How to change the height of the 'Log in with Facebook' button?

问题

I already tried several answers I could find but none of them worked with the latest Facebook Android SDK version 4.0.

How can I change the layout height with the latest SDK?

回答1:

Just set paddingTop and paddingBottom. It works for me.

<com.facebook.login.widget.LoginButton
        android:id="@+id/login_facebook_button"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:paddingTop="15dp"
        android:paddingBottom="15dp"
        android:layout_marginRight="30dp"
        android:layout_marginLeft="30dp"/>

For Facebook SDK v4.x (or rather than using separate xml style or programmatically)

The height of button is decided by its padding and textSize.

So if you want to increase button size, do it something like this

<com.facebook.login.widget.LoginButton
xmlns:facebook="http://schemas.android.com/apk/res-auto"
facebook:com_facebook_login_text="Log in with Facebook"
android:id="@+id/login_button"
android:textSize="15sp"
android:paddingTop="15dp" <!--increase more until it matches ur requirement -->
android:paddingBottom="15dp">

Hope it helps!!

There is no need to create a custom LoginButton.

You can just change the LoginButton parameters programmatically as described here.
