在将自己写的工具打成.jar包的时候,有时候会需要引用到res中的资源,这时候不能将资源一起打包,只能通过反射机制动态的获取资源.

特别用在自己定义一个工具将其打成.jar包时,特别注意资源的获取

1、封装成一个工具类 

package com.cp.utils;
import android.content.Context;
public class CPResourceUtil {
public static int getLayoutId(Context paramContext, String paramString) {
return paramContext.getResources().getIdentifier(paramString, "layout",
paramContext.getPackageName());
}
public static int getStringId(Context paramContext, String paramString) {
return paramContext.getResources().getIdentifier(paramString, "string",
paramContext.getPackageName());
}
public static int getDrawableId(Context paramContext, String paramString) {
return paramContext.getResources().getIdentifier(paramString,
"drawable", paramContext.getPackageName());
}
public static int getStyleId(Context paramContext, String paramString) {
return paramContext.getResources().getIdentifier(paramString,
"style", paramContext.getPackageName());
}
public static int getId(Context paramContext, String paramString) {
return paramContext.getResources().getIdentifier(paramString,"id", paramContext.getPackageName());
}
public static int getColorId(Context paramContext, String paramString) {
return paramContext.getResources().getIdentifier(paramString,
"color", paramContext.getPackageName());
}
public static int getArrayId(Context paramContext, String paramString) {
return paramContext.getResources().getIdentifier(paramString,
"array", paramContext.getPackageName());
}
}

2、资源的获取

<string name="version_update_schedule">已下载%1$s请稍等&#8230;</string>
String text=mContext.getResources().getString(CPResourceUtil.getStringId(mContext, "version_update_schedule"));

TextView.setText(String.format(text, p+”%”));

version_update_schedule 是string文件中name
