ButterKnife onclick is not working

Question

I injected views perfectly using butterknife library. But when I try to implement listeners, for example onclick I'm not able to implement them. Following java code will help you to understand my problem.

Java code:

public class LoginActivity extends ActionBarActivity{     @InjectView(R.id.toolbar) Toolbar toolbar;     @InjectView(R.id.btn_login) Button login;     @Override     protected void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstanceState);         setContentView(R.layout.login);         ButterKnife.inject(this);          initialize();         //initListeners();          @OnClick(R.id.btn_login)         public void submit(View view) {           // TODO submit data to server...         }     }      /*private void initListeners() {         @OnClick(R.id.btn_login)         public void login(){          }     }*/      private void initialize() {         setSupportActionBar(toolbar);         getSupportActionBar().setIcon(R.drawable.toolbar_icon);         getSupportActionBar().setTitle(null);         getSupportActionBar().setDisplayShowHomeEnabled(true);     } } 

Tell me why it is happening. Anything wrong in code? I've already configured the IDE which is compatible with ButterKnife by using following URL.

MainActivity.java

import android.os.Bundle; import android.support.v7.app.ActionBarActivity; import android.view.View; import android.widget.Button; import android.widget.Toast;  import butterknife.ButterKnife; import butterknife.InjectView; import butterknife.OnClick;   public class MainActivity extends ActionBarActivity {       @InjectView(R.id.button)     Button login;      @Override     protected void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstanceState);         setContentView(R.layout.activity_main);         ButterKnife.inject(this);       }       @OnClick(R.id.button)     void submitButton(View view) {             Toast.makeText(this, "Click", Toast.LENGTH_SHORT).show();     } } 

and the activity_main.xml part

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:tools="http://schemas.android.com/tools"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:paddingLeft="@dimen/activity_horizontal_margin"     android:paddingRight="@dimen/activity_horizontal_margin"     android:paddingTop="@dimen/activity_vertical_margin"     android:paddingBottom="@dimen/activity_vertical_margin"     tools:context=".MainActivity">       <Button         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:text="New Button"         android:id="@+id/button"         android:layout_alignParentTop="true"         android:layout_alignParentLeft="true"         android:layout_alignParentStart="true"         android:layout_marginLeft="59dp"         android:layout_marginStart="59dp"         android:layout_marginTop="132dp"         /> </RelativeLayout> 

in build.gradle file(app)

dependencies {     compile fileTree(dir: 'libs', include: ['*.jar'])     compile 'com.android.support:appcompat-v7:22.0.0'     compile 'com.jakewharton:butterknife:6.1.0' }
