I have a EditText
. I wamt tp do something, when the user presses the Enter key while changing EditText
. How can I do that?
The most simplest method:
final EditText edittext = (EditText) findViewById(R.id.edittext);
edittext.setOnKeyListener(new OnKeyListener() {
public boolean onKey(View v, int keyCode, KeyEvent event) {
// If the event is a key-down event on the "enter" button
if ((event.getAction() == KeyEvent.ACTION_DOWN) &&
(keyCode == KeyEvent.KEYCODE_ENTER)) {
// Perform action on key press
Toast.makeText(HelloFormStuff.this, edittext.getText(), Toast.LENGTH_SHORT).show();
return true;
}
return false;
}
});
You can use View. OnFocusChangeListener to detect if any view (edittext) gained or lost focus. This goes in your activity or fragment or wherever you have the EditTexts.
Now, before we start we need to know some method of EditText which we use to get or fetch the text written in an EditText that is . getText() method and the other one is . setText() method that we use to set some pre-written text or string. EditText demo; demo=(EditText)findViewById(R.
sample code for text watcher
your_edittext.addTextChangedListener(new InputValidator());
private class InputValidator implements TextWatcher {
public void afterTextChanged(Editable s) {
}
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
}
public void onTextChanged(CharSequence s, int start, int before,
int count) {
}
}
}
