안드로이드 버튼 클릭시 작동 중지 질문드립니다.

Question

안녕하세요 

안드로이드 초보자 입니다.

제가 만든 어플을 실행하면 실행은 되는데 버튼을 누르면 어플이 중지 되어 버리는 현상때문에 이렇게

글을 남깁니다.

안드로이드 .java소스는

package com.mokwon.myshopping;

 

import com.mokwon.myshopping.R;

 

import android.app.Activity;

import android.os.Bundle;

import android.view.View;

import android.widget.Button;

import android.widget.EditText;

import android.widget.TextView;

import android.widget.Toast;

 

public class Sale extends Activity {

EditText SeditText1, SeditText2;

TextView text6, text7;

double result3, result4;

double n1, n2;

String Snum1, Snum2;

 

View.OnClickListener bHandler = new View.OnClickListener() {

 

@Override

public void onClick(View v) {

// TODO Auto-generated method stub

switch (v.getId()) {

case R.id.reckoning2:

doreckoning2();

text6.setText(String.format("%.0f",result3) + "원 입니다.");

text7.setText(String.format("%.0f",result4)+ "원 입니다.");

break;

case R.id.clear2:

doinit1();

break;

}

 

}

};

 

void doreckoning2(){

Snum1 = SeditText1.getText().toString();

Snum2 = SeditText2.getText().toString();

n1 = Double.valueOf(Snum1);

n2 = Double.valueOf(Snum2);

 

result4 = (Double.valueOf(SeditText1.getText().toString())) - (Double.valueOf((n1*n2)/100));

result3 = (Double.valueOf(SeditText1.getText().toString()) - Double.valueOf(result4));

 

}

 

void doinit1() {

 

SeditText1.setText(" ");

SeditText2.setText(" ");

text6.setText(" ");

text7.setText(" ");

Toast.makeText(getApplicationContext(), "Clear", 0).show();

 

}

 

/** Called when the activity is first created. */

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

 

// TODO Auto-generated method stub

 

setContentView(R.layout.sale);

 

SeditText1 = (EditText) findViewById(R.id.SeditText1);

SeditText2 = (EditText) findViewById(R.id.SeditText2);

 

findViewById(R.id.reckoning2).setOnClickListener(bHandler);

findViewById(R.id.clear2).setOnClickListener(bHandler);

 

text6 = (TextView) findViewById(R.id.textView6);

text7 = (TextView) findViewById(R.id.textView7);

 

Button before2 = (Button) findViewById(R.id.before2);

 

 

before2.setOnClickListener(new View.OnClickListener() {

 

@Override

public void onClick(View v) {

finish();

}

});

 

}

 

}

이렇게 작성하였는데 

빨간색 줄 라인에 빨간줄도 없고 에러도 없는것같은데

메인에서 저화면으로 넘어가는 버튼을 누르면 중지되네요 ㅠㅠ

안펍 여러분 도와주세요 ㅠㅠ

어떤게 문제일까요?
