Custom Button Always Too Big

I am trying to create a custom button with its shape being as similar as possible to the one of the Android default button. The problem is, no matter how much I reduce the height,

Solution 1:

when you set any Background to A Button its hight will increase check below test cases

• when you set both button background the button size are same

Try this you also need to set android:background to your default button like this

<LinearLayoutandroid:layout_width="match_parent"android:layout_height="wrap_content"android:orientation="horizontal"><Buttonandroid:id="@+id/button"android:layout_width="wrap_content"android:layout_height="48dp"android:background="@drawable/demo"android:text="custom"
        /><Buttonandroid:id="@+id/button3"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_marginLeft="8dp"android:background="@color/colorAccent"android:text="default"
         /></LinearLayout>

OUTPUT

without setting custom background to your custom button

<LinearLayoutandroid:layout_width="match_parent"android:layout_height="wrap_content"android:orientation="horizontal"><Buttonandroid:id="@+id/button"android:layout_width="wrap_content"android:layout_height="48dp"android:text="custom"
        /><Buttonandroid:id="@+id/button3"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_marginLeft="8dp"android:background="@color/colorAccent"android:text="default"
         /></LinearLayout>

Output

EDITAndroid Button has default padding.

check the default Size of button

<LinearLayoutandroid:layout_width="match_parent"android:layout_height="wrap_content"android:orientation="horizontal"><Buttonandroid:id="@+id/button"android:layout_width="wrap_content"android:layout_height="48dp"android:background="@drawable/demo"android:text="custom"
        /><Buttonandroid:id="@+id/button3"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_marginLeft="8dp"android:text="default"
         /></LinearLayout>

OUTPUT

Solution 2:

Android Button has default padding.

When I set android:background="@android:color/holo_blue_bright" in the Button. It will be the same of custom Button .

 <Button
    android:id="@+id/button3"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginLeft="8dp"
    android:text="default"
    android:background="@android:color/holo_blue_bright"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintLeft_toRightOf="@+id/button"
    app:layout_constraintTop_toTopOf="parent"
    app:layout_constraintVertical_bias="0.501" />

Output
