如何在Android的Strings.xml中搜索字符串? [英] How to search for a String in Android's Strings.xml?

问题描述

我尝试了以下答案:如何搜索内容存储在XML文件中的字符串?:

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打电话的:

and I'm calling from Java like this:

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

但是所有变量我都得到ERROR.我正在记录它们，只是为了查看它们是否匹配我的strings.xml中的字符串并且它们确实匹配.例如我有

but I get ERROR for all variables. I'm logging them just to see if they match strings in my strings.xml and they do. For example I have

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

它说

gonna search for distortion
found: null

推荐答案

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
            }
        }
