Android Google plus login button style

As the website described there are 3 sized button

1. Icon only = SignInButton.SIZE_ICON_ONLY
2. Normal button = SignInButton.SIZE_STANDARD
3. Wide button = SignInButton.SIZE_WIDE

You can use it like this.

gSignInButton = (SignInButton) findViewById(R.id.sign_in_button);
gSignInButton.setOnClickListener(this);
gSignInButton.setEnabled(true);
gSignInButton.setSize(SignInButton.SIZE_WIDE);// wide button style

You can do it with XML by adding & using the app namespace (as they are custom attributes):

<com.google.android.gms.common.SignInButton
      xmlns:app="http://schemas.android.com/apk/res-auto"
      android:id="@+id/sign_in_button"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      app:buttonSize="wide"
      app:colorScheme="dark"
      />

Possible attributes values are:

• buttonSize: "wide", "icon_only" or "standard"(default)
• colorScheme: "dark", "light" & "auto"(default)

You can use the setSize method of the Signin button to update the size.

For example, in my activity's onCreate method:

    mSignInButton = (SignInButton) findViewById(R.id.sign_in_button);
    mSignInButton.setOnClickListener(this);
    mSignInButton.setSize(SignInButton.SIZE_WIDE);

will change the Sign-In button to be wide.

You can also just use ANY button that is appropriately branded by just using a Button and then using the activity as the button's click handler.
