答案 0 :(得分：0)
问题在于您将文本设置为int。比如下面的行
highScoreText.setText（currentPlayer.getHighScore（））;
如果getHighScore（）返回int，则os将在string.xml中查找资源，该资源将为您提供 .Resources $ NotFoundException 。尝试使用它如下。
highScoreText.setText(String.valueOf(currentPlayer.getHighScore()));
或者
highScoreText.setText(currentPlayer.getHighScore()+"");
