使用 kotlin 自定义片段转换

Question

你知道如何使用 kotlin 将自定义过渡动画注入到下面的 replaceFragment() 方法吗？它是一个片段到片段的过渡

  private inline fun FragmentManager.inTransaction(func: FragmentTransaction.() -> FragmentTransaction) {
        beginTransaction().func().commit()
    }

    private fun addFragment(fragment: Fragment, frameId: Int) {
        supportFragmentManager.inTransaction { add(frameId, fragment) }
    }

    public fun replaceFragment(fragment: Fragment, frameId: Int) {
        supportFragmentManager
                .inTransaction { replace(frameId, fragment) 
    }

找到解决方案：

private inline fun FragmentManager.inTransaction(func: FragmentTransaction.() -> FragmentTransaction) {
        beginTransaction()
                .func()
                .setCustomAnimations()
                .commit()
    }
