java - 如何只激活最后两次点击？

Question

我需要另一种方法来解决我的问题。因此，每当我单击一个按钮(我有 16 个按钮)时，它会保持“Activity ”状态并等待 buttonClicked.getTag().equals(button.getTag())) 如果语句为真。这对我来说太糟糕了。因此，我单击第一个按钮，然后单击第二个、第三个、第四个、第五个，假设第 5 个按钮与我单击的第一个按钮具有相同的标签，现在第一个和第五个按钮配对并禁用。如何只计算最后两次单击的按钮？因此，在我的示例中，我需要第 5 个单击按钮来与第 4 个按钮进行比较，而不是与第 1 个按钮进行比较。但是第一个一直保持活跃。

final OnClickListener clickListener = new OnClickListener() {

            private Button buttonClicked;

            public void onClick(View v) {
                Button button = (Button) v;
                button.getBackground().setColorFilter(new LightingColorFilter(0xFFFFFFFF, 0x003333));

                if (buttonClicked == null) {
                    // first button is clicked
                    buttonClicked = button;
             } else if (buttonClicked.getParent() != button.getParent()) {
                    // second button is clicked
                    if (buttonClicked.getTag().equals(button.getTag())) {
                        Toast.makeText(Spojnice.this, "Correct", Toast.LENGTH_SHORT).show();
                        button.getBackground().setColorFilter(new LightingColorFilter(0xFFFFFFFF, 0x66FF33));
                        buttonClicked.getBackground().setColorFilter(new LightingColorFilter(0xFFFFFFFF, 0x66FF33));
                        buttonClicked.setEnabled(false);
                        button.setEnabled(false);
                    } else {
                        Toast.makeText(Spojnice.this, "Wrong", Toast.LENGTH_SHORT).show();

                    }
                 buttonClicked = null;
                }       
            }

     };

因此，在下面的屏幕显示中，我先按了水瓶座，然后是双鱼座，然后是十字座，然后是天鹰座，最后是沃多利亚。所以它一直记得我的第一次点击，然后一旦满足它们不是来自同一父级(不在同一线性布局中)的条件，它就会比较它们。这是我的问题。我只需要比较最后两个点击，在本例中是 Aquila 和 Vodolija。这将导致错误的答案，因为他们不是一对，但现在这无关紧要。因此，当我单击右侧布局中的第一个按钮(在本例中为 Vodlija)时，我需要将其与左侧布局中单击的最后一个按钮进行比较，而不是第一个，在本例中为 Aquila。如何做到这一点？
