【问题描述】:
我创建了接受片段的自定义视图。所以,后来我的自定义视图有动态内容(片段)。但是添加片段时出现以下错误。
原因:java.lang.IllegalArgumentException:没有为片段 SampleFragment{470c924 #0 id=0x7f080058} 找到 id 0x7f080058 (android.amanah.com.amanah:id/flContent) 的视图
em>这是我的自定义视图:
class AmBottomSheet(context: Context, attributeSet: AttributeSet?) : ConstraintLayout(context, attributeSet) {
private val state = State()
init {
LayoutInflater.from(context)
.inflate(R.layout.layout_bottom_sheet, this, true)
}
fun bind(newState: State.() -> Unit) {
state.apply(newState)
render(state)
}
private fun render(state: State) {
tvTitle.text = state.title
if (state.subTitle != null) {
tvSubTitle.text = state.subTitle
} else {
tvSubTitle.visibility = GONE
}
ivClose.setOnClickListener {
state.closeClickListener?.invoke(it)
}
attachContentFragment()
}
private fun attachContentFragment() {
val transaction = state.supportFragmentManager?.beginTransaction()
transaction?.replace(R.id.flContent, state.layoutContent)
transaction?.commit()
}
class State {
var title: String? = null
var subTitle: String? = null
var closeClickListener: (View?.() -> Unit)? = null
var supportFragmentManager: FragmentManager? = null
var layoutContent: Fragment? = null
}
}
我这样称呼我的自定义视图:
...
bottomSheetView.bind {
title = "Informasi"
subTitle = "We can even add some listeners to the BottomSheet and for example do something when the dialog is dismissed"
closeClickListener = {
bottomSheetDialog.dismiss()
}
supportFragmentManager = getSupportFragmentManager()
layoutContent = SampleFragment.newInstance()
}
...
我的 xml 在我的自定义视图 (layout_bottom_sheet.xml) 布局中作为片段容器,如下所示:
...
<FrameLayout
android:id="@+id/flContent"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="@dimen/standard_margin_x2"
android:background="@color/colorSlate"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="@+id/tvSubTitle"
app:layout_constraintVertical_bias="0.0" />
...
为什么我的自定义视图找不到 flContent?
