How to do Facebook Login with Custom Button Android

In my previous Facebook Post(http://androidammy.blogspot.in/2015/07/facebooklogin1.html). I write how to use Facebook default button to login with Facebook.

In this blog I am writing about how we can use facebook login functionality from android widget like Button/TextView/ImageView. All the steps are same as last facebook login post. This blog describe that  how to create instance of CallBackManager and LoginManager and how to call Login from click listener.

1.  Create Instance of LoginManager and CallbackManager.

com.facebook.login.LoginManager fbLoginManager;
        
        fbLoginManager = com.facebook.login.LoginManager.getInstance();
        CallbackManager callbackManager = CallbackManager.Factory.create();
        mFbLoginManager.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
            @Override
            public void onSuccess(LoginResult loginResult) {
              // here write code When Login successfully 
            }

            @Override
            public void onCancel() {
                
            }

            @Override
            public void onError(FacebookException e) {
                // here write code when get error
            }
        });

2. Call loginWithReadPermission method of LoginManager class from clickListener of android widget, Like 

    buttonFbLogin.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                mFbLoginManager.logInWithReadPermissions(LoginActivity.this, Arrays.asList("email", "public_profile", "user_birthday"));
            }
        });

All Done.
Happy Coding.
