EditText value is reversed

Question

I've got an odd one. I'm trying to format some text while the user types into an EditText field. I am using the TextWatcher and responding to afterTextChanged event (code below). What is odd is after the first time this logic runs the text starts to become reversed. It seems that the Editable object contains the string backwards. Does anyone have any idea how to fix this?

_textWatcher = new TextWatcher()
                {
                    @Override
                    public void beforeTextChanged(CharSequence charSequence, int i, int i2, int i3)
                    {
                    }

                    @Override
                    public void onTextChanged(CharSequence charSequence, int i, int i2, int i3)
                    {
                    }

                    @Override
                    public void afterTextChanged(Editable editable)
                    {
                        Editable e = textView.getText();
                        String text = e.toString();

                        logger.d("[FormListAdapter][addTextChangedListener] Format Text: " + text);

                        Number numVal = FormFieldBusiness.ConvertStringToNumber(text, formField.GetFormFieldType());
                        String fText = FormFieldBusiness.GetFormattedValue(numVal, formField.GetFormFieldType());

                        editText.removeTextChangedListener(_textWatcher);
                        textView.setText(text);
                        editText.addTextChangedListener(_textWatcher);
                    }
                };

                editText.addTextChangedListener(_textWatcher);

* UPDATE *

In an attempt to help anyone out there who's looking at this here is my XML layout file.

As I mentioned before the text is correct until after the first the time setText method is called. After that the Editable object is reversed.

Answer 1

The issue is you are setting the text in the EditText field (even though you have removed the listener) you are listening for. this is causing the cursor to move to the beginning of the line, therefore making it type backwards

try changing from a TextWatcher to TextView.OnEditorActionListener and listen for the action key set on the EditText so when they hit the action key, it does your desired functionality.

add

android:imeOptions="actionDone"

to your button xml and assign it with

TextView.OnEditorActionListener editingActionListener = new TextView.OnEditorActionListener() {
    @Override
    public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
        if ((actionId == EditorInfo.IME_NULL && event.getAction() == KeyEvent.ACTION_DOWN) || actionId == EditorInfo.IME_ACTION_DONE) {
            //do stuff where you set the text here
        }
        return true;
    }
};
editText.setOnEditorActionListener(editingActionListener);

alternatively, you can use OnFocusChangeListener

View.OnFocusChangeListener focusChangeListener = new View.OnFocusChangeListener() {
    @Override
    public void onFocusChange(View v, boolean hasFocus) {
        if (v.getClass().equals(EditText.class)) {
            if (!hasFocus) {
                //do your stuff here
            }
        }
    }
};
editText.setOnFocusChangeListener(focusChangeListener);

Answer 2

Simply move the cursor to the correct position in your TextWatcher after setting the EditText content:

@Override
public void afterTextChanged(Editable editable)
{
    ...
    int position = editText.getSelectionStart();
    editText.setText(text);
    editText.setSelection(position);
    ...
}
