Android EditText setText not updating the text
Hi there. I dont know what is happening. I am trying to change the text of an EditText when creating a DialogFragment , but the EditText is not updating the text. If I call getText().length() I notice that the content of the EditText changed. But, the visual keeps the same, just empty.
Why?
Thanks in advance people
Here is the code:
public class ItemNameDialog extends DialogFragment {
@Override
public Dialog onCreateDialog(final Bundle bundle) {
System.out.println("ON CREATE DIALOG WAS CALLED"); //This appears on LogCat, so this method is called.. the problem is not that
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
builder.setTitle("Configure an item to count:");
LayoutInflater inflater = getActivity().getLayoutInflater();
View view = inflater.inflate(R.layout.itempick_layout, null);
builder.setView(view);
final CheckBox box = (CheckBox) view.findViewById(R.id.itemSenseCheckBox);
final EditText itemNameBox = (EditText) view.findViewById(R.id.itemNameText);
final Spinner spinner = (Spinner) view.findViewById(R.id.itemsDefault);
final int viewIDClicked = getArguments().getInt(clickableViewID);
final String actualName = getArguments().getString(actualNameItemView);
System.out.println("H - before: " + itemNameBox.getText().toString().length()); //it appears on logcat "H - before: 0"
itemNameBox.setText(actualName);
System.out.println("H - after: " + itemNameBox.getText().toString().length()); //it appears on logcat "H - before: 3" so why not changing ?
return builder.create();
}
}
My problem was that below that code, and before the method onCreateDialog ends, I had a few methods controlling a spinner.
The first item of that spinner has the purpose of "select nothing" and in that item choice I was just erasing the content of that edit text, like this:
@Override
public void onItemSelected(AdapterView<?> parent, View view,
int pos, long id) {
if(pos == 0){
if(editText.length() != 0 )
editText.setText("");
}
And I didnt know that while creating the spinner, it does trigger the event "onItemSelected" and because of that, the edittext was everytime erased, even when I didnt click on that item of the spinner..
So I managed to overcome this by a simple boolean. Every time the method onCreateDialog I put the boolean to true, and then my onItemSelected just operate when that bolean is false.
Like the code below:
@Override
public void onItemSelected(AdapterView<?> parent, View view, int pos, long id) {
if(firstGoingSpinner){
firstGoingSpinner = false;
}else{
if(pos == 0){
if(editText.length() != 0 )
editText.setText("");
}else{
editText.setText(""+parent.getItemAtPosition(pos));
Editable etext = editText.getText();
Selection.setSelection(etext, editText.length());
}
}
}
I hope this helps someone in the future ;)
