Spinner value is not captured

Please, do not mark this as duplicate if you are not sure
I have three spinners and a botton. When the botton is clicked, the program makes a calculation depending on the value of the three spinners. Then this value passes two another activity and it shows in an editText. Here is my code:
Main
public class Main2Activity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main2);
capturarTexto();
}
private void capturarTexto() {
Button button_calc = (Button) findViewById(R.id.button_calc);
button_calc.setOnClickListener(get_edit_view_button_listener);
}
private Button.OnClickListener get_edit_view_button_listener = new Button.OnClickListener() {
public void onClick(View v) {
EditText edit_text = (EditText) findViewById(R.id.textBox1);
String edit_text_value = edit_text.getText().toString();
StringTokenizer st = new StringTokenizer(edit_text_value);
int num_words = st.countTokens();
Spinner espec = (Spinner) findViewById(R.id.espec);
String espec_value = espec.getSelectedItem().toString();
Spinner lengor = (Spinner) findViewById(R.id.lista_origen);
String lengor_value = lengor.getSelectedItem().toString();
Spinner lengdest = (Spinner) findViewById(R.id.lista_destino);
String lengdest_value = lengdest.getSelectedItem().toString();
double precio = 0;
if(espec_value .equals("Medicina")){
if (lengor_value .equals("ES") && lengdest_value .equals("EN")){
precio = num_words * 0.12;
}
if (lengor_value .equals("ES") && lengdest_value .equals("FR")){
precio = num_words * 0.12;
}
if (lengor_value .equals("ES") && lengdest_value .equals("DE")){
precio = num_words * 0.12;
}
Intent intent = new Intent(Main2Activity.this, Main3Activity.class);
intent.putExtra("precio",precio);
startActivity(intent);
}
};
}
Main2
public class Main3Activity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main3);
Intent intent=getIntent();
int precio =(int) intent.getExtras().getInt("precio");
TextView txtCambio = (TextView) findViewById(R.id.textView4);
txtCambio.setText("Precio Total: "+ precio + " €");
}
After testing it, the value passed in this line of code:
intent.putExtra("precio",precio)
is allways 0. But if I change it to this:
intent.putExtra("precio",num_words)
it passes correctly the total number of words. This makes me think that the script is not entering in the first if(espec_value .equals("Medicina")) and then, it is not making any calculation.
Does anyone have an idea of how to solve this problem?
Thank you for your time

You are sending Double value and accessing Integer value.
Change the line in Main3Activity.
double precio = intent.getExtras().getDouble("precio");
If you want to parse double value to int then add one more line
int p = (int) precio;

EditText.getText has a delay

I have this code:
void sendMessage(){
EditText messageText = (EditText) findViewById(R.id.editText3);
String messageString = messageText.getText().toString();
LinearLayout chatLayout = (LinearLayout) findViewById(R.id.chatView);
TextView chatMessage = new TextView(this);
chatMessage.setText(messageString);
chatLayout.addView(chatMessage);
messageText.setText("");
scrollChatDown();
/*
int arraySize = messages.size();
messages.set(arraySize + 1, chatMessage);
*/
}
When I call the function sendMessage(); by a button, it gives an empty TextView, when I call the function again, it gives me a TextView with the text.
Output
I did what jiotman said but it didn't work, now I have this
void sendMessage(){
TextView chatMessage = new TextView(this);
EditText messageText = (EditText) findViewById(R.id.editText3);
String messageString = messageText.getText().toString();
LinearLayout chatLayout = (LinearLayout) findViewById(R.id.chatView);
chatLayout.addView(chatMessage);
chatMessage.setText(messageString);
messageText.setText("");
scrollChatDown();
/*
int arraySize = messages.size();
messages.set(arraySize + 1, chatMessage);
*/
}

As I see, you`r trying to implement kind of list with item population.
I`d use bubble list view for this purpose, here is a simple tutorials how to do it.

Android Studio How to print on screen a variable content (number)

private EditText InputWiek; //First input
private EditText InputTspocz; //Second input
private TextView textout;
float Wiek = InputWiek;
float Tspocz = InputTspocz;
int Tmax = 220-Wiek;
int RT = Tmax-Tspocz;
int Tburn = 70*RT/100+Tspocz;
public void buttonOnClick(View v) {
Button button=(Button) v;
InputWiek = (EditText) findViewById(R.id.idWiek);
InputTspocz = (EditText) findViewById(R.id.idTspocz)
textout = (TextView) findViewById(R.id.txtOutput;
textout.setText(Tburn.getText())); //A little scrap here :/
}
}

you can use String.valeuOf(Tburn)

Saving information in EditText in android

I am trying to retain the data in my Edittext views, using onsaveinstancestate. The user clicks on the "add" button, which is supposed to retain the information in the Edittext views. When the add button is clicked, the user is taken back to activity main. When the module is selected for editing, the edit_module layout is shown but without the information in the edittext views, which I am trying to retain. Any ideas?? I think I may be missing a step, is there more to it than saving the strings in the onsaveinstancestate method, and then assigning those strings to the Edittext views when the activity is called?? New to Android.

try like this:
//intialization of shared preferences
private SharedPreferences preferences;
//in oncreate() give like this:
preferences = PreferenceManager.getDefaultSharedPreferences(this);
// store the edittext value in shared preferences
Editor edit = preferences.edit();
edit.putString("edittextvalue", edittextvalue);
edit.commit();
//whereever u want to get value and use
String apptext = preferences.getString("edittextvalue","");

use SharedPreferences to save edittext value

cannot be resolved or is not a field with some EditTexts

Ok so i have the following situation : I create some Editexts dynamically and i want to add another row of Editexts when one of the EditTexts from the last row is clicked.
I tried doing it the following way :
When the last row of EditTexts is created,i assign each of them an id
et.setId(997);
et.setId(998);
et.setId(999);
I declared each of them ;
public EditText camp1;
public EditText camp2;
public EditText camp3;
camp1 = (EditText) findViewById(997);
camp2 = (EditText) findViewById(998);
camp3 = (EditText) findViewById(999);
camp1.setOnClickListener(this);
camp2.setOnClickListener(this);
camp3.setOnClickListener(this);
And when i try to do this
case R.id.camp1:
inside a switch i get "camp1 cannot be resolved or is not a field"
What am i doing wrong ?
Is there a better way to detect when the last Edittext is clicked and create a new one ?

All you care about is the last editText, right? Just give the last editText an onClickListener that creates another editText. Then give the new editText the onClickListener and remove it from the the previous "last one".
like this:
camp1 = (EditText) findViewById(997);
camp2 = (EditText) findViewById(998);
camp3 = (EditText) findViewById(999);
camp1.setOnClickListener(this);
camp2.setOnClickListener(this);
camp3.setOnClickListener(new myListener());
...
//put this private class in the same activity as the stuff above
private class myListener implements View.OnClickListener {
#Override
public void onClick(View view) {
EditText editText = new EditText(YourActivityName.this);
editText.setOnClickListener(new myListener());
//TODO put it in your viewGroup
//Give the old EditText your standard onClickListener
view.setOnClickListener(YourActivityName.this);
//To change body of implemented methods use File | Settings | File Templates.
}
}

setId() does not add any variables to the R.id class because setId() executes at run-time, but R is generated at compile-time. Since you are creating dynamic views, you need to rethink your onClick() method. You might want to consider using a ListView to help you. You can also set up the three TextViews using a separate XML file, such as row.xml.
