Select all text when EditText has focus doesn"t work

When an EditText has a focus, I want to select all text inside by default, but it doesn't work:
editText.setOnFocusChangeListener(new OnFocusChangeListener() {
#Override
public void onFocusChange(View view, boolean hasFocus) {
if (hasFocus) {
// Go to the end
editText.setSelection(getEditTextView().getText().length());
// Select all the content
editText.selectAll();
}
}
});
Thank you very much guys!

There are 2 good way to select the text in an EditText :
Inside your main.xml :
android:selectAllOnFocus="true"
Or :
editText.setSelectAllOnFocus(true);
(If you want to do it programatically)

how to lose focus on a text field when I press enter or anywhere else on the screen?

My scenario is as it follows: I have a search fragment and in that fragment, I have 3 text fields(Search by name, by zip code and by distance). When the focus is applied on the "Search by name" field, the other 2 fields dissapear and the width of the selected field increases. My problem is that I can't lose focus of the first field and so, after I am done with writing the information, I can't use the other 2 fields.
What I am looking for is a way to lose focus of the fields when I press "enter" or when I press anywhere else on the screen but the text field.
Here is the code that I am running right now:
final EditText searchByName = (EditText) getActivity().findViewById(R.id.search_by_name);
final EditText searchByZipcode = (EditText) getActivity().findViewById(R.id.search_by_zipcode);
final EditText searchByDistance = (EditText) getActivity().findViewById(R.id.search_by_distance);
searchByName.setOnFocusChangeListener(new View.OnFocusChangeListener() {
#Override
public void onFocusChange(View v, boolean hasFocus) {
/* When focus is lost check that the text field
* has valid values.
*/
if (hasFocus) {
searchByName.getLayoutParams().width=900;
searchByZipcode.setVisibility(View.INVISIBLE);
searchByDistance.setVisibility(View.INVISIBLE);
} else {
searchByName.getLayoutParams().width=405;
searchByZipcode.setVisibility(View.VISIBLE);
searchByDistance.setVisibility(View.VISIBLE);
}
}
});
searchByZipcode.setOnFocusChangeListener(new View.OnFocusChangeListener() {
#Override
public void onFocusChange(View v, boolean hasFocus) {
/* When focus is lost check that the text field
* has valid values.
*/
if (hasFocus) {
searchByZipcode.getLayoutParams().width=700;
searchByName.setVisibility(View.INVISIBLE);
} else {
searchByZipcode.getLayoutParams().width=240;
searchByName.setVisibility(View.VISIBLE);
}
}
});

Inside your Activity Class , add this below method , it will work for you .It will hide keyboard and will clear focus anywhere outside you click in that one it will work .
#Override
public boolean onTouchEvent(MotionEvent event) {
InputMethodManager imm = (InputMethodManager) getSystemService(Context.
INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(), 0);
return true;
}

Disabling edittext searchview after user input

How to disable EditText searchview after completion of input on fragment?

You can set View.OnFocusChangeListener to your editText and after focus change call setEnabled(false). for eg.
mEditText.setOnFocusChangeListener(new OnFocusChangeListener() {
#Override
public void onFocusChange(View view, boolean hasFocus) {
if (hasFocus) {
//let the user input
} else {
//disable you search view
mEditText.setEnabled(false);
}
}
});
P.S. -If you are still facing a problem, please update your code snippet.

If user have to click button after enter text into searchview, you can handle this in event button click method. In your button click method you can write:
search.setEnabled(false);

Android - Do something *after* text is changed in EditText

I build an android application. I have an EditText. I want to save changes (or anything else) automatically after the user change the text.
Now I use
editText.addTextChangedListener(textWatcher);
and
TextWatcher textWatcher = new TextWatcher() {
public void afterTextChanged(Editable s) {
...
}
But it saves the changes after every little change (add \ remove a letter), and I want that it'll be saved only after the user finished (closed the keyboard, clicked on a different edittext, etc. ).
How can I do that?

Implement onFocusChange of setOnFocusChangeListener and there's a boolean parameter for hasFocus. When this is false, you've lost focus to another control and you should save the data of editext. for example
EditText editText= (EditText) findViewById(R.id.editText);
editText.setOnFocusChangeListener(new OnFocusChangeListener() {
public void onFocusChange(View v, boolean hasFocus) {
if(!hasFocus) {
//SAVE THE DATA
}
}
});
Implement setOnFocusChangeListener for all EditTexts and you should handle Back Press event too. If the user change the data of edittext and didn't goto another EditText and pressed back then edited vallue will not save. So should use onKeyDown or onBackPressed too

As Kotlin is now official android language:
var editText = findViewById<EditText>(R.id.editText)
editText.onFocusChangeListener = OnFocusChangeListener { _, hasFocus ->
if (!hasFocus) {
//SAVE THE DATA
}
}

EditText focus lost

In a custom ListView, there are two columns, one contains a TextView and the other a EditText component.To enter some preferences, as the user clicks on the EditText, the software keyboard comes in focus but focus from the EditText is lost. How I can do this?

Focusable EditText inside ListView

For editText use method setFocusable(false).
For textView use setFocusable(true).
Also write a listener on focus lost for both textView and editText:
textView.setOnFocusChangeListener(new OnFocusChangeListener() {
public void onFocusChange(View v, boolean hasFocus) {
if(!hasFocus)
{
//do job here when EditText loses focus
}
}
});
