Using custom login button with Twitter Fabric?

You can achieve this by using TwitterAuthClient. i.e,

First of all create normal button like,

<Button      android:id:"@+id/twitter_custom_button"      ...  />

Now, in you java class file use TwitterAuthClient instead of TwitterLoginButton. then set your CallBack inside Button's onClick

TwitterAuthClient mTwitterAuthClient= new TwitterAuthClient();Button twitter_custom_button = (Button) findViewById(R.id.twitter_custom_button);twitter_custom_button.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {             mTwitterAuthClient.authorize(this, new com.twitter.sdk.android.core.Callback<TwitterSession>() {                       @Override                       public void success(Result<TwitterSession> twitterSessionResult) {                           // Success                       }                       @Override                       public void failure(TwitterException e) {                           e.printStackTrace();                       }            });        }});@Overrideprotected void onActivityResult(int requestCode, int responseCode, Intent intent) {    mTwitterAuthClient.onActivityResult(requestCode, responseCode, intent);}

Well actually there's a way of doing this

 private TwitterAuthClient client;@Overrideprotected void onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    setContentView(R.layout.activity_login);    TwitterAuthConfig authConfig = new TwitterAuthConfig(TWITTER_KEY, TWITTER_SECRET);    Fabric.with(this, new Twitter(authConfig));    client = new TwitterAuthClient();    Button customLoginButton = (Button) findViewById(R.id.custom_twitter_login);    customLoginButton.setOnClickListener(new View.OnClickListener() {        @Override        public void onClick(View v) {            client.authorize(LoginActivity.this, new Callback<TwitterSession>() {                @Override                public void success(Result<TwitterSession> twitterSessionResult) {                    Toast.makeText(LoginActivity.this, "success", Toast.LENGTH_SHORT).show();                }                @Override                public void failure(TwitterException e) {                    Toast.makeText(LoginActivity.this, "failure", Toast.LENGTH_SHORT).show();                }            });        }    });}@Overrideprotected void onActivityResult(int requestCode, int resultCode, Intent data) {    super.onActivityResult(requestCode, resultCode, data);    client.onActivityResult(requestCode, resultCode, data);}

Be aware, onActivityResult part is very important, you seem to lost it.

here's my xml:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"android:layout_width="match_parent"android:layout_height="match_parent"><Button    android:id="@+id/custom_twitter_login"    android:layout_width="match_parent"    android:layout_height="wrap_content"    android:layout_marginTop="@dimen/padding_medium"    android:text="@string/twitter_login"/>

Since Fabric doesn't allow theming yet, we should assume that we'll have to write potentially throw away code to get this to work. As such, I prefer less code to more code when I know I won't be keeping it.

Luis's solution will work fine, but my UI was done, with a button already, and I just wanted that button to work. Here's how I accomplished this.

Drop in the TwitterLoginButton, as requested by the Fabric wizard, but set it to visibility: gone

 <com.twitter.sdk.android.core.identity.TwitterLoginButton    android:id="@+id/twitter_login_button"    android:layout_width="wrap_content"    android:layout_height="wrap_content"    android:layout_centerInParent="true"    android:visibility="gone" />

Pull the reference of the loginButton in your Activity (also part of Fabric setup - nothing new here):

loginButton = (TwitterLoginButton) findViewById(R.id.twitter_login_button);

Finally, for my existing button, I added a click listener, which simply delegated the click event over to the twitter login button.

myLoginButton.setOnClickListener(new View.OnClickListener() {        @Override        public void onClick(View v) {            loginButton.performClick();        }    });

Worked like a charm.
