I suggest you use AutoCompleteTextView. An editable text view that shows completion suggestions automatically while the user is typing. The list of suggestions is displayed in a drop down menu from which the user can choose an item to replace the content of the edit box with.
The drop down can be dismissed at any time by pressing the back key or, if no item is selected in the drop down, by pressing the enter/dpad center key.
The list of suggestions is obtained from a data adapter and appears only after a given number of characters defined by the threshold.
Code Sample:
public class CountriesActivity extends Activity {
protected void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.countries);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
android.R.layout.simple_dropdown_item_1line, COUNTRIES);
AutoCompleteTextView textView = (AutoCompleteTextView)
findViewById(R.id.countries_list);
textView.setAdapter(adapter);
}
private static final String[] COUNTRIES = new String[] {
"Belgium", "France", "Italy", "Germany", "Spain"
};
}
You can refer to this example for a detailed explanation.
You can set a keyListener for your EditText
editText.setOnKeyListener(new View.OnKeyListener() {
#Override
public boolean onKey(View v, int keyCode, KeyEvent event) {
if(event.getAction() == KeyEvent.ACTION_DOWN && keycode == KeyEvent.KEYCODE_ENTER){
// do your search in here
String mobileno=mmobile.getText().toString();
//search it
boolean isInList = checkIsPhoneNumberInList(mRyotList,mobileno);
Log.i("CheckResult","is my phone number "+mobileno+" in mRyotList: "+isInList);
if(isInList){
Toast.makeText(getActivity(),"your phone number is already registered",Toast.Toast.LENGTH_LONG).show();
}
}
return false;
}
});
for check whether phone which you input in your edittext is in your database by this method
private boolean checkIsPhoneNumberInList(List<RyotMasterDb> mRyotList,String phoneNumber){
if (mRyotList == null || phoneNumber == null) {
return false;
}
boolean isIn = false;
for (RyotMasterDb rm: mRyotList) {
if (phoneNumber.equals(rm.getMobile_1())||phoneNumber.equals(rm.getMobile_2())){
isIn = true;
}
}
return isIn;
}

I have set switch box in adapter when switch box is enable then open custom check box list item. I have select check box item multiple. This switch box design when select spinner item and then open fragment page. When select multiple check box item and send JSON param like this:
"attendees": [
{
"id": "1",
"person": "xza"
},
{
"id": "2",
"person": "cfd"
}
]
And send button applying in activity. Spinner and save button design in activity and select item design in fragment.

JsonObject obj = new JsonObject();
obj.addProperty("id", attendee.getId());
obj.addProperty("name", attendee.getName());
jsonArray.add(obj);
}

I expect the output is:
"attendees":[{"id":"1","person":"fff"},{"id":"2","person":"dfdf"}]
But the actual output is:
"attendees": []

I am making a polling app where user can create a poll which is then stored in the firebase database and retrieved into listview of the app
when the user clicks on the list view he is directed to the the activity where there are number of progressbars
i have added a ON-click listener o the progress bar, So when user clicks on the progressbar the val of that option gets incremented in the database. so when a different user vote on the same poll the value from the database is fetched and value of the current user is added displaying the winner,but problem is the value of the progressbar1 gets the value from the database but the other two keep progress bar values start from 0 every time user clicks on the other two progress bar (ie 2 and 3).
please help

I will try to be brief and precise:
I have a user object that contains a chat, and this is updated every time I receive a message:
public class Usuarios implements Serializable {
private static final long serialVersionUID = 1113799434508676095L;
private int id;
private String nombre;
private String ip;
private boolean isSInicial;
//HERE WILL GO THE VARIABLE THAT STORMS THE CHAT, BUT I DO NOT KNOW HOW TO IMPLEMENT IT
public Usuarios(int id, String nombre, String ip, boolean isSInicial){
this.id = id;
this.nombre = nombre;
this.ip = ip;
this.isSInicial = isSInicial;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getNombre() {
return nombre;
}
public void setNombre(String nombre) {
this.nombre = nombre;
}
public String getIp() {
return ip;
}
public void setIp(String ip) {
this.ip = ip;
}
public boolean isSInicial() {
return isSInicial;
}
public void setSInicial(boolean SInicial) {
isSInicial = SInicial;
}}
I have an activity, that by clicking on a list, loads a new activity for the specific user:
listview.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int pos, long id) {
Usuarios e = (Usuarios) listview.getItemAtPosition(pos);
Intent visorDetalles = new Intent(view.getContext(),Chat.class);
if(Contactos.listaDeContactos.indexOf(e) >= 0) {
visorDetalles.putExtra("indice", Contactos.listaDeContactos.indexOf(e));
startActivity(visorDetalles);
}
else{
Toast.makeText(contexto,"Usuario fuera de linea",Toast.LENGTH_LONG);
}
}
});
I need the EditText that contains the Intent to be updated automatically every time I click on a user of a ListView.
I do not know what kind of variable I should use in the user object and how to implement it.
In your Usuarios class add the variable:
public ArrayList<String> currentChat;
Instead of passing the index, pass the Object himself maybe.
if(Contactos.listaDeContactos.indexOf(e) >= 0) {
visorDetalles.putExtra("usuario",e);
startActivity(visorDetalles);
}
else{
Toast.makeText(contexto,"Usuario fuera de linea",Toast.LENGTH_LONG);
}
And in your onCreate Chat Activity
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_chat);
Intent intent = getIntent();
Usuario usuario = (Usuario) intent.getSerializableExtra("usuario");
EditText myEditText = (EditText)findViewById(R.id.myEditText1));
String allChat;
for(String chatLine : usuario.currentChat) {
allChat += chatLine + '\n';
}
myEditText.setText(allChat);
Did I got your problem right ?
I am trying to push an Object of a class to Firebase by defining the function in that class itself, but I am getting stackOverflow error. I am using native datatypes in the class and a Firebase reference object.
The database structure I am using is as follows:
I have created Model Class for Orders as follows:
public class Orders {
private String billNo;
private String custId;
private String dateAndTime;
private int personCount;
private int status;
private int table;
private String orderId;
private boolean AC=true;
public String getBillNo() {
return billNo;
}
public void setBillNo(String billNo) {
this.billNo = billNo;
}
public String getCustId() {
return custId;
}
public void setCustId(String custId) {
this.custId = custId;
}
public String getDateAndTime() {
return dateAndTime;
}
public void setDateAndTime(String dateAndTime) {
this.dateAndTime = dateAndTime;
}
public int getPersonCount() {
return personCount;
}
public void setPersonCount(int personCount) {
this.personCount = personCount;
}
public int getStatus() {
return status;
}
public void setStatus(int status) {
this.status = status;
}
public int getTable() {
return table;
}
public void setTable(int table) {
this.table = table;
}
public String getOrderId() {
return orderId;
}
public void setOrderId(String orderId) {
this.orderId = orderId;
}
private DatabaseReference mDatabase = FirebaseDatabase.getInstance().getReference();
public Orders(String orderId, String billNum, String customerId, String date, int personCnt, int status, int tableNo, boolean AC){
this.billNo = billNum;
this.custId = customerId;
this.dateAndTime = date;
this.personCount = personCnt;
this.status = status;
this.table = tableNo;
this.orderId= orderId;
Log.v("Orders","I am in Orders");
}
public Orders(){
}
public void pushOrder(){
Log.v("PushOrdersId",this.getOrderId());
String OId = this.getOrderId();
mDatabase.child("Orders").child(OId).setValue(Orders.this);
}
}
Then I have created its child class Items as follows:
public class Items extends Orders {
private String itemId;
private int qty;
DatabaseReference mRef = FirebaseDatabase.getInstance().getReference("Orders");
public Items(String orderId, String billNum, String customerId, String date, int personCnt, int status, int tableNo, boolean AC) {
super(orderId, billNum, customerId, date, personCnt, status, tableNo, AC);
// this.itemId = itemId;
// this.qty = qty;
Log.v("Items","I am in Items child");
}
public Items() {
}
public String getItemId() {
return itemId;
}
public void setItemId(String itemId) {
this.itemId = itemId;
}
public int getQty() {
return qty;
}
public void setQty(int qty) {
this.qty = qty;
}
// public void push(HashMap<String, Items> items){
// for (Items item: items.values()) {
// String itemKey = mRef.child(this.getOrderId()).child("items").push().getKey();
//
// mRef.child(this.getOrderId()).child("items").child(itemKey).setValue(item);
// }
// }
}
And then I am calling a function PushOrders from Class Orders in another class:
nm=name.getText().toString();
mob=mobile.getText().toString();
seat=seats.getText().toString();
email=emailID.getText().toString();
mDatabase = FirebaseDatabase.getInstance().getReference("Orders");
String orderTd = mDatabase.push().getKey();
custId = id;
itemsHashMap = new HashMap<>();
// itemsArrayMap.put("itemid","1");
// itemsArrayMap.put("quantity","2");
dateAndTime = new Date();
personCount=Integer.parseInt(seat);
//Toast.makeText(getApplicationContext(), orderTd, Toast.LENGTH_LONG).show();
Items item = new Items(orderTd,billNo, custId, dateAndTime.toString(), personCount, status, table, AC);
item.pushOrder();
// item.push(itemsHashMap);
}
I was able to figure out the following line in class Orders is giving the error, but couldn't figure out why? and how to resolve it.
mDatabase.child("Orders").child(OId).setValue(Orders.this);
Error log

Can anyone please help me out in this case?
I have made some changes in your code according to your firebase DB Structure,
//Set order data
Orders orders=new Orders();
orders.setBillNo("123");
orders.setCustId("12");
orders.setDateAndTime(new Date().toString());
orders.setPersonCount(13);
orders.setStatus(2);
orders.setTable(2);
orders.setOrderId("23");
orders.setAC(true);
//Add items to order
List<Items> itemsList=new ArrayList<Items>();
for(int i=0;i<2;i++){
Items items=new Items();
items.setItemId("55");
items.setQty(i);
itemsList.add(items);
}
orders.setItems(itemsList);
DatabaseReference mRef = FirebaseDatabase.getInstance().getReference("Orders");
mRef.push().setValue(orders);
Your Order class
public class Orders {
private String billNo;
private String custId;
private String dateAndTime;
private int personCount;
private int status;
private int table;
private String orderId;
private boolean AC = true;
private List<Items> items;
//Generate getter and setters other code
}
Item Class
public class Items {
private String itemId;
private int qty;
//Generate getter and setters other code
}
You can fetch order using order key with complete items (You will get complete item list inside your order)
DatabaseReference mRef = FirebaseDatabase.getInstance().getReference("Orders").child(yourOrderKey);
mRef.addValueEventListener(new ValueEventListener() {
#Override
public void onDataChange(DataSnapshot dataSnapshot) {
for (DataSnapshot postSnapshot:dataSnapshot.getChildren()) {
Orders orders=postSnapshot.getValue(Orders.class);
}
}
#Override
public void onCancelled(DatabaseError databaseError) {
}
});
After creating an Instance of Firebase DB you just have to write the code snippet below:
User users = new User(userID, name, edtEmail.getText().toString().trim(), edtContactNumber.getText().toString().trim());
//saving data onto database
mDatabase.child("user").child(userID).setValue(users);
You can change the model and data as per requirement
Hello I'm new at Android. I want to populate a Spinner with a list of objects. I have googled how to do it but I just find examples with an array of strings.
Can any one help me?
This is my code:
Categories class:
public class Categories
{
#com.google.gson.annotations.SerializedName("id")
private String mId;
#com.google.gson.annotations.SerializedName("name")
private String mName;
public Categories()
{}
public Categories(String id, String name)
{
this.setId(id);
this.setName(name);
}
#Override
public String toString()
{
return mName;
}
// ******** GET *************
public String getId()
{
return mId;
}
public String getName()
{
return mName;
}
// ******** SET *************
public final void setId(String id)
{
mId = id;
}
public final void setName(String name)
{
mName = name;
}
}
This is my Activity code:
public class AgregarActividadActivity extends ActionBarActivity
{
private MobileServiceClient mClient;
private MobileServiceTable<Activities> mActivitiesTable;
private MobileServiceTable<Categories> mCategoriesTable;
private MobileServiceTable<Projects> mProjectsTable;
private EditText mTxtTitulo;
private EditText mTxtDescr;
String categryId = null;
List<Categories> catList = new ArrayList<Categories>();
Spinner spEstado;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.fragment_agregar_actividad);
try
{
mClient = new MobileServiceClient(
"https://site.azure-mobile.net/",
"AppKey",
this);
mActivitiesTable = mClient.getTable(Activities.class);
mCategoriesTable = mClient.getTable(Categories.class);
}
catch (MalformedURLException e)
{
createAndShowDialogExc(new Exception("There was an error creating the Mobile Service. Verify the URL"), "Error");
}
mTxtTitulo = (EditText) findViewById(R.id.txtTitulo);
mTxtDescr = (EditText) findViewById(R.id.txtDescripcion);
getCategories();
spEstado = (Spinner)this.findViewById(R.id.spEstado);
ArrayAdapter<Categories> Adapter = new ArrayAdapter<Categories>(this,
android.R.layout.simple_spinner_item, catList);
Adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spEstado.setAdapter(Adapter);
spEstado.setOnItemSelectedListener(
new AdapterView.OnItemSelectedListener() {
public void onItemSelected(
AdapterView<?> parent,
View view,
int position,
long id) {
Categories item = (Categories) parent.getItemAtPosition(position);
}
public void onNothingSelected(AdapterView<?> parent) {
}
}
);
spProjects = (Spinner)this.findViewById(R.id.spProyecto);
ArrayAdapter<Projects> proAdapter = new ArrayAdapter<Projects>(this,
android.R.layout.simple_spinner_item, proList);
proAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spProjects.setAdapter(proAdapter);
}
private void getCategories()
{
mCategoriesTable.execute(new TableQueryCallback<Categories>()
{
public void onCompleted(List<Categories> result, int count, Exception exception, ServiceFilterResponse response)
{
if (exception == null)
{
for (Categories item : result)
{
catList.add(item);
}
}
else
{
createAndShowDialog(exception, "Error");
}
}
});
}
}
I get the dropdownlist with the objects, but when I select one item, it is not displayed as the selected item, when the dropdownlist is hidden.
Any idea will help me! Thank you!!
You need to write a CustomAdapter for this. It is similar to writing a CustomAdapter for a ListView. You can look at Custom Adapter for List View for an idea
