Kotlin开发遇到的问题

1，kotlinx.android.synthetic遇到的坑

循环addView(itemView) adapter中

都只正确初始化了第一个item, 不用这个就正常

当从后台返回前台时

当从后台返回前台时Kotlin莫名会闪退
override fun setLayout() {
TODO("not implemented") //To change body of created functions use File | Settings | File Templates.
}
kotlin.NotImplementedError: An operation is not implemented: not implemented

2，Kotlin与Butteknife兼容性

用kotterknife.bindView代替

    private inner class SearchViewTextListener(var emitter: ObservableEmitter<String>) : SearchView.OnQueryTextListener {
        override fun onQueryTextChange(newText: String?): Boolean {

            newText?.let { emitter.onNext(it) }
            return false
        }

        override fun onQueryTextSubmit(query: String?): Boolean {
            query?.let { emitter.onNext(it) }
            return false
        }
    }

        Observable.create(ObservableOnSubscribe<String> { e ->
            val listener = SearchViewTextListener(e)
            searchView.setOnQueryTextListener(listener)
        })
                .debounce(300, TimeUnit.MILLISECONDS)
                .filter { t -> t.isNotEmpty() }
                .switchMap { query ->
                    Observable.create(ObservableOnSubscribe<EventPickSearchResult> { observableEmitter ->
