Android: Clear keyboard input when edittext is cleared

Question

I want to set an automatic thousand separator to my edittext. I did it with an textwatcher. In

public void afterTextChanged(Editable s)

i save the current value of my edittext, format it with

@Override
        public void afterTextChanged(Editable s) {

            InputField.this.removeTextChangedListener(this);
            double tmp = getDoubleValue();

            s.clear();
s.append(DecimalFormat.getInstance(Locale.GERMAN).format(tmp));

            InputField.this.addTextChangedListener(this);
        }

    });

But the Keyboard from my Galaxy Tab doesn't care If I clear the editable. It keeps the current input and fills the edittext with the complete number. A short example:

I type "1", the keyboard inserts "1", the edittext shows "1".
I type "2", the keyboard inserts "12", the edittext shows "112"
I type "3", the keyboard inserts "123", the edittext shows "112.123"
I press the delete button, the keyboard inserts "12", the edittext shows "11.212.312" I press the delete button again, the keyboard inserts "1", the edittext shows "112.123.121"

My question is: how can I disable this keyboardfeature? enter image description here

or how can I clean this keyboard "cache"?

If I use inputtype "numberDecimal", it works but I can't use points as thousand separators(but it is needed in germany), because they will be interpreted as decimal mark and there can only be one.

I am not sure if you can clean the cache, but how about disabling the suggestion bar.. you can do that programatically:

YourEditText.setInputType(YourEditText.getInputType()
| EditorInfo.TYPE_TEXT_FLAG_NO_SUGGESTIONS
| EditorInfo.TYPE_TEXT_VARIATION_FILTER);

or you can deactivate in your EditText XML tag.. you can set:

<EditText>
   android:inputType="textFilter
   .... />

you can use this value too but unfortunately it doesn't work in all devices specially HTC

android:inputType="textNoSuggestions"

Edit

Sometimes it doesn't work because it's up to the implementation of the keyboard to do the right thing including the Flags.. However, everything has a workaround can you try the following code in XML:

android:inputType="textNoSuggestions|textVisiblePassword"

or in Java:

yourEditText.setInputType(InputType.TYPE_TEXT_FLAG_NO_SUGGESTIONS | InputType.TYPE_TEXT_VARIATION_VISIBLE_PASSWORD);

and give me a feedback if it worked or not..

Thank you very much, InputType.TYPE_TEXT_FLAG_NO_SUGGESTIONS | InputType.TYPE_TEXT_VARIATION_VISIBLE_PASSWORD works for me :) – Ef Ge Apr 14 '14 at 09:45
