如何在自定義對話框按鈕中使用意圖？

Question

我有我的對話框，這是在XML文件中編碼兩個按鈕：

<Button 
    android:id="@+id/continuegame" 
    style="?android:attr/buttonStyleSmall" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_below="@+id/resulttext" 
    android:layout_marginRight="26dp" 
    android:layout_marginTop="23dp" 
    android:layout_toLeftOf="@+id/backmain" 
    android:onClick="continueGame" 
    android:text="@string/label_continue" /> 

<Button 
    android:id="@+id/backmain" 
    style="?android:attr/buttonStyleSmall" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_alignBaseline="@+id/continuegame" 
    android:layout_alignBottom="@+id/continuegame" 
    android:layout_alignParentRight="true" 
    android:layout_marginRight="52dp" 
    android:onClick="backToMain" 
    android:text="@string/label_mainmenu" /> 

我已經成功地調用對話框，但問題是，當我點擊要麼繼續或返回主菜單按鈕，該應用程序崩潰。

這是我在我的GuessActivity.java代碼：

//when Submit button is clicked this method is called 
public void checkAnswer(View view){ 
    EditText userinput = (EditText) findViewById(R.id.inputLetter); 
    String temp = userinput.getText().toString(); 
    char userletter = temp.charAt(0); 

    Bundle fromplay = getIntent().getExtras(); 
    String temp2 = fromplay.getString("missing"); 
    char missingletter = temp2.charAt(0); 

    Log.d ("temp2", temp2); 

    if(userletter == missingletter){ 
     Log.d ("right", "right"); 
     correct = 1; 
     //will call a dialog box 
     resultDialogBox(correct); 
    } else { 
     Log.d ("wrong", "wrong"); 
     correct = 0; 
     //will call a dialog box 
     resultDialogBox(correct); 
    } 


} 

//the dialog box 
public void resultDialogBox(int correct){ 
    this.correct = correct; 
    Dialog resultbox = new Dialog(GuessActivity.this); 
    resultbox.setContentView(R.layout.dialog_result); 
    resultbox.setCanceledOnTouchOutside(false); 
    TextView result = (TextView) resultbox.findViewById(R.id.resulttext); 


    if(correct == 1){ 
     result.setText("Correct!"); 
    } else { 
     result.setText("Wrong!"); 
    } 

    resultbox.show(); 

} 

//method of the continue button 
public void continueGame(View view){ 
    Intent con = new Intent(GuessActivity.this, PlayActivity.class); 
    GuessActivity.this.startActivity(con); 
} 

//method of the back to main button 
public void backToMain(View view){ 
    Intent backtomain = new Intent(GuessActivity.this, MainActivity.class); 
    GuessActivity.this.startActivity(backtomain); 
} 

的logcat的：

試試這個..

public void resultDialogBox(int correct){ 
    this.correct = correct; 
    Dialog resultbox = new Dialog(GuessActivity.this); 
    resultbox.setContentView(R.layout.dialog_result); 
    resultbox.setCanceledOnTouchOutside(false); 
    TextView result = (TextView) resultbox.findViewById(R.id.resulttext); 
    Button continuegame = (Button) resultbox.findViewById(R.id.continuegame); 
    Button backmain = (Button) resultbox.findViewById(R.id.backmain); 

    if(correct == 1){ 
     result.setText("Correct!"); 
    } else { 
     result.setText("Wrong!"); 
    } 

    continuegame.setOnClickListener(new OnClickListener() { 

      @Override 
      public void onClick(View v) { 
        Intent con = new Intent(GuessActivity.this, PlayActivity.class); 
        GuessActivity.this.startActivity(con); 
      } 
    }); 

    backmain.setOnClickListener(new OnClickListener() { 

      @Override 
      public void onClick(View v) { 
        Intent backtomain = new Intent(GuessActivity.this, MainActivity.class); 
        GuessActivity.this.startActivity(backtomain); 
      } 
    }); 

    resultbox.show(); 

} 

和刪除都android:onClick="backToMain"和android:onClick="continueGame"從XML
