Android uses Getidentifier () to get the resource ID

Mainly by two methods:

1, do not put the picture under the res/drawable, but stored in the SRC package (such as: Com.drawable.resource), in this case, the method of invocation is:

String Path = "Com/drawable/resource/imagename.png"; InputStream is = getClassLoader (). getResourceAsStream (Path);D Rawable.createfromstream (IS, "src");

2, if you still want to directly use the res/drawable in the picture, [ Assuming the creation of the project, fill in the package name: Com.test.image] need to pass the following method:

int resID = Getresources (). Getidentifier ("ImageName", "drawable", "Com.test.image");D rawable image = Getresources (). Getdrawable (ResID);
