전달이 배열은 내가 자바와 안드로이드 developement에 내용을 시작하고 배열 변수

Question

을 텍스트 뷰에 적용하고 값을 출력하는 데 사용되는 다른 활동으로 내 MAINMENU 활동에서 사용자 정의 배열을 전달과 함께 붙어있어. 아무도 내가 잘못한 곳을 지적 할 수 있습니까?

MAINMENU 분류 :

public class MainMenu extends AppCompatActivity{ 

    SharedPreferences sharedVar; 
    Controller controller = new Controller(); 
    int size = 100; 
    Sati[] sati = new Sati[size]; 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main_menu); 
     sharedVar = this.getSharedPreferences("Var", MODE_WORLD_READABLE); 

    } 
    @Override 
    public void onResume(){ 
     super.onResume(); 

     for(int i = 0;i<size;i++) { 
      if (sati[i] != null){ 
       controller.upisiSmjenu(sati[i],sharedVar.getLong("Datum dolaska",0),sharedVar.getLong("Datum odlaska",0),sharedVar.getLong("Razlika",0)); 
      } 
     } 

    } 
    public void otvoriUnosLayout(View view) { 
     Intent intent = new Intent(this, UnosSati.class); 
     startActivity(intent); 
    } 
    public void otvoriPregledLayout(View view) { 

     Intent intent = new Intent(this, PregledSati.class); 
     intent.putExtra("Sati",sati); 
     startActivity(intent); 

    } 

} 

UnosSati 클래스 (데이터 입력을 위해 사용되는)

public class PregledSati extends AppCompatActivity { 


    TextView textView1,textView2,textView3,textView4,textView5,textView6; 
    Date dateD,dateO; 
    String printD,printO,printR; 
    Sati[] sati; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.pregled_sati); 

     dateD = new Date(); 
     dateO = new Date(); 
     printD = printO = printR = ""; 

     textView1 = (TextView) findViewById(R. id. txtIspis1); 
     textView2 = (TextView) findViewById(R. id. txtispis2); 
     textView3 = (TextView) findViewById(R. id. txtispis3); 


     Bundle extras = getIntent().getExtras(); 
     Sati[] sati = getIntent().getParcelableExtra("Sati"); 
     for(int i = 0;i<100;i++){ 
      textView1.append(String.valueOf(sati[i].getDateDolaska())); 
      textView1.append("\n"); 
     } 
    } 
} 

사티 클래스 :

public class UnosSati extends FragmentActivity { 

    SharedPreferences sharedVar; 
    TextView   txtRazlika; 
    Sati    sati; 
    Long    razlika; 
    Date    dateD,dateO; 
    int     danD,mjD,godD,SD,MD,danO,mjO,godO,SO,MO; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.unos_sati); 
     sharedVar = this.getSharedPreferences("Var",MODE_WORLD_READABLE); 
     sati = (Sati)getIntent().getParcelableExtra("Sati"); 
     dateD = new Date(); 
     dateO = new Date(); 



     txtRazlika = (TextView) findViewById(R. id. txtRazlika); 
     razlika = 0L; 
     txtRazlika.setText(String.valueOf(razlika)); 

     danD = sharedVar.getInt("DanD",0); 
     mjD  = sharedVar.getInt("MjD",0); 
     godD = sharedVar.getInt("GodD",0)-1900; 
     SD  = sharedVar.getInt("SD",0); 
     MD  = sharedVar.getInt("MD",0); 

     danO = sharedVar.getInt("DanO",0); 
     mjO  = sharedVar.getInt("MjO",0); 
     godO = sharedVar.getInt("GodO",0)-1900; 
     SO  = sharedVar.getInt("SO",0); 
     MO  = sharedVar.getInt("MO",0); 

     dateD.setDate(danD); 
     dateD.setMonth(mjD); 
     dateD.setYear(godD); 
     dateD.setHours(SD); 
     dateD.setMinutes(MD); 

     dateO.setDate(danO); 
     dateO.setMonth(mjO); 
     dateO.setYear(godO); 
     dateO.setHours(SO); 
     dateO.setMinutes(MO); 

     razlika =((dateO.getTime() - dateD.getTime())/60000)/60; 
     txtRazlika.setText(String.valueOf(razlika)); 


    } 
    public void vratiNaGlavni(View view){ 
     sharedVar.edit().putLong("Datum dolaska", dateD.getTime()).commit(); 
     sharedVar.edit().putLong("Datum odlaska", dateO.getTime()).commit(); 
     sharedVar.edit().putLong("Razlika",razlika).commit(); 
     Intent intent = new Intent(this,MainMenu.class); 
     startActivity(intent); 
    } 
    public void otvoriKalendarDolaskaLayout(View view) { 
     Intent intent = new Intent(this, Datum_dolaska.class); 
     startActivity(intent); 
    } 
    public void otvoriSatDolaskaLayout(View view) { 
     Intent intent = new Intent(this, Sat_dolaska.class); 
     startActivity(intent); 
    } 
    public void otvoriKalendarOdlaskaLayout(View view) { 
     Intent intent = new Intent(this, Datum_odlaska.class); 
     startActivity(intent); 
    } 
    public void otvoriSatOdlaskaLayout(View view) { 
     Intent intent = new Intent(this, Sat_odlaska.class); 
     startActivity(intent); 
    } 



} 

PregledSati 클래스는 데이터를보기 위해 사용

public class Sati implements Parcelable{ 

    public long dateDolaska, dateOdlaska,ukupnoVrijeme; 


    public Sati() { 
     super(); 
    } 

    public Sati(Parcel dest) { 
     this.dateDolaska=dest.readLong(); 
     this.dateOdlaska=dest.readLong(); 
     this.ukupnoVrijeme=dest.readLong(); 
    } 

    public long getDateDolaska() { return dateDolaska; } 
    public void setDateDolaska(long dateDolaska) { 
     this.dateDolaska = dateDolaska; 
    } 
    public long getDateOdlaska() { 
     return dateOdlaska; 
    } 
    public void setDateOdlaska(long dateOdlaska) { 
     this.dateOdlaska = dateOdlaska; 
    } 
    public long getUkupnoVrijeme() { 
     return ukupnoVrijeme; 
    } 
    public void setUkupnoVrijeme(long ukupnoVrijeme) { 
     this.ukupnoVrijeme = ukupnoVrijeme; 
    } 

    @Override 
    public int describeContents() { 
     return 0; 
    } 

    @Override 
    public void writeToParcel(Parcel dest, int flags) { 
     dest.writeLong(this.dateDolaska); 
     dest.writeLong(this.dateOdlaska); 
     dest.writeLong(this.ukupnoVrijeme); 
    } 

    public static final Creator<Sati> CREATOR=new Creator<Sati>() { 
     @Override 
     public Sati createFromParcel(Parcel dest) { 
      return new Sati(dest); 
     } 

     @Override 
     public Sati[] newArray(int size) { 
      return new Sati[size]; 
     } 
    }; 


} 

Answer 1

난 당신이 Parcelables의 배열을 얻고 클래스 사티가 Parcelable 있는지 확인해야하기 때문이라고 생각합니다.

Sati[] sati = getIntent().getParcelableArrayExtra("Sati"); 

Answer 2

어디 사티 클래스는 무엇입니까? Parcelable을 구현하고 Sati 클래스에서 메서드를 재정의해야합니다. 여기 봐 : https://developer.android.com/reference/android/os/Parcelable.html
