反射的调用接口的写法：

import java.lang.reflect.InvocationTargetException;
import java.lang.reflect.Method;

public  static <T> T callStaticObjectMethod(Class<?> clazz, Class<T> returnType, String method, Class<?>[] parameterTypes,
                                           Object... values)
        throws NoSuchMethodException, SecurityException, IllegalAccessException, IllegalArgumentException, InvocationTargetException {
    Method declaredMethod = clazz.getDeclaredMethod(method, parameterTypes);
    declaredMethod.setAccessible(true);
    return (T) declaredMethod.invoke(null, values);
}

private static final String PHONE_ENCRYPT_UTIL_CLASS = "com.miui.enterprise.PhoneEncryptUtil";
private static boolean isEncryptedNumber(String number) {
    try {
        Class phoneEncryptUtil = Class.forName(PHONE_ENCRYPT_UTIL_CLASS);
        return callStaticObjectMethod(phoneEncryptUtil, boolean.class, "isEncryptedNumber",
                new Class[]{String.class}, number);
    } catch (Exception e) {
        return false;
    }
}
