Question

I need to store the link to the image, which user has chosen. The sources of the images are files, contact icons and resources drawables (I need drawables since I provide different images for different resolutions/densities). For the purpose of unification I store it in URI, and consequently this URI may be pointing to a file (file://), to content provider or to resource (android.resource://...). Here is how the URI pointing to drawable with id=2130837534 looks like:

android.resource://my.packagename/2130837534

除非 R.java 中的代号被重新生成,否则它仍然有效。因此,有没有办法可以阻止SDK更改某些 R.java ids 值?

Answer 1

不,你不能去,你应该去。如果你能清楚地描述你的问题,也许还有别的解决办法。

以这种方式将您的资源名保存在文件中。

icon_profile_1 icon_profile_2

当你需要资源ID时,请这样做。

int resID = getResources().getIdentifier("icon_profile_1", "drawable","your_package_name");

收看 (java.lang.String,java.lang.string.String,java.lang.String,java.lang.String,java.lang.String,java.lang.string,java.tring.string.string)

Answer 2

由于R.java是自动生成的,因此无法从操作中限制它, 因为当您的工程被清理或编译时, 它会自动生成。

Answer 3

这是不可能的在和机器人,因为R. java是自动化的,你不能做任何事情。
