android - 使用butterknife,不能编译通过

Question

package com.aa.safe.safehei.activities;

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.TextView;

import com.aa.safe.safe.R;

import butterknife.BindView;
import butterknife.ButterKnife;
import butterknife.OnClick;

public class DogActivity extends AppCompatActivity {


    @BindView(R.id.tv_islocked_notselect)
    TextView mTvIslockedNotselect;
    @BindView(R.id.tv_islocked_select)
    TextView mTvIslockedSelect;

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

}

使用butterknife后
在app/build/generated/source/apt/debug/包名/DogActivity$$ViewBinder
下提示报错

import butterknife.internal.Finder;
import butterknife.internal.ViewBinder;

提示这二个类找不到,我看了下的确是没有的

messages 窗口也提示找不到符号........

    @Bind(R.id.drawer_layout)
    DrawerLayout drawerLayout;
    @Bind(R.id.nav_view)
    NavigationView navigationView;
    @Bind(R.id.toolbar)
    Toolbar toolbar;
    @Bind(R.id.main_container)
    FrameLayout mainContainer;
    ActionBarDrawerToggle mActionBarDrawerToggle;
    FragmentManager fragmentManager;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        ButterKnife.bind(this);
        ···
        }

What version are you using? This is 7.0.1

compile 'com.jakewharton:butterknife:7.0.1'

Answer 2

butterknife cannot be used in the library project, I don’t know if this is the case for you,

Answer 3

The 8.1.0 version I use needs to add apt 'com.jakewharton:butterknife-compiler:8.1.0'
in gradle. It is used for pre-compilation. I don’t know if it is required for 7.0
