由网友(冷城少年终享孤独)分享简介：我有code像tthis：I have code like tthis:String s = "replace__menu__" + data.imageid + ".png";int RID = this.getApplicationContext().getResources().getIdentifier(...

我有code像tthis：

I have code like tthis:

String s = "replace__menu__" + data.imageid + ".png";
int RID = this.getApplicationContext().getResources().getIdentifier(s, "drawable-hdpi", getPackageName());

在的String = 的指令设置一个值，该值是一样的名字在我的RES /绘制，华电国际文件之一。但是，返回的值集的 RID 应用于值的 0 的

The String s = instruction sets a value that is the same as one of names in my res/drawable-hdpi folder. However, the returned value sets RID to the value 0

任何想法，为什么我的code不工作？难道我做错了什么？

Any idea why my code is not working? Am I doing something wrong?

推荐答案

试试这个

String s = "replace__menu__" + data.imageid;  // image name is needed without extention
int RID = this.getApplicationContext().getResources().getIdentifier(s, "drawable", getPackageName());
