EditText: Toggle InputType.TYPE_TEXT_FLAG_NO_SUGGESTIONS

I've created a custom EditText by extending android.widget.EditText.

I would like to have the auto correct spans only visible, when the EditText has focus. So I call setInputType(INPUT_NO_FOCUS); in the constructor and:

@Override
protected void onFocusChanged(boolean focused, int direction, Rect previouslyFocusedRect) {
    super.onFocusChanged(focused, direction, previouslyFocusedRect);
    if (focused) {
        setInputType(INPUT_FOCUS);
    } else {
        setInputType(INPUT_NO_FOCUS);
    }
}

with:

private final int INPUT_NO_FOCUS = TYPE_CLASS_TEXT | InputType.TYPE_TEXT_FLAG_MULTI_LINE
        | InputType.TYPE_TEXT_FLAG_NO_SUGGESTIONS;
private final int INPUT_FOCUS = TYPE_CLASS_TEXT | TYPE_TEXT_FLAG_MULTI_LINE
        | InputType.TYPE_TEXT_FLAG_AUTO_CORRECT | InputType.TYPE_TEXT_FLAG_AUTO_COMPLET;

==> There is indeed no auto correction and auto complete, but it does not appear after clicking on the EditText. Input type is changed successfully.

How can I trigger the auto correction/ add auto completion?

//Edit:

User Case I want to archive:

  1. MyEditText extends EditText view is displayed and not focused. There is no spell checking on the text (--> No red spans/lines under the text)

  2. User clicks into the edit field to. --> Spell checking gets triggered --> Red lines appear (User can click on wrong spelled words and let the OS correct them)

  3. User clicks on another View element --> Red lines/spans disappear.

Override this method in MyEditText class 

@Override
    protected void onTextChanged(CharSequence text, int start, int lengthBefore, int lengthAfter) {
        super.onTextChanged(text, start, lengthBefore, lengthAfter);
        setInputType(INPUT_FOCUS);
    }

Using this method you can change the inputType of EditText to INPUT_FOCUS that show red line under text when user edit text of MyEditText

I'm afraid there's no good way to do this. The problem is that the Android framework doesn't really have a mechanism to tell the keyboard when the input type has changed. A keyboard generally checks the type when the field opens. After that, if the type changes it won't know unless it polls for it, and I don't think any existing keyboard does that.
