Mein EditText erscheint als null

Question

Ich habe an dieser App gearbeitet, die Informationen sammelt und dann in E-Mail-Form sendet. Alle meine anderen EditTexte arbeiten mit Ausnahme des ersten, Pilot (der Hinweis ist Name, wie im Namen des Piloten). Ich habe das mehrere Stunden lang gründlich durchgegangen, aber ich kann einfach nicht finden, was das Problem ist. Der einzige Grund, warum ich seine Null weiß, ist, weil, wenn es das E-Mail-Format geht in alle sagt, es ist null

public class InfoSheet extends AppCompatActivity { 
private double VesselUnits; 
private EditText pilot, ship, to, from, LOA, MBDTH, CUSD, zone1, zone2, CallSign; 
private Spinner agent_spinner; 
private Button btnSubmit; 
private String date, agent, Spilot, Sship, Sto, Sfrom, Szone1, Szone2, SCallSign, SVesselUnits; 
@Override 
protected void onCreate(Bundle savedInstanceState) { 

    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_info_sheet); 
    date=getTodaysDate(); 
    addListenerOnButton(); 
} 
public void collectNCalc(){ 
    //grab all of our info 
    agent_spinner = (Spinner) findViewById(R.id.agent_spinner); 
    btnSubmit = (Button) findViewById(R.id.btnSubmit); 
    pilot = (EditText) findViewById(R.id.Pilot); 
    ship = (EditText) findViewById(R.id.ship); 
    to = (EditText) findViewById(R.id.to); 
    from = (EditText) findViewById(R.id.from); 
    LOA = (EditText) findViewById(R.id.LOA); 
    MBDTH = (EditText) findViewById(R.id.MBDTH); 
    CUSD = (EditText) findViewById(R.id.CUSD); 
    zone1 = (EditText) findViewById(R.id.zone1); 
    zone2 = (EditText) findViewById(R.id.zone2); 
    CallSign = (EditText) findViewById(R.id.CallSign); 

    //convert what we need to int to do equations 
    String sLOA = LOA.getText().toString(); 
    double intLOA = Integer.valueOf(sLOA); 
    intLOA = intLOA*3.281; 

    String sMBDTH = MBDTH.getText().toString(); 
    double intMBDTH = Integer.valueOf(sMBDTH); 
    intMBDTH = intMBDTH*3.281; 

    String sCUSD = CUSD.getText().toString(); 
    double intCUSD = Integer.valueOf(sCUSD); 
    intCUSD = intCUSD*3.281; 

    VesselUnits = intLOA*intMBDTH*intCUSD; 
    VesselUnits = VesselUnits/10000; 
    Spilot=pilot.getText().toString(); 
    Sship=ship.getText().toString(); 
    Sto=to.getText().toString(); 
    Sfrom=from.getText().toString(); 
    Szone1=zone1.getText().toString(); 
    Szone2=zone2.getText().toString(); 
    SCallSign=CallSign.getText().toString(); 
    agent=agent_spinner.getSelectedItem().toString(); 
    //SVesselUnits=String.valueOf(VesselUnits); 
} 
public void addListenerOnButton() { 
    final Context context2 = this; 
    btnSubmit = (Button) findViewById(R.id.btnSubmit); 
    btnSubmit.setOnClickListener(new OnClickListener() { 

     @Override 
     public void onClick(View v) { 
      Intent i2 = new Intent(context2, DigitalSignature.class); 
      //do the Calc 
      collectNCalc(); 
      //pass to next activity 
      i2.putExtra("Pilot",Spilot); 
      i2.putExtra("ship",Sship); 
      i2.putExtra("to",Sto); 
      i2.putExtra("from",Sfrom); 
      i2.putExtra("zone1",Szone1); 
      i2.putExtra("zone2",Szone2); 
      i2.putExtra("callsign",SCallSign); 
      i2.putExtra("agent",agent); 
      i2.putExtra("vessleunits",VesselUnits); 
      i2.putExtra("date",date); 
      startActivity(i2); 
     } 

    }); 
} 

sein auf die nächste und letzte Aktivität gesendet:

public class DigitalSignature extends AppCompatActivity { 
String pilot, ship, to, from, zone1, zone2, CallSign, agent, date; 
Toolbar toolbar; 
Button btn_get_sign, mClear, mGetSign, mCancel, btn_send; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_digital_signature); 
    Bundle extras = getIntent().getExtras(); 
    if (extras != null) { 
     pilot = extras.getString("pilot"); 
     ship = extras.getString("ship"); 
     to = extras.getString("to"); 
     from = extras.getString("from"); 
     zone1 = extras.getString("zone1"); 
     zone2 = extras.getString("zone2"); 
     CallSign = extras.getString("callsign"); 
     agent = extras.getString("agent"); 
     vesselUnit = extras.getDouble("vesselunits"); 
     date = extras.getString("date"); 
    } 
btn_send.setOnClickListener(new OnClickListener() { 
     public void onClick(View v){ 
      Uri path = Uri.parse("file://" + file); 
      Intent emailIntent = new Intent(Intent.ACTION_SEND); 
      emailIntent.putExtra(Intent.EXTRA_TEXT, pilot+"\n"+ship+"\n"+to+"\n"+from+"\n"+zone1+"\n"+zone2+"\n"+CallSign+"\n"+agent+"\n"+vesselUnit); 
      // set the type to 'email' 
      emailIntent.setType("image/png"); 
      String to[] = {"metropilottickets@gmail.com"}; 
      emailIntent.putExtra(Intent.EXTRA_EMAIL, to); 
      // the attachment 
      emailIntent.putExtra(Intent.EXTRA_STREAM, path); 
      // the mail subject 
      emailIntent.putExtra(Intent.EXTRA_SUBJECT, pilot+"'s Ticket for "+ship); 
      startActivity(Intent.createChooser(emailIntent , "Send email...")); 
     } 
    }); 
} 

ich viel nach links aus der andere Code, der für meine Frage irrelevant ist, aber wenn jemand darauf hinweisen könnte, warum ich null werde, wäre das ein Lebensretter!

Answer 1

Sie benötigen extras.getString("Pilot");

insteadof extras.getString("pilot");

verwenden
