{
tag_name = intent.getStringExtra("DashItemName");
setTitle("List of " +tag_name+ " addresses");
}
nameAddressList = null;
try {
XMLDOMParserHandler parser = new XMLDOMParserHandler(tag_name);
nameAddressList = parser.parseXML(getAssets().open("data.xml"));
ArrayAdapter<NameAddress> adapter =
new ArrayAdapter<NameAddress>(this,R.layout.list_item, nameAddressList);
listView.setAdapter(adapter);
} catch (IOException e) {
e.printStackTrace();
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.display, menu);
return true;
}
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id)
{
// Build the intent
String address = nameAddressList.get(position).toString();
address = "geo:0,0?q=" + address;
String query = URLEncoder.encode(address, "utf-8");
Uri location = Uri.parse(query);
Intent mapIntent = new Intent(Intent.ACTION_VIEW, location;
mapIntent.setClassName("com.google.android.apps.maps", "com.google.android.maps.MapsActivity");
// Verify it resolves
PackageManager packageManager = getPackageManager();
List<ResolveInfo> activities = packageManager.queryIntentActivities(mapIntent, 0);
boolean isIntentSafe = activities.size() > 0;
// Start an activity if it's safe
if (isIntentSafe) {
startActivity(mapIntent);
}
else
{
Toast.makeText(this, "Please install google maps app", Toast.LENGTH_LONG).show();
}
}
}
Please suggest me a way to solve this problem.

It doesn't work for you because you forgot to assign listener to ListView:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_display);
listView = (ListView) findViewById(R.id.list);
listView.setOnItemClickListener(this);
...
}
Now, it will work for you.
You forgot to set the listener to your ListView.
Just after the creation of listView you should add:
listView.setOnItemClickListener(new OnItemClickListener(){
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
//your onItemClick code
}
}
