在 Android 中使用 Butterknife

Question

我正在尝试在 Android 中使用 Butterknife，它似乎不起作用。你能指导我哪里做错了吗

我试图在 'OnClick' 里面放置一个调试点，但似乎没有。

Gradle 依赖项（应用程序）

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

activity_main.xml

   <LinearLayout
        android:id="@+id/action_container"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal"
        android:layout_below="@+id/fragment_container"
        android:weightSum="2">
        <Button
            android:id="@+id/btn_frg_one"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:text="Fragment One"/>
        <Button
            android:id="@+id/btn_frg_two"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:text="Frag Two"/>
    </LinearLayout>

MainActivity.java

@OnClick({R.id.btn_frg_one, R.id.btn_frg_two})
    public void addFrgToCon(View view){
        switch (view.getId()){
            case R.id.btn_frg_one:
                addFragment(new FOne());
                break;
            case R.id.btn_frg_two:
                addFragment(new FTwo());
                break;
        }
    }

    public void addFragment(Fragment fragment){
        FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
        transaction.replace(R.id.fragment_container, fragment);
        transaction.addToBackStack(null);
        transaction.commit();
    }

我想你忘了这个

ButterKnife.bind(this);
