How to add space to AutoCompleteTextView suggestion
I would like to add space when the user select text from the auto complete suggestions, so when he continue to type he will start from a new word.
I tried to do it using TextWatcher but I get IndexOutOfBoundsException .
Any suggestions?
the text watcher I used is:
private class AddSpaceTextWatcher implements TextWatcher{
boolean shouldAddSpace = false;
@Override
public void beforeTextChanged(CharSequence s, int start, int before, int count) {
}
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
if (count - before > 1) // check that the new input is not from the keyboard
shouldAddSpace = true;
}
@Override
public void afterTextChanged(Editable editable) {
if (shouldAddSpace) {
shouldAddSpace = false;
mAutoCompleteTextView.setText(" ");
}
}
}
The exception I get is:

For selecting multiple items, you can simply use MultiAutoCompleteTextView which is a subclass of AutoCompleteTextView specifically built for this purpose.
OR
If you just want to append a space at the end making only one item selectable than try this:
public void afterTextChanged(Editable editable) {
String text = editable.toString();
if (shouldAddSpace && text.length() > 0 && !text.endsWith(" ")) {
editable.append(' ');
}
}
Edit:
Once the space is appended, you can simply call mAutoCompleteTextView.showDropDown(); to bring up the drop down again with updated text.
I'm not sure if this would solve your problem, but mAutoCompleteTextView.setText(" "); would remove the text. So I would do this:
mAutoCompleteTextView.setText(mAutoCompleteTextView.getText().toString() + " ");
mAutoCompleteTextView.setText(" ");
此代码将文本视图文本设置为“” - 您想要的是现有文本和空间。
mAutoCompleteTextView.setText(mAutoCompleteTextView.getText().append(" "));
