我的android應用程序在調試時沒有找到源碼

Question

您好，我是一名學習Java的大學生。我正在研究一個android應用程序。它編譯並顯示沒有錯誤。但是，當它運行時，會出現意外的關閉錯誤。

這裏是我的應用程序。當你點擊計算ws時，你的目的是改變到這個屏幕。

這裏是我的代碼：

package com.warhammerdicerrolleralpha; 


import android.app.Activity; 
import android.os.Bundle; 
import android.view.View; 
import android.view.View.OnClickListener; 
import android.widget.Button; 
import android.widget.EditText; 
import android.widget.ImageView; 
import android.widget.TextView; 

public class myMain extends Activity 
{ 

    EditText enternumberofdice; 

    final TextView textGenerateNumber = (TextView) findViewById(R.id.text4); 

    private EditText text, text2, text3; 

    private Button btutorial1; 

    int number1 = Integer.parseInt(text.getText().toString()); 

    int number2 = Integer.parseInt(text2.getText().toString()); 

    ImageView i = new ImageView(this); 
    { 
     i.setAdjustViewBounds(true); 
    } 

    private int myFaceValue; 

    int myNum; 

    /** 
    * Called when the activity is first created. 
    * 
    * @return 
    */ 
    @Override 

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

    public void go() 
    { 
     while (myNum > 0) 
     { 

      // TODO Auto-generated method stub 
      textGenerateNumber.setText(String.valueOf(enternumberofdice)); 

      --myNum; 

      return; 
     } 
    } 

    public int roll() 
    { 
     int val = (int) (6 * Math.random() + 1); // Range 1-6 
     setValue(val); 
     return val; 
    } 

    { 
     try 
     { 
      myNum = Integer.parseInt(enternumberofdice.getText().toString()); 
     } 
      catch (NumberFormatException nfe) 
     { 
      enternumberofdice.setText("Does not work"); 
     } 
    } 

    public int getValue() 
    { 
     return myFaceValue; 
    } 

    public void setValue(int myFaceValue) 
    { 
     this.myFaceValue = myFaceValue; 

    } 

    { 
     switch (myFaceValue) 
     { 
     case 5: 
      i.setImageResource(R.drawable.dicefive); 
      break; 
     case 1: 
      i.setImageResource(R.drawable.diceone); 
      break; 
     case 3: 
      i.setImageResource(R.drawable.dicethree); 
      break; 
     case 2: 
      i.setImageResource(R.drawable.dicetwo); 
      break; 
     case 4: 
      i.setImageResource(R.drawable.dicefour); 
      break; 
     case 6: 
      i.setImageResource(R.drawable.dicesix); 
      break; 
     default: 
      i.setImageResource(R.drawable.error); 
      break; 
     } 

     text = (EditText) findViewById(R.id.editText1); 

     text2 =(EditText) findViewById(R.id.editText2); 

     text3 = (EditText) findViewById(R.id.editText3);  

     btutorial1 = (Button) findViewById(R.id.button1); 

     btutorial1.setOnClickListener((OnClickListener) this); 

     Button buttonGenerate = (Button) findViewById(R.id.button1); 

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

     Button buttonGenerate2 = (Button) findViewById(R.id.battlecalculate); 

     buttonGenerate2.setOnClickListener(new OnClickListener()  
     { 

      @Override 
      public void onClick(View v) 
      { 
        setContentView(R.layout.main2); 
      } 

     }); 

     buttonGenerate.setOnClickListener(new OnClickListener()  
     { 
      @Override 
      public void onClick(View v) 
      { 
       // TODO Auto-generated method stub 
       go(); 

       roll(); 
      } 

     }); 
    } 

    public void onClick(View view) 
    { 
     switch (view.getId()) 
     { 
      case R.id.button1: 

       if (number1 > number2) 
       { 
        text3.setText("Three and above");  
        return; 
       } 

       else if (number1 < number2) 
       { 
        text3.setText("Five and above");   
        return; 
       } 

       else if (number1 == number2) 
       { 
        text3.setText("Four and above");   
        return; 
       } 

       else 
       { 
        text3.setText("Not Working");  
        return; 
       } 

     } 
    } 
} 

Answer 1

看看你的堆棧跟蹤，但我認爲這可能是因爲此塊：

private EditText text, text2, text3; 

private Button btutorial1; 

int number1 = Integer.parseInt(text.getText().toString()); 

int number2 = Integer.parseInt(text2.getText().toString()); 

它看起來好像你是在空試圖parseInt函數值。你需要使用類似的代碼來指定文本，text2，text3在你的表單中的位置：

TextView textGenerateNumber = (TextView) findViewById(R.id.text4); 

希望有所幫助。
