Question

我有一堆按钮，并分配了一些条款。我希望用户按照他们的意思连接它们。无论如何，我需要当用户按下按钮时，没有任何事情发生，只是可能为它设置颜色，并等到他按下另一个，然后采取一些行动（在我的情况下比较setText中的术语）纽扣）。再次，当他按下下一个按钮时，没有任何事情发生，直到他按下第四个按钮等等。我怎样才能做到这一点？我已完成所有工作，直到这一部分，我已导入数据库，为我的按钮指定文本等等。

编辑：

好的，这就像斯蒂芬问的那样。我为所有按钮使用一个onClickListener。我为他们分配了一个标签（正确的我希望......我使用相同的标签进行正确的配对），我稍后会用它来检查正确的答案（仍在学习）。我按下按钮改变它的颜色，现在我需要它等到我按下ArrayList labelB中的其他按钮。如果我按下labelA组按钮上的按钮，我不想发生任何事情，只改变颜色。也许你们认为“哇这么简单而且蹩脚”但现在对我来说这太复杂了。：）

Button a1,a2,a3,a4,a5,a6,a7,a8,b1,b2,b3,b4,b5,b6,b7,b8;
//private boolean mShouldTakeAction; does not need this anymore
private Button mDisableButton;
.......
.......
final OnClickListener clickListener = new OnClickListener() {
    public void onClick(View v) {

     // We are going to disable button so no need to make it yellow
     //Button button = (Button)v;
     //button.setBackgroundColor(Color.YELLOW);
     if (mDisableButton == null)
     {

           mDisableButton = (Button) v;
           v.setEnabled(false);
     }
     else
     {
          mDisableButton.setEnabled(true);
          mDisableButton = null;
          // do what ever you want here that is compare the terms
     }



        }
 };

如何等到按下第二个按钮？
