Wow, this is one hell of a delayed post ! But nevertheless ...
A lot of times, when we try to templatize / automate a product, we face the problem of converting a string to its corresponding resource id. For example, a simple input from the user for the drawable name that he/she would want to select for a button. This input will essentially be in the format of a string. Now to map this string to the corresponding drawable id is the task we propose the following solution -
public static int getResId(String variableName, Context context, Class<?> c) {
try {
Field idField = c.getDeclaredField(variableName);
return idField.getInt(idField);
} catch (Exception e) {
e.printStackTrace();
return -1;
}
}
The usage will be -
getResId("icon", context, Drawable.class);
Thats all for now folks !
