I know how to listen for when the ENTER button is pressed in a TextView, as shown in the code below:
textView.setOnKeyListener(new View.OnKeyListener() {
public boolean onKey(View v, int keyCode, KeyEvent event) {
if((event.getAction() == KeyEvent.ACTION_DOWN) && (keyCode == KeyEvent.KEYCODE_ENTER)) {
enterPressed();
return true;
}
return false;
}
});
However... how do I listen for when a character key (A-Z, 0-9, special characters, etc.), basically everything else other than ENTER, BACKSPACE, or SPACE, are pressed? I want to do this because I want a button to become enabled when the user has started typing text into a TextView. Strangely, the onKey() method isn't even called when these character keys are pressed, so is there another way I'm suppose to listen for them? Thanks in advance!
Text watcher might help you
textView.addTextChangedListener(new TextWatcher(){
@Override
public void afterTextChanged(Editable arg0) {
// TODO Auto-generated method stub
}
@Override
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
// TODO Auto-generated method stub
}
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
// TODO Auto-generated method stub
}
});
