How to use very small size button (24dp) android

Issue

Iam designing a food ordering page, so i need to use small button to add the food on cart.The problem was when i giving 24dp width and height the button size reduces but i cant able to add the text("+" "-").

I have tried

android:minWidth="0dp"
android:minHeight="0dp"
style="?android:attr/negativeButtonText"

<android.support.design.button.MaterialButton
                android:id="@+id/incrementButtton"
                style="?android:attr/buttonStyleSmall"
                android:layout_width="24dp"
                android:layout_height="24dp"
                android:layout_gravity="center_vertical"
                android:gravity="center"
                android:minWidth="0dp"
                android:minHeight="0dp"
                android:text="+"
                android:textColor="@color/ash"
                android:textSize="@dimen/fm_food_price_text_size" />

I want to know how to set button 24dp and show "+" text. as like below image. In this image i used textView, so text is visibile. I want this by using button.

Solution

I have solved by using ImageButton instead of button.

<ImageButton
                android:id="@+id/incrementButtton"
                android:layout_width="24dp"
                android:layout_height="24dp"
                android:padding="8dp"
                android:layout_gravity="center"
                android:gravity="center"
                android:background="?attr/selectableItemBackgroundBorderless"
                android:src="@drawable/ic_minus_symbol"
                android:scaleType="centerInside"
             />

for ripple effect i used

android:background="?attr/selectableItemBackgroundBorderless"
