kotlin-targetFun

TargetFun是一个基于Kotlin语言的安卓开发库，其主要目的是为了让开发者更简单的使用安卓SDK及部分第三方Lib中的多函数接口。

使用本库后，你可以这样为EditText添加监听文本变化的接口：

EditText(this).withTextChangedListener {
        ifTextChanged { s, start, before, count ->
            //do sth
        }
}

或者这样

EditText(this).withTextChangedListener {
            ifBeforeTextChanged { s, start, count, after ->
                //do sth
            }
            ifTextChanged { s, start, before, count ->
                //do sth
            }
}

或者这样

EditText(this).withTextChangedListener {
        ifTextChanged { s, start, before, count ->
            //do sth
        }
        ifAfterTextChanged {
            //do sth
        }
}

或者如果项目中用到了Rxjava，可以这样用Observer:

Observable.just("1", "2", "3")
            .withSubscribe {
                ifNext {
                    //do sth
                }
            }

或者这样

Observable.just("1","2","3")
            .withSubscribe {
                ifNext {
                    //do sth
                }
                ifError {
                    //do sth
                }
            }

或者这样

Observable.just("1","2","3")
            .withSubscribe {
                ifNext {
                    //do sth
                }
                ifComplete {
                    //do sth
                }
            }

在kotlin中用过rxjava的应该知道，subscribe时虽然官方给了些lamada表达式快捷使用，但顺序和随机使用方法确实个令人困扰的问题，故有本方案。

目前版本支持的多函数接口如下

  • TextWatcher
  • ViewPager.OnPageChangeListener
  • Animator.AnimatorListener
  • AbsListView.OnScrollListener
  • RecyclerView.OnScrollListener
  • SeekBar.OnSeekBarChangeListener
  • View.OnAttachStateChangeListener
  • DrawerLayout.DrawerListener
  • View.OnClickListener（filter)
  • Observer (rx)
  • FlowableSubscriber (rx)
  • 一些彩蛋(๑◡๑)

Setup

repositories {
	 jcenter()
}

dependencies {
 	implementation "com.cysion:targetfun:1.2.0"
}

android studio 新版本默认 buildToolsVersion默认 28.0.2

using TargetFun

本库目的既然是基于原SDK接口的优化使用，自然用法跟原接口特别相似， 最明显的差别就是所有的设置接口方法都是以 'with'开头，{}内的方法以if开头

彩蛋

Edittext的扩展函数，打开/关闭键盘

EditText(this).openKeyBoard()

EditText(this).hideKeyBoard()

过滤频繁点击

Button(this).clickWithLimit {
	}

跳转Activity,1000请求码

gotoActivityForResult<EditExActivity>(1000)

gotoActivity<EditExActivity>()

str(resid), drawable(resid)等方法

TextView(this).text=str(R.string.app_name)

待补充...
