Question

I created a class to extend KeyEvent:

public class myKeyEvent extends KeyEvent {
    public static final int MY_KEYCODE_01 = KeyEvent.KEYCODE_A;
    //...
    public static final int MY_KEYCODE_30 = KeyEvent.KEYCODE_Z;
}

Now, i want to get the Integer value by the variable name (eg. “MY_KEYCODE_01” should return integer value KeyEvent.KeyCODE_A) from another class (another file).

I tried to:

try{
    Class cls = myKeyEvent.class.getClass();
    Field field = cls.getDeclaredField("MY_KEYCODE_01");
    int value = (Integer) field.get(cls);
    Log.v("TAG", "Field value is " + value);

} catch (NoSuchFieldException e) {
    Log.e("TAG", "Field either doesn't exist or is not public: " + e.toString() );
}

In LogCat:

Field either doesn't exist or is not public: java.lang.NoSuchFieldException: MY_KEYCODE_01

How can I do it?

Answer 1

The class is myKeyEvent.class if you do myKeyEvent.class.getClass() you are getting the class of the class object which is Class. Drop the getClass()

You should be able to see the class is not correct in a debugger.
