I want to develop mylocation class and getlocation method so its returns lat loan.
How to access that in any class and get lat lon ??
may you need to create servics, that implement google locationAPI , Location listner more..
In that override method onLocationChanged you get lat-long now you can send that direct to your server or other class
i hope My answer is help you.
if don't then ask me again.
thank you.

here i need onitemclick with blockslug please any one can help, am new to android so i need some example.when on click i want take blockslug and load another method with that blockslug,like will get data from u "http://example.com/block/"+blockslug
i want to get blockslug from selected block
i hope guys i will get help
and sorry for my bad English,
First of all, you need to implement setOnItemSelectedListener. Refer to this https://stackoverflow.com/a/20151596/9346054
Once you selected the item, you can call them by making a new method. Example like below
public void onItemSelected(AdapterView<?> parent, View view, int pos,long id) {
Toast.makeText(parent.getContext(),
"OnItemSelectedListener : " + parent.getItemAtPosition(pos).toString(),
Toast.LENGTH_SHORT).show();
final String itemSelected = parent.getItemAtPosition(pos).toString();
showBlockSlug(itemSelected);
}
And then, at the method showBlockSlug() , you can call Retrofit.
private void showBlockSlug(final String blockslug){
final String url = "http://example.com/block/"+ blockslug;
//Do your stuff...
}
Goodmorning,
I've tried to implement the method that request permission first and than execute something but without success ...
Here is my MainActivity code:

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
String appLanguage = "ita";
LanguageUtil.setAppLanguage(getApplicationContext(), appLanguage);
/* .... other code.... */
sharedPreferences = this.getSharedPreferences("appname", MODE_PRIVATE);
mEditor = sharedPreferences.edit(); // set edit sharedpreferences
richiamaPermessi(); //permission request
requestLocationUpdates(); // function requestlocationupdates();
CaricamentoInizialeApplicazione(); // function for presetting configurations
}

}
}, getMainLooper());
} else richiamaPermessi();
}
/* Function for requesting access */
public void richiamaPermessi()
{
Permissions.check(this, new String[] { Manifest.permission.ACCESS_COARSE_LOCATION,
Manifest.permission.ACCESS_FINE_LOCATION},
"Permessi di locazione obbligatori per determinare la propria posizione!",
new Permissions.Options().setSettingsDialogTitle("Avviso").setRationaleDialogTitle("Permessi locazione"),

requestLocationUpdates();
}
#Override
public void onDenied(Context context, ArrayList<String> deniedPermissions) {
super.onDenied(context, deniedPermissions);
richiamaPermessi();
}
});
}
}
The problem is executing function ApiMarkers.getMarkers(.... with latitude and longitude filled ...) but can't execute because latitude and longitude are not loaded... I spent two nights without solution :(
Thanks for any help!
Cristian
long story short, I have one settlementItemeBase class as my father and two children. I want to make the father class parcelable so as extension happens, my two child classes be parcelable as well. I don't exactly know what I'm doing right or wrong. I searched little bit but nothing helped me.
here are my classes:
SettlementItemBase:
public class SettlementItemBase implements Parcelable{
public SettlementItemBase(){}
protected SettlementItemBase(Parcel in) {
}
public static final Creator<SettlementItemBase> CREATOR = new Creator<SettlementItemBase>() {
#Override
public SettlementItemBase createFromParcel(Parcel in) {
return new SettlementItemBase(in);
}
#Override
public SettlementItemBase[] newArray(int size) {
return new SettlementItemBase[size];
}
};
#Override
public int describeContents() {
return 0;
}
#Override
public void writeToParcel(Parcel dest, int flags) {
}
}
first child class:
public class FirstClass extends SettlementItemBase {
private int id;
private int cardId;
private String cardNumber;
private String expDate;
private String currency;
private String url;
public FirstClass(){
id = 0;
cardId = 0;
cardNumber = "";
expDate = "";
currency = "";
url = "";
}
protected FirstClass(Parcel in) {
super(in);
id = in.readInt();
cardId = in.readInt();
cardNumber = in.readString();
expDate = in.readString();
currency = in.readString();
url = in.readString();
}
#Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeInt(id);
dest.writeInt(cardId);
dest.writeString(cardNumber);
dest.writeString(expDate);
dest.writeString(currency);
dest.writeString(url);
}
public int getId() {
return id;
}
public int getCardId() {
return cardId;
}
public String getCardNumber() {
return cardNumber;
}
public String getExpDate() {
return expDate;
}
public String getCurrency() {
return currency;
}
public String getUrl() {
return url;
}
}
second child class:
public class SecondClass extends SettlementItemBase{
private int id;
private String currency;
private String accountNumber;
private String ibanNumber;
public SecondClass(int id, String currency,
String accountNumber, String ibanNumber){
this.id = id;
this.currency = currency;
this.accountNumber = accountNumber;
this.ibanNumber = ibanNumber;
}
protected SecondClass(Parcel in){
super(in);
id = in.readInt();
currency = in.readString();
accountNumber = in.readString();
ibanNumber = in.readString();
}
#Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeInt(id);
dest.writeString(currency);
dest.writeString(accountNumber);
dest.writeString(ibanNumber);
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getCurrency() {
return currency;
}
public String getAccountNumber() {
return accountNumber;
}
public String getIbanNumber() {
return ibanNumber;
}
}
I'm passing and getting an ArrayList of both child class' items with intent putParcelableArrayListExtra and getParcelableArrayListExtra methods and get the following error:
Parcel android.os.Parcel#2d0fde33: Unmarshalling unknown type code 3276849 at offset 172
any help would be appreciated 3>
well I'm posting this for those who may run into the same problem as me.
the problem was solved after adding the Creator statement to the child classes.
for one of the child classes it would be like:
public static final Creator<FirstClass> CREATOR = new Creator<FirstClass>() {
#Override
public FirstClass createFromParcel(Parcel in) {
return new FirstClass(in);
}
#Override
public FirstClass[] newArray(int size) {
return new FirstClass[size];
}
};
hope this helps. 3>
Activity1
private Cursor model = null;
private ClientAdapter adapter = null;
private ClientHelper helper = null;
private SharedPreferences prefs = null;
private ArrayAdapter<String> adapters;
private ArrayAdapter<String> adaptera;
private String[] available_locations;
private String[] selected_locations;
private ListView list1;
private ListView list2;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.locations);
list1 = (ListView) findViewById(R.id.available_locations);
list2 = (ListView) findViewById(R.id.selected_locations);
available_locations = getIntent().getStringExtra("List");
.....
Activity 2
....
public String getID(Cursor c) {
return (c.getString(0));
}
public String getclientName(Cursor c) {
return (c.getString(1));
}
public String getAddress(Cursor c) {
return (c.getString(2));
}
public String getTelephone(Cursor c) {
return (c.getString(3));
}
public String getCuisineType(Cursor c) {
return (c.getString(4));
}
public double getLatitude(Cursor c) {
return (c.getDouble(5));
}
public double getLongitude(Cursor c) {
return (c.getDouble(6));
}
public ArrayList<String> getclient;
getclient.add("clientName");
getclient.add("Address");
getclient.add("Telephone");
getclient.add("cuisineType");
getclient.add("lat");
getclient.add("lon");
public Intent intenti;
intenti = new Intent(ClientHelper.this, SetDestination.class);
intenti.putExtra("List", getclient);
startactivity(intenti);
How do I pass information from Activity2 to Activity1?
I want to do a Listview where I can select clients from the list that I have already added (hence two activity, list1 and list2, in activity1)
Use can use the Bundle to pass the data from one activity to other.
First make the object parcelable.You can do that using the plugin of Parcelable in android studio.
Example.
Intent intent=new Intent(getActivity(),targetclassname.class);
HomeScreenData homeScreenData=new HomeScreenData();//Pojo class
intent.putExtra("categorydesc",homeScreenData);
startActivity(intent);
{
//Pojo Class`enter code here`
public class HomeScreenData implements Parcelable {
private String imagePath;
private String imageTitle;
public String getImagePath() {
return imagePath;
}
public void setImagePath(String imagePath) {
this.imagePath = imagePath;
}
public String getImageTitle() {
return imageTitle;
}
public void setImageTitle(String imageTitle) {
this.imageTitle = imageTitle;
}
#Override
public int describeContents() {
return 0;
}
#Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeString(this.imagePath);
dest.writeString(this.imageTitle);
}
public HomeScreenData() {
}
protected HomeScreenData(Parcel in) {
this.imagePath = in.readString();
this.imageTitle = in.readString();
}
public static final Parcelable.Creator<HomeScreenData> CREATOR = new Parcelable.Creator<HomeScreenData>() {
public HomeScreenData createFromParcel(Parcel source) {
return new HomeScreenData(source);
}
public HomeScreenData[] newArray(int size) {
return new HomeScreenData[size];
}
};
}
