Android 框架引用之EventBus、ButterKnife、Glide

一：Glide

build.gradle

dependencies{

implementation 'org.greenrobot:eventbus:3.1.1' //eventBus

implementation 'com.github.bumptech.glide:glide:4.7.1'

implementation "com.jakewharton:butterknife:${BUTTERKNIFE_VERSION}" //butter knife

annotationProcessor "com.jakewharton:butterknife-compiler:${BUTTERKNIFE_VERSION}"

}

Glide.with(this).load(url).into(mainBinding.imgOne);

int resourseId = R.mipmap.classinfo_honour;
Glide.with(this).load(resourseId).into(mainBinding.imgTwo);

RequestOptions requestOptions = new RequestOptions();
requestOptions.placeholder(R.mipmap.ic_launcher);
Glide.with(this).load(resourseId).apply(requestOptions).into(mainBinding.imgTwo);


二：EventBus

//配置见dependencies

//接收数据页面，注册EventBus

@Override
protected void onCreate(Bundle savedInstanceState) {

　　if (!EventBus.getDefault().isRegistered(this)) {
    　　EventBus.getDefault().register(this);//注册
　　}

}

@Subscribe(threadMode = ThreadMode.MAIN)
public void onEventMessage(EventTeacher eventTeacher) {
    TeacherBean teacherBean = eventTeacher.teacherBean;
    mainBinding.setTeacher(teacherBean);
}

@Override
protected void onDestroy() {
    super.onDestroy();
    EventBus.getDefault().unregister(this);//取消注册
}
//发送数据页面

TeacherBean teacherBean1 = new TeacherBean();
teacherBean.name = "w先生";
teacherBean.birthday = "2019-07-13";
EventBus.getDefault().post(new EventTeacher(teacherBean1));

//事件方法

public class EventTeacher {
    public TeacherBean teacherBean;

    public EventTeacher(TeacherBean teacherBean) {
        this.teacherBean = teacherBean;
    }
}

三:注解框架工具 butterknife
//配置见dependencies

在使用前，我们再添加一个自动生成代码的插件：zelezny

File->settings->Plugins

 

 

省略findViewById：

1 在activity 中：现在layout中写好控件和id，然后到对应的Activity中右击鼠标：

（或者alt+insert），鼠标的光标一定要在setContentView中的layout后面
