获取drawable下的icon的值。
方法一:
try{ Field field=R.drawable.class.getField("icon"); int i= field.getInt(new R.drawable()); Log.d("icon",i+""); }catch(Exception e){ Log.e("icon",e.toString()); }
方法二:
Resources res=getResources(); int i=res.getIdentifier("icon","drawable",getPackageName()); Log.i("res",Integer.toString(i));
