[android] customize Android Facebook Login button

I want to customize the look of the Facebook login button which we get along with the Facebook sdk for android (facebook-android-sdk-3.0.1). I want a simple android button which has title "Login via Facebook". I could not find any documentation regarding that.

So if any one knows on how to do it in a simple way, please tell me or direct me on how to do it.

You can modifiy the login button like this

<com.facebook.widget.LoginButton
            xmlns:fb="http://schemas.android.com/apk/res-auto"
            android:id="@+id/login_button"
            android:layout_width="249dp"
            android:layout_height="45dp"
            android:layout_above="@+id/textView1"
            android:layout_centerHorizontal="true"
            android:layout_gravity="center_horizontal"
            android:layout_marginBottom="30dp"
            android:layout_marginTop="30dp"
            android:contentDescription="@string/login_desc"
            android:scaleType="centerInside"
            fb:login_text=""
            fb:logout_text="" />

And in code I defined the background resource :

final LoginButton button = (LoginButton) findViewById(R.id.login_button);
button.setBackgroundResource(R.drawable.facebook);

Proper and Cleanest way

After checking the answers below, it seems that they're kind of hacks that rely on editing the login button view to make it more suitable for your need.

Being in the same position, I've succeeded to customize the facebook login button efficiently.

<mehdi.sakout.fancybuttons.FancyButton
   android:id="@+id/facebook_login"
   android:layout_width="wrap_content"
   android:layout_height="45dp"
   android:paddingLeft="10dp"
   android:paddingRight="10dp"
   app:fb_radius="2dp"
   app:fb_iconPosition="left"
   app:fb_fontIconSize="20sp"
   app:fb_iconPaddingRight="10dp"
   app:fb_textSize="16sp"
   app:fb_text="Facebook Connect"
   app:fb_textColor="#ffffff"
   app:fb_defaultColor="#39579B"
   app:fb_focusColor="#6183d2"
   app:fb_fontIconResource="&#xf230;"
   android:layout_centerVertical="true"
   android:layout_centerHorizontal="true" />

and implement the onClickListener like so

FacebookLogin.setOnClickListener(new View.OnClickListener() {
   @Override
   public void onClick(View view) {
      if (AccessToken.getCurrentAccessToken() != null){
         mLoginManager.logOut();
      } else {
         mAccessTokenTracker.startTracking();
         mLoginManager.logInWithReadPermissions(MainActivity.this,              Arrays.asList("public_profile"));
      }
   }
});

Its a trick not a proper method.

• Create a Relative layout.
• Define your facebook_botton.
• Also define your custom design button.
• Overlap them.

<RelativeLayout android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center_horizontal"
    android:layout_marginTop="30dp">
    <com.facebook.login.widget.LoginButton
    xmlns:facebook="http://schemas.android.com/apk/res-auto"
    android:id="@+id/login_button"
    android:layout_width="300dp"
    android:layout_height="100dp"
    android:paddingTop="15dp"
    android:paddingBottom="15dp" />
    <LinearLayout
    android:id="@+id/llfbSignup"
    android:layout_width="300dp"
    android:layout_height="50dp"
    android:background="@drawable/facebook"
    android:layout_gravity="center_horizontal"
    android:orientation="horizontal">
    <ImageView
    android:layout_width="30dp"
    android:layout_height="30dp"
    android:src="@drawable/facbk"
    android:layout_gravity="center_vertical"
    android:layout_marginLeft="10dp" />
    <View
    android:layout_width="1dp"
    android:layout_height="match_parent"
    android:background="@color/fullGray"
    android:layout_marginLeft="10dp"/>
    <com.yadav.bookedup.fonts.GoutamBold
    android:layout_width="240dp"
    android:layout_height="50dp"
    android:text="Sign Up via Facebook"
    android:gravity="center"
    android:textColor="@color/white"
    android:textSize="18dp"
    android:layout_gravity="center_vertical"
    android:layout_marginLeft="10dp"/>
    </LinearLayout>
</RelativeLayout>

<FrameLayout
    android:id="@+id/FrameLayout1"
    android:layout_width="70dp"
    android:layout_height="70dp"
    android:layout_marginStart="132dp"
    android:layout_marginTop="12dp"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toBottomOf="@+id/logbu">


    <ImageView
        android:id="@+id/fb"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@drawable/fb"
        android:onClick="onClickFacebookButton"
        android:textAllCaps="false"
        android:textColor="#ffffff"
        android:textSize="22sp" />

    <com.facebook.login.widget.LoginButton

        android:alpha="0"  <!--***SOLUTION***-->
        android:id="@+id/buttonFacebookLogin"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:paddingTop="45sp"
        android:visibility="visible"
        app:com_facebook_login_text="Log in with Facebook" />

</FrameLayout>

The easiest way to customize the integrated facebook button for both java and kotlin

Customize com.facebook.widget.LoginButton

step:1 Creating a Framelayout.

step:2 To set com.facebook.widget.LoginButton

step:3 To set Textview with customizable.

<FrameLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    >
    <com.facebook.widget.LoginButton
        android:id="@+id/fbLogin"
        android:layout_width="match_parent"
        android:layout_height="50dp"
        android:contentDescription="@string/app_name"
        facebook:confirm_logout="false"
        facebook:fetch_user_info="true"
        facebook:login_text=""
        facebook:logout_text="" />

    <TextView
        android:id="@+id/tv_radio_setting_login"
        android:layout_width="match_parent"
        android:layout_height="50dp"
        android:layout_centerHorizontal="true"
        android:background="@drawable/drawable_radio_setting_loginbtn"
        android:gravity="center"
        android:padding="10dp"
        android:textColor="@android:color/white"
        android:textSize="18sp" />
</FrameLayout>

MUST REMEMBER

1> com.facebook.widget.LoginButton & TextView Height/Width Same

2> 1st declate com.facebook.widget.LoginButton then TextView

3> To perform login/logout using TextView's Click-Listener

In newer Facebook SDK, the login and logout text name is :

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

The best way I have found to do this, if you want to fully customize the button is to create a button, or any View you want (in my case it was a LinearLayout) and set an OnClickListener to that view, and call the following in the onClick event:

com.facebook.login.widget.LoginButton btn = new LoginButton(this);
btn.performClick();

This is very simple. Add a button in the layout file like

<Button
   android:layout_width="200dp"
   android:layout_height="wrap_content"
   android:text="Login with facebook"
   android:textColor="#ffff"
   android:layout_gravity="center"
   android:textStyle="bold"
   android:onClick="fbLogin"
   android:background="@color/colorPrimary"/>

And in the onClick place the LoginManager's registercallback() method Becuse the this method automatically executes.

  public void fbLogin(View view)
{
    LoginManager.getInstance().logInWithReadPermissions(this, Arrays.asList("user_photos", "email", "public_profile", "user_posts" , "AccessToken"));
    LoginManager.getInstance().logInWithPublishPermissions(this, Arrays.asList("publish_actions"));
    LoginManager.getInstance().registerCallback(callbackManager,
            new FacebookCallback<LoginResult>()
            {
                @Override
                public void onSuccess(LoginResult loginResult)
                {
                    // App code
                }

                @Override
                public void onCancel()
                {
                    // App code
                }

                @Override
                public void onError(FacebookException exception)
                {
                    // App code
                }
            });
}

In order to have completely custom facebook login button without using com.facebook.widget.LoginButton.

According to facebook sdk 4.x,

There new concept of login as from facebook

LoginManager and AccessToken - These new classes perform Facebook Login

So, Now you can access Facebook authentication without Facebook login button as

layout.xml

    <Button
            android:id="@+id/btn_fb_login"
            .../>

MainActivity.java

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        FacebookSdk.sdkInitialize(this.getApplicationContext());

        callbackManager = CallbackManager.Factory.create();

        LoginManager.getInstance().registerCallback(callbackManager,
                new FacebookCallback<LoginResult>() {
                    @Override
                    public void onSuccess(LoginResult loginResult) {
                        Log.d("Success", "Login");

                    }

                    @Override
                    public void onCancel() {
                        Toast.makeText(MainActivity.this, "Login Cancel", Toast.LENGTH_LONG).show();
                    }

                    @Override
                    public void onError(FacebookException exception) {
                        Toast.makeText(MainActivity.this, exception.getMessage(), Toast.LENGTH_LONG).show();
                    }
                });

        setContentView(R.layout.activity_main);

        Button btn_fb_login = (Button)findViewById(R.id.btn_fb_login);

        btn_fb_login.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                  LoginManager.getInstance().logInWithReadPermissions(MainActivity.this, Arrays.asList("public_profile", "user_friends"));
            }
        });

    }

@Override 
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    callbackManager.onActivityResult(requestCode, resultCode, data); 
}

 <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=""
            facebook:logout_text=""
            />

This worked for me. To change the facebook login button text.

1. Create custom facebook button and change visability on native facebook button:

   <LinearLayout
           android:layout_width="match_parent"
           android:layout_height="wrap_content"
           android:orientation="vertical">
   
       <Button
               android:id="@+id/facebookView"
               android:layout_width="300dp"
               android:layout_height="48dp"
               android:layout_gravity="center_horizontal"
               android:layout_marginBottom="12dp"
               android:background="@drawable/btn_frame"
               android:gravity="center"
               android:text="@string/Sign_in_facebook_button"
               android:textColor="@color/colorAccent" />
   
       <com.facebook.login.widget.LoginButton
               android:id="@+id/facebookButton"
               android:layout_width="match_parent"
               android:layout_height="match_parent"
               android:visibility="invisible"
               android:layout_marginBottom="12dp" />
   
    </LinearLayout>
   

2. Add listener to your fake button and simulate click:

   facebookView.setOnClickListener(this);
   @Override
   public void onClick(View v) {
       if (v.getId() == R.id.facebookView){
          facebookButton.performClick();
       }
   }
   

//call Facebook onclick on your customized button on click by the following

FacebookSdk.sdkInitialize(this.getApplicationContext());

        callbackManager = CallbackManager.Factory.create();

        LoginManager.getInstance().registerCallback(callbackManager,
                new FacebookCallback<LoginResult>() {
                    @Override
                    public void onSuccess(LoginResult loginResult) {
                        Log.d("Success", "Login");

                    }

                    @Override
                    public void onCancel() {
                        Toast.makeText(MainActivity.this, "Login Cancel", Toast.LENGTH_LONG).show();
                    }

                    @Override
                    public void onError(FacebookException exception) {
                        Toast.makeText(MainActivity.this, exception.getMessage(), Toast.LENGTH_LONG).show();
                    }
                });

        setContentView(R.layout.activity_main);

        Button mycustomizeedbutton=(Button)findViewById(R.id.mycustomizeedbutton);

        mycustomizeedbutton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {

                  LoginManager.getInstance().logInWithReadPermissions(this, Arrays.asList("public_profile", "user_friends"));
            }
        });

    }
