为什么不叫radiogroup

问题描述

我有一个带有 3 个单选按钮的单选组。当我点击单选按钮时，动画正在改变，但 oncheckedchangelistener 没有被调用。没有任何日志正在打印，所以我认为它一定是侦听器，但我看不出任何错误。我遵循了几个例子，但一切都几乎相同。这是我的代码：

    override fun onViewCreated(view: View,savedInstanceState: Bundle?) {
        super.onViewCreated(view,savedInstanceState)
      

        viewmodel.myTracksShort.observe(viewLifecycleOwner) { state ->
            when (state) {
                is DataState.Success -> {
                    shortList = state.data.items!!
                    if (checkedRadioButton == 0){
                        mostListenedAdapter.setTracksList(shortList)
                    }
                    setScreenToSuccess()
                }
                is DataState.Fail -> {
                }
            }
        }
        viewmodel.myTracksMedium.observe(viewLifecycleOwner) { state ->
            when (state) {
                is DataState.Success -> {
                    mediumList = state.data.items!!
                    setScreenToSuccess()
                }
                is DataState.Fail -> {
                }
            }
        }
        viewmodel.myTracksLong.observe(viewLifecycleOwner) { state ->
            when (state) {
                is DataState.Success -> {
                    longList = state.data.items!!
                    setScreenToSuccess()
                }
                is DataState.Fail -> {
                }
            }
        }
        binding.rg.setonCheckedchangelistener {
                group,checkedId ->
            Log.d(TAG,"onViewCreated: $checkedId")
            when (checkedId) {
                R.id.rb1 -> {
                    Log.d("TAG","onViewCreated: short")
                    if (this::shortList.isInitialized) {
                        mostListenedAdapter.setTracksList(shortList)
                        checkedRadioButton = 0
                    }
                }
                R.id.rb2  -> {
                    if (this::mediumList.isInitialized) {
                        Log.d("TAG","onViewCreated: m")
                        mostListenedAdapter.setTracksList(mediumList)
                        checkedRadioButton = 1
                    }
                }
                R.id.rb3 -> {
                    if (this::longList.isInitialized) {
                        Log.d("TAG","onViewCreated: l")
                        mostListenedAdapter.setTracksList(longList)
                        checkedRadioButton = 2
                    }
                }
                else -> Log.d(TAG,"onViewCreated: else")
            }
        }
   

还有我的 XML 文件：

        <RadioGroup
            android:layout_width="match_parent"
            android:layout_height="30dp"
            android:id="@+id/rg"
            android:weightSum="9"
            android:checkedButton="@id/rb1"
            android:gravity="center_vertical"
            android:orientation="horizontal"
            android:background="@color/colorPrimary">
            <RadioButton
                android:layout_width="0dp"
                android:layout_height="30dp"
                android:id="@+id/rb1"
                android:layout_weight="3"
                android:text="@string/short_term"
                android:gravity="center"
                android:background="@drawable/radio_flat_selector"
                android:button="@android:color/transparent"
                android:textColor="@color/radio_flat_text_selector"/>
            <RadioButton
                android:layout_width="0dp"
                android:layout_height="30dp"
                android:id="@+id/rb2"
                android:gravity="center"
                android:layout_weight="3"
                android:text="@string/mid_term"
                android:background="@drawable/radio_flat_selector"
                android:button="@android:color/transparent"
                android:textColor="@color/radio_flat_text_selector"/>
            <RadioButton
                android:layout_width="0dp"
                android:layout_height="30dp"
                android:id="@+id/rb3"
                android:gravity="center"
                android:layout_weight="3"
                android:text="@string/long_term"
                android:background="@drawable/radio_flat_selector"
                android:button="@android:color/transparent"
                android:textColor="@color/radio_flat_text_selector"/>
        </RadioGroup>

解决方法

对于任何反击相同错误的人：我将我的 Radio Group 的 ID 重命名为 radioGroup 并解决了。
