我决定开发一款Android应用程序,该应用程序使用的技术与我之前看过的应用程序非常相似.我想将多个按钮组合在一起,以等同于不同的文本结果.
Six dots – braille application (actual application to use)
这个我正在制作的本地盲文应用程序有6个不同的按钮,我希望每个独特的组合带给我不同的字母.例如：我想按下按钮1来简单地给我带来字母“A”.然后按下按钮1和按钮2不断给我带来字母“C”.我希望这6个按钮的每个不同的按钮组合给我一个单独的字母.
精通Java的人能否解释一下如何做到这一点？如何在多个按钮按下字符串以使我得到不同的结果？谢谢您的帮助.

我在java上的代码：

我的计时器代码：
Timer processtimer = new Timer(); processtimer.schedule(new TimerTask() { public voID run() { processinput(); } private voID processinput() { // Todo auto-generated method stub map.put(getString(R.ID.block1), "A"); map.put(getString(R.ID.block1) + getString(R.ID.block2), "C"); } }, 500); // Delay before processing. processtimer.cancel(); processtimer.schedule(new TimerTask() { public voID run() { processinput(); } private voID processinput() { // Todo auto-generated method stub map.get(R.ID.block1); map.get(R.ID.block1+R.ID.block2); //this.close(); } }, 500);这个对吗？
解决方法:
我尝试使用类似于aptyp的建议的方法进行编码：
