而(flagCounter如果让Eclipse重新格式化所有代码,我认为您会发现问题所在。我怀疑问题出在第210-229行:

for (int row = 0; row < guessRows; row++)
{
    TableRow currentTableRow = getTableRow(row);
}
//place Buttons in currentTableRow
    for (int column = 0; column < 3; column ++)
    {
        //inflate guess_button.xml to create new Button
        Button newGuessButton = 
            (Button) inflater.inflate(R.layout.guess_button, null);

        //get country name and set it as newGuessButton's text
        String fileName = fileNameList.get((row * 3) + column);
        newGuessButton.setText(getCountryName(fileName));

        //register answerButtonListener to respond to button
        newGuessButton.setOnClickListener(guessButtonListener);
        currentTableRow.addView(newGuessButton);
    }//end for
