Answer 1

EditText et = (EditText) findViewById(R.id.EditText01); et.addTextChangedListener( new TextWatcher() { @Override public void onTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) { try { char currentChar = arg0.charAt(arg1); // currently typed character } catch(Exception e) { // error } } @Override public void beforeTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) { } @Override public void afterTextChanged(Editable arg0) { } }); 

Answer 2

You can use the TextView.addTextChangedListener(TextWatcher watcher) method

TextWatcher provides 3 great methods:

 public abstract void afterTextChanged (Editable s) public abstract void beforeTextChanged (CharSequence s, int start, int count, int after) public abstract void onTextChanged (CharSequence s, int start, int before, int count)

Answer 3

It would be much simpler to simply override onKeyDown() as follows:

 @Override public boolean onKeyDown(int keyCode, KeyEvent event) { switch (keyCode) { case KeyEvent.KEYCODE_Q: // Do your thing here. break; } return super.onKeyDown(keyCode, event); } 

Answer 4

Take a look at the setOnKeyListener method in EditText.

Answer 6

Vikas's answer almost worked for me, but not quite. Here is what I did to get a typical character printed:

 EditText et = ...; et.addTextChangedListener(new TextWatcher() { @Override public void beforeTextChanged(CharSequence s, int start, int count, int after) { } @Override public void afterTextChanged(Editable editable) { } @Override public void onTextChanged(CharSequence s, int start, int count, int after) { if (s.length() > start + count) { char c = s.charAt(start + count); // do something ... } } });
