我试过这个答案：How to search content of strings stored in XML file?:

companion object {
        val TAG: String = "EffectsDescription"
        fun fromStringsXml(string: String, context: Context): String {
            val ss = string.toLowerCase().replace(" ", "_");
            Log.d(TAG, "gonna search for " + ss);
            val s = searchForString(ss, context);
            Log.d(TAG, "found: " + s);
            return s ?: "ERROR"
        }

        private fun searchForString(message: String, context: Context): String? {
            return try {
                val resId: Int = context.resources.getIdentifier(message, "string", context.packageName)
                Resources.getSystem().getString(resId)
            } catch (e: Exception) {
                null
            }
        }
    }

我是这样从 Java 调用的：

EffectDescription.Companion.fromStringsXml(effectOrCategory, MainActivity.this.getApplicationContext())

但我得到所有变量的ERROR。我正在记录它们只是为了查看它们是否与我的 strings.xml 中的字符串匹配并且它们匹配。例如我有

<string name="distortion">Distortion</string>

它说

gonna search for distortion
found: null

修复：

fun fromStringsXml(string: String, context: Context): String {
            val ss = string.toLowerCase().replace(" ", "_");
            Log.d(TAG, "gonna search for " + ss + " with packageName " + context.packageName);
            val s = searchForString(ss, context);
            Log.d(TAG, "found: " + s);
            return s ?: "ERROR"
        }

        private fun searchForString(message: String, context: Context): String? {
            return try {
                val resId: Int = context.resources.getIdentifier(message, "string", context.packageName)
                Log.d(TAG, "redID: $resId")
                context.resources.getString(resId)
            } catch (e: Exception) {
                null
            }
        }
