Q:

Replace Google Plus login button with custom image in android

I'm integrating Google Plus login in my application.
I want to change my login button image with my custom icon.
How to do that?

A:

Its simple, using guideline from Google+ Sign In, you can use simple Button
<Button
   android:id="@+id/button"
   android:layout_width="wrap_content"
   android:layout_height="wrap_content"
   android:layout_centerHorizontal="true"
   android:text="@string/common_signin_button_text_long" />

By setting onClickListener
 if (mGoogleApiClient.isConnected()) {
      Plus.AccountApi.clearDefaultAccount(mGoogleApiClient);
      mGoogleApiClient.disconnect();
      mGoogleApiClient.connect();
    }
