Dagger2初步使用篇1

先上一个没有用Dragg2的例子：

eg; 1 public class User { 2 private String name; 3 4 public String getName() { 5 return name; 6 } 7 8 public void setName(String name) { 9 this.name = name; 10 } 11 } private void initData() { 2 3 User user = new User(); 4 5 user.setName(“测试”); 6 }

使用Drag2步骤

classpath ‘com.neenbedankt.gradle.plugins:android-apt:1.8’apply plugin: ‘com.neenbedankt.android-apt’ 3 compile ‘com.google.dagger:dagger:2.0.2’ apt ‘com.google.dagger:dagger-compiler:2.0.2’ compile ‘org.glassfish:javax.annotation:10.0-b28’ 4 package com.example.administrator.myplayerdemo.test;

import javax.inject.Inject;

import dagger.Module;

/** * Created by Administrator on 2017/3/10 0010. */ @Module public class Student { private int age;

public Student(int age, String name) { this.age= age; Name = name; }

@Inject public Student() { }

private String Name; public void SetName(String Name){ this.Name=Name; } public void SetAge(int age){ this.age=age; } public String getName(){ return this.Name; } public int getAge(){ return this.age; }

}

package com.example.administrator.myplayerdemo.test;

import android.app.Activity;

import com.example.administrator.myplayerdemo.activitys.MainListAct;

import javax.inject.Singleton;

import dagger.Component;

/** * Created by Administrator on 2017/3/10 0010. */

@Component public interface ActivityComponent { void inject(MainListAct MainListAct);//在哪个要用的界面绑定那个

} @Inject Student test; protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); DaggerActivityComponent.builder().build().inject(this); test.SetName(“haihang”); test.SetAge(20); Log.i(“gsc”,test.getName()); }
