Android-Butterknife: Caused by: java.lang.IllegalStateException: Required view xxx was not found


Android-Butterknife: Caused by: java.lang.IllegalStateException: Required view xxx was not found



Android Studio 3.1,
Gradle 4.1,
Java 1.8,
Android 6.0,
ButterКnife 8.8.1



I try to use ButterKnife on android app. But I have a problem.



in build.gradle:


classpath 'com.android.tools.build:gradle:3.1.2'



in app/build.gradle:


implementation "com.jakewharton:butterknife:8.8.1"
kapt "com.jakewharton:butterknife-compiler:8.8.1"



Here my xml layout: offer_details_pdf.xml


<android.support.constraint.ConstraintLayout 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:layout_width="match_parent"
android:layout_height="match_parent">

<include
android:id="@+id/offerDetailsToolBarMainContainer"
layout="@layout/offer_details_top_container"
android:layout_width="0dp"
android:layout_height="56dp"/>

<TextView
android:id="@+id/noItemsTextView"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:text="@string/no_items"
android:visibility="gone"/>

</android.support.constraint.ConstraintLayout>



In my activity


public class OfferDetailsPdfActivity extends AppCompatActivity implements MyInterface {
@BindView(R.id.offerDetailsToolBarMainContainer)
ConstraintLayout offerDetailsToolBarMainContainer;
@BindView(R.id.noItemsTextView)
TextView noItemsTextView;

@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Bundle extras = getIntent().getExtras();
setContentView(R.layout.offer_details_pdf);
ButterKnife.bind(this);
}

// implment method of interface MyInterface
@Override
public void showTopAndBottomContainer() {
offerDetailsToolBarMainContainer.setVisibility(View.VISIBLE);
}

// implment method of interface MyInterface
@Override
public void showNoItems() {
noItemsTextView.setVisibility(View.VISIBLE);
}



Method showTopAndBottomContainer() success work. But method showNoItems() not.
I get error:


showTopAndBottomContainer()


showNoItems()

Why it's not working?





Why do you have and @Override above showNoItems() method? Also do you have in gradle: annotationProcessor 'com.jakewharton:butterknife-compiler:8.8.1'

@Override


showNoItems()


annotationProcessor 'com.jakewharton:butterknife-compiler:8.8.1'

@Yupi the @ override most likely comes from the MyInterface interface.

yes, showNoItems() is implement of interface MyInterface

You have to use the annotations on the fields not on any method. And I cannot find R.id.noItemsTextView in the XML. :/

R.id.noItemsTextView

There is no text view matching with id R.id.noItemsTextView in the XML.


R.id.noItemsTextView



You might have forgotten to apply the ButterKnife plugin. Go to your build.gradle file and below apply plugin: 'com.android.library' add this: apply plugin: 'com.jakewharton.butterknife'


apply plugin: 'com.android.library'


apply plugin: 'com.jakewharton.butterknife'





I get error: Plugin with id 'com.jakewharton.butterknife' not found.

Honestly it's best to read the installation guide on GitHub. You also need to include classpath 'com.jakewharton:butterknife-gradle-plugin:8.8.1' in your BuildScript. github.com/JakeWharton/butterknife#library-projects

classpath 'com.jakewharton:butterknife-gradle-plugin:8.8.1'





Unable to find method 'com.android.build.gradle.api.BaseVariant.getOutputs()Ljava/util/List;'. Possible causes for this unexpected error include:<ul><li>Gradle's dependency cache may be corrupt (this sometimes occurs after a network connection timeout.)

Yeah, did you google that error already?

Opening a url is failing in Swift breakpointing inside the callback and logging success shows false.

The problem is that now I am using dbeaver for mac and this guide is not working. I can go on until the moment that I select my result set like in the image below: exporting data set But once I go further in the process, in the last step I get: no query Note that in "source" it was suppose to show the query that originated the result set, but instead it says just "select. As a result it does't select my result or anything (besides being "successful"). Normally my query would show up there automatically and I couldn't find any option that corrects this problem in the menus. Please help me! Thanks. Aft...
