集成 Butterknife 后未显示菜单项

Question

在我当前的 Android 项目中，我使用 Butterknife 库来绑定视图并为它们使用 onClick 注释。这一切即使在片段中也很有效，但现在我无法找到解决方案：在集成 ButterKnife 之前没有看到问题。现在菜单项和应用程序名称在我的应用程序中使用 Butterknife 后消失。我是 androidButterKnife 的新手。任何人都可以建议我如何处理这个？提前致谢。

    import android.support.design.widget.FloatingActionButton;
    import android.support.v4.view.MenuItemCompat;
    import android.support.v7.app.AlertDialog;

    import butterknife.ButterKnife;
    import butterknife.OnClick;

public class MainActivity extends AppCompatActivity implements SearchView.OnQueryTextListener {

    @BindView(R.id.search)
    MenuItem searchitem;


    @BindView(R.id.fab1)
    FloatingActionButton floatingActionButton;

   @BindColor(R.color.colorFolatingButton)
   int Floating_Button_Color;

    @BindView(R.id.toolbar)
    Toolbar toolbar;



    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        ButterKnife.bind(this);
        setSupportActionBar(toolbar);
    }
    @OnClick(R.id.fab1)
    public void  newForm (View view){
        AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
        builder.setTitle("Confirm");
        builder.setMessage("Are you sure?");

        builder.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                Intent intent = new Intent(getApplicationContext(),BuilderPage.class);
                startActivity(intent);
            }
        });


        builder.setNegativeButton("No", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                dialog.dismiss();
            }
        });

        AlertDialog alert = builder.create();
        alert.show();
    }



    // display menu incons from menu_main XML
    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.frontscreen, menu);
        MenuItem  searchitem = menu.findItem(R.id.search);
        SearchView searchView = (SearchView) MenuItemCompat.getActionView(searchitem);
        searchView.setOnQueryTextListener(this);

        return true;

    }

    @Override
    public boolean onQueryTextSubmit(String query) {
        return false;
    }

    @Override
    public boolean onQueryTextChange(String newText) {
        return false;
    }
}

还有我的菜单

<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item android:id="@+id/search"
    android:title="hint_search"
    android:icon="@drawable/ic_magnify"
    app:showAsAction="collapseActionView|ifRoom"
    app:actionViewClass="android.support.v7.widget.SearchView" />

解决了

//在projectGradle中编译这个

  classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'

//并在appGradle中

apply plugin: 'android-apt'

这可能是一个愚蠢的错误，但我很高兴我解决了它。
