NavGraph字符串类型默认参数被解析为数字的异常问题

当传递纯数字格式的字符串作为Fragment的默认参数时，参数未被正确接收为原字符串，出现异常转换：

复现步骤 #

• 将目标Fragment设置为NavGraph的startDestination
• 为该Fragment添加字符串类型的默认参数，且参数值仅包含数字
  • 值较短时（如"987987"）可正常接收
  • 值约15位时（例如"987987987987987"），会被接收为"9.8798797E14"
  • 值约30位时，会被接收为"infinity"

使用的Navigation版本：2.5.3

NavGraph 配置 #

<?xml version="1.0" encoding="utf-8"?>
<navigation xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/home_nav"
    app:startDestination="@id/verifyProductFragment">
    <fragment
        android:id="@+id/verifyProductFragment"
        android:name="com.app.fragments.VerifyProductFragment"
        android:label="VerifyProductFragment" >
        <argument android:name="imeiNo"
            app:argType="string"
            android:defaultValue="987987987987987"/>
    </fragment>
</navigation>

Fragment 代码 #

class VerifyProductFragment : Fragment() {

    private val args by navArgs<VerifyProductFragmentArgs>()

    override fun onCreateView(
        inflater: LayoutInflater,
        container: ViewGroup?,
        savedInstanceState: Bundle?
    ) = ComposeView(requireContext()).apply {
        setContent {
            Log.e("data", args.imeiNo)
        }
    }

}

依赖配置 #

def nav_version = "2.5.3"
implementation "androidx.navigation:navigation-fragment-ktx:$nav_version"
implementation "androidx.navigation:navigation-ui-ktx:$nav_version"
implementation "androidx.navigation:navigation-dynamic-features-fragment:$nav_version"
