java.lang.IllegalStateException Butterknife

Question

I am facing java.lang.IllegalStateException Required view 'splash_text' but I have included it in the xml.

I am using Butterknife to Bind the views.

 compile 'com.jakewharton:butterknife:7.0.1'

Xml :

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@android:color/holo_orange_light">

<com.CustomTextView
    android:id="@+id/splash_text"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
   />

</RelativeLayout>

Activity :

@Bind(R.id.splash_text)
CustomTextView mSplashTv;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_splash);
    ButterKnife.bind(this);

    mSplashTv.setText("Splash");

    new Handler().postDelayed(new Runnable() {
        @Override
        public void run() {
            finishSplash();
        }
    },3000);
}

Application is crashing at the line mSplashTv.setText("Splash");

Log :

  Caused by: java.lang.IllegalStateException: Required view 'splash_text' with ID 2131492944 for field 'mSplashTv' was not found. If this view is optional add '@Nullable' annotation.

Update:

BaseActivity:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    ButterKnife.bind(this);
}

Support Library used:

 compile 'com.android.support:appcompat-v7:23.1.1'

Please post onCreate of BaseActivity. – Indecorous

Try removing ButterKnife.bind(this); from BaseActivity. – Indecorous

I tried. Still facing same issue. – Wigwag

Not sure but smell like support library dependency issue and show your base application – Cupreous

you are extending a base activity. Have you overridden setContentView in BaseActivity? Because anywhere if binding call comes before setContentView, it would fail. – Indecorous

Answer 1

Remove binding from base activity. When ButterKnife bind in base class, your layout not inflated yet.
Also you can add @Nullable annotation to field.

Adding the @Nullable to the field fixed the issue for me. – Kape

Answer 2

It's because your layout is not inflated yet. If you are using BaseActivity, do something like this :

public abstract class BaseActivity extends AppCompatActivity {

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        this.setContentView(this.getLayoutContentViewID());
        ButterKnife.bind(this); //Configure Butterknife
    }

    public abstract int getLayoutContentViewID();

}

Next, in your MainActivity :

public class MainActivity extends BaseActivity {

    @BindView(R.id.main_activity_coordinator_layout) CoordinatorLayout coordinatorLayout;

    ...

    @Override
    public int getLayoutContentViewID() { return R.layout.activity_main; }
    ...

}

Check your support Library version. I was getting the above error since i upgraded support library to 23 version. may be that is causing error.NavigationView get/find header layout
