inputFilter for TextInputEditText

In my application I have an EditText.

This EditText is for currency input, for example: 2.23, 9.99

In other words user can type 2 then . then 23 to this EditText

To achieve this behavior of EditText I implemented an InputFilter like in Mussa's answer of this question EditText with Currency format. And it worked like a charm.

But then I wanted to replace my EditText by construction like this:

    <android.support.design.widget.TextInputLayout
        android:id="@+id/secondary_currency"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toBottomOf="@+id/main_currency"
        tools:hint="Болгарский перец">

        <android.support.design.widget.TextInputEditText
            android:id="@+id/secondary_currency_input"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:inputType="number"
            android:textSize="12sp"
            tools:text="348929.00" />
    </android.support.design.widget.TextInputLayout>

Now, I apply my InputFilter to the TextInputEditText.

I was surprised when I didn't manage to type . after 2.

Why I can't to type dot in case of TextInputEditText? How to achieve it?

With the current layout code. I can see that you have used inputType as number and your desirable has to be decimal.

You can try with inputType as numberDecimal.

Hope it helps.
