Set Login/Logout Text for Button in Facebook Android SDK 4.0?

Just need change the attribute accordingly. Refer to : this

eg:

<com.facebook.login.widget.LoginButton        xmlns:facebook="http://schemas.android.com/apk/res-auto"        facebook:com_facebook_login_text="LOGIN"/>

use facebook:login_text and facebook:logout_text

 <com.facebook.widget.LoginButton            android:id="@+id/login_button"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:layout_marginTop="5dp"            facebook:confirm_logout="false"            facebook:fetch_user_info="true"            android:text="testing 123"            facebook:login_text="LOGIN"            facebook:logout_text="LOGOUT"            />

If the above doesnt work, try to add following in your values folder

<resources><string name="com_facebook_loginview_log_in_button">LOGIN</string><string name="com_facebook_loginview_log_out_button">LOGOUT</string></resources>

Update 2: Possible Solution

Override those strings in your strings.xml

<string name="com_facebook_loginview_log_out_button">Log out</string><string name="com_facebook_loginview_log_in_button">Log in</string><string name="com_facebook_loginview_log_in_button_long">Log in with Facebook</string>
