java – 在多个类中共享常量(android minesweeper)

我有常量声明Button类和Activity类中实例化它们.我发现了类似的问题,并且读取它只是为了保持常量而创建一个类是不好的做法.

在两个类中使用相同的常量声明的最佳方法是什么？

我是初学程序员,所以我很有可能忽略了一个简单的解决方案.

按钮类：

public class GridButton extends Button {
  public int displayStatus;

  // constants for mine display status
  private static final int UNTOUCHED = 1;
  private static final int UNCOVERED = 2;
  private static final int FLAGGED = 3;
  private static final int HIT = 4;
  ...
}

活动类：

public class PlayGameActivity extends Activity {      
  private GridButton[][] gridButtons;      

  // constants for mine display status
  private static final int UNTOUCHED = 1;
  private static final int UNCOVERED = 2;
  private static final int FLAGGED = 3;
  private static final int HIT = 4;
  ...

  // e.g. accessing displayStatus value
  if (gridButtons[currentRow][currentColumn].displayStatus == FLAGGED)
  {
  }
}
