Example 1 – Listener for EditText on Text ChangeRun this Android Application in your Android phone or Emulator. You would get an EditText on the screen. Try entering some text into EditText. When text changes in EditText, onTextChanged() method is called, and we are updating the text of TextView.
TextWatcher. When TextWatcher object is attached to an Editable, its methods will be called when the text is changed. So, TextWatcher object can be used as a listener for text changes in the EditText.
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. The .... is just saying that you can put it anywhere else in the class.
You can register an OnFocusChangeListener on your EditText inside your activity's onCreate method:
final EditText et = (EditText)findViewById(R.id.my_edit_text);
et.setOnFocusChangeListener(new View.OnFocusChangeListener()
{
@Override
public void onFocusChange(View v, boolean hasFocus)
{
if (!hasFocus)
// TODO: the editText has just been left
}
});
Here the v parameter of the onFocusChange is your EditText control.
Also, if you want to update your TextView on every change in the EditText's content, you should put your update code inside the public void afterTextChanged(Editable s) method of the registered TextWatcher.
//Make sure, that the txtRisk TextView is part of the dialogbetNow view.
