[英]Remove LinearLayout with a button, which is inside this LinearLayout
I've created a custom linear layout within android studio.我在 android 工作室中创建了一个自定义线性布局。 This layout gets inflated into another vertical layout programatically.
此布局以编程方式膨胀为另一个垂直布局。 Now I want to map a button inside this layout, which can delete the whole object.
现在我想在这个布局里面给map一个按钮,里面可以删除整个object。 Here is my layout:
这是我的布局:
And as you can see the button "DELETE HERE" should remove the 3 items, time, weekday and the button itself.如您所见,“在此处删除”按钮应删除 3 个项目,时间、工作日和按钮本身。
This is my class and here这是我的 class 和这里
class AlarmCard @JvmOverloads constructor(
context: Context,
attrs: AttributeSet? = null,
defStyle: Int = 0,
defStyleRes: Int = 0,
) : LinearLayout(context, attrs, defStyle, defStyleRes) {
init {
LayoutInflater.from(context)
.inflate(R.layout.alarmcard, this, true)
btnDelete.setOnClickListener(){
**/* Call destructor or remove view !?!*/**
}
}
}
which get added to the linear layout with:它被添加到线性布局中:
val monday = AlarmCard(this)
alarmCards.addView(monday)
The problem is for me how can I delete the object with a button?问题是我如何用按钮删除 object? I tried using alarmCards.removeView(this) within btnDelete.setOnClickListener() but It crashes.
我尝试在 btnDelete.setOnClickListener() 中使用 alarmCards.removeView(this) 但它崩溃了。 :(
:(
Thank you!!谢谢!!
Try this:尝试这个:
btnDelete.setOnClickListener {
(getParent() as? ViewGroup)?.removeView(this@AlarmCard)
}
