我不能將int值從一個活動轉移到另一個

Question

在第一個活動中我有一個代數運算，我需要將結果從第一個活動傳遞到第二個活動。我查看了我發現的所有內容，但我是一名Android初學者，所以我找不到真正的問題。

這是第一個活動：

import android.content.Intent; 
import android.os.Bundle; 
import android.view.View; 
import android.widget.EditText; 
import android.widget.TextView; 

public class Contar extends MainActivity{ 

public EditText et1, et2, et3; 
public TextView tv1; 

protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.contar); 

    et1=(EditText)findViewById(R.id.et1); 
    et2=(EditText)findViewById(R.id.et2); 
    et3=(EditText)findViewById(R.id.et3); 
    tv1=(TextView)findViewById(R.id.tv1); 
} 

public void contarbesos(View view){ 

    String meses=et1.getText().toString(); 
    String bd=et2.getText().toString(); 
    String dsvs=et3.getText().toString(); 

    int nro1=Integer.parseInt(meses); 
    int nro2=Integer.parseInt(bd); 
    int nro3=Integer.parseInt(dsvs); 

    int sm=4; 
    int dsvm; 
    int dvm; 
    int dr; 
    int besos; 
    int dsv; 

    dr=nro1*30; 

    dsv=nro3*sm; 

    dsvm=nro1*dsv; 
    dvm=dr-dsvm; 
    besos=dvm*nro2; 

    Intent i = new Intent(this, Resultado.class); 
    i.putExtra("besos", besos); 
    startActivity(i); 


    } 
} 

第二活動：

import android.content.Intent; 
import android.os.Bundle; 
import android.widget.TextView; 

public class Resultado extends Contar { 

public TextView tv1; 

public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.resultado); 

    tv1=(TextView)findViewById(R.id.tv1); 

    Bundle bundle = getIntent().getExtras(); 
    String intValue = bundle.getString("besos"); 
    tv1.setText(intValue); 


} 

} 

和誤差在logcat的（修訂版）：

Answer 1

「貝索斯」 是一個INT。您必須使用getInt (String key, int defaultValue)才能獲得其價值。

int intValue = bundle.getInt("besos", 0); 
tv1.setText(String.valueOf(intValue));
