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

Can anyone help me with this?
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);
damageComponenetAutoCompleteTextview.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
//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.

Android there is some way for don't waste layout when orientation change?

I have an application that have a TableLayout with 60 texviews.
The user can touch them and a DialogActivity start for take the text and background color of the clicked TextView.
But the app have a bug that some times all TextView take the color of the first inputed color and inside of the code i haven't a loop that assign the color.
I think that, the problem come from to the orientation of the screen (possible?).
Because the Activity that contain TableLayout is landscape and the Dialog is portrait.
Infact when the Dialog start behind it there is the Activity that change his orientation with the Dialog and all textviews change their color.
How can i avoid this bug?
Why this happend?
Acitivity landscape:
public class ActivitySetOrario extends ActionBarActivity {
//Static perch� cosi non perdo i dati inseriti in precedenza!
static int clickedTextViewId; // Declare TextView as class level member field
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_set_orario);
MySQLiteHelper db = new MySQLiteHelper(this);
//Get all materie inside database
List<Materia> materia = db.getAllMaterie();
//change all TextView inputed from user
if(materia.isEmpty()){
//do nothing
}else {
for (Materia mat : materia) {
//Change all the TextView with values stored inside the database
TextView changedtextview = (TextView) findViewById(mat.getID());
changedtextview.setText(mat.getMateria());
changedtextview.setBackgroundColor(mat.getColor());
}
}
}//Fine oncreate
//Prende indietro la materia aggiunta dall'ActivityAddMateria
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if(requestCode == 1) {
if (resultCode == RESULT_OK) {
MySQLiteHelper db = new MySQLiteHelper(this);
String result = data.getStringExtra("result"); //Take the materia from Dialog
int color = data.getIntExtra("color", 1); //Take the color from Dialog
//Here i need to recognize row and column
db.addMateria(new Materia(clickedTextViewId, result, color));
TextView clickedtextView = (TextView) findViewById(clickedTextViewId); //(TextView) view;
clickedtextView.setText(result);
clickedtextView.setBackgroundColor(color);
}
if (resultCode == RESULT_CANCELED) {
//Nessuna materia inserita
}
}
}//onActivityResult

You shouldn't be using the ids of the textviews in your database: they can change between different compilations of your app. Which could be the culprit. However, the only way they're all being set is in the for loop: you should verify your database is correct and verify that loop is not running every time.

Okay so you have two activities total right?
Here's the deal: Look at your image. Activity 1 starts activity 2 right? And you're expecting to get information from your activity 2 back to activity 1, correct? Alright.
First thing to learn:
startActivity(intent);
This method states that you will just initiate an activity but expect nothing back from it. So even if you want to send information back to activity 1 THROUGH activitiy 2 it will not work. Instead you must do this:
startActivityForResult(intent, 1);
The second parameter is an integer that can help you differentiate between different activity calls, it is not important for you right now.
Now, because you say "ForResult" in your method above, in your MainActivity now you must implement this:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
// here you will work with the code.
// data is your intent data sent from activity 2
// where you say this in your own code:
// Passing data as a parecelable object to MainActivity
// intent.putExtra("drug",drug);
}
Now the last thing to note:
In SecondElementActivity.java where you have this:
// Opening the activity
startActivity(intent);
It is wrong. You know why? because you're saying that you want to start a new activity. But in Android you already have a parent for this activity, which is activity 1. So your activity 1 called 2, when you end activity 2 it will go back to 1. So, replace that line for this:
setResult(RESULT_OK, intent);
finish();
EDIT:
Also I don't know if this is correct, I don't do it this way, so here is my fix:
OnClickListener listener = new OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent("com.example.SecondElementActivity");
startActivity(intent);
}
};
When you say you want to make a new intent you should pass two parameters:
Intent intent = new Intent(this, SecondElementActivity.class);
The second parameter is the name of the class you want to call.

You can try like this :
activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<ImageButton
android:id="#+id/addBtn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:src="#drawable/ic_launcher"
android:contentDescription="#string/hello_world"/>
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBottom="#+id/addBtn"
android:layout_centerHorizontal="true"
android:text="mainTxt"
android:textAppearance="?android:attr/textAppearanceLarge"
android:textSize="32sp" />
<!-- List -->
<ListView
android:id="#+id/myListView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_below="#+id/textView1"
android:layout_marginTop="20dp" />
</RelativeLayout>
Follow This tutorial for populating ListView just change adapter and row.xml from that tutorial
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"

Android Activity as dialog black border

I have activity as a dialogue, all the shows I like. But I have a problem with a frame around them. Just like here.
My Activity:
public class AlarmAlert extends Activity implements Alarms.AlarmSettings {
#Override
protected void onCreate(Bundle icicle) {
super.onCreate(icicle);
AlarmAlertWakeLock.acquire(this);
/*
* FIXME Intentionally verbose: always log this until we've fully

Intent i = getIntent();
mAlarmId = i.getIntExtra(Alarms.ID, -1);
Alarms.getAlarm(getContentResolver(), this, mAlarmId);
mKlaxon = new AlarmKlaxon();
mKlaxon.postPlay(this, mAlarmId);
/* Set the title from the passed in label */
setTitleFromIntent(i);
/*
* allow next alarm to trigger while this activity is active
*/
Alarms.disableSnoozeAlert(AlarmAlert.this);
Alarms.disableAlert(AlarmAlert.this, mAlarmId);
Alarms.setNextAlert(this);
mKlaxon.setKillerCallback(new AlarmKlaxon.KillerCallback() {
public void onKilled() {
if (Log.LOGV)
Log.v("onKilled()");
updateSilencedText();
/* don't allow snooze */
mSnoozeButton.setEnabled(false);
dismiss();
mState = KILLED;
}
});
updateLayout();

public void onShake() {
snooze();
if (mCaptchaSnooze == 0)
finish();
}
});
}
}
private void setTitleFromIntent(Intent i) {
mLabel = i.getStringExtra(Alarms.LABEL);
if (mLabel == null || mLabel.length() == 0) {
mLabel = getString(R.string.default_label);
}
setTitle(mLabel);
}

TextView silenced = (TextView) findViewById(R.id.silencedText);

How do I remove the border.

dialog.getWindow().setBackgroundDrawableResource(android.R.color.transparent);
Dialog

You have two options. You can set the theme of your Activity to
Theme_Translucent_NoTitleBar
Or you have to create a new theme and load it with a custom nine patch as specified here
