Kotlin中的片段 [英] Fragment in kotlin

问题描述

我被卡在了我的应用程序中，因为我必须用Kotlin中的导航抽屉做一个片段.任何人都可以帮忙吗?我在网络上搜索了很多东西，但还没有找到任何东西... 下面是我在主要活动中所做的两项，我也希望该片段中也存在.

i'm stuck in my application because i have to do a fragment with the navigation drawer in kotlin.. can anyone help? I have search a lot of things in web but i didn't find anything yet... Down here is two items that i have do in main activity and i want that is present in the fragment too.

override fun onNavigationItemSelected(item: MenuItem): Boolean {
    // Handle navigation view item clicks here.
    when (item.itemId) {
        R.id.home -> {

        }
        R.id.subjects -> {
            val intent = Intent(this, SubjectsActivity::class.java)
            startActivity(intent)
        }
    }

    drawer_layout.closeDrawer(GravityCompat.START)
    return true
}

推荐答案

您可以使用它用HomeFragment()替换框架 mainDisplayFrame应该替换为您的FrameID

You can use this to replace your frame with HomeFragment() mainDisplayFrame should be replace by your FrameID

var fragmentTransaction = supportFragmentManager.beginTransaction()
fragmentTransaction.replace(R.id.mainDisplayFrame,HomeFragment()).commit()
mDrawerLayout!!.closeDrawers()
