为何ContextWrapper未在Activity中生效？是否与Localize有关？

在项目中使用Localize时，遇到ContextWrapper无法应用到Activity的问题，无更多附加描述。

相关代码实现 #

MainScreenActivity类 #

class MainScreenActivity : BaseActivity() {
...
    override fun fetchStringResourceKeys(): Map<Int, String> {
        return ResourceKeys::class.java.fields.associate { field: Field -> 
            field.getInt(null) to field.name 
        }
    }

    override fun attachBaseContext(newBase: Context) {
        val updatedThemeContext = newBase.getDependencies<MainActivityDependencies>()
            .themeManager
            .applyTheme(newBase)
        super.attachBaseContext(LocalizationContextWrapper.wrap(updatedThemeContext))
    }
...
}

BaseActivity抽象类 #

abstract class BaseActivity : AppCompatActivity() {
...
    abstract fun fetchStringResourceKeys(): Map<Int, String>

    override fun attachBaseContext(newBase: Context) {
        val customContextWrapper = ResourceKeyContextWrapper(
            baseContext = newBase,
            stringResourceKeys = fetchStringResourceKeys(),
        )
        super.attachBaseContext(customContextWrapper)
    }
...
}

ResourceKeyContextWrapper类 #

internal class ResourceKeyContextWrapper(
    baseContext: Context,
    private val stringResourceKeys: Map<Int, String>,
) : ContextWrapper(baseContext) {
    override fun getResources(): Resources {
        val originalResources = super.getResources()
        return CustomResources(
            originalResources = originalResources,
            stringResourceKeys = stringResourceKeys,
        )
    }
}

CustomResources类 #

internal class CustomResources(
    originalResources: Resources,
    private val stringResourceKeys: Map<Int, String>,
) : Resources(originalResources.assets, originalResources.displayMetrics, originalResources.configuration) {

    override fun getString(@StringRes id: Int): String = 
        stringResourceKeys[id] ?: super.getString(id)

    override fun getString(@StringRes id: Int, vararg formatArgs: Any?): String {
        return stringResourceKeys[id] ?: super.getString(id, *formatArgs)
    }

    override fun getText(id: Int): CharSequence = 
        stringResourceKeys[id] ?: super.getText(id)
}

已尝试的解决方案 #

• 完全移除RootActivity中的相关调用
• 反复检查fetchStringResourceKeys，确认其返回内容正常
• 调用attachBaseContext2代理并对其应用包装
• 将包装应用到ApplicationContext，但无法获取字符串键
• 跳过Localize包装调用
