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 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

Getting NullPointerException when call get() methods from model class in Android

I have the following model class:
#SuppressWarnings("serial")
public class Cheltuiala implements Serializable {
private int id;
private Date data;
private String tip;
private float pret;
public Cheltuiala() {
}
public Cheltuiala(Date data, String tip, float pret) {
this.data = data;
this.tip = tip;
this.pret = pret;
}
public int getId() {
return id;
}
public Date getData() {
return data;
}
public String getTip() {
return tip;
}
public float getPret() {
return pret;
}
public void setId(int id) {
this.id = id;
}
public void setData(Date data) {
this.data = data;
}
public void setTip(String tip) {
this.tip = tip;
}
public void setPret(float pret){
this.pret = pret;
}
#Override
public String toString() {
return "id:" + id + " data:" + data + " tip:" + tip + " pret:" + pret;
}
}
Here is the method from the DetailsActivity that extends Activity:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_details); // legatura dintre activitate si view
Intent intent = getIntent(); //continutul cu care s-a apelat
final Cheltuiala cheltuiala = (Cheltuiala) intent.getSerializableExtra("cheltuiala");
System.out.println(cheltuiala.getData());
EditText data = (EditText) findViewById(R.id.editTextData);
data.setText(cheltuiala.getData().toString());
EditText tip = (EditText) findViewById(R.id.editTextTip);
System.out.println(cheltuiala);
tip.setText(cheltuiala.getTip());
EditText pret = (EditText) findViewById(R.id.editTextPret);
pret.setText(String.valueOf(cheltuiala.getPret()));
}
When I print 'cheltuiala', I see what I want, but when I call get() methods from 'Cheltuiala' class, I got NullPointerException. Does anyone know why ?

as you have use toString() method you can get NPE when getData is null. you can check getData that is null or not and if is not null use .toString()
you can use following code:
data.setText(cheltuiala.getData() == null ? "" : cheltuiala.getData().toString());
as you say when i use every get method that is null might be data is null. check that you have editTextData id in activity_details

Values are changed when inserted in Bundle

When I put an object into a bundle so I can transfer it to another Activity, changing the value of the attribute IdEscritorio occurs.
In my LoginActivity IdEscritorio the value of = 1, when I get in my Main Activity is it with the value of 7.

The problem is with your Parcelable class. In your writeToParcel class, you are writing only Id and Nome to the Parcel.
#Override
public void writeToParcel(Parcel out, int flags)
{
out.writeInt(getId());
out.writeString(getNome());
}
However, you are reading all 5 fields when creating the object in Usuario(Parcel parcel).
For this to work correctly, change your writeToParcel method to:
public void writeToParcel(Parcel out, int flags)
{
out.writeInt(getId());
out.writeInt(getIdEscritorio());
out.writeString(getNome());
out.writeString(getLogin());
out.writeString(getSenha());
}

How do I populate a spinner with a list of objects and not just strings?

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
