Have added a Google Sign in and Facebook button as shown below
<com.google.android.gms.common.SignInButton
android:id="@+id/loginWithGPlusBtn"
android:layout_width="0dp"
android:layout_height="0dp"
app:layout_constraintHeight_percent="0.1"
android:layout_marginStart="8dp"
android:layout_marginTop="8dp"
android:layout_marginEnd="8dp"
android:layout_marginBottom="8dp"
android:scaleType="centerCrop"
app:layout_constraintBottom_toTopOf="@+id/loginWithFacebookBtn"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="@+id/raylImage"
app:srcCompat="@mipmap/ic_gp_login" />
<com.facebook.login.widget.LoginButton
android:id="@+id/loginWithFacebookBtn"
android:layout_width="0dp"
android:layout_height="0dp"
android:layout_marginStart="8dp"
android:layout_marginEnd="8dp"
android:layout_marginBottom="8dp"
android:scaleType="centerCrop"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintHeight_percent="0.1"
app:layout_constraintStart_toStartOf="parent" />
Now, although the G+ button shows up properly, with the text in the middle of the box, I have no such luck with FB. I can manually add a fixed padding like this: android:paddingTop="10dp" but this will take away the flexibility of positioning for different sized screens. Tried different settings, but no luck yet. Any ideas ?
