Android 使用customview在Dialogfragment中进行ViewBinding
我有一个关于在使用自定义视图的对话框片段中使用Android 使用customview在Dialogfragment中进行ViewBinding,android,android-dialogfragment,android-dialog,android-viewbinding,Android,Android Dialogfragment,Android Dialog,Android Viewbinding,我有一个关于在使用自定义视图的对话框片段中使用viewBinding的问题。有没有一个标准的方法可以做到这一点 我的代码使用findViewById()作为对话框片段,但我希望使用viewbinding,因为这是我项目其余部分的标准 class WifiHandlerDialogFragment(private val wifiErrorType: Int): DialogFragment() { private var _binding: DialogWifiHandlerBinding?
viewBinding
的问题。有没有一个标准的方法可以做到这一点
我的代码使用findViewById()
作为对话框片段,但我希望使用viewbinding,因为这是我项目其余部分的标准
class WifiHandlerDialogFragment(private val wifiErrorType: Int): DialogFragment() {
private var _binding: DialogWifiHandlerBinding? = null
// This property is only valid between onCreateView and
// onDestroyView.
private val binding get() = _binding!!
override fun onCreateDialog(savedInstanceState: Bundle?): Dialog {
_binding = DialogWifiHandlerBinding.inflate(LayoutInflater.from(context))
val dialog = activity?.let {
Dialog(it)
}
if(dialog != null) {
dialog.window?.requestFeature(Window.FEATURE_NO_TITLE)
dialog.window?.setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN)
dialog.setContentView(R.layout.dialog_wifi_handler)
dialog.window?.setBackgroundDrawable(ColorDrawable(Color.TRANSPARENT))
val positiveButton = dialog.findViewById<Button>(R.id.positive_button) // really want to change this to use binding
val closeButton = dialog.findViewById<Button>(R.id.close_button) // really want to change this to use binding
val dialogMessage = dialog.findViewById<TextView>(R.id.dialog_message)
positiveButton.setOnClickListener {
startActivity(Intent(Settings.ACTION_WIFI_SETTINGS))
}
closeButton.setOnClickListener {
dismiss()
}
dialogMessage.text = when (wifiErrorType) {
1 -> getString(R.string.connection_dialog_op1)
2 -> getString(R.string.connection_dialog_op2)
3 -> getString(R.string.connection_dialog_op3)
else -> getString(R.string.error)
}
}
return dialog!!
}
override fun onDestroyView() {
super.onDestroyView()
_binding = null
}
}
类WifiHandlerDialogFragment(private val wifiErrorType:Int):DialogFragment(){
私有变量绑定:DialogWifiHandlerBinding?=null
//此属性仅在onCreateView和之间有效
//onDestroyView。
private val binding get()=\u binding!!
重写FunonCreateDialog(savedInstanceState:Bundle?:对话框){
_binding=对话框wifihandlerbinding.flate(LayoutInflater.from(上下文))
val对话框=活动?让我们{
对话(it)
}
如果(对话框!=null){
dialog.window?.requestFeature(window.FEATURE\u NO\u TITLE)
dialog.window?.setFlags(WindowManager.LayoutParams.FLAG_全屏,WindowManager.LayoutParams.FLAG_布局_屏幕)
dialog.setContentView(R.layout.dialog\u wifi\u处理程序)
dialog.window?.setBackgroundDrawable(可彩色绘制(彩色.透明))
val positiveButton=dialog.findViewById(R.id.positive_按钮)//是否确实要将其更改为使用绑定
val closeButton=dialog.findviewbyd(R.id.close_button)//是否确实要将其更改为使用绑定
val dialogMessage=dialog.findviewbyd(R.id.dialog\u消息)
positiveButton.setOnClickListener{
startActivity(意图(设置、动作\u WIFI\u设置))
}
closeButton.setOnClickListener{
解雇
}
dialogMessage.text=何时(wifiErrorType){
1->getString(R.string.connection\u对话框\u op1)
2->getString(R.string.connection\u对话框\u op2)
3->getString(R.string.connection\u对话框\u op3)
else->getString(R.string.error)
}
}
返回对话框!!
}
重写onDestroyView(){
super.onDestroyView()
_binding=null
}
}
我试图在onCreateDialog()
函数中使用binding.closebutton
,但我们没有工作(我假设是由于片段生命周期)
我已研究过这些问题:
但仍然没有找到实现这一点的最佳方法(这也是我第一次使用kotlin synthetics的
viewbinding
。修复。只是没有将内容视图设置为binding.root
。现在一切正常
class WifiHandlerDialogFragment(private val wifiErrorType: Int): DialogFragment() {
private var _binding: DialogWifiHandlerBinding? = null
// This property is only valid between onCreateView and
// onDestroyView.
private val binding get() = _binding!!
override fun onCreateDialog(savedInstanceState: Bundle?): Dialog {
_binding = DialogWifiHandlerBinding.inflate(LayoutInflater.from(context))
val dialog = activity?.let {
Dialog(it)
}
if(dialog != null) {
dialog.window?.requestFeature(Window.FEATURE_NO_TITLE)
dialog.window?.setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN)
dialog.window?.setBackgroundDrawable(ColorDrawable(Color.TRANSPARENT))
dialog.setContentView(binding.root)
binding.positiveButton.setOnClickListener {
startActivity(Intent(Settings.ACTION_WIFI_SETTINGS))
}
binding.closeButton.setOnClickListener {
dismiss()
}
binding.dialogMessage.text = when (wifiErrorType) {
1 -> getString(R.string.connection_dialog_op1)
2 -> getString(R.string.connection_dialog_op2)
3 -> getString(R.string.connection_dialog_op3)
else -> getString(R.string.error)
}
}
return dialog!!
}
override fun onDestroyView() {
super.onDestroyView()
_binding = null
}
}
