我尝试使用类似于aptyp建议的方法进行编码：
MainActivity.java：
public class MainActivity extends AppCompatActivity implements View.OnClickListener{static long DELAY_TIME_INPUT = 500;static int INPUT_TYPE_NORMAL = 0;static int INPUT_TYPE_CAP = 1;static int INPUT_TYPE_NUM = 2;TextView txtMessage;int[] mAlphabetTable1 = new int[]{1, 3, 9, 25, 17, 11, 27, 19, 10, 26, 5, 7, 13, 29, 21, 15, 31, 23, 14, 30, 37, 39, 58, 45, 61, 53};int[] mSymbolTable1 = new int[]{2, 6, 4, 18, 36, 40, 50, 22, 38, 52, 54, 12};int[] mSpecialTable1 = new int[]{8, 16, 20, 24};// char[] mAlphabetTable2 = new char[]{};char[] mNumberTable2 = new char[]{'1', '2', '3', '4', '5', '6', '7', '8', '9', '0'};char[] mSymbolTable2 = new char[]{',', ';', ''', ':','-', '.', '.', '!', '“', '”','(','/'};int mCurrentAlphabet = 0;int mCurrentInputType = 0;long mLastTimeStamp;@Overrideprotected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); Window window = this.getWindow(); window.addFlags(WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD); window.addFlags(WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED); window.addFlags(WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON); // Init GUI txtMessage = (TextView) 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); Button buttonFive = (Button) findViewById(R.id.block5); Button buttonSix = (Button) findViewById(R.id.block6); // Attached Click Listener buttonOne.setonClickListener(this); buttonTwo.setonClickListener(this); buttonThree.setonClickListener(this); buttonFour.setonClickListener(this); buttonFive.setonClickListener(this); buttonSix.setonClickListener(this);}@Overridepublic void onClick(View view) { switch (view.getId()){ case R.id.block1: mCurrentAlphabet |=1; break; case R.id.block2: mCurrentAlphabet |=2; break; case R.id.block3: mCurrentAlphabet |=4; break; case R.id.block4: mCurrentAlphabet |=8; break; case R.id.block5: mCurrentAlphabet |=16; break; case R.id.block6: mCurrentAlphabet |=32; break; } view.setBackgroundColor(Color.BLACK); Button btView = (Button) view; btView.setTextColor(Color.WHITE); mLastTimeStamp = System.currentTimeMillis(); Handler handler = new Handler(); handler.postDelayed(new Runnable() { @Override public void run() { long currentTimeStamp = System.currentTimeMillis(); if(currentTimeStamp - mLastTimeStamp > DELAY_TIME_INPUT){ genNewBrailleAlphabet(); } } }, DELAY_TIME_INPUT + 10);}public void genNewBrailleAlphabet(){ if(mCurrentAlphabet == 32 || mCurrentAlphabet == 60){ // Check if input is Cap or Num sign? if(mCurrentAlphabet == 32){ // Input is Cap sign. mCurrentInputType = INPUT_TYPE_CAP; TextView txtCap = (TextView) findViewById(R.id.cap); txtCap.setBackgroundColor(Color.GREEN); } else { // Input is Num sign.

String tmpString = txtMessage.getText().toString(); if(tmpString.length() > 0 && !tmpString.endsWith(" ")){ // Last typed alphabet is not space, so this is Question Mark. newAlphabet = '?'; } } String msg = txtMessage.getText().toString() + newAlphabet; txtMessage.setText(msg); } else { // Input is not Punctuations, so it is Special Action or undefined. for (int i = 0; i < mSpecialTable1.length; i++) { if (mSpecialTable1[i] == mCurrentAlphabet) { currentAlphabetIndex = (byte) i; break; } } if(currentAlphabetIndex != -1) { // Check if input is Special Action?

请注意，我使用的是处理程序，而不是计时器。希望对您有所帮助！
