Question

我在一个片段中有一个相对的布局。该片段位于MainActivity内部。我想对其进行setonClickListener事件以打开一个新活动。我想进行相对布局rlLogOut来打开SignInActivity活动。但是如何将setOnClickListener事件放在片段上。是在OtherFragment.kt还是MainActivity中

我试图在MainActivity中制作setOnClickListener，但我知道那不是解决方案。我认为目的是问题。但是我不知道它的语法。我是科特林的新人。

import android.content.Intent
import android.os.Bundle
import android.support.v4.app.Fragment
import android.view.LayoutInflater
import android.view.View
import android.view.ViewGroup
import kotlinx.android.synthetic.main.fragment_others.*


// TODO: Rename parameter arguments, choose names that match
// the fragment initialization parameters, e.g. ARG_ITEM_NUMBER
private const val ARG_PARAM1 = "param1"
private const val ARG_PARAM2 = "param2"

/**
 * A simple [Fragment] subclass.
 *
 */
class OtherFragment : Fragment() {

override fun onCreateView(
    inflater: LayoutInflater, container: ViewGroup?,
    savedInstanceState: Bundle?

): View? {
    // Inflate the layout for this fragment
    rlLogOut.setOnClickListener{
        val mainIntent = Intent(
            this@OtherFrament,
            SignInActivity::class.java
        )
        startActivity(mainIntent)
    }
    return inflater.inflate(R.layout.fragment_others, container, false)
}
}

我希望单击rlLogOut会打开SignInActivity活动。感谢您的帮助。

  override fun onCreateView(
      inflater: LayoutInflater, 
      container: ViewGroup?,
      savedInstanceState: Bundle?
  ): View = inflater.inflate(R.layout.fragment_others, container, false)


  override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
      super.onViewCreated(view, savedInstanceState) 
      rlLogOut.setOnClickListener {
            val mainIntent = Intent(requireActivity(),  SignInActivity::class.java)
            requireActivity().startActivity(mainIntent)
      }    
  }

我无法在片段上设置ononClickListener RelativeLayout
