How can I remove all default padding from EditText?

问题

I am using an EditText and it always adds a bit of padding in my text to both left and right.
Adding android:includeFontPadding="false" did not help and using negative android:layout_marginLeft or android:layout_marginRight just makes the EditText "expand".
How can I strip all padding from the EditText that is being added by default?

<EditText
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:minHeight="20dp"
            android:fontFamily="roboto-regular"
            android:layout_gravity="center_vertical"
            android:gravity="center_vertical"
            android:layout_marginLeft="-5dp"
            android:layout_marginRight="-5dp"
            android:includeFontPadding="false"
            android:textSize="@dimen/size"
            android:textColor="@color/color"
            android:inputType="textCapWords"
            android:hint="@string/hint"
            android:editable="false"

            />

To remove the padding on the left and right of the EditText, you can use the following:

<EditText
    ...
    android:paddingLeft="0dp"
    android:paddingRight="0dp"
    ... />

If you also want to remove underline padding add negative margin:

<EditText
    ...
    android:layout_marginLeft="-4dp"
    android:layout_marginRight="-4dp"
    ... />
