我有一个包含4个容器(LinearLayouts)的视图。每个容器将根据数据填充内容。 (每个内容视图都以一种布局夸大并添加到容器中)
以前,我在加载数据时对每个布局进行了夸大之后调用了ButterKnife.bind(this, view)
。现在,我想摆脱ButterKnife,转而使用kotlinx合成视图绑定。
我的问题是,第一次创建视图并进行设置时一切正常。当我刷新视图时,大多数视图为空(以前不为空,也不应该为空)。
某些代码:
private fun refresh() {
//Get data...then...
//Reset containers
topup_container_one.removeAllViews()
topup_container_two.removeAllViews()
topup_container_three.removeAllViews()
topup_container_four.removeAllViews()
lateinit var contentOne: View
lateinit var contentTwo: View
lateinit var contentThree: View
lateinit var contentFour: View
val layoutInflater = context!!.getSystemService(Context.LAYOUT_INFLATER_SERVICE) as LayoutInflater
if (someCondition) {
contentOne = layoutInflater.inflate(R.layout.layout1, topup_container_one, false)
contentTwo = layoutInflater.inflate(R.layout.layout2, topup_container_two, false)
contentThree = layoutInflater.inflate(R.layout.layout3, topup_container_three, false)
contentFour = layoutInflater.inflate(R.layout.layout4, topup_container_four, false)
} else {
// some other sort order, same principle
}
topup_container_one.addView(contentOne)
topup_container_two.addView(contentTwo)
topup_container_three.addView(contentThree)
topup_container_four.addView(contentFour)
}
布局:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<LinearLayout
android:id="@+id/topup_container_one"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
</LinearLayout>
//same for two, three, four
</LinearLayout>
关于该视图混乱,我有什么可以做的吗?也许会“召回”视图绑定?
答案 0 :(得分:0)
在为每个容器充气后再次手动绑定视图时,它会起作用。
所以,我要做什么:
private var buttonVoucherVoiceInput: AppCompatImageButton? = null
private var editTextVoucher: EditText? = null
private var textInputLayoutVoucher: TextInputLayout? = null
private var buttonVoucherSubmit: Button? = null
//And many many more
private fun refresh() {
///...
topup_container_one.addView(contentOne)
topup_container_two.addView(contentTwo)
topup_container_three.addView(contentThree)
topup_container_four.addView(contentFour)
//Find views again
editTextVoucher = view!!.findViewById(R.id.topup_edittext_voucher)
buttonVoucherSubmit = view!!.findViewById(R.id.topup_button_voucher_submit)
textInputLayoutVoucher = view!!.findViewById(R.id.topup_til_voucher)
buttonVoucherVoiceInput = view!!.findViewById(R.id.topup_button_voucher_voice)
}
烦人,但又可以正常工作。我可以从项目中删除Butterknife。 (不要无礼,我喜欢):)
