Android AutoCompleteTextView return wrong string

I have a little problem in my android app. I want to put a word in an AutoCompleteTextView and then jump to a specific Activity(depend on the word that the user gave).
The problem is that, when i give a specific word, the program does not correspond with the correct answer as expected but returns a wrong toast message. However with the log that i put i see the correct answer. I think that the solution is silly but i stuck and need to solve this.
the code:
Activity.java
public class paralActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_paral);
final String [] temp = {"one","two","three"};
AutoCompleteTextView actv = (AutoCompleteTextView) findViewById(R.id.autoCompleteTextView);
actv.clearListSelection();
final RelativeLayout myRelative = (RelativeLayout) findViewById(R.id.find);
myRelative.setVisibility(View.INVISIBLE);
ImageView myImage = (ImageView) findViewById(R.id.aktoploika);
myImage.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent = new Intent(paralActivity.this, topParalActivity.class);
startActivity(intent);
}
});
ImageView myOtherImage = (ImageView) findViewById(R.id.aeroporika);
myOtherImage.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
myRelative.setVisibility(View.VISIBLE);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(paralActivity.this, android.R.layout.select_dialog_item, temp);
//Getting the instance of AutoCompleteTextView
AutoCompleteTextView actv = (AutoCompleteTextView) findViewById(R.id.autoCompleteTextView);
actv.setThreshold(1);//will start working from first character
actv.setAdapter(adapter);//setting the adapter data into the AutoCompleteTextView
actv.setTextColor(Color.RED);
ImageView findBeach = (ImageView) findViewById(R.id.find_beach);
findBeach.setOnClickListener(new View.OnClickListener() {
#Override
** public void onClick(View view) {
AutoCompleteTextView actv = (AutoCompleteTextView) findViewById(R.id.autoCompleteTextView);
String choice = actv.getText().toString();
Log.i("Answer",choice);
if (choice == "one"){
Intent firstIntent = new Intent(paralActivity.this, nauagioActivity.class);
startActivity(firstIntent);
}else if (choice == temp[1]){
Intent secondIntent = new Intent(paralActivity.this, gerakasActivity.class);
startActivity(secondIntent);
}else if (choice == temp[2]){
Intent thirdIntent = new Intent(paralActivity.this, limnionasActivity.class);
startActivity(thirdIntent);
}else{
Toast.makeText(paralActivity.this,"wrong",Toast.LENGTH_SHORT).show();
}
}
});
}
});
}
}
To help u understand, in this activity a have 2 imageViews. When the user presses the second, a relativeLayout appears (with an AutoCompleteTextView and a button inside). After the user writes the word when presses the button it must go to the specific activity. I declared a String Array (temp[3]) with three words inside and 3 activities for each of the words.
The problem starts in the last onclick method that i put ** . Every time i put a correct word from the Array i take the Toast message but in the log i see the correct.
here is Activity.xml

Thanks a lot!

Try choice.equals("one") instead of choice == "one"

Cannot access resources in a layout in a PopupWindow, Objects are null referenced

I have an android application when clicked on an option from a side bar it goes to a fragment, and then into another fragment which has clickable radio buttons. When clicked on these it will create a popup window with some text fields in it.
Basically this is how the flow goes,
Activity --> Fragment 1 --> Fragment 2 --> PopupWindow
When i try to access the resources inside this popupWindow, in example:
damageComponenetAutoCompleteTextview = (AutoCompleteTextView) findViewById(R.id.popup_damage_component_item);
damageComponenetAutoCompleteTextview.requestFocus();
in the line damageComponenetAutoCompleteTextview.requestFocus(); it gives me an error,
Attempt to invoke virtual method on a null object reference
I believe it's due to a wrong view i'm referring when calling on the Resources. Hope someone could point me to what i'm doing wrong. Thanks in Advance.
This is the method i'm using to create the popupWindow.
public void showDamagedItemEntryPopup(RadioButton radioButton, View view){
LayoutInflater layoutInflater = (LayoutInflater)getBaseContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
ViewGroup viewG = ((ViewGroup)view.findViewById(R.id.damaged_comp_popup));
//I tried passing the root view to inflate() method instead of passing it null. Didn't work.
//View popupView = layoutInflater.inflate(R.layout.component_selection_popup, null);
View popupView = layoutInflater.inflate(R.layout.component_selection_popup, null);
final PopupWindow popupWindow = new PopupWindow(
popupView,
ViewGroup.LayoutParams.WRAP_CONTENT,
ViewGroup.LayoutParams.WRAP_CONTENT);
popupWindow.setAnimationStyle(R.style.popupAnimation);
//I tried setting the content view manually but didnt work
//popupWindow.setContentView(view.findViewById(R.id.damaged_comp_popup));
Button buttonClose = (Button)popupView.findViewById(R.id.close_add_component_btn);
// Close button damaged item popop window
buttonClose.setOnClickListener(new Button.OnClickListener(){
#Override
public void onClick(View v) {
popupWindow.dismiss();
}
});
originalAmount = (EditText)this.findViewById(R.id.popup_add_component_original_amount);
customerContribution = (EditText)this.findViewById(R.id.popup_percentage);
quantity = (EditText)this.findViewById(R.id.popup_quantity);
finalAmount = (EditText)this.findViewById(R.id.popup_add_component_final_amount);
remarks = (EditText)this.findViewById(R.id.popup_add_component_remarks);
// Item Spinner
itemSpinnerArray = new ArrayList<String>();
itemSpinnerArray.add("Select Item");
// Status Spinner
ArrayList<String> statusSpinnerArray = new ArrayList<String>();
statusSpinnerArray.add("MR");
statusSpinnerArray.add("DR");
statusSpinnerArray.add("SP");
// Error comes at this point initially. When these Resource access line codes are commented, the popup works fine.
damageComponenetAutoCompleteTextview = (AutoCompleteTextView) findViewById(R.id.popup_damage_component_item);
damageComponenetAutoCompleteTextview.requestFocus();
ArrayAdapter<String> itemSpinnerArrayAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_dropdown_item, itemSpinnerArray);
damageComponenetAutoCompleteTextview.setThreshold(1);
damageComponenetAutoCompleteTextview.setAdapter(itemSpinnerArrayAdapter);

//int index = cityNames.indexOf(actvCity.getText().toString());
itemSpinnerValue = (String) parent.getItemAtPosition(position);
Log.d("SK-->", "----------------------------------------------------------");
Log.d("SK-->","itemSpinnerValue: " + itemSpinnerValue);
}
});
statusSpinner = (Spinner)this.findViewById(R.id.popup_status_spinner);
ArrayAdapter<String> statusSpinnerArrayAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_dropdown_item, statusSpinnerArray);
statusSpinner.setAdapter(statusSpinnerArrayAdapter);
//Creating a text Watcher
TextWatcher textWatcher = new TextWatcher() {
#Override
public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {
}
#Override
public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {
}
#Override
public void afterTextChanged(Editable editable) {
//here, after we introduced something in the EditText we get the string from it
//String answerString = originalAmount.getText().toString();
if (originalAmount.getText().toString().trim().equals("") || customerContribution.getText().toString().trim().equals("")
|| quantity.getText().toString().trim().equals("")) {
// Error , one or more editText are empty
}
else
{
calculateFinalAmount();
}
//and now we make a Toast
//modify "yourActivity.this" with your activity name .this
//Toast.makeText(yourActivity.this,"The string from EditText is: "+answerString,0).show();
}
};
// Adding Text Watcher to our text boxes
originalAmount.addTextChangedListener(textWatcher);
customerContribution.addTextChangedListener(textWatcher);
quantity.addTextChangedListener(textWatcher);
// Show the popup
popupWindow.showAtLocation(view, Gravity.CENTER, 0, 0);
}
This is the XML i'm using for the popup.

It seems your damageComponenetAutoCompleteTextview belongs to the popupWindow which you inflated at top.
So try changing
damageComponenetAutoCompleteTextview = (AutoCompleteTextView) findViewById(R.id.popup_damage_component_item);
To
damageComponenetAutoCompleteTextview = (AutoCompleteTextView) popupView.findViewById(R.id.popup_damage_component_item);
And other relevant elements as well.

spinner unusable and misdisplayed

When I first launch my app everything displays and works correctly but when I close and reopen it a spinner and button that sit next to each other at the top of my relative layout are only about half of their usual height and the spinner is unusable. If I click it nothing drops down (but the button works as usual). Other elements below the spinner and but display as usual.
I spent half the day googling and playing with the app code and layout XML and have made little to no progress.
Anyone got a clue as to what could be causing this? It only happens on subsequent runs of the app.
Here is the layout XML:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

This should be the relevant parts of the main activity that call it:
public class MainActivity extends Activity {
static Spinner nameSpinner;
ArrayAdapter nameAdapter;
static ArrayList nameList;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
#Override
public void onResume() {
super.onResume();
// get spinner and init array if needed
if (nameList == null) {
nameSpinner = (Spinner) findViewById(R.id.namespinner);
nameList = new ArrayList();
nameList.add("( Add )");
}
// populate spinner
nameAdapter = new ArrayAdapter(this,
android.R.layout.simple_spinner_dropdown_item, nameList);
nameSpinner.setAdapter(nameAdapter);
// listen for events/selections on the spinner
nameSpinner.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView parentView,
View selectedItemView, int position, long id) {
// read state
}
}
#Override
public void onNothingSelected(AdapterView parentView) {
// do I want to do anything here?
}
});
}
}
Edited to clean up the code display and add the class def. and class variables.

You have to insert the code wrote in the onresume method in oncreate method!

Setting the spinner in an if statement that didn't really have anything to do with setting the spinner was the cause of the problem. By changing this:
if (nameList == null) {
nameSpinner = (Spinner) findViewById(R.id.namespinner);
nameList = new ArrayList();
nameList.add("( Add )");
}
to
nameSpinner = (Spinner) findViewById(R.id.namespinner);
if (nameList == null) {
nameList = new ArrayList();
nameList.add("( Add )");
}
got it sorted.
A good nights sleep and fresh eyes where all that were needed. :P

Show Edit text on spinner item selected

I have a Spinner in my class with certain items. I have to display an EditText whose visibility I have set to "Invisible". I need to show this EditText when "Others" item is selected in the spinner.
Here is my code:-
Activity class:-
protected void onCreate(Bundle savedInstanceState)
{
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.maintenance);
ETServiceStation = (EditText)findViewById(R.id.ETServiceStation);
ETServiceType = (EditText)findViewById(R.id.ETServiceType);
ETServiceCost= (EditText)findViewById(R.id.ETServiceCost);
spinServiceType = (Spinner)findViewById(R.id.spinServiceType);
btnMaintenenceSave= (ImageButton)findViewById(R.id.btnMaintenenceSave);
btnMaintenanceClear = (ImageButton)findViewById(R.id.btnMaintenenceClear);
spinServiceType.setOnItemSelectedListener(this);
btnMaintenanceClear.setOnClickListener(this);
btnMaintenenceSave.setOnClickListener(this);
ArrayAdapter<String> serviceTypeAdapter = new ArrayAdapter<String>(getApplicationContext(), R.array.service_type_array, android.R.layout.simple_spinner_item);
serviceTypeAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinServiceType.setAdapter(serviceTypeAdapter);
}
public void onItemSelected(AdapterView<?> parent, View view, int servicePos, long id)
{
// TODO Auto-generated method stub
spinnerServiceType = spinServiceType.getItemAtPosition(servicePos).toString();
if(spinnerServiceType.matches("Others"))
{
ETServiceType = (EditText)findViewById(R.id.ETServiceType);
ETServiceType.setVisibility(View.VISIBLE);
spinnerServiceType = ETServiceType.getText().toString();
}
serviceType = spinnerServiceType;
}
}

Database:
public long createMainEntry(MaintenanceExpense me)
{
ContentValues mcv = new ContentValues();
mcv.put(KEY_SERVICE_STATION,me.getServiceStation());
mcv.put(KEY_SERVICE_TYPE,me.getServiceType());
mcv.put(KEY_SERVICE_COST,me.getServiceCost());
return otherInfoDatabase.insert(MAINTENANCE_DATABASE_TABLE, null, mcv);
}
I have to display the ETServiceType when "Others" item is clicked.
Thanks for any help.

public void onItemSelected(AdapterView<?> parent, View view, int position, long id)
{
if(spinServiceType.getItemAtPosition(position).toString().equalsIgnorecase("Others")
{
editextObject.setVisibility(View.VISIBLE);
}
}

public void onItemSelected(AdapterView<?> parent, View view, int position, long id)
{
// TODO Auto-generated method stub
spinnerServiceType = spinServiceType.getItemAtPosition(position).toString();
//if spinnerServiceType 's value is other
//then set visibility of textview visible put text watcher on it so u can get text when user finished ..if u dont want then u can use simple getText then change its visibility
//As u are setting your array value from resource you cant update it programmatically
//so first of all u have to take its array items in list . so u can update this list after user enter the value in edit text

Spinner inside a PopUp Window

I've created a popup window and put a spinner inside it. But I can't get values when an item is selected from it.
My code to create popup:
LayoutInflater inflater = (LayoutInflater) this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
popwindow=new PopupWindow(inflater.inflate(R.layout.addpain, null,false),300,350,true);
popwindow.showAtLocation(this.findViewById(R.id.tabHost), Gravity.CENTER, 0, 0);
XML file of PopUp

My StatusUpload Function:
public void statusupload(View view)
{
EditText status=(EditText) popwindow.getContentView().findViewById(R.id.statustbox);
Spinner spinner=(Spinner) popwindow.getContentView().findViewById(R.id.spinner_list);
spinner.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position,long id)
{
category=parent.getSelectedItem().toString();
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
category="Miscellaneous";
}
});
Toast.makeText(getBaseContext(),category, Toast.LENGTH_LONG).show();
}
What happens is the vraible category isnt getting any values !! IT's just blank.

you're not seeing the results you want because everything hinges on the button to turn on your spinner listener. thus you have have to click the button, make a spinner selection, and then click the button again. I'd seriously reconsider the design. For instance, are you aware that you don't need the listener on to get the item selected? you could just use:
public void statusupload(View view)
{
EditText status=(EditText) popwindow.getContentView().findViewById(R.id.statustbox);
Spinner spinner=(Spinner) popwindow.getContentView().findViewById(R.id.spinner_list);
category = spinner.getSelectedItem().toString();
Toast.makeText(getBaseContext(),category, Toast.LENGTH_LONG).show();
}
