【问题描述】：

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

【参考方案1】：

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
