ActivityBus

ActivtyBus基于编译时注解，自动生成帮助类，实现Activity和Activityt之间，Activity和Fragment之间的一键数据传值,避免了重写模板代码，提高开发效率。

中文 | English

支持的传值类型

  • Base type : boolean,byte,char,short,int,long,float,double,String
  • Base array type : boolean[],byte[],char[],short[],int[],long[],float[],double[],String[]
  • Container : List,Set,Map
  • Serializable : 实现 Serializable 接口的所有实体

下载

dependencies {
    compile 'com.kingja.activitybus:activitybus:1.2.5'
    annotationProcessor 'com.kingja.activitybus:activitybus-compiler:1.2.5'
}

使用

在Activity间传值

第一步：添加注解

@RequestParam：在目标Activity的需要传值的成员变量上添加该注解。 @ActivityBus：如果你需要调用startActivityForResult()，在目标Activity 上添加该注解，并设置requestCode。

@ActivityBus(requestCode = 100)
public class TargetActivity extends AppCompatActivity {
    @RequestParam
    public int age;
    @RequestParam
    public String name;
    @RequestParam
    public Person person;
    ...
}
第二步：传递数据

编译以后，ActivityBus会自动生成代理类，如TargetActivityBus，名称格式为【目标Actiity】+Bus，就是说，把你的Activty变成了一辆公交车，可以带客了，乘客就是你要传输的数据。之后调用代理类的goActivity()传入所需的数据即可。

public class MainActivity extends AppCompatActivity {
    ...
    TargetActivityBus.goActivity(this,1,"Hello",new Person("Entity"));
    ...
}
第三步：在目标Activity中进行注册

在目标Activity中调用register()，相当于告诉公交车，我要到这来。乘客到这站就可以下车了。接下来你就可以对乘客do anything了。

@ActivityBus(requestCode = 100)
public class TargetActivity extends AppCompatActivity {
    @RequestParam
    public int age;
    @RequestParam
    public String name;
    @RequestParam
    public Person person;
...
@Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_second);
        ...
        TargetActivityBus.register(this);
        tv_name.setText("My name is"+name);
    }
...
}

Activty和Fragment间传值

在Fragment中使用更简单，只需要两步。

第一步：添加注解
public class TargetFragment extends Fragment {
    @RequestParam
    public int aInt;
    @RequestParam
    public String aString;
    ...
}
第二步：传递数据

调用Fragment代理类的newInstance()方法进行传值。

public class MainActivity extends AppCompatActivity {
    ...
    TargetFragment targetFragment = TargetFragmentBus.newInstance(1,"Hello");
    getSupportFragmentManager().beginTransaction().add(R.id.fl_fragment, targetFragment).commit();
    ...
}
