如何对不在"活动"中的片段执行setOnClickListener

Question

我在这里展示了3个片段，它们有一个id为omitir_swipe的TextView，我需要在展示这3个片段的活动中使用它，我该如何实现？：

3个片段xml:

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:background="@color/colorWhite"
>
<ImageView
android:id="@+id/image_swipe"
android:layout_width="200dp"
android:layout_height="200dp"
android:src="@drawable/books_swipe"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintHorizontal_bias="0.246"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintVertical_bias="0.329"
/>
<TextView
android:id="@+id/textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginBottom="116dp"
android:text="Amantium irae amoris integratio est."
android:textAlignment="center"
android:textColor="@color/colorBlack"
android:textSize="16dp"
android:textStyle="bold"
app:layout_constraintBottom_toTopOf="@+id/image_swipe"
app:layout_constraintEnd_toEndOf="@+id/image_swipe"
app:layout_constraintHorizontal_bias="0.465"
app:layout_constraintStart_toStartOf="@+id/image_swipe" />
<TextView
android:id="@+id/omitir_swipe"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Omitir"
android:textSize="16sp"
android:textStyle="bold"
android:layout_marginRight="30dp"
android:textColor="@color/colorBlack"
app:layout_constraintHorizontal_bias="1"
app:layout_constraintBottom_toBottomOf="@+id/textView"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toEndOf="@+id/textView"
app:layout_constraintTop_toTopOf="@+id/textView" />
</androidx.constraintlayout.widget.ConstraintLayout>

3是相同的，所以我只上传1，他们有相同的id，只使用1，我不知道这是否好，你能告诉我是否更改吗

3个碎片。kt kotlin:

import android.os.Bundle
import android.view.LayoutInflater
import android.view.View
import android.view.ViewGroup
import androidx.fragment.app.Fragment
import com.yr.iolite.R
class SwipeFragement1 : Fragment()
{
override fun onCreateView(
inflater: LayoutInflater,
container: ViewGroup?,
savedInstanceState: Bundle?
): View? {
return inflater.inflate(R.layout.fragment_splash_screen_1, container, false)
}
}

在3中只更改此数字fragment_splash_screen更改此数字

我展示3个片段xml:的活动

<?xml version="1.0" encoding="utf-8"?>

我没有任何错误，但当我取消注释setOnClickListener时，它不起作用，它会给我一个空指针异常错误，这是因为omit_swipe的id不在活动xml中，正如您在上面看到的那样，它在片段中。

Answer 1

您可以启动一个新的活动并从片段中完成当前活动。

class SwipeFragement1 : Fragment(){
override fun onCreateView(
inflater: LayoutInflater,
container: ViewGroup?,
savedInstanceState: Bundle?
): View? {
val view = inflater.inflate(R.layout.fragment_splash_screen_1, container, false)
view.findViewById<TextView>(R.id.omitir_swipe).setOnClickListener{
val intent = Intent(activity, MainActivity::class.java).apply {
putExtra(EXTRA_MESSAGE, "xd")
}
activity.startActivity(intent)
activity.finish()
}
return view
}
}
