Android：一个接一个地点击一到六个按钮，将不同的结果串在一起 [英] Android: Tapping one to six buttons continuously [one after another] to string together different results
本文介绍了Android：一个接一个地点击一到六个按钮，将不同的结果串在一起的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我已经决定在Android应用程序上使用与之前所见过的应用程序非常相似的技术。我想将多个按钮按压在一起，以等同于不同的文本结果。
I have decided to work on an Android app that uses very similar technology to that of an app I have seen before. I wanted to string together multiple button presses to equate to different a different text result.
我制作的本机盲文应用程序有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：我想点击按钮1来简单地给我写信A。然后按下按钮1和按钮2不断地给我带来字母C。我想要这六个按钮的每个不同的按钮组合给我一个单独的信。
This native braille app I am making has 6 different buttons that I would like to have every unique combination bring me different letters. For example: I would like hitting button 1 to simple bring me the letter "A". Then hitting button 1 and button 2 continuously brings me the letter "C". I want every different button combination of these 6 buttons to bring me a seperate letter.
有能力熟练掌握Java的人可以解释这个做法吗？如何在多个按钮按下字符串来带给我不同的结果？感谢您的帮助。
Can someone who is proficient at Java please explain how this is done? How can I string in multiple button presses to bring me to a different result? Thanks for the help.
我的java代码：
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.keyboard);
Window window = this.getWindow();
window.addFlags(LayoutParams.FLAG_DISMISS_KEYGUARD);
window.addFlags(LayoutParams.FLAG_SHOW_WHEN_LOCKED);
window.addFlags(LayoutParams.FLAG_TURN_SCREEN_ON);
// Init GUI
txtMessage = (EditText) findViewById(R.id.txtMesssage);
Button buttonOne = (Button) findViewById(R.id.block1);
Button buttonTwo = (Button) findViewById(R.id.block2);
Button buttonThree = (Button) findViewById(R.id.block3);
Button buttonFour = (Button) findViewById(R.id.block4);

// Attached Click Listener

到目前为止，我不想工作，所以我现在离开开关语句为空。请纠正我的代码或帮助我这个。感谢
The code that I have made so far is not working as I wanted it to, so I leave the switch statement blank for now. Please correct me on my codes or help me with this one. Thanks
我的计时码：
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);
这是否正确？

我尝试使用类似于aptyp的建议的方法进行代码：
I tried to code with a method that similar to the suggestion by aptyp:
MainActivity.java：
