插件中 getIdentifier("status_bar_height", "dimen", "android")获取状态栏高度抛出ResoureNotFound

[threeloe]

问题详细描述 Detailed description of the problem

int resourceId = context.getResources().getIdentifier("status_bar_height", "dimen", "android"); return context.getResources().getDimensionPixelSize(resourceId); 如上使我们常见的获取系统状态栏高度的一种做法，我的插件中刚好有这样的代码。然后编译运行就会报.Resources$NotFoundException

我去掉build.gradle中的apply plugin: 'replugin-plugin-gradle'之后，就不会报错。

目前我已经发现通过反射来获取就不会报错， Class<?> clazz = Class.forName("com.android.internal.R$dimen"); Object object = clazz.newInstance(); int id = Integer.parseInt(clazz.getField("status_bar_height") .get(object).toString()); statusBarHeight = context.getResources().getDimensionPixelSize(id);

复现问题步骤 Steps to reproduce the problem

1. 在插件中的AppcompatActivtiy中使用如上获取状态栏高度的代码
2. 编译成apk，然后运行到这里就会报错，说找不到资源
3. 如果不使用插件编译就不会报错

你尝试用宿主的上下文试试，你这好像是插件的上下文

出现这个问题的原因是，Gradle插件，在编译期对插件中 Resource.getIdentifier() 的使用做了替换，详见：

https://github.com/Qihoo360/RePlugin/blob/dev/replugin-plugin-gradle/src/main/groovy/com/qihoo360/replugin/gradle/plugin/injector/Injectors.groovy https://github.com/Qihoo360/RePlugin/tree/dev/replugin-plugin-gradle/src/main/groovy/com/qihoo360/replugin/gradle/plugin/injector/identifier

下一版本我们会修复这个问题。

请先使用反射的方式吧 。

感谢。

这个问题，在2.3.0上获取到的状态栏高度为0

[langxuelang]

@cundong 可否提供一下解决思路，我们自己修改下你们的代码。

修改 plugin gradle 如果第三个参数是 android 则不替换成插件的包名

1.方法一，使用反射宿主里的工具类

try { /* 在宿主里创建Utils类 public class Utils { public static int getIdentifier(Context context,String name, String defType, String defPackage){ if (context == null) return 0; return context.getResources().getIdentifier(name,defType,defPackage); } } */ float barHeight = -1; Class claz = RePlugin.getHostClassLoader().loadClass("com.zcm.host.demo.Utils"); Method method = claz.getMethod("getIdentifier", Context.class,String.class,String.class,String.class); Object heightId = method.invoke(null,getBaseContext(),"status_bar_height", "dimen", "android"); int heightIdInt = Integer.valueOf(heightId+""); if (heightIdInt != 0){ barHeight = getResources().getDimension(heightIdInt); } Log.i("ZCM_plugin","heightId:"+heightId+",barHeight:"+barHeight); }catch (Exception e){ e.printStackTrace(); }

2.方法二 修改gradle 插件 replugin-plugin-gradle/src/main/groovy/com/qihoo360/replugin/gradle/plugin/injector/identifier/GetIdentifierExprEditor.groovy 修改为 m.replace('{ $3 = "android".equalsIgnoreCase($3)? $3 : "' + CommonData.appPackage + '"; ' + '$_ = $proceed($$);' + ' }')

@zhangcb666 大佬修改gradle插件怎么编译啊
