I know a little bit about TextWatcher
but that fires on every character you enter. I want a listener that fires whenever the user finishes editing. Is it possible? Also in TextWatcher
I get an instance of Editable
but I need an instance of EditText
. How do I get that?
EDIT: the second question is more important. Please answer that.
First, you can see if the user finished editing the text if the EditText
loses focus or if the user presses the done button (this depends on your implementation and on what fits the best for you).
Second, you can't get an EditText
instance within the TextWatcher
only if you have declared the EditText
as an instance object. Even though you shouldn't edit the EditText
within the TextWatcher
because it is not safe.
EDIT:
To be able to get the EditText
instance into your TextWatcher
implementation, you should try something like this:
public class YourClass extends Activity {
private EditText yourEditText;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
yourEditText = (EditText) findViewById(R.id.yourEditTextId);
yourEditText.addTextChangedListener(new TextWatcher() {
public void afterTextChanged(Editable s) {
// you can call or do what you want with your EditText here
// yourEditText...
}
public void beforeTextChanged(CharSequence s, int start, int count, int after) {}
public void onTextChanged(CharSequence s, int start, int before, int count) {}
});
}
}
Note that the above sample might have some errors but I just wanted to show you an example.
