Butterknife: Include layout cannot bind views

[franciscerio]

I am using "include" layouts for my toolbar but i got NPE.

I have a BaseToolbarActivity which is initializing Butterknife.bind(this) and other stuffs.

• I bind my toolbar @Bind(R.id.toolbar) in BaseToobarActivity

In my SignupActivity extends BaseToolbarActivity, I need to set a toolbar title and other stuffs that is related to toolbar but here is the problem.

I always get NPE in toolbar.

This is my signup_activity.xml

<include
    android:id="@+id/toolbarContainer"
    layout="@layout/toolbar"></include>

<ScrollView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_below="@+id/toolbarContainer"
    android:layout_marginLeft="16dp"
    android:layout_marginRight="16dp"
    android:fillViewport="true"
    android:scrollbars="none">
</ScrollView>

and this is my toolbar.xml

<android.support.v7.widget.Toolbar
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/toolbar"
    android:layout_width="match_parent"
    android:layout_height="?android:attr/actionBarSize"
    android:background="@drawable/pager_bg"
    android:minHeight="?android:attr/actionBarSize"
    app:theme="@style/AppTheme"
    tools:ignore="MissingPrefix">

    <TextView
        android:id="@+id/tvToolbarTitle"
        fontPath="fonts/Roboto-Regular.ttf"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="left|center"
        android:text=""
        android:textAllCaps="true"
        android:textColor="@color/white"
        android:textSize="@dimen/text_font_size_toolbar_5"/>

</android.support.v7.widget.Toolbar>

I used this approach before but now i'm getting some errors.

This is the Log:
D/ButterKnife: Looking up view binder for com.do.de.ui.activity.SignupActivity
D/ButterKnife: HIT: Loaded view binder class.

Does it work for findViewById?

[andrey-shikhov]

The error is because in include tag id was redefined from toolbar to toolbarContainer so findViewById also will return null because no View with id="@id/toolbar" exists. So butterknife runs as designed.

Good eyes 👀

even i have similar Include tag in my code like above . If i want to declare toolbar using bindView in respective activity..which toolbar id should i need to consider and use it for toolbar initialisation.

In my case i have given toolbar id "hybrid_Act_toolbar" and include tag id also "hybrid_Act_toolbar" Getting below error:
as Caused by: java.lang.IllegalStateException: Required view 'hybrid_Act_toolbar' with ID 2131690576 for field 'hybrid_Act_toolbar' was not found. If this view is optional add '@Nullable' (fields) or '@Optional' (methods) annotation.
