First Blood

  • 给Activity添加注解:

    @Params(
        Val("intParam", Int::class),
        Val("booleanParam", Boolean::class),
        Val("stringParam", String::class)
    )
    open class TestActivity : AppCompatActivity() 
    

    通过Params注解, 告诉该Activity需要的参数类型及参数名称.

    例如TestActivity的参数分别为:

    • intParam :Int类型
    • booleanParam :Boolean类型
    • stringParam :String参数
  • 传递参数给Activity:

    Params注解编译之后,将会生成该Activity对应的Director文件,命名规则为 Activity名称+Director后缀,
    例如上面的TestActivity将会生成TestActivityDirector文件.

    btn_activity.setOnClickListener {
        //通过Director安全快速传递参数给TestActivity
        TestActivityDirector.of(this)
            .intParam(1123123123)
            .booleanParam(true)
            .stringParam("This is string param")
            .direct()
    }
    
  • 获取传递给Activity的参数:

    Params注解编译之后, 除了会生成Director文件, 还会生成对应的Params文件, 命名规则为 Activity名称+ Params后缀,
    例如上面的TestActivity将会生成TestActivityParams文件.

    class TestActivity : AppCompatActivity() {
    
        override fun onCreate(savedInstanceState: Bundle?) {
            super.onCreate(savedInstanceState)
            setContentView(R.layout.activity_test)
    
            //获取params参数
            val params = TestActivityParams.of(this)
          
            Log.d("TAG", params.intParam.toString())
            Log.d("TAG", params.booleanParam.toString())
            Log.d("TAG", params.stringParam)
        }
    }
    

Double Kill

接下来尝试给Fragment传递参数.

  • 添加Params注解:

    @Params(
        Val("intParam", Int::class),
        Val("booleanParam", Boolean::class),
        Val("stringParam", String::class)
    )
    class TestFragment : Fragment()
    
  • 传递参数给Fragment:

    同样的,Params注解编译之后,将会生成该Fragment对应的Director文件,命名规则为 Fragment名称+Director后缀,
    例如上面的TestFragment将会生成TestFragmentDirector文件.

    btn_fragment.setOnClickListener {
          TestFragmentDirector.of()
              .intParam(1123123123)
              .booleanParam(true)
              .stringParam("This is string param")
              .direct {
                  val fragmentTransaction = supportFragmentManager.beginTransaction()
                  fragmentTransaction.add(R.id.fragment_container, it)
                  fragmentTransaction.commit()
          }
    }
    
  • 获取传递给Fragment的参数:

    Params注解编译之后, 除了会生成Director文件, 还会生成对应的Params文件, 命名规则为 Fragment名称+ Params后缀,
    例如上面的TestFragment将会生成TestFragmentParams文件.

    class TestFragment : Fragment() {
    
        override fun onCreate(savedInstanceState: Bundle?) {
            super.onCreate(savedInstanceState)
            val params = TestFragmentParams.of(this)
          
            Log.d("TAG", params.intParam.toString())
            Log.d("TAG", params.booleanParam.toString())
            Log.d("TAG", params.stringParam)
        }
    }
    

Triple Kill

传递自定义数据类型

除了上述基本数据类型外,还支持自定义的数据类型.

  • 添加自定义类型参数:

    //自定义数据类型    
    class CustomEntity(
        val id: Int,
        val content: String
    )
    
    //使用自定义数据类型  
    @Params(
        Val("customParam", CustomEntity::class)
    )
    class TestActivity : AppCompatActivity() 
    
  • 传递自定义类型参数:

    btn_activity.setOnClickListener {
        TestActivityDirector.of(this)
            .customParam(CustomEntity(123, "Custom entity content"))
            .direct()
    }
    

自定义数据类型默认使用Gson进行序列化和反序列化, 因此请在release环境中Keep自定义的数据类型, 以免发生问题!

Ultra Kill

利用MutableParams注解生成 var 类型参数.

如上所见, 通过Params注解只能定义val不可变类型的参数, 要想定义var可变类型的参数, 可以通过
MutableParamsVar声明可变类型的参数.

例如:

@Params(
    Val("charParam", Char::class),
    Val("booleanParam", Boolean::class),
    Val("stringParam", String::class)
)
@MutableParams(
    Var("test", String::class),
    Var("test1", Boolean::class)
)
class TestActivity : AppCompatActivity()
